Outcome of nonoperative management of full-thickness rotator cuff tears.

The study documented the functional outcome in a consecutive series of 46 patients from an individual practice meeting the inclusion criteria of (1) a full-thickness rotator cuff tear seen by ultrasonography, arthrogram, or magnetic resonance imaging, (2) absence of a Workers' Compensation claim or previous surgery, (3) followup of at least 1 year, and (4) election of nonoperative management by the patient. Twenty-six of the tears involved only the supraspinatus, two involved the supraspinatus and infraspinatus, and two involved the supraspinatus, infraspinatus, and subscapularis (16 reports did not specify the size of the tear). Treatment consisted only of patient education and a home program of gentle stretching and strengthening. Patients completed the Simple Shoulder Test at the initial visit and sequentially at 6-month intervals thereafter. At an average followup of 2.5+/-1.6 years, 27 (59%) patients experienced improvement with nonoperative treatment, 14 (30%) patients experienced worsening, and five (11%) patients remained unchanged. The average number of Simple Shoulder Test functions the patients could perform initially was 5.6+/-3.2. At the latest followup, the average number of Simple Shoulder Test functions the patients could perform improved to 7.0 +/-3.8. The ability to sleep on the affected side and the ability to place the hand behind the head were significantly improved.
