Master Tech Ortho Surgery Elbow CH1
PART I Exposures
Position Supine, arm on an elbow board. Skin Incision Proceeds from 5 cm proximal to 7 cm distal to the medial epicondyle passing posterior to the epicondyle near the midline. Technique ●● The medial epicondyle is identified along with the ulnar nerve. The ulnar nerve is elevated from its proximal attachment, the cubital tunnel retinaculum is released, and the nerve is exposed to the first motor branch (Fig. 1B-54). ●● The flexor carpi ulnaris is split, allowing the ulnar nerve to be further mobilized. The sublime tubercle is palpated in the depths of the wound (Fig. 1B-55). ●● Sharp dissection frees the muscle mass from the anterior (Fig. 1B-56) and posterior aspects of the capsule (Fig. 1B-57).
