Submitted: February 27, 2026 Decided: March 4, 2026
The Court must determine whether a treating podiatrist is permitted to testify
regarding the reasonableness, cost, and necessity of a spinal cord stimulator where
treatment notes indicate Plaintiff was referred to undergo a lumbar MRI and
consult an orthopedic spine surgeon to discuss the procedure. The Court has
reviewed the parties’ arguments, the record, and the law governing this matter. The
Court finds the testimony will be limited, in part.
Factual Background
Plaintiff seeks uninsured motorist benefits from Defendant. Factually, she
maintains an uninsured motorist ran over her foot and she suffered injury as a
result.1 Defendant disputes the facts underlying the incident, as well as the “nature
1 Pretrial Stipulation, at p. 1. and extent, and/or causal relationship” of the injuries.2 Plaintiff treated with Dr.
Jamrok, a podiatrist. For over a decade, Dr. Jamrok has practiced with Peninsula
Orthopaedic Associates. He is a member of the American Podiatric Medical
Association and the American Board of Orthopaedics and Primary Podiatric
Medicine.3
Dr. Jamrok has not been deposed; however, he authored a two-page report,
detailing his treatment of Plaintiff. He diagnosed Plaintiff with RSD/complex
regional pain syndrome 1 and his report details she was treated with physical
therapy and medication for pain, inflammation, and “her nerve situation.”4
Eventually, Dr. Jamrok felt Plaintiff was “no longer significantly improving…”5
The record as to Dr. Jamrok’s treatment, general qualifications, and qualifications
specific to the spinal cord stimulator is limited to his report and CV. The Court has
been provided with portions of Plaintiff’s deposition transcript and one additional
treatment note from a physician assistant within Dr. Jamrok’s practice.
Significant for this decision, Dr. Jamrok’s report states he “recommended
that the patient visit my partner Dr. McGovern to discuss the DRG spinal cord
stimulator which is indicated for RSD/complex regional pain syndrome.”6 Dr.
2 Id. at p. 2. 3 See Plaintiff’s Response in Opposition to Defendant’s Daubert Motion to Exclude and/or limit the testimony of Plaintiff’s Medical Expert (“Plaintiff’s Response”), Exhibit B. 4 Id. at Exhibit A at p. 1. 5 Id. at p. 2. 6 Id. Jamrok further stated “I believe that the prognosis for the patient with the DRG
spinal cord stimulator would be very positive.”7 Thus, it appears the stimulator
requires surgery which Dr. Jamrok could not perform. The report of Dr. Jamrok
and his expert disclosure does not detail his experience managing patients who
have had a spinal cord stimulator.
Dr. Jamrok does not opine as to the cost of the device or its implantation.
He concludes his report “the patient is going to need more advanced treatments
such as the DRG spinal cord stimulator to completely resolve her RSD/complex
regional pain syndrome 1 based on her last visit.”8
Defendant points, in part, to a medical record from Trevor Abbott, a
physician assistant within Dr. Jamrok’s practice, that is dated more than six months
before Dr. Jamrok’s report. Mr. Abbott’s note states “[n]ext appointment will be
with Dr. McGovern. I have ordered a lumbar MRI9 and will have the patient
follow-up with Dr. McGovern to discuss if she is a candidate for DRG
neuromodulation.”10
Plaintiff testified she met with Dr. McGovern and discussed the spine
stimulator. This transcript includes her description of the stimulator— “it was

button that I would push if I had pain.”11 Plaintiff was not interested in pursuing
this option.
Parties’ Contentions
Defendant argues Dr. Jamrok’s opinions regarding the spinal cord stimulator
should be excluded by this Court, under its gatekeeping function, because his
opinions are “speculative, unreliable, and exceed the scope of his qualifications as
a podiatrist.”12 Defendants argue testimony on this point “requir[es] specialized
spinal and neurosurgical expertise.”13 To put a finer point on the issue, Defendant
argues “[w]hether a patient is a candidate for a DRG spinal cord stimulator—a
surgically implanted spinal device—falls well outside the scope of podiatric
medicine.”14
Moreover, Defendant suggests such testimony would be speculative because
Plaintiff did not follow-up on recommended diagnostic studies to evaluate for the
spinal cord stimulator. In Defendant’s view, whether she is a candidate for the
spine stimulator is a decision made by Dr. McGovern. Therefore, Defendant asks
the Court to exclude or limit the testimony of Dr. Jamrok on the subject of the
11 Plaintiff’s Response, Ex. C. at p. 23. 12 Defendant’s Daubert Motion to Exclude and/or Limit the Testimony of Plaintiff’s Medical Expert at ¶ 2. 13 Id. 14 Id. at ¶ 4. spine stimulator. Defendant also asked the Court to preclude opinion testimony
from Dr. Jamrok regarding the RSD/complex regional pain syndrome 1 diagnosis,
but this portion of the motion was withdrawn during oral argument.
Plaintiff disputes these characterizations. Plaintiff points to Dr. Jamrok’s CV
and argues he has “specialized expertise in foot and ankle pathology.” Plaintiff
frames the question slightly differently insofar as she advises Dr. Jamrok is not
offered to testify as to how to perform the implementation but instead will testify
she will not improve without it. Plaintiff answers the charge of speculative
testimony by pointing to two years of treatment and an MRI. Plaintiff suggests her
doctor can testify as to his recommendation for the spine stimulator even if she did
not undergo diagnostic testing, which she characterizes as ordered “to finalize
surgical placement.”15

in a particular case, the issue is such that the jurors are not competent to draw their
own conclusions from the facts without the aid of the expert.”19 In making this
determination, the Court looks to D.R.E. 702 and to Daubert.20
Delaware Rule of Evidence 702 provides:
A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if: (a) The expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) The testimony is based on sufficient facts or data;
(c) The testimony is the product of reliable principles and methods; and
(d) The expert has reliably applied the principles and methods to the facts of the case. This Court must be focused on principles and methodology, not the conclusions
of the expert—and while the Court’s inquiry is guided by factors, they are flexible.21
The factors include: 22
18 In re Zantac (Ranitidine) Litigation, 342 A.3d at 1144 quoting Tumlinson v. Advanced Micro Devices, Inc., 106 A.3d 983, 990 (Del. 2013). 19 Minner v. Am. Mortg. & Guar. Co., 791 A.2d 826, 846 (Del. Super. Ct. 2000) (citation omitted). 20 D.R.E. 702; Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993). 21 Daubert, 509 U.S. at 594. 22 Most recently in In re Zantac (Ranitidine) Litigation, 342 A.3d at 1144 quoting Daubert, 509 U.S. at 593–94. (1) Whether the expert opinion testimony “can be (and has been) tested”
(2) Whether the opinion testimony “has been subjected to peer review and
publication”
(3) The “known or potential rate of error” and
(4) Whether it has attracted widespread acceptance within the scientific
community.
The Delaware Supreme Court has recently reaffirmed this Court’s obligation as
a gatekeeper and that this Court should not presume admissibility.23 As to relevance,
the proffered expert testimony must both “relate to an ‘issue in the case’ and ‘assist
the trier of fact to understand the evidence or to determine a fact issue.’”24 “Courts
are not just to let the opinion of the credentialed expert into evidence for what it is
worth and leave its evaluation to the jury.”25 While the Court should consider the
expert’s background
[t]he words of an expert qualified to opine within a recognized “field” do not automatically guarantee reliable, and therefore admissible, testimony, however. The inquiry will be whether the expert and the “field of expertise” itself can produce an opinion that is sufficiently informed, testable and in fact verifiable on an issue to be determined at trial.26
23 Id. at 1147. 24 Tumlinson v. Advanced Micro Devices, Inc., 81 A.3d 1264, 1269 (Del. 2013) (internal footnote omitted) quoting Daubert, 509 U.S. at 591. 25 Minner v. Am. Mortg. & Guar. Co., 791 A.2d 826, 841 (Del. 2000). 26 Eskin v. Carden, 842 A.2d 1222, 1228 (Del. 2004). In O’Riley v. Rogers, the Delaware Supreme Court set parameters for this
Court to consider.27 Specifically, “[a] doctor cannot base his expert medical opinion
on speculation or conjecture.”28 Indeed, “a doctor’s testimony that a certain thing
is possible is no evidence at all.”29 In O’Riley, Plaintiff treated with an orthopedic
surgeon but did not undergo a recommended diagnostic test to determine the source
of the injury due to cost concerns. At trial, on cross-examination, testimony was
elicited that, if the diagnostic test were completed, it would enable the doctor to
determine if surgery were appropriate.30 Upon review, it was determined that the
proper bounds of expert testimony were exceeded when “counsel asked the doctor
to speculate about the possible medical consequences of possible treatment courses
an EMG test might reveal.”31
In Li v. Geico, this Court excluded testimony from an expert regarding the
potential need for future surgery.32 In its decision, this Court noted conclusions
within the expert’s report were phrased in a speculative manner. The Court found
the proffered testimony sought to “opine about the possible courses of treatment and
costs that might arise if now-unmet conditions are satisfied in the future.”33
27 69 A.3d 1007 (Del. 2013). 28 Id. at 1011 quoting Oxendine v. State, 527 A.2d 870, 873 (Del. 1987). 29 Id. 30 Id. at 1009. 31 Id. at 1012. 32 2019 WL 4928614 at *2 (Del. Super. 2019). 33 Id. at *2. “An expert may be highly qualified and competent to offer many opinions.
But that expert must be competent to offer opinions in a given specific factual
setting.”34 This Court has also excluded speculative expert testimony from a doctor
couched in terms of the “likely” form of surgery “if” treatment was ineffective and
that he was “hopeful” total knee replacement was not required. 35
Analysis On the record presented, the mechanics of the DRG spinal cord stimulator
surgery is limited to Plaintiff’s lay testimony. What a DRG spinal cord stimulator
is or does, or which doctor/specialty determines its proper use and/or management
is unclear. Further, while Plaintiff argues the diagnostic testing ordered is for the
purpose of determining surgical placement as opposed to determining the necessity
or reasonableness of surgery—the Court can find no record citation for this
proposition.36
Plaintiff cites Pavey v. Kalish for support.37 Specifically that it is the Court’s
duty “not to determine which theory is stronger but instead to act as a gatekeeper
who determines whether the testimony is based on sufficient facts or data and on
reliable principles and methods that have been reliably applied to this case.”38
34 Friedel v. Osunkoya, 994 A.2d 746, 751 (Del. Super. 2010). 35 Jackson v. Aglio, 2014 WL 1760316 *3 (Del. Super. 2014). 36 See Plaintiff’s Response at ¶ 8. 37 3 A.3d 1098 (Del. 2010). 38 Id. at *3. Here, the Court is not presented with alternate theories; instead, the Court is asked
if the testimony is based on sufficient facts or data.
With the legal principles cited above in mind, the Court re-reviews the report
of Dr. Jamrok and his expert disclosure. His report indicates he recommended
Plaintiff “visit my partner Dr. McGovern to discuss the DRG spinal cord stimulator
which is indicated for RSD/complex regional pain syndrome.” Dr. Jamrok notes
Plaintiff will need “advanced treatments such as the DRG spinal cord stimulator”
Additionally, the note from Mr. Abbott indicates he ordered a lumbar MRI and
advised Plaintiff follow-up with Dr. McGovern to discuss if she is a candidate for
DRG neuromodulation.” The Court finds this language is line with testimony
excluded in both O’Riley and Li because it is speculative.
Dr. Jamrok can testify as to his diagnosis of RSD/complex regional pain
syndrome 1. He can testify regarding his treatment of Plaintiff. He can testify that
she has not significantly improved with the course of treatment he prescribed.
However, Dr. Jamrok cannot testify as to the cost of the DRG spinal cord
stimulator, as he candidly states he does not have that information. The record
does not have sufficient information to evaluate the quality of testimony proposed
as it relates to the DRG spinal cord stimulator. Nor does the Court have sufficient
information, under a preponderance of the evidence standard, regarding the field of expertise applicable to evaluating Plaintiff’s suitability for the spinal cord
stimulator or its management.
Regarding the reasonableness of the DRG spinal cord stimulator, the Court
finds the referral to Dr. McGovern, without any clarification of Dr. McGovern’s
role in the matter, leaves a record that is unclear as to the underlying basis of such
reasonableness under Rule 702. It is unknown if Dr. McGovern was identified to
simply carry out the procedure after Dr. Jamrok determined it was appropriate, or if
Dr. McGovern would be required to independently assess Plaintiff in determining
whether she is an appropriate candidate for a DRG spinal cord stimulator. The
record reflects an MRI was ordered at the time the referral to Dr. McGovern was
made. While Plaintiff asserts the purpose of the MRI was to limited assist with
surgical placement and not for diagnostic purposes, the Court cannot make this
factual connection in the record. It appears no such MRI has been completed.
Therefore, the Court determines it would be impermissibly speculative to permit
testimony regarding the spinal cord simulator.
Finally, Dr. Jamrok concludes Plaintiff’s prognosis with a spinal cord
stimulator is “very positive.” However, the underlying support for this conclusion
is also unknown. The Court finds this does not meet the standard under 702.
The Defendant’s Motion to Exclude and/or Limit Testimony is therefore,
GRANTED, in part. IT IS SO ORDERED.
