Philosophy of Care
I am committed to providing the highest level of quality and compassionate care to my patients. I believe that excellent outcomes are achieved by applying the best available scientific evidence to the needs of each individual patient. My ultimate goal is to empower patients and their families to make the best possible informed decisions regarding their treatment options.
Clinical Interests
Dr. Bayne specializes in the surgical care of the shoulder, elbow, hand, wrist, and peripheral nerves, with expertise in arthroscopy, joint replacement and reconstruction, and complex nerve procedures. With more than a decade of experience in upper-extremity surgery, his clinical focus includes shoulder arthroplasty, rotator-cuff repair, management of upper-extremity instability, and hand and wrist pathology. After completing medical school at Harvard University, orthopedic residency at Rush University Medical Center, and hand and upper-extremity fellowship training at the Mayo Clinic, he pursued advanced fellowship training in shoulder arthroplasty, arthroscopy, and upper-extremity reconstruction at the Institut de Chirurgie Réparatrice Locomoteur et Sports in Nice, France—an internationally recognized center for complex shoulder surgery and arthroscopic innovation. He is grateful to have trained at these world-class institutions, which shape his commitment to excellence in patient care.
Research/Academic Interests
Dr. Bayne’s research explores the biomechanics and clinical outcomes of upper extremity surgery, spanning both shoulder and hand/wrist reconstruction. His work examines shoulder arthroplasty performance, rotator cuff biomechanics, and mechanisms of carpal instability. He is dedicated to using data-driven insights to refine surgical techniques and improve patient outcomes across the spectrum of upper extremity care.
