A bipolar spacer was inserted for severe arthritic destruction of the shoulder in 14 patients, and followed up for a mean of 5.9 years. In one patient the operation failed because of infection. Two others required revision for loss of low-friction properties which caused loosening of the humeral component.

At the end of the follow-up all the patients showed improvement. The Hospital for Special Surgery pain score had increased from 5.3 to 18.9 and the movement score from 7.5 to 20.1.

Thirty-three patients with impingement syndrome of the rotator cuff were studied before and at operation. It was shown that the rotator cuff lengthens and twists during elevation of the arm. Elevation is achieved by early glenohumeral abduction and continuous flexion and external rotation. The range of free rotation at the glenohumeral joint diminishes progressively during elevation. Rotator cuff impingement occurs towards the end of the early glenohumeral abduction. Excision arthroplasty of the acromioclavicular joint and anterior acromioplasty is highly effective for impingement under the acromion, but only moderately effective where impingement is under the acromioclavicular joint.

Major ruptures of the rotator cuff were repaired in 89 patients over a six-year period, using an approach through the split deltoid muscle and the bed of the excised outer centimetre of the clavicle. Review of these patients showed that poor results were associated with larger cuff defects, with more pre-operative steroid injections and with pre-operative weakness of the deltoid muscle. A randomised prospective study showed that repair followed by splinting in abduction gave no better results than repair followed by resting the arm at the side. Excision of the coraco-acromial ligament was associated with worse results than leaving its divided halves in situ. Follow-up showed that the results continued to improve for two years after operation; their quality was maintained in patients less than 60 years old, but in those over 60 there was deterioration with time.

Twenty-three patients with a severe refractory painful arc syndrome have been treated by excision of the outer end of the clavicle and division of the coracoacromial ligament through a deltoid-splitting approach. After a follow-up of more than six months all patients have been relieved of night pain. Six still have slight pain on movement, but the rest are symptom-free.

Ninety-seven patients suffering from painful arc syndrome of the shoulder were studied. Local anaesthetic and radiographic contrast investigations were carried out. One-third of the patients had lesions in the posterior part of the rotator cuff which resolved after injections of local anaesthetic and steroid. One-third had anterior lesions in the subscapularis tendon: almost all resolved under the same regime but two required division of the coraco-acromial ligament. The remaining third had lesions of the supraspinatus tendon, usually associated with degeneration of the acromio-clavicular joint: most of these failed to gain relief from the local anaesthetic and steroid. Twenty-two operations were performed either by a transcromial or by a deltoid splitting approach. Excision of the outer end of the clavicle and division of the coraco-acromial ligament abolished the pain in most cases.
