Arthroscopic Screw Fixation Technique for an Isolated Avulsion Fracture of the Lesser Tuberosity.

Isolated avulsion fractures of the lesser tuberosity of the humerus are rare and can be difficult to diagnose. This study presents a fully arthroscopic technique for anatomic reduction and screw fixation of these injuries. The described method allows precise visualization, fragment control, and secure fixation using standard arthroscopic portals and equipment. It also allows simultaneous assessment and treatment of concomitant intra-articular pathologies. This technique offers a minimally invasive alternative to traditional open surgery, providing advantages such as reduced postoperative pain, minimal scarring, and faster rehabilitation.
