Arthroscopic osteosynthesis of capitellum fractures: Feasibility study and clinical study on 2 cases

The current management of displaced capitellum fractures is traditionally surgical. Most authors perform open reduction and internal fixation. working hypothesis was that closed fixation achievable by arthroscopy. We carried out a cadaveric study on six fresh frozen elbows. performed two Bryan Morrey type I the capitellum, three II one IV using 15 mm osteotome. Fracture under arthroscopy probe hook an aiming femoral instrument set. Fixation with lag screw radioscopic control. reviewed, patients who had been operated for fracture osteosynthesized 7.5 years follow-up. In our study, we obtained anatomical stable osteosynthesis in four cases. failures (2 fractures) due to fragment during screwing. clinical range motion very satisfactory only 5° extension deficit. x-rays did not reveal any signs osteoarthritis or periarticular ossification. One patient minimal osteonecrosis. Arthroscopic feasible reproducible. recommend cannulated screws adjustable lock pins fractures. have shown this technique gives good results 7.5-year IV.
