Defense Verdict Received Medical Malpractice Arbitration Matter

Health Care Liability
April 7, 2025

We received a defense verdict at the Montgomery County Arbitration Center where the three-attorney panel found in favor of our clients, a pediatric primary care office and a pediatric nurse. We represented the pediatric practice and the nurse against claims from the plaintiff who claimed her median nerve was injured by a venipuncture procedure performed by the nurse. The case was originally filed in the Court of Common Pleas; however, after discovery revealed a weak damages claim-we found many TikTok videos helpful to our defense-it was dropped to the arbitration level.

Health Care Liability
October 16, 2024

After an eight-day trial, we secured a directed verdict on behalf of his client, an orthopedic surgeon, who allegedly breached the standard of care as it relates to his performance of a reverse right shoulder replacement. The court found that the plaintiff failed to establish that the surgery performed by the orthopedic surgeon was unnecessary, as alleged.

Health Care Liability
March 16, 2023

The plaintiff filed a medical malpractice case, claiming the emergency room physician failed to appropriately treat her elevated blood sugar and groin abscess, leading to necrotizing fasciitis. The evidence presented to the jury supported the argument that the emergency room physician appropriately treated the small spontaneously draining groin abscess as presented, there were no signs of systemic infection, and the physician gave appropriate instructions for the plaintiff to return to the hospital if her symptoms changed or worsened.

Partial summary judgment for obstetrician and health system in birth injury case.

Birth & Catastrophic Injury Litigation
August 13, 2021

We secured partial summary judgment for a Central Pennsylvania obstetrician and health system in a birth injury case that also alleged significant urogynecological injuries to the mother. The plaintiff’s firm had previously secured a $10 million award for a similar maternal claim. In this matter the court agreed that the plaintiff’s expert reports were insufficient, and dismissed the corporate negligence claim, the claim for injuries and future economic and non-economic damages of the child, and the mother’s claim for future economic and non-economic damages.

Defense Verdict for a Pennsylvania Health System and Urologist.

Health Care Liability
December 31, 2018

We received a defense verdict on no causation in a binding arbitration of a matter venued in Montour County, Pennsylvania, involving a bowel leak following urologic cancer surgery. We represented a Pennsylvania health system and its chief of urology who performed major cancer surgery upon the plaintiff (cystoprostatectomy and creation of ileal conduit).
