Benjamin Dubois, MD is a board-certified, fellowship-trained orthopedic shoulder surgeon at Grossmont Orthopaedic Medical Group on Grossmont Center Drive in La Mesa, near Sharp Grossmont Hospital. He earned his medical degree with Highest Distinction from the Keck School of Medicine at USC in 1998, completed his orthopedic residency and shoulder fellowship at the University of Washington, and has performed over 5,000 shoulder surgeries since joining the Grossmont practice in 2004—a surgical volume that generates acute referral pathways from facilities including Marque Urgent Care on Fletcher Parkway for traumatic rotator cuff and dislocation cases. Fellow of the American Academy of Orthopaedic Surgeons and co-founder of OrthoSono, a national musculoskeletal ultrasound education course launched in 2008, he has trained thousands of physicians on in-office shoulder ultrasound technique. His 100-percent shoulder-focused practice covers total and reverse shoulder replacement, arthroscopic rotator cuff repair, and ultrasound-guided platelet-rich-plasma injections, with post-surgical biomechanical rehabilitation routing through providers such as Awesome Family Chiropractic for long-term kinetic chain maintenance. Highest-complexity cases include revision reverse total shoulder arthroplasty with custom glenoid baseplate implantation for patients with severe bone loss following failed primary replacement.
