Since this comment was written in 1994, the legal defenses to birth related brachial plexus malpractice claims have changed to conform to the applicable standard of care. Medical literature authored by Gonic speaks to the amount of force necessary to cause a brachial plexus injury. This has given rise to practitioners facing a medical malpractice action testifying that they did not apply a force sufficient to cause the injury. Other literature continues to blame birth related brachial plexus injuries on the forces of labor and/or fetal mal formation. These articles, published in the leading scientific journals, are always based upon the review of the observations of the treating Obstetrician, the physician who delivered the child with a brachial plexus injury. These articles have never questioned the treating physicians observations as being influenced by the doctors personal and financial self-interest in not being found the cause of the injury. Forth this reason alone, the conclusions reached by these articles must be questioned as must the credibility of the physicians relying upon such findings.

It is also very noteworthy that surgical developments in the repair of damaged brachial plexus nerves at birth is now more then ever a viable option for the care and treatment of brachial plexus birth related injuries.

A Comment on the Trial of
Brachial Plexus/Erb's Palsy Medical Malpractice Cases


Douglas M. Wade, L.L.M.*
1994

Preface


The purpose of this writing is to provide with the experience gained by Evidence Technologies, Inc. in the presentation and trial of Brachial Plexus/Erb's Palsy medical malpractice actions. In the six months prior to this writing, E.T.I. was involved in nine cases where obstetrical mismanagement gave rise to a permanent Erb's Palsy and one case involving a temporary Erb's Palsy. E.T.I. has had opportunity to observe how different trial attorneys and law firms present Erb's Palsy related litigation. The following is an analysis of the defenses employed as well as suggestions which may assist in preparing for a birth related brachial plexus injury/Erb's Palsy medical malpractice trial.

Please note that the following represents the authors opinion only. E.T.I. in no way warrants or guarantees the materials contained herein.

Definitions:

Brachial Plexus Nerve: The grouping of nerves connecting the C4 to Th1 junctions of the spinal cord to the left and right arms.
 

Erb's Palsy: Erb's Palsy, also known as Erb-Duchenne paralysis, describes a partial paralysis of the brachial plexus nerve caused by stretching, tearing and/or evulsion at birth. The Palsy was originally identified by Wilhelm Heinrich Erb, a German neurologist a century ago.

Fetal Reserves: The term fetal reserves refers to the amount of stress a fetus can withstand before the fetus becomes acidotic and suffers irreversible brain damage. The concept arises from an imbalance in the bodies Ph levels. Ph refers to the chemical balance between base and acid. Low pH levels are referred to medically as acidocis. When a fetus becomes acidotic, it's ability to metabolize glucose decreases to such an extent that the fetus will, without intervention, become so acidotic that its internal organs will become damaged, it will the suffer brain damage, and if not correct, the fetus will die. Factors influencing fetal reserves include repetitive late decelerations, the presence of pre-eclampsia, a prolonged second stage of labor, and delays in delivery in excess of five minutes after delivery of the fetus' head. Low fetal reserves are reflected in low one minute and five minute APGAR scores and low umbical cord blood gas measurements.

Macrosomia: A fetus whose weight (either estimated or actual) is greater then or equal to 4,500 grams. [William's Obstetrics, 19th Edition at p. 508.]

Meconium: A fetal bowl movement. Meconium clouds the amniotic fluid and may stain the fetus' skin (a process referred to as meconium staining). Meconium is dark green and progressively turns brown as time passes. The presence of meconium maybe a sign of fetal distress and maybe associated with fetal trauma. Meconium maybe a clear indication of reduced fetal reserves if the trauma that gave rise to the meconium release was within close proximity to the time of delivery.

A Note on Pronoun Usage: In order to avoid usage of words such as "s/he" and "his/her" in this writing, such references will only be made in the male gender. The selection of the male gender has not been predicated upon bias. Rather, E.T.I. Has yet to be involved in a permanent brachial plexus birth related injury case where the attending Obstetrician and/or expert Obstetricians were female.

Comment

Almost all permanent brachial plexus injuries are birth related. Birth related brachial plexus injuries are caused by the Obstetrician applying excessive downward or upward lateral traction to the baby's head and neck once it has presented during the course of delivery. In lay terms, the angle of presentation of the baby's shoulder prevents the baby from fitting through the birth canal. It is the position of the baby in relation to the mother which is known medically as Shoulder Dystocia.

To apply upward or downward lateral traction, the Obstetrician positions his/her hands on top of and below the baby's head and pulls the head down and out in the hopes of freeing the baby's shoulder which is blocked from delivery through the birth canal by the pubic symphysis.

Bilateral or Unilateral Shoulder Dystocia?

Shoulder Dystocias are either bilateral or unilateral in nature. The dystocia is bilateral when one of the baby's shoulders is prevented from entering the birth canal by the pubic symphysis while the other shoulder is likewise prevented from entering the birth canal by the mother's sacral promontory. A unilateral dystocia occurs when one of the baby's shoulders is prevented from entering the birth canal by the pubic symphysis.

 


 

Short of an Obstetrician placing a laparoscope with a camera inside the mother's womb, there is no way to determine whether a Shoulder Dystocia is bilateral or unilateral. As a plaintiffs attorney, it will be tempting to characterize the Shoulder Dystocia as bilateral in nature and thereby argue that because the Shoulder Dystocia was bilateral, the physician should have recognized this more severe impairment to viginal birth and acted to correct the problem in a more adroit manner. If the argument is made that the Shoulder Dystocia was bilateral, anticipate that defense expert medical witnesses will disagree with your expert witnesses and testify that the Shoulder Dystocia was unilateral in nature. Although the bilateral v. unilateral Shoulder Dystocia argument can be made at time of trial, E.T.I. recommends conceding that the Shoulder Dystocia was unilateral in nature in all but severely macrocosmic babies. For the purposes of this writing, severe macrosomia is defined as a delivery weight in excess of 5,000 grams. For cases where the baby's weight less then 5,000 grams, the bilateral v. unilateral argument merely serves to complicate the thrust of your case. However, in cases where(1) where the estimated fetal weight indicates severe macrosomia, (2) the baby in fact turned out to be severely macrocosmic or (3) the mother was an uncontrolled diabetic, we recommend arguing that the Shoulder Dystocia was in fact bilateral and the proper course of Obstetrical management was either performance of a Zavanelli Maneuver or a scheduled Caesarian section.

The Zavanelli maneuver involves pushing the babies head back into the uterus upon recognition that other management techniques will not relieve the dystocia and performing a crash Caesarian section. It is noteworthy that proper performance of this maneuver requires that the hospital where the birth occurs be equipped for this procedure i.e. has adequate surgical suits and personnel available. It is also noteworthy that in the entire United States, this procedure is performed only once or twice a year or one to two times per every four million deliveries.

Defense Verbiage

It is not uncommon for defense attorneys to coach their clients to avoid the use of certain terms believed to evoke a less than favorable response from jurors. Of particular interest are the terms "blocked," "brachial plexus injury," "dystocia," "permanent injury," "palsy," and "malpractice." The defense bar has placed enough weight on verbiage to have suggested wording disseminated throughout the medical community by having it placed in one of the leading medical articles on Shoulder Dystocia.

Dr. Jennett in his discussion, points out the desirability of using the term brachial plexus impairment instead of the term injury, which offers the opposing attorney, the opportunity to argue that the physician caused the injury. I add as alternatives dysfunction or the old term palsy. Good defensive record keeping requires cultivating our sensitivity implications of the words we use. [Dr. Carl Goetsch's comment in Jennett et. al. article at p. 1677.]


Expect the defense to substitute "acts not below the standard of care" for "malpractice," and "impairment" or "palsy" for "brachial plexus injury" or "injury to the brachial plexus," and "entrapment" for "blocked" and/or "dystocia." The following are excepts of trial testimony:

"I applied excessive downward force for this baby but, I did not commit malpractice." The change in verbiage suggests that acts which are below the standard of care do not rise to the level of malpractice.

"The birth gave rise to a brachial plexus "impairment" or the baby appears to have an "Erb's Palsy." Refusing to use the word injury acts to down play the severity of the injury.

"The baby's shoulder was "entrapped" by the symphasis." The change in verbiage suggests that the baby's shoulder was not blocked but rather the shoulder was drawn to and trapped by the symphasis. The Shoulder Dystocia was, therefore, an act of God.


To counter this tactic, bring Motions in Limine to clarify the terminology used by physicians. If the motion is denied, point out to the jury in your opening statement and closing arguments that the above-mentioned terminology is synonymous and that the defense has used these terms to distort the truth.

Defenses Common to Brachial Plexus/Erb's Palsy Birth Injury Cases

There are five defenses commonly used by defense counsel in brachial plexus/Erb's Palsy birth injury cases. These defenses are: (1) "act of God," (2) fetal mal formation/mal adaptation, (3) misstatement of the care and management rendered by the attending Obstetrician, (4) misstatement of the time between differential diagnosis of the Shoulder Dystocia and the time of delivery of the infant, and (5) the "Emergent Situation" defense.

The "Act of God" Defense

The "act of God" defense is the primary defense used to defend claims of permanent Erb's Palsy caused by the obstetrical mismanagement of a Shoulder Dystocia. Simply put, this defense argues that the dystocia or the "impairment to normal delivery" was "an act of God." In other words, God put the baby's shoulder in such a position that it could not be delivered without assistance. When the Obstetrician applied downward traction, he was merely doing his job, i.e. delivering the baby.

Most plaintiff attorneys counter the "act of God" defense with expert medical testimony provided by an OB/GYN stating that excessive lateral traction is below the applicable standard of care and that the injury suffered by the infant was, in his expert opinion, caused by excessive lateral traction applied during birth. Typically, attorneys provide the expert with a blow-up of a drawing or two illustrating the position of the brachial plexus nerve in relation to the baby's neck and arm and the expert will use hand gestures to indicate excessive lateral traction. It should be expected that defense expert witnesses will testify that the defendant Obstetrician did not apply excessive lateral traction and that the injury to plaintiff was not birth related. The conflicting testimony between plaintiff and defense expert medical witnesses creates a credibility contest between defense and plaintiff expert medical witnesses.

Although it is tempting to believe that the experts you hire will be more dynamic and credible than the defense experts, it is always preferable to try a case on facts which support your case rather then gamble a verdict solely on witness credibility. Determining an expert witnesses' credibility at the time of trial is complicated as a witnesses credibility may be influence by numerous factors: factors such as academic background, style of speech, level of preparation, ability to cope with cross-examination, the attitude of the judge, witness order, etc. In short, witness credibility is subjective and will vary depending upon to many variables to predict months in advance of trial. However, providing a tight, concrete case based upon detailed scientific fact will bolster your experts credibility irrespective of the other factors. In short, give your experts the ammunition they need to be persuasive.

The Fetal Mal Formation/Mal Adaptation Defense

The fetal mal formation/mal adaptation defense is predicated upon the notion that the brachial plexus injury was not in fact caused by excessive lateral traction but by "fetal mal formation" or "fetal mal adaptation." Fetal mal formation/mal adaptation, as the name suggests, argues that the fetus suffered the injury to the brachial plexus nerve prior to delivery. Fetal mal adaptation is caused by a deformity in the mother's womb.

Deformities of the mother's womb are caused by the presence of a large tumor, fibroid or cyst positioned so that it constricts the fetus' movements during gestation thereby preventing normal development of the brachial plexus nerve. Alternatively, the womb itself could be misshapen causing similar limitations on fetal movement.

The fetal mal formation/mal adaptation defense is used because it provides an explanation independent of the actions of the attending Obstetrician for the injury to the brachial plexus. Expect that defense expert witnesses will testify that the medical literature supports the fetal mal formation/mal adaptation theory. We at E.T.I. do not believe that the relevant medical literature supports this conclusion. The medical literature states that while mal formation is possible and has been documented, it is a very very rare occurrence. The medical literature puts forth the hypothesis that mal formation of the neck and shoulder almost always results in spontaneous abortion.

Countering the Fetal Mal Formation/Mal Adaptation Defense

We at E.T.I. suggest that plaintiff attorneys have an Independent Medical Examination (IME) performed on the Mother immediately prior to the discovery cut-off date. During the IME, the Obstetrician/Gynecologist will take a medical history of the plaintiffs mother to determine if any of the baby's parents or their family members have deformed brachial plexus nerves. So long as there is no genetic history of brachial plexus injury in the family, it should be possible to exclude the mal formation theory at trial.

Also, during the IME the physician will examine the mother for fibroids, cysts and tumors i.e. all possible causes of deformity of the mother's womb which might act to constrict the movement of the fetus during gestation. Once the IME has been performed, a Motion in Limine can be brought to exclude all references to fetal mal formation/mal adaptation during trial on the grounds that there is no basis in fact to suggest that fetal mal formation/mal adaptation was a medical possibility in the immediate matter. The performance of an IME on the mother, therefore, can prevent defense attorneys from raising the fetal mal formation/mal adaptation defense. Elimination of this defense should significantly simplify the trial.

Further Analysis of the "Act of God" and Fetal Mal Formation/Mal Adaptation Defenses

It is very common for the defense to raise several or even all of the five defenses at the time of trial. The "act of God" defense coupled with the "fetal mal adaptation/mal formation" defense is among the most common defense combinations. It is frequently used because it produces several results favorable to the defense. First, if the jury is pre-disposed to believe that the defendant physician did nothing wrong during the course of the delivery, these defenses provide three good excuses for a defense verdict. (1) Only God positions baby's in a mother's womb. (2) Fetal mal formation/mal adaptation is a scientific and possible cause of the brachial plexus injury and accompanying Erb's Palsy. (3) Layering the "act of God" and the fetal mal formation/mal adaptation defenses serves to create a credibility contest between medical expert witnesses thereby removing the case from trial on the merits of the medical issues.

The psychological effect on a jury of the layering of defenses is most interesting. Upon polling after trial, jurors have indicated the following: (1) that they accept the argument that the injury to the child was not birth related even though on a balance of the probabilities they believed that the injury was "most likely" birth related; (2) that they accepted the argument that the injury was merely an "act of God" even though they believed that the injury itself was birth related and in fact was caused by excessive downward lateral traction applied by the defendant; (3) jurors accept the defense experts testimony that the injury was not birth related. However, these jurors offered no explanation as to the cause of the injury.

The best way to counter layering of defenses, a tactic which confuses the issues to be decided by jurors, is simplification of the case. Wherever possible, eliminate potential defenses before they can be raised by the defense.

The Distortion of Management Practices Employed by Defendant Obstetricians

The third defense in Brachial Plexus/Erb's Palsy cases is that defendants will lie as to what was done to manage the Shoulder Dystocia. Distortion of the nature of the care rendered lends itself to the "act of God" and "fetal mal adaptation" defenses because it adds a layer of credibility to both theories even though most attorneys are able to point out some, if not all, of the defendant physicians lies and exaggerations to a jury. E.T.I. employees have witnessed a trial where the defendant physician changed his story as to what he did to manage the Shoulder Dystocia between his deposition and his trial testimony and his trial testimony on day 1 and on day 2. Plaintiffs successfully impeached the defendant on his contradicting testimony and successfully convinced the jury that the injury was caused by excessive downward lateral traction. Despite these successes, the jury reached a defense verdict. Do not overestimate the weight catching a physician in an outright lie will have on a jury. In today's climate of reform of the medical system, jurors are subscribing to the notion that medical malpractice awards are out of control and choose not to acknowledge that physicians can be self-serving. Merely identifying inconsistencies in a defendants testimony regarding the management practices employed within itself may not be enough to sway a jury.

Distortion of the Time Between Differential Diagnosis and Delivery of the Baby

Expect the defendant Obstetrician to falsify the medical records with respect to the time of delivery of the baby's head and the complete delivery of the baby. Defendant Obstetricians will attempt to increase the amount of time between differential diagnosis and delivery in order to support the fifth defense, that the defendant Obstetrician's actions during delivery were necessary to save the baby's life. In other words, by lengthening the time involved in this aspect of the delivery, the Obstetrician can argue that his actions were necessitated by an Obstetrical emergency.

Compare the attending nurses notes with the discharge summary written and/or dictated by the attending Obstetrician. It has been our experience that the nursing notes and physician summary will differ with respect to the management practices employed during the delivery. At the time of trial, explore in great detail the maneuvers performed by the defendant as noted in the medical records, delivery summary written or dictated by the defendant physician after the delivery, and the testimony the doctor gives at his deposition. Be sure to point out to the jury that the physician is not the only person in the delivery room responsible for creating the medical record. Create time lines noting the distinctions between the medical records, physician summary, defendant deposition, trial testimony, and Williams' Obstetrics. In all likelihood, the defendants testimony will get closer and closer to Williams' management strategy as time progresses. This fact should be pointed out to a jury as it will make jurors suspicious of the defendant and put his credibility at issue.


The "Emergent Situation" Defense

The most modern and potent defense utilized is the "Emergent Situation" defense. The defense arises from the notion, albeit incorrect and not supported by any medical literature, that there is a very very short amount of time for Obstetricians to manage a Shoulder Dystocia after making a differential diagnosis. [The differential diagnosis of Shoulder Dystocia is made once the baby's head presents in the "Turtle Sign " or nose down and the head is sucked slightly back into the birth canal.]

The defense will put forth the argument that because there is so little time with which to manage a Shoulder Dystocia, and because the risk of taking too long to relieve the Shoulder Dystocia is fetal brain damage, Obstetricians are justified in doing whatever is necessary to deliver the baby as quickly as possible. In other words, it is OK to apply excessive lateral traction and deliberately sacrifice an arm to save a brain.

Central to the "Emergent Situation" defense is the amount of time between the differential diagnosis of the Shoulder Dystocia and the time of delivery of the shoulders of the baby. The medical literature states that an Obstetrician has in excess of five to six minutes before he should begin to worry about permanent brain damage.

Defense experts will testify that Obstetrician's have only three to four minutes before fetal brain damage occurs. Thus, the "emergent situation" defense is feed by defense expert witnesses creating the theory that Obstetricians must act in a very aggressive manner almost immediately subsequent to the differential diagnosis to avoid fetal brain damage. Note that idea that there is only three to four minutes in which to manage a Shoulder Dystocia is not supported by relevant medical literature. Defense experts who are willing to make this statement will base it upon their "training and personnel experience," not the medical literature.

Also, be aware that the "emergent situation" defense will be further served by plaintiff medical expert witnesses' testimony if you are not careful. If you have your Obstetrical expert explain to the jury how techniques for management of Shoulder Dystocia are performed you will be assisting the defense. As your expert explains the Obstetrical maneuvers used in the management of a Shoulder Dystocia, maneuvers which require only seconds to perform on a patient it will take your expert several minutes or more to explain to a jury. Jurors will be tempted to add up the time it takes an expert to explain these maneuvers and wrongly conclude that an Obstetrician faced with a Shoulder Dystocia only has time to perform one or two maneuvers before placing the baby at serious risk of brain damage. If you fail to ask your expert witness how long it takes to perform each maneuver, jurors will be mislead to believe that maneuvers which take thirty seconds to perform require two or three minutes. The "emergent situation" defense capitalizes on this error.

Therefore, expect defense attorneys to emphasize that the defendant physician was facing an emergent situation, an emergency where he had only 120 to 180 seconds in which to cope with the emergency. The consequences of his failure to get the baby out in 120 seconds from the moment of diagnosis of Shoulder Dystocia is a brain damaged infant. By making this argument, defense attorneys "justify" their clients use of excessive lateral traction because the jury has been left believing that there was not sufficient time for the Obstetrician to get the baby out without using excessive lateral traction.

Countering the "Emergent Situation" Defense

Countering the emergent situation defense is a complicated task for it involves (1) impeaching the defense OB/GYN expert as to the time available to manage a Shoulder Dystocia, (2) presenting credible evidence that there is at least five minutes to manage the dystocia before Obstetrician's should be concerned with fetal brain damage, (3) showing the alternate maneuvers available to the defendant Obstetricians to relieve the Shoulder Dystocia other then excessive downward or upward lateral traction, and (4) demonstrating that the Erb's Palsy was not an "act of God" and was not caused by a fetal mal adaptations or mal formation.

Do the following: (a) bring a large clock and let the court sit in silence for five minutes. This act will demonstrate to the jury that five minutes is a very long time and will serve to counter the defense argument that Shoulder Dystocia is an emergency requiring an "immediate aggressive response." (b) Have the defense experts and the defendant physician state exactly how long it takes to perform each maneuver used to manage a Shoulder Dystocia. For example, Woods Corkscrew takes thirty seconds, an episiotomy takes fifteen seconds. Then prepare a time lines using each physicians testimony and the medical records to show how the precious minutes between diagnosis and delivery were spent. It has been our experience at E.T.I. that the defendant doctors almost always have time in which to repeat maneuvers. The time line will suggest to a jury that the Obstetrician failed to properly exhaust all maneuvers available to assist the delivery and in a panic needlessly applied excessive lateral traction injuring the fetus. [It is noteworthy that fetal cord blood gases, if taken, are indicative of the degree of fetal oxygen deprivation. Failure to test fetal cord blood gas levels during delivery could be indicative that the attending Obstetrician was not concerned with fetal brain damage during the delivery.] (c) Remove the determination of how much time a fetus can go without oxygen before the onset of brain damage from the OB/GYN experts. Hire a neonatologist or maternal fetal medicine expert who has published studies regarding the amount of time fetal brain tissue can survive without oxygen. Have this expert witness utilize the medical literature which supports the position that you have at least five minutes to manage Shoulder Dystocia. (d) Ask the defense experts at deposition how many cases of permanent Shoulder Dystocia/Erb's Palsy that expert has personally managed. Go into detail as to the management performed during those deliveries. Specifically, ask him if he has ever had a baby suffer from permanent brain damage while in the care which he believes was caused by less then aggressive management of a Shoulder Dystocia. Pursuit of this line of questioning should serve to assist in preventing defense experts from stating at time of trial that there "experience" has been that there is only a three or four minute window in which to deliver the baby. Also, prepare exhibits to illustrate this information.

Other Issues in Birth Related Brachial Plexus Injuries Cases


APGAR Scores

An APGAR score is a method of comparing the health of the baby as against other babies. APGAR scores are taken at one minute and five minutes; the highest possible score being a ten, the lowest a zero. In support of the "Emergent Situation" defense, defense counsel may point to low one minute APGAR scores and blatantly state to the jury that this baby was practically dead at the time of delivery. This is at best a distortion of the truth and at worst an outright lie.

One minute APGAR scores within themselves are non-conclusive because they can be influenced by several factors. (a) It is possible that a low one minute APGAR score is merely associated with the normal traumas that accompany a vaginal birth. This trauma is significant as it turns every baby's skin blue. (b) Low one minute APGAR scores coupled with low five minute APGAR scores are much more suggestive of exhaustion of fetal reserves and are an indication that the infants brain may be damaged. Low one minute APGAR scores coupled with high five minute APGAR scores signify that the fetal reserves were strong at the time of delivery and indicate that the fetus recovered very quickly from the trauma associated with birth. Low one minute and high five minute APGAR scores are not indicative of a near dead baby and are not suggestive that brain damage by asphyxiation was likely to occur. (c) It is also probable that the baby's throat was being suctioned at the time the one minute APGAR score is taken or was suctioned immediately prior to the taking of the one minute APGAR score. Baby's throats and noses are routinely suctioned to ensure that the air passages are free from amniotic fluid and meconium. Suctioning involves putting a large tube in the mouth and throat of the newborn and causes the baby to gag. In cases where meconium is present, suctioning will be more thorough to ensure that meconium doesn't get into the baby's lungs. The trauma associated with suctioning can turn a healthy baby blue and cause a reduced rate of respiration for several minutes after the procedure has been completed. Suctioning, thereby, can cause an artificially low APGAR score.

Nuchal Cords

It is very possible that the defense will try to confuse the jury by pointing out that the defendant had to deal with a Nucal Cord. A Nucal cord is the term used to describe an umbilical cord rapped around the baby's neck when the head is delivered. The defense might try to allege that a Nucal Cord further complicated the delivery and assisted in depletion of the fetal reserves. This argument is without substance or merit.

According to Williams' Obstetrics, 25% of all births involve a Nucal cord. It is a simple and well rehearsed practice for the physician to deal with Nucal Cord situations; the physician either slips the cord over the baby's head thereby freeing the neck or if the cord is to tight to pull over the baby's head, clamps and cuts the cord. The entire process takes less then twenty seconds from diagnosis to remedy.

It is noteworthy that the fetus probably does not receive oxygen from the umbilical cord once the head has been delivered, so cutting the cord at the time of differential diagnosis of Shoulder Dystocia does nothing to change the amount of time available to the Obstetrician to deliver the baby.

Utilizing the Relevant Medical Literature Governing Erb's Palsy

Medical literature is composed of textbooks, such a Williams', Obstetrics, medical articles and ACOG Technical Bulletins. [ACOG, the American College of Obstetrics and Gynecology, is a private national organization composed of Obstetricians/Gynecologists. The organization produces several publication including Technical Bulletins. The Technical Bulletins are the product of a committee. As such, the Technical Bulletins are not subject to "peer review" (discussed, infra.) and occasionally contain self-serving information. However, as a rule, Technical Bulletins express the applicable standard of care. But, when the Technical Bulletins digress into the medical equivalent of Dicta, those portions of the Technical Bulletin should be attacked if relied upon by medical expert witnesses.] Textbooks are used for reference and teaching by physicians. Certain medical textbooks, like certain legal textbooks, are considered to be more authoritative. Williams', Obstetrics is the seminal work in Obstetrics. It states the applicable standard of care.

Medical articles, unlike Williams' Obstetrics, are subject to interpretation by physicians. The rough legal equivalent of medical articles are law review articles. The significance of a medical article depends upon (a) the journal the article was published, (b) its authors, (c) the number of cases similar to yours that were part of the study encapsulated by the article, and (d) whether the article was truly subject to "peer review" prior to publication.

"Peer Review" is the process where the editors of any given medical publication send the article and it's supporting data to be reviewed and substantiated by a panel of physicians who are unknown to the authors of the article. Before publication, the panel of reviewers analyze the submitted material and verify its conclusions. Peer review serves to ensure that the articles published in medical journals are of the highest scientific value. Unfortunately, not all articles published in medical journals are subject to "peer review."

Publication without peer review most commonly occurs when the authors of a paper are invited to speak at a conference sponsored by a journal and orally present a paper. The paper is subsequently published by the journal as an article without the article and supporting material being reviewed by independent physicians. These articles are of questionable scientific value and are often published to protect the medical establishment from malpractice lawsuits. The Jennett Article "Brachial plexus palsy: an old problem revisited" published in the June, 1992 issue of The American Journal of Obstetrics & Gynecology is the quintessential example of a medical article being published without it being subject to the peer review process. Am J Obstet Gynecol 1992: 1673-7.

The Jennett article is based on a study which concluded that

... intrauterine mal adaptation may play a role in brachial plexus impairment. Brachial plexus impairment should not be taken as prima facie evidence of the birth process. [Jennett article, preface at p. 1673.]


On the surface, the Jennett article appears to be very damaging to plaintiffs. It is interesting that in the Comment section of this article, Dr. Philip E. Young notes that the promulgation of this article "would be a big help to practicing obstetricians." It is clear that the panel of physicians asked to comment on this article were more interested in how the study could assist their colleagues in the defense of Shoulder Dystocia related malpractice lawsuits rather then a careful review and evaluation of the data to determine if it supports the conclusions put forward by Dr. Jennett and his colleagues. For a complete analysis of this article please refer to the attached materials.


Conclusion

It is my opinion that it is possible to win birth related brachial plexus injury cases even though they are complex so long as the legal issues are properly narrowed during discovery and the jury is properly educated during trial. If E.T.I. or I can be of further assistance to you in presenting your case, please do not hesitate to contact us.
