Between 1980 and 1994, 221 shoulders with recurrent anterior glenohumeral subluxation or dislocation were reconstructed at our institution. At the time of the operation, thirteen shoulders were found to have an irreparable injury of the subscapularis muscle, which we believed to be a contributing factor to the ongoing instability. All but three of the(More)
Increases security of fixation in rotator cuff repair is usually achieved by increasing the strength of fixation. Paradoxically, the problem can be approached by techniques that decrease the strain at the margins of the tear so that weaker fixation will still be adequate. Such techniques provide greater safety tolerances for the strength characteristics of(More)
Current indications for shoulder arthrodesis include posttraumatic brachial plexus injuries, paralysis of the deltoid muscle and rotator cuff, chronic infection, failed revision arthroplasty, severe refractory instability, and bone deficiency following resection of a tumor in the proximal aspect of the humerus. The trapezius, levator scapulae, serratus(More)
The results of resection of the medial end of the clavicle to treat a painful sternoclavicular joint in fifteen patients were retrospectively reviewed. The patients fell into two groups: eight patients who had had a primary arthroplasty of the sternoclavicular joint in which the costoclavicular ligament was left intact (group I), and seven patients who had(More)
The authors report on a technique for the treatment of symptomatic, chronic complete dislocations of the acromioclavicular joint. The coracoacromial ligament is substituted for the coracoclavicular ligaments, and a special temporary coracoclavicular lag screw is used to stabilize the clavicle to the coracoid during ligament healing. The technique has been(More)
Early and mid-range followup studies of shoulder arthroplasty have been encouraging, showing good and excellent results in > 90% of shoulders. Despite this success, complications in shoulder replacement surgery are inevitable, with an incidence of approximately 14%. Numerous complications have been identified and include the following factors in order of(More)
PURPOSE The purpose of this study was to describe the anatomic footprint of the subscapularis tendon. METHODS We examined 19 cadaveric shoulder specimens in this study. Dissection was carried out to the level of the subscapularis through a deltopectoral approach. The subscapularis tendon was identified, and the dissection was continued, elevating the(More)
Secure arthroscopic repair of rotator cuff tears and Bankart lesions requires tight knots (knot security). Equally important, but usually overlooked, is the tightness of the suture loop (loop security). This study compared loop security in knots tied with No. 1 PDS suture using three different methods: (1) hand-tied, (2) single-hole standard knot pusher,(More)
We reviewed the records of sixteen patients, fifteen to sixty-two years old, who had glenoid hypoplasia with or without an associated deformity of the humeral head. The patients were divided into three groups: those who had bilateral glenoid hypoplasia without instability of the shoulder (Group I), those who had bilateral glenoid hypoplasia with instability(More)
