The Pennsylvania Superior Court has upheld a jury's verdict in the case of Musika v. Gopez, affirming that Dr. Jonas J. Gopez was not negligent in a medical malpractice claim regarding the treatment of John Musika's chordoma, a rare spinal tumor. The court's decision, filed on June 22, 2026, is significant for the Musika family, who alleged that medical professionals failed to properly diagnose and treat John's condition, leading to further complications.

John and Linda Musika filed their appeal after a jury found that while Dr. Gopez was not negligent, another physician, Dr. Stephen Pripstein, was found to have breached the standard of care in interpreting an MRI that led to a delay in diagnosis. The jury awarded the Musikas $1 million for damages related to Dr. Pripstein's negligence but ruled in favor of Dr. Gopez, stating that he did not act below the standard of care during the treatment process.

This case began when John Musika experienced chronic back pain and sought medical attention. An MRI performed in 2011 was interpreted by Dr. Pripstein, who allegedly missed a mass on John's spine. After persistent symptoms, a second MRI in 2013 revealed the mass, but Dr. Fabrizzio, who interpreted this MRI, did not diagnose it as a chordoma. John was referred to Dr. Gopez, who performed surgery but did not confirm the diagnosis with a biopsy beforehand, a decision the Musikas later contested.

The Musikas argued that Dr. Gopez's actions during surgery, particularly his failure to conduct a needle biopsy, increased the risk of complications and necessitated further surgery at Massachusetts General Hospital. They claimed that Dr. Gopez's actions violated the standard of care, which should have included a more cautious approach to diagnosing and treating the tumor. The case was filed in October 2015, leading to a lengthy legal battle over the standard of care and the actions of the medical professionals involved.

The jury trial took place in November 2022, where the jury ultimately ruled that Dr. Gopez was not negligent. The Musikas subsequently filed a motion for post-trial relief, arguing that the trial court erred in excluding certain expert testimony and in not providing the jury with an instruction regarding the increased risk of harm due to Dr. Gopez's actions. They contended that this instruction was essential for the jury to understand the implications of the medical decisions made during John's treatment.

Judge Stabile, writing for the court, addressed the Musikas' claims regarding the exclusion of expert testimony and the jury instructions. The court ruled that the trial court acted within its discretion in excluding late-filed expert opinions and that the jury was adequately informed about the standard of care and the implications of Dr. Gopez's actions. The court noted that the Musikas could not demonstrate that the exclusion of this testimony was prejudicial to their case.

In its ruling, the court stated, "The trial court did not abuse its discretion in excluding testimony on the supplemental expert reports because they were filed on the eve of trial; Dr. Major’s supplemental report contained opinions beyond the scope of her original report; and Appellants were not prejudiced by the exclusion of either report." This ruling underscores the importance of adhering to procedural rules regarding expert testimony in medical malpractice cases.

The court also addressed the Musikas' argument regarding the jury instruction on increased risk of harm. While the court acknowledged that the instruction should have been provided, it ultimately concluded that the error was not prejudicial since the jury found Dr. Gopez was not negligent. The court emphasized that without a finding of negligence, the issue of causation and damages was moot.

The court's decision has implications for future medical malpractice cases, particularly regarding the standards for expert testimony and jury instructions. It reinforces the necessity for plaintiffs to establish a clear link between alleged negligence and the harm suffered, as well as the importance of timely presenting expert opinions during trial proceedings.

The Musikas have the option to appeal this ruling, but details on whether they will pursue further legal action were not available in the court filing. The case highlights the complexities involved in medical malpractice litigation, particularly in cases where diagnosis and treatment standards are in question.
