PART I Exposures

●● Proceed as shown in Figure 1B-31A and B completely elevating the anconeus from the ulna and releasing from its humeral attachment. ●● At this point, the lateral collateral ligament is released from the humerus (Fig. 1B-32). ●● The triceps is easily elevated from the posterior humerus in the normal situation, and even in posttraumatic contractures, it can be elevated with a periosteal elevator without much additional difficulty (Fig. 1B-33). ●● A varus supinatory stress is applied to the elbow, which then opens like a book hinging on the medial ulnar collateral ligament and common flexor muscles (Fig. 1B-34). The triceps remains attached to the ulna. Inspect the ulnar nerve to be sure it is not being compressed. If it is, release it from the cubital tunnel.
