The results of 140 total hip revision procedures for "non-septic" loosening, dislocation, and fracture of the femoral stem or shaft have been personally reviewed and rated by the Harris method. The minimum follow-up period was six months: thirty-three (24 per cent) showed excellent or good results, seventy-two (51 per cent) showed fair or poor results. Subsequent excision arthroplasty was performed in thirty-one patients. The infection rate for these revision procedures was very high, suggesting that many were already infected at the time of revision, and that every "loose" hip must be assumed to be infected until proved otherwise. The mortality rate of 3 per cent was surprisingly low after more than one major surgical procedure in these elderly patients.

The painful arc syndrome may be produced by impingement of the supraspinatus tendon, the biceps tendon, or the greater tuberosity of the humerus against the coracoacromial arch. Where conservative measures have failed, surgical intervention may provide considerable symptomatic relief by decompressing the coracoacromial arch. In 20 cases surgically treated for biceps or supraspinatus impingements, 17 patients have returned to sporting activities without symptoms. The painful arc syndrome persists in three patients but they are symptomatically improved. Six patients with complete rotator cuff tears and subsequent impingement of the greater tuberosity of the humerus against the coracoacromial arch underwent widespread decompression. Five of the patients have returned to sporting activities much improved. Failure to recognize the associated acromioclavicular joint pathology is a frequent cause of failure of surgical treatment.
