The operative treatment of septic arthritis of the shoulder in infants has been facilitated by the use of a 30° wrist arthroscope. We have treated three children under the age of three years using this technique. After initial aspiration of the joint, an arthroscope was inserted using the posterior approach. Washout was performed under direct vision and complete clearance of pus allowed assessment of the inflammation and the damage to articular cartilage. The procedure was minimally invasive and gave excellent cosmesis without compromising care. Full recovery was achieved with a single intervention

Opinion varies as to the incidence of nerve lesions in anterior dislocation of the shoulder after low-velocity trauma. Most studies are retrospective or do not use EMG. We have investigated the incidence and the clinical consequences of nerve lesions in a prospective study by clinical and electrophysiological examination. Axonal loss was seen in 48% of 77 patients. The axillary nerve was most frequently involved (42%). Although recovery as judged by EMG and muscle strength was almost complete, function of the shoulder was significantly impaired in patients with lesions of the axillary and suprascapular nerves. Unfavourable prognostic factors are increasing age and the presence of a haematoma. It is not necessary to carry out EMG routinely; an adequate programme of physiotherapy is important. In patients with a severe paresis, EMG is essential after three weeks

Arthroscopic surgery of the shoulder was performed on 439 patients over a 10-year period: these patients are reviewed after a minimum follow-up of one year. Diagnostic arthroscopy is known to be valuable and we have found that arthroscopic surgery also is safe and effective. It was useful in treating frozen shoulder, early osteoarthritis, isolated tears of the glenoid labrum and lesions of the biceps tendon. It was less useful in treating partial tears of the rotator cuff, tendonitis and severe osteoarthritis, and of little value in treating complete tears of the rotator cuff or in treating patients in whom previous operations on the rotator cuff had failed. It may prove to be a useful method of performing synovectomy in rheumatoid arthritis and of treating instability

Both conservative and operative forms of treatment have been recommended for patients with a ‘floating shoulder’. We compared the results of conservative and operative treatment in 25 patients with this injury and investigated the use of the glenopolar angle (GPA) as an indicator of the functional outcome. A total of 13 patients (ten male and three female; mean age 32.5 years (24.7 to 40.4)) were treated conservatively and 12 patients (ten male and two female; mean age 33.67 years (24.6 to 42.7)) were treated operatively by fixation of the clavicular fracture alone. Outcome was assessed using the Herscovici score, which was also related to changes in the GPA at one year post-operatively. The mean Herscovici score was significantly better three months and two years after the injury in the operative group (p < 0.001 and p = 0.003, respectively). There was a negative correlation between the change in GPA and the Herscovici score at two years follow-up in both the conservative and operative groups, but neither were statistically significant (r = -0.295 and r = -0.19, respectively). There was a significant difference between the pre- and post-operative GPA in the operative group (p = 0.017). When compared with conservative treatment, fixation of the clavicle alone gives better results in the treatment of patients with a floating shoulder. The GPA changes significantly with fixation of clavicle alone but there is no significant correlation between the pre-injury GPA and the final clinical outcome in these patients.

1. Fifty cases of recurrent dislocation of the shoulder are reported, operated upon by Bankart and his colleagues from 1925 to 1954. 2. This is the first detailed survey of his patients, some of whom we were unable to trace. 3. It has been confirmed that the operation is successful, and that a full range of movement can be regained after operation, though not in every case. 4. Two cases treated unsuccessfully are described and discussed

Computerised arthrotomography was performed on 33 patients four to six weeks after acute primary anterior dislocation of the shoulder. Seventeen patients were under, and 16 over 50 years of age. Damage to the anterior glenoidal labrum was seen in all the younger patients and in 75% of the older ones. A large redundant capsular pouch, seen in the older patients, was present in 35% of the younger ones, and a posterior humeral head defect was seen in 82% of the younger patients and only 50% of the older. Associated fractures were more common in the older patients, and a tear of the rotator cuff was demonstrated in 63% of the older patients and in none of the younger ones

We reviewed 28 patients with brachial plexus lesions caused by shoulder dislocation. Contrary to most other reports, we found that the neurological lesions involved the infraclavicular and the supraclavicular brachial plexus. With supraclavicular lesions the involvement was always of the suprascapular nerve, and this always recovered spontaneously. Isolated axillary nerve lesions had the poorest prognosis for spontaneous recovery. We explored all lesions that showed no recovery after three to five months and performed either grafting or neurolysis. We discuss the combinations of nerve lesions, their recovery, the surgical indications, and the operations. We also suggest a new classification for these injuries which is more clinically relevant than the anatomical classification of Leffert and Seddon (1965)

Delay in the diagnosis of posterior shoulder dislocation is common. We present two such cases treated satisfactorily by rotation osteotomy of the surgical neck of the humerus and discuss the indications for this procedure

A reversed Delta III total shoulder prosthesis was retrieved post-mortem, eight months after implantation. A significant notch was evident at the inferior pole of the scapular neck which extended beyond the inferior fixation screw. This bone loss was associated with a corresponding, erosive defect of the polyethylene cup. Histological examination revealed a chronic foreign-body reaction in the joint capsule. There were, however, no histological signs of loosening of the glenoid base plate and the stability of the prosthetic articulation was only slightly reduced by the eroded rim of the cup

1. Resection of the shoulder for a malignant tumour involving the scapula which was too extensive for treatment by excision of the bone is described. 2. The procedure is suggested as an alternative to forequarter amputation in suitable instances

We report five patients who developed septic arthritis of the shoulder after cancer of the ipsilateral breast had been treated by surgery and radiotherapy. Lymphoedema was present in all cases. The infections were not obvious, having subacute onsets, and delays in diagnosis led to destruction of the joint in all but one patient

Experimental work has shown that dislocation of the shoulder may involve disruption of the capsule from its lateral humeral attachment. We report two patients with recurrent dislocation due to this injury. Lateral repair gave good results. It is suggested that this injury be considered and looked for when glenoid labral injury is minimal or absent

1. A case is described ofcomplete rupture ofthe second part of the axillary artery complicating anterior dislocation of the shoulder in a woman aged fifty years. 2. Interesting features were that the patient was comparatively young, that the rupture was a result of the dislocation and not of the reduction, that the axillary vein remained intact, and that a satisfactory circulation returned after ligation of the artery

A case of complete rupture of the axillary artery in a man aged eighty-seven is described. The injury occurred in connection with an antero-inferior dislocation of the shoulder. It is not known whether the rupture was caused by the dislocation itself or by the reduction. A successful suture of the artery was performed. A review of the literature is given, and earlier attempts to suture the artery in cases of this type are noted. The indications for this operation are discussed

We describe 11 cases of posterior fracture-dislocation of the shoulder that required open reduction and fixation. Difficulties with access through anterior approaches led us to use the superior subacromial approach. This is an extension of the approach often used to expose the rotator cuff; the joint is opened by splitting the supraspinatus tendon 5 mm behind the cuff interval. The glenoid, proximal humerus and any fracture fragments can be seen from above, allowing reduction of the dislocation and osteosynthesis to be performed with minimal risk of damage to the humeral head and its blood supply. The proximity of the axillary nerve limits the exposure of the proximal humeral shaft. The superior subacromial approach is ideal for posterior dislocation with fracture of the articular segment, but is not suitable when there is a fracture of the proximal humeral shaft

The purpose of this paper is to call attention to the anterior bone block method of Hybbinette-Eden for recurrent dislocation of the shoulder joint. 1. The operative technique is not difficult, and the after-treatment is short and relatively agreeable for the patient. 2. Sixty of our own cases are described, with four recurrences. The recurrences all occurred as the result of real trauma. In a total of 128 Scandinavian cases there were eight recurrences—that is 6·3 per cent. 3. In our opinion, based on the observations of radiography, arthrography, and operation, it is the compression fracture of the head of the humerus which deserves the name "essential lesion." Destruction of the anterior rim of the glenoid may be very slight, or entirely lacking. No false joint cavity or rupture big enough to receive the head of the humerus was ever observed by arthrography or by inspection during operative exploration. Recurrent dislocation is an intracapsular subluxation, which occurs when the anterior rim of the glenoid slides into the hollow in the humeral head

1. Three cases of abduction contracture of the shoulder caused by fibrosis of the intermediate part of the deltoid muscle are described. 2. Treatment by removal of the affected part of the muscle was successful in each case. 3. Histological findings are described and the nature of the condition is discussed

Four cases of posterior dislocation of the shoulder at birth in association with obstetric brachial plexus palsy are presented. Review of the literature suggests that this association is not generally recognised. All cases were diagnosed late; two were treated by open reduction, one by humeral osteotomy and one managed conservatively
