Surgical technique for exposure of posterior proximal radius and ulna. Arm of supine patient is pronated and draped over chest. Slightly curved incision is started 2.5 cm proximal to olecranon and extended subcutaneously to 1/4 length of proximal ulna; insertion of anconeus is sharply dissected off olecranon; and anconeus muscle and extensor carpi radius are retracted medially off ulna along with origin of supinator (which requires subperiosteal elevation). Interosseous recurrent artery can be ligated if more exposure is needed.
