Jason has participated in the following trials to verdict:

  • In Madison County, Illinois. (Medical Malpractice Claim for $1.25 million. Result: jury verdict for defense on all counts). Our client, a radiologist, performed a lumbar spine MRI diagnosing herniated disc and degenerative changes. Subsequently, a repeat MRI showed a spinal infection requiring a multi-level laminectomy surgery and extensive rehabilitation therapy for the patient. The defense was based on a denial of any deviation in the standard of care, and a denial that the spinal infection existed at the time of the MRI read by our client. After a 6-day trial, the jury returned a verdict in favor of the defendants.

  • In Jackson County, Illinois. (Medical Malpractice claim for $860,000.00. Result: jury verdict for defense on all counts.) Our client, a podiatric surgeon, performed a retrocalcaneal exostectomy procedure on the plaintiff's left heel. This involved a partial achilles tendon release and reattachment using collagen implant anchors. The plaintiff had complications postoperatively, including a foreign body reaction to the anchors. This resulted in two subsequent revision surgeries, and a claim of permanent chronic pain and suffering and partial disability. Plaintiff also claimed lack of informed consent. The defense was based upon  a denial of any deviation of acceptable standards of podiatric care. The defense was also based upon the assertion that appropriate informed consent was obtained. After deliberation, the jury returned the verdict in favor of defendants on all counts.
  • In Marion County, Illinois. (Medical malpractice claim for $1.9 million. Result: jury verdict for defense.) Our client, a podiatric surgeon, performed plantar fasciotomy surgery and Achilles tendon lengthening surgery on the right foot of plaintiff. Complications arose, and plaintiff generally alleged that she had a protracted recovery which resulted in reflex sympathetic dystrophy that was not diagnosed in a timely fashion. Plaintiff underwent a subsequent surgery to her Achilles tendon, and also underwent a procedure to permanently insert a spinal cord stimulator to address the chronic reflex sympathetic dystrophy. The defense was based upon a denial of any deviation of acceptable standards of podiatric care, and a denial of proximate cause. After deliberation, the jury returned a verdict in favor of defendant.
