[Anterior transbrachial approach of the coronoid apophysis]

Fractures of the coronoid process of the ulna can cause elbow instability. Treatment of these fractures, sometimes surgical, raises a problem of the incision. The incisions described to date do not provide specific exposure, or require sometimes dangerous nerve and vascular dissections. The authors propose a strictly brachial midline anterior incision. The biceps tendon is retracted laterally and the brachialis muscle is then dissociated longitudinally providing direct exposure of the coronoid process, with no risk of nerve lesions, and allowing direct screwing of the fracture.
