●● The anconeus is released from the triceps, the ulnohumeral capsule is incised and the nonarticular portion of the greater sigmoid notch is identified. ●● A Chevron osteotomy is performed, apex distal with a depth of 5 to 10 mm (Fig. 1B-6). Protect the ulnar nerve medially. Use osteotome to crack last few millimeters to assure accurate subse- quent reduction. ●● The olecranon fragment is reflected proximally exposing the distal humerus (Fig. 1B-7). ●● Repair uses the AO-K-wire, tension band technique with the wires in the anterior cortex, not down the canal (Fig. 1B-8).
