Abstract:
[Objective]To explore the operative techniques of open reduction and internal fixation of displaced radial head fractures in adults. [Methods]Twenty-six cases of radial head fractures had been treated with open reduction and internal fixation. According to Mason classification, 16 fractures were type II, 6 were type III and 4 were type IV. Operative exposures of radial head were performed through the Kocher approach in 22 cases, and through a midline posterior skin incision in 4 cases in order to repair concomitant fracture of proximal ulna. After being reduced, fractures of radial head were fixed with mini-fragment plate and screw which were placed in "safe zone" not to impinge on the proximal radioulnar joint with forearm rotation.[Results]At a mean follow-up of 32 months, all fractures had united. There was no patient who suffered from wound infection or injury to posterior interosseous nerve. According to the Broberg and Morrey functional elbow index, the outcome were excellent in 17 patients, good in 9.[Conclusion]Open reduction and internal fixation of displaced radial head fractures may get satisfying outcomes, with successful performing of the requirements below: (1) sustaining lateral ulnar collateral ligament; (2) avoiding injury to posterior inerosseous nerve; (3) getting anatomic reduction; (4) stably fixing fractures without impinging on joint.
