A medical malpractice lawsuit has been filed against a local orthopedic surgeon and his practice, alleging negligence during a surgical procedure that resulted in severe and permanent damage to the patient. On May 2, 2025, Dianna Bates initiated legal action in the Circuit Court of Cook County, Illinois, targeting Genesis Orthopedics & Sports Medicine, LLC, and Dr. Nolan Horner for their alleged misconduct.
The complaint arises from a surgery performed on June 23, 2023, at West Suburban Medical Center in Oak Park, Illinois. Bates claims that Dr. Horner negligently performed a biceps tendonitis procedure by improperly tacking the biceps tendon over critical structures such as the median nerve and brachial artery. This alleged error has reportedly caused Bates significant pain and limited functionality in her left arm and hand. The plaintiff contends that this has not only necessitated ongoing medical care but also severely impacted her quality of life.
According to the filing, Dr. Horner was acting within his professional capacity as an orthopedic surgeon under Genesis Orthopedics & Sports Medicine at the time of the incident. The lawsuit asserts that Horner breached his duty of care by failing to exercise the knowledge and skill expected of reasonably careful orthopedic surgeons. As a result of this breach, Bates alleges she suffered severe injuries that have led to enduring physical limitations.
In her complaint, Bates is seeking judgment against both defendants for damages exceeding $50,000. She is also requesting prejudgment interest and court costs as permitted by law. The case underscores significant concerns about medical standards and patient safety within surgical practices.
Representing Dianna Bates is attorney Hall Adams from the Law Offices of Hall Adams located in Chicago. The case is identified under Case ID 2025L005865 with Mariyana T. Spyropoulos serving as Circuit Clerk for Cook County's Law Division.
