COOCH, R.J.

This 10th day of May 2018, upon consideration of Defendants’ Motion
in Limine to Limit the Testimony of Scott Kozin, M.D., it appears to the Court
that:

l. This case involves Plaintiffs’ medical negligence claim against
Defendants arising out of a vaginal delivery of` minor Plaintif`f,
Tyra Curtis, in Which she suffered What Plaintiffs allege Was a
permanent brachial pleXus nerve injury. Plaintiff`s claim that the
delivering physician, Defendant Diane McCracken, M.D.,
applied excessive traction to deliver Tyra, Which caused the

inj ury.

2. Defendants filed a motion in limine to limit the testimony of`
Plaintiff” s causation expert, Scott Kozin, M.D. (“Dr. Kozin”), on
January lO, 2018. Defendants seek to limit Dr. Kozin’s
testimony in three Ways. First, Defendants request that Dr.
Kozin’s testimony be restricted to certain opinions at his
deposition and the first trial.' Second, Defendants “request [that
Dr. Kozin] be precluded from offering any opinions that
[Plaintiff"s] brachial plexus injury is ‘consistent With’ excessive
downward lateral traction applied by the clinician” as,
Defendants claim, those types of comments improperly infer
opinions that Defendants breached the standard of care. 2 Third,
Defendants ask that Dr. Kozin be “precluded from discussing the
Lerner article at trial.”3 Defendants’ argument essentially is that
because Dr. Kozin “did not have a specific causation opinion
beyond What Was outlined herein at the time of his deposition . .
. [h]e should therefore be precluded from offering opinions
beyond What Was initially testified to.”4

 

l During an office conference before the Court on November 6, 2017, counsel for Defendants
presented the scope of` testimony Within Which Dr. Kozin should be contained for this third try of
the case. Def.s’ Mot. in Limine, Ex. l at 15-18.

In response, Plaintiffs argue that Dr. Kozin indeed had a
causation opinion prior to the second trial on October 31, 2017
and that Dr. Kozin’s deposition testimony shows that he was not
giving a standard of care opinion.5 Also, Plaintiffs assert that Dr.
Kozin’s comments about the Lerner article at the second trial
were not new opinions because Dr. Kozin “referred to it in his

deposition . . . .”6

A third trial will be held in this case. The first trial resulted in a
mistrial due to a hung jury. The Court declared a mistrial in the
second trial due to Dr. Kozin’s trial testimony, which differed
from his deposition and first trial testimony and contained new
opinions Now Defendants seek to define the scope for Dr.
Kozin’s testimony that is consistent with both his May 26, 2016
deposition testimony and his October 31, 2017 second trial
testimony. As this Court stated in granting Defendants’ motion
for a mistrial during the second trial, Dr. Kozin offered a new
opinion in the second trial as to causation contrary to his
deposition testimony and to his testimony during the first trial.7
His previous deposition and trial testimony was that essentially
that he could not offer an opinion whether maternal forces alone
were enough to cause permanent brachial plexus injury.
However, during the second trial, his testimony was that he could
now exclude endogenous or maternal forces as a cause of
permanent brachial plexus injury. This Court agrees with the
parameters offered by Defendants at the November 6, 2017
office conference as to the allowable scope of his testimony and
grants the motion in limine.

Dr. Kozin’s testimony at the third trial will be limited to
testimony that he provided at his deposition and to the testimony
he gave at the first trial (and to which defense counsel did not

object).

“Under 18 Del. C. § 6853, a party alleging medical malpractice
must produce expert medical testimony that specifies (1) the

61d. at 5.

applicable standard of care, (2) the alleged deviation from that
standard, and (3) the causal link between the deviation and the
alleged injury.”8 In general, experts must qualify under
Daubert’s five-step test to determine the admissibility of the
expert testimony.9 The Court must determine whether:

(1) the witness is qualified as an expert by knowledge, skill
experience, training or education; (2) the evidence is relevant;
(3) the expert's opinion is based upon information reasonably
relied upon by experts in the particular field; (4)
the expert testimony will assist the trier of fact to understand the
evidence or to determine a fact in issue; and (5)
the expert testimony will not create unfair prejudice or confuse
or mislead the jury.l°

7. The Delaware Supreme Court has held “that the requirement of a party
to comply with discovery directed to identification of expert witnesses
and disclosure of the substance of their expected opinion is a pre-
condition to the admissibility of expert testimony at trial.”" An
expert’s trial testimony must be consistent with their expert
disclosure.12

8. Dr. Kozin’s expert disclosure, pursuant to Del. Super. Ct. Civ. R.
26(b)(4), provided that “[b]ased upon his expertise, knowledge, clinical
experience and his best medical judgment, Dr. Kozin will opine to the
causation and damages issues of this case.”13 Plaintiffs did not identify
Dr. Kozin as an expert who would be giving a standard of care opinion

12 See, e.g., Barrow v. Abramowicz, 931 A.2d 424, 434 (Del. 2007)

The trial judge abused his discretion by permitting Dr.
Abramowicz' testimony because the defense never identified Abramowicz as
an expert who would be giving causation opinions at trial. . . . The significance of
Dr. Abramowicz's noncompliance is enhanced because his pretrial testimony on
the underlying causation issue contradicted his trial testimony.

at trial. As Defendants argue, Dr. Kozin is precluded from offering an
opinion that the injury in this case is “consistent with” excessive
physician-applied downward lateral traction because that type of
opinion carries the risk of improperly inferring to the jury that this
injury was caused by a breach in the standard of care by the physician.14
Accordingly, any proffered opinion by Dr. Kozin regarding standard of
care at the third trial will be prohibited.

9. At his May 26, 2016 deposition, on the topic of physician-applied
force, Dr. Kozin stated

A: Yeah, l think the OB-GYNS will have to fight about
that. What l said before is I can’t tell you, in Tyra’s case or any
other child’s case, whether the force applied . . . was excessive
to deliver Tyra. I can just tell you the force was excessive to
maintain the integrity of the nerves, which led to the tearing of 5,
6, and 7.

Q: And forces are - can be multiple in nature, correct?

A: They can be endogenous or exogenous. Exogenous
being the deliverer, and endogenous meaning the propulsive
forces.15

At a later point in Dr. Kozin’s deposition testimony, Mr. Batten
again on cross-examination asked Dr. Kozin to address the
“force” issue.

Q: And excessive is a bit of a loaded word, and here’s
why I’m going to suggest that to you. Excessive, in your
vemacular, is, it was more than that nerve could take, not that
there was a breach of a standard that caused excessive force,
correct?

A: Right. So it’s my opinion, regardless of what the jury
decides was the ultimate cause, there was excessive force to the
nerve. l thought what Mr. Hudson was asking me was, if
excessive, meaning excessive - I don’t know what he was asking
me the more l think about it. But so l think - my opinion is
going to be, there was excessive force to the nerves, period.
That’s a given. I’m not going to say there wasn’t, because there
was tearing of 5, 6, and 7.

Q: And force does not imply solely the clinician’s
applied traction, correct?
A: No, no. There are multiple forces.l

6

However, during the second trial, Dr. Kozin testified, “[i]t’s my
opinion that [the injury] occurred from the traction applied to the
head, which led to the stretching of the nerves in her neck.”17
This opinion was new and different from the causation opinion
he gave during his deposition above, where he had equivocated
to some extent on the specific cause,

10. Furthermore, as to the Lerner article,18 Dr. Kozin may not
provide an opinion on it, or the related video, at the third trial. At
the second trial, during direct examination, Dr. Kozin relied on
the Lerner article for his new opinion, which essentially excluded
endogenous forces as a possibility in this case. Dr. Kozin’s
deposition testimony and his second trial testimony differed from
his trial testimony in the first trial as it related to the Lerner
article. At his deposition, when asked by counsel for Defendants,
Mr. Batten, Dr. Kozin testified as follows:

Q: And so l’m clear, can the maternal propulsive forces
alone of pushing the baby down the birth canal be enough to
cause a permanent injury without any physician intervention?

A: I think that’s unclear.

Q: Okay. The answer is you don’t know?

A: l don’t know.

Q: Can you see any report of a permanent injury
occurring in the absence of shoulder dystocia, case report out
there? Do you know what l’m talking about?

A: Lemer.

Q: Yeah. Have you seen that video?

A: lthink it’s L-E-R-N-E-R, right?

Q: lt is. Have you seen the video?

A: l don’t recall seeing the video.

https://www.mdedge.com/sites/default/files/Document/September-2017/OBG_0914_Lerner.pdf,

describes a case where a neonatal brachial plexus palsy injury occurred in a delivery where there
was no traction applied by the delivering physician. Pl.s’ Resp. to the Mot. in Limine at 6, n.l.

Q: All right. Have you read his report?

A: Awhile back, yes.

Q: Okay.

A: And there’s some rebuttal afterwards and another

heated argument.
Q: Do you dispute the existence of what he reported?
A: l don’t dispute what was reported. I know it’s been
attempted to be disputed, but it has not been retracted.19

The above testimony differed from Dr. Kozin’s testimony on
direct examination by counsel for the Plaintiffs, Mr. Hudson, at
the second trial. At his deposition, Dr. Kozin had given a brief,
cursory acknowledgement of the existence of the Lerner report,Z°
but at trial he discredited the report’s findings:

Q: Are you aware of any credible medical study
reporting that a permanent brachial plexus injury during a
delivery can occur, or has occurred in the absence of traction in

a shoulder dystocia case?
A: No, l’m not.

Q: And tell us do you consider [the Lerner case report] a

credible report?
A: I do not. Most of that report has been discredited by
either deposition testimony or review of the records from the

CHSC.

Q: ln the summary here it says that the delivery resulted
in a permanent brachial plexus injury unassociated with shoulder
dystocia or physician traction. And it is being reported by the
delivering physician. This case demonstrates unequivocally that
not all permanent brachial plexus injury at vaginal birth is due
to physical traction. ls this a correct statement of the facts of this
case report?

A: That’s inconsistent with subsequent reports.21

Dr. Kozin’s opinion at the second trial that the Lerner study,
which appears to state that this injury may occur without
physician or exogenous forces, was not “credible” and was

 

19 Def.s’ Mot. in Limine, Ex. 2 at 90-91.
20 Dr. Kozin only referenced the Lerner article in his deposition when asked about it by Mr. Batten
on cross examination Dr. Kozin had not not mentioned it on direct examination. See generally id.
21 Def.s’ Mot. in Limine, Ex. 3 at 65-67.

“inconsistent with subsequent reports” is a significant departure
from his deposition testimony where he stated that he did not
“dispute what was reported” in the Lerner study. ln contrast, and
during his deposition, Dr. Kozin had stated that the excessive
force applied on the nerves “can be endogenous or exogenous
[where] [e]xogenous [means] the deliverer, and endogenous
mean[s] the propulsive forces.”22 By testifying at trial that, in his
medical expertise, the Lerner study deserves no worthy
consideration, Dr. Kozin, in effect, ruled out endogenous forces
as a causative factor in this injury.

1 1. Dr. Kozin will be precluded from discussing the video associated
with the Lerner study as well. Dr. Kozin testified at his
deposition that he had not seen it.23 However, during the second
trial, Dr. Kozin stated that he had indeed watched that video
(which had been sent to him “a couple weeks” before the second
trial “from a plaintiffs lawyer [in New Jersey] in a medical
negligence case” unrelated to this case).24

Q: Dr. Kozin, in terms of your personal knowledge of the
circumstances involved in this delivery, which represented that
it was permanent injury but no traction and no shoulder dystocia,
have you seen a video that was taken during the delivery by one
of the family members?

A: l recently saw the video, yes.

Q: Does the video show whether traction or not was
used‘? The article says it was no traction, what does the video
show?

A: l can’t see anything in the video with reference to
whether traction was applied or not.

Q: You’ve watched the video?

A: I just recently was able to obtain the video.

Q: And the video - it is inconclusive because of the view
being blocked as to whether the physician applied traction‘?25

 

22 Def.s’ Mot. in Limine, Ex. 2 at 71-72. Dr. Kozin describes “propulsive forces” as “maternal
propulsive forces . . . if they’re really pushing, that can lead to increase push on the baby as they
come down the canal.” Ia'. at 72.

23 Id. at 91 (“Q: lt is. Have you seen the video? A: l don’t recall seeing the video.”).

24 Def.s’ Mot. in Limine, Ex. 3 at 82- 91.

25 Def.s’ Mot. in Limine, Ex. 3 at 71-72.

12. As an expert, Dr. Kozin may not expand the scope of his original
deposition and first trial opinions to these bounds. His second
trial testimony was not only different from his previous
deposition testimony, but was contrary to it. Also, as stated on
his expert disclosure, Dr. Kozin’s role in this case is as a
causation expert. As such, he may not offer any opinion as to the
standard of care in this case. Dr. Kozin’s testimony must coincide
with his deposition testimony. Accordingly, Defendants’ Motion
in Limine to Limit the Testimony of Scott Kozin, M.D. is
GRANTED.

13. As the Court has advised counsel, the Pretrial Stipulation must
state, in detail, the substance of what Dr. Kozin may testify to,
and what he may not testify to, in order to further ensure that the
problems with his testimony in the second trial do not occur in
the third trial.

IT IS SO ORDERED.
