2General considerations

Lesser tuberosity reduction

Proper reduction of the lesser tuberosity is difficult. Its position is hard to visualize with intraoperative image intensification.

Medial displacement of the lesser tuberosity (A) produces an intraarticular anterior step which can compromise internal rotation.

Lateral displacement of the lesser tuberosity (B) obstructs the bicipital groove and may compromise the biceps tendon. If possible, correct reconstruction of the bicipital groove is desirable to allow sliding of the tendon. An alternative would be a tenotomy or tenodesis of the long head of the biceps.
