We performed eight osteochondral autologous transplantations from the knee joint to the shoulder. All patients (six men, two women; mean age 43.1 years) were documented prospectively. In each patient the stage of the osteochondral lesion was Outerbridge grade IV with a mean size of the affected area of 150 mm. 2. All patients were assessed by using the Constant score for the shoulder and the Lysholm score for the knee. Standard radiographs, magnetic resonance imaging and second-look arthroscopy were used to assess the presence of glenohumeral osteoarthritis and the integrity of the grafts. After a mean of 32.6 months (8 to 47), the mean Constant score increased significantly. Magnetic resonance imaging revealed good osseointegration of the osteochondral plugs and congruent articular cartilage at the transplantation site in all but one patient. Second-look arthroscopy performed in two cases revealed a macroscopically good integration of the autograft with an intact articular surface. Osteochondral autologous transplantation in the shoulder appears to offer good clinical results for treating full-thickness osteochondral lesions of the glenohumeral joint. However, our study suggests that the development of osteoarthritis and the progression of pre-existing osteoarthritic changes cannot be altered by this technique

The management and outcome of treatment in 42 patients (49 shoulders) with an infected shoulder prosthesis was reviewed in a retrospective multicentre study of 2343 prostheses. The factors which were analysed included the primary diagnosis, the delay between the diagnosis of infection and treatment and the type of treatment. Treatment was considered to be successful in 30 patients (71%). Previous surgery and radiotherapy were identified as risk factors for the development of infection. All patients with an infected prosthesis had pain and limitation of movement and 88% showed radiological loosening. In 50% of the shoulders, the antibiotics chosen and the length of treatment were considered not to be optimal. The mean follow-up was 34 months. Antibiotics or debridement alone were ineffective. In acute infection, immediate revision with excision of all infected tissue and exchange of the prosthesis with appropriate antibiotic therapy gave the best results. Multidisciplinary collaboration is recommended

1. A case of recurrent posterior subluxation of the shoulder is described. After failure of a soft-tissue repair, a posterior bone block operation was performed. 2. The distinction between traumatic dislocations with tearing of the capsule or of the glenoid labrum, and habitual luxations from laxity of the capsule, is emphasised. Although the anterior rim of the glenoid was detached in this case, it is considered to fall into the latter category. 3. A posterior bone block provides a simple and efficient form of repair in this type of case. It is free from the disadvantage of causing limitation of rotation at the shoulder joint; it employs a principle which might well merit more application than at present in the repair of anterior dislocations

We report a randomised controlled trial to examine the effectiveness and cost-effectiveness of arthroscopic acromioplasty in the treatment of stage II shoulder impingement syndrome. A total of 140 patients were randomly divided into two treatment groups: supervised exercise programme (n = 70, exercise group) and arthroscopic acromioplasty followed by a similar exercise programme (n = 70, combined treatment group). The main outcome measure was self-reported pain on a visual analogue scale of 0 to 10 at 24 months, measured on the 134 patients (66 in the exercise group and 68 in the combined treatment group) for whom endpoint data were available. An intention-to-treat analysis disclosed an improvement in both groups but without statistically significant difference in outcome between the groups (p = 0.65). The combined treatment was considerably more costly. Arthroscopic acromioplasty provides no clinically important effects over a structured and supervised exercise programme alone in terms of subjective outcome or cost-effectiveness when measured at 24 months. Structured exercise treatment should be the basis for treatment of shoulder impingement syndrome, with operative treatment offered judiciously until its true merit is proven

A new technique of shoulder fusion is presented using a posterior approach. After removal of the articular cartilage, a Rush pin is introduced from the spine of the scapula, through the glenoid into the medullary canal of the humerus. This is supplemented by tension-band wiring from the acromion to the neck of the humerus and a muscle pedicle graft attached to the acromion. A shoulder spica is applied for four to six weeks. Four patients with injuries to the upper brachial plexus and 14 with paralysis of the upper arm due to anterior poliomyelitis have been followed for three years. One of the 18 patients developed nonunion; she had removed her own cast prematurely. This method of fixation provides high shear resistance and low axial stiffness without deforming plastically. It does not affect bone growth in young patients, is effective in patients with osteoporosis, and gives a high rate of union

We diagnosed 50 patients (58 shoulders) with a mean age at presentation of 17.3 years, as having involuntary positional instability of the shoulder. They were managed by a programme consisting of a careful explanation, analysis of abnormal muscle couples and then muscle retraining carried out by a specialist physiotherapist. The mean follow-up was two years. Six shoulders had a poor result, but 52 were graded as good to excellent. Nine patients (12 shoulders) relapsed and required further episodes of retraining. In our experience, involuntary positional instability of the shoulder causes symptoms which interfere with normal activities; these can be controlled by a treatment plan of retraining of the muscle pattern with functional benefit. Only 19 of the patients were referred with a diagnosis of positional instability. There should be more awareness of this rather uncommon condition. Surgery is not indicated in these patients

We measured torsion of the humeral head in 38 patients (40 shoulders) with recurrent anterior dislocation of the shoulder (RADS) and in 40 normal subjects. We found a reduced mean retroversion in the patients with RADS at 4.3 +/- 10.56 degrees (17 degrees anteversion to 32 degrees retroversion) as compared with 16.1 +/- 11.07 degrees in the control group (0 degrees to 49 degrees) (p = 0.0001). There was anteversion in 11 of the 40 shoulders in the RADS group (27.5%) and in none of the control group. The first dislocation had occurred after minimal force in 18 of 25 patients with less than 10 degrees retroversion, but in only three of 15 with over 10 degrees retroversion. We conclude that decreased retroversion of the humeral head is often associated with RADS and with first dislocation of the shoulder caused by minimal force

Residual muscle weakness in obstetric brachial plexus palsy results in soft-tissue contractures which limit the functional range of movement and lead to progressive glenoid dysplasia and joint instability. We describe the results of surgical treatment in 98 patients (mean age 2.5 years, 0.5 to 9.0) for the correction of active abduction of the shoulder. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and axillary nerve decompression and neurolysis (the modified Quad procedure). The transferred muscles were sutured to the teres minor muscle, not to a point of bony insertion. The mean pre-operative active abduction was 45° (20° to 90°). At a mean follow-up of 4.8 years (2.0 to 8.7), the mean active abduction was 162° (100° to 180°) while 77 (78.6%) of the patients had active abduction of 160° or more. No decline in abduction was noted among the 29 patients (29.6%) followed up for six years or more. This procedure involving release of the contracted internal rotators of the shoulder combined with decompression and neurolysis of the axillary nerve greatly improves active abduction in young patients with muscle imbalance secondary to obstetric brachial plexus palsy

The results of 63 operative repairs of chronic tears of the rotator cuff in 61 patients are reviewed retrospectively; the mean follow-up was 32.7 months. Fifty-four patients presented with symptoms of persistent pain and seven patients with gross loss of movement. All the patients had failed to respond to conservative treatment. Results were assessed in terms of relief of pain, restoration of movement, the patients' ability to return to work and whether they were satisfied with the results. Overall, a good result in terms of relief of pain was achieved in 40 shoulders. In 31 shoulders (30 with pain and one without pain) the operation included particular measures to decompress the subacromial space; 26 of the patients achieved relief of pain which was significantly better than in those patients whose operation did not include a decompression. The complications and failures are discussed. It is suggested that operative repair of the chronically torn rotator cuff of the shoulder is a worthwhile operation and that the operation should include an adequate decompression of the subacromial space

A reduced retroversion angle of the humeral head may predispose to recurrent anterior shoulder dislocation and may also be a factor in persistent instability after soft-tissue repair. We performed rotational osteotomy of the proximal humerus in 20 patients with recurrent anterior shoulder dislocations (10 traumatic, 10 non-traumatic) and a decreased retroversion angle of the humeral head. The mean preoperative retroversion angle was 12 degrees, which was increased after surgery to a mean value of 32 degrees. All patients regained a normal range of shoulder motion and normal function within three months after surgery. At the five-year review all shoulders were stable, pain-free and had no radiological signs of osteoarthritis

Resurfacing of the humeral head is commonly used within the UK to treat osteoarthritis (OA) of the shoulder. We present the results of a small prospective randomised study of this procedure using the Global CAP prosthesis with two different coatings, Porocoat and DuoFix hydroxyapatite (HA). We followed two groups of ten patients with OA of the shoulder for two years after insertion of the prosthesis with tantalum marker beads, recording pain, Constant–Murley and American Shoulder and Elbow Surgeons (ASES) outcome scores, and using radiostereometric analysis to assess migration. The outcomes were similar to those of other series, with significant reductions in pain (p = 0.003) and an improvement in the Constant (p = 0.001) and ASES scores (p = 0.006). The mean migration of the prosthesis three months post-operatively was 0.78 mm (0.51 to 1.69) and 0.72 mm (0.33 to 1.45) for the Porocoat and DuoFix groups, respectively. Analysis of variance indicated that the rate of migration reached a plateau after three months post-operatively in both groups. At follow-up of two years the mean migration was 1 mm (. sd. 1 (0.25 to 3.32)); in the Porocoat group and 0.8 mm (. sd. 0.4 (0.27 to 1.45)) in the DuoFix HA group. Significant migration of the prosthesis was seen in one patient who had received an anterior humeral bone graft. This prosthesis was later revised after 2.7 years. The addition of a coating of HA to the sintered surface does not improve fixation of this prosthesis. Cite this article: Bone Joint J 2014;96-B:1077–81

Objectives. To report the five-year results of a randomised controlled trial examining the effectiveness of arthroscopic acromioplasty in the treatment of stage II shoulder impingement syndrome. Methods. A total of 140 patients were randomly divided into two groups: 1) supervised exercise programme (n = 70, exercise group); and 2) arthroscopic acromioplasty followed by a similar exercise programme (n = 70, combined treatment group). Results. The main outcome measure was self-reported pain as measured on a visual analogue scale. At the five-year assessment a total of 109 patients were examined (52 in the exercise group and 57 in the combined treatment group). There was a significant decrease in mean self-reported pain on the VAS between baseline and the five-year follow-up in both the exercise group (from 6.5 (1 to 10) to 2.2 (0 to 8); p < 0.001) and the combined treatment group (from 6.4 (2 to 10) to 1.9 (0 to 8); p < 0.001). The same trend was seen in the secondary outcome measures (disability, working ability, pain at night, Shoulder Disability Questionnaire and reported painful days). An intention-to-treat analysis showed statistically significant improvements in both groups at five years compared with baseline. Further, improvement continued between the two- and five-year timepoints. No statistically significant differences were found in the patient-centred primary and secondary parameters between the two treatment groups. Conclusions. Differences in the patient-centred primary and secondary parameters between the two treatment groups were not statistically significant, suggesting that acromioplasty is not cost-effective. Structured exercise treatment seems to be the treatment of choice for shoulder impingement syndrome

Aims. The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair. Patients and Methods. All patients with a history of rotator cuff repair who underwent RSA between 2000 and 2015 with a minimum follow-up of two years were eligible for inclusion as the study group. Outcomes, including the American Shoulder and Elbow Surgeons (ASES) scores, were compared with a matched control group of patients who underwent RSA without having previously undergone rotator cuff repair. Results. The study group included 45 patients. Their mean age was 69 years (. sd. 8.6) and 27 patients (60%) were women. The mean ASES score improved from 43.1 to 76.6 two years postoperatively, and to 66.9 five years postoperatively. There was no significant difference between the outcomes at two years in the two groups (all p ≥ 0.05), although there was significantly more improvement in ASES scores in the control group (44.5 vs 33.4; p = 0.01). However, there was no significant difference between ASES scores at two and five years when baseline ASES scores were matched in the two groups (p = 0.42 at two years; p = 0.35 at five years). Conclusion. Significant improvements in ASES scores were seen following RSA in patients who had previously undergone rotator cuff repair. They had higher baseline ASES scores than those who had not previously undergone this surgery. However, there was no significant difference in outcomes between the two groups, two years postoperatively. Previous rotator cuff repair does not appear to affect the early outcome after RSA adversely

1. Coracoid transplantation for recurring dislocation of the shoulder is described. 2. In my experience of over thirty cases only once has true dislocation recurred after this operation. Recurrence was due to avulsion of the bone block. 3. Failure to repair the original detachment of the glenoid labrum is a frequent cause of recurrence of dislocation of the shoulder. An explanation is offered for this failure; namely that the injured labrum adheres to the deep surface of the subscapularis muscle instead of reattaching itself to bone. This reinforces Watson-Jones's advice that the original dislocation should be treated by complete immobilisation in full medial rotation for three weeks

A man of 52 years of age had a grand mal seizure. He presented to our unit three months later with irreducible bilateral posterior dislocation of the shoulder. CT scans revealed large compression defects on the anteromedial aspect of the heads of both humeri. The defect on the right side was of more than 50% of the articular surface, and on the left side of 40%. He was treated by a one-stage operation with a hemiarthroplasty on one side and reconstruction of the head by an osteochondral autograft on the other. Three years later the clinical and radiological results were excellent
