Novel Technique for Depressed Humeral Head Fractures: Arthroscopic Reduction and Subchondral Buttress Fixation Using a Polyaxial Locking Plate

Humeral head fractures, though relatively rare, pose significant challenges due to the risk of complications such as osteoarthritis and avascular necrosis. Particularly in younger patients, joint-preserving procedures are prioritized over arthroplasty, and their higher activity demands necessitate more precise and reliable reduction and fixation. We have developed a less invasive, more accurate, and more stable surgical technique utilizing arthroscopy and a polyaxial locking plate. Since this approach resulted in a favorable clinical outcome, we describe this technique comprehensively.
