After establishing anatomical feasibility, functional reconstruction to replace the anterolateral part of the deltoid was performed in 20 consecutive patients with irreversible deltoid paralysis using the sternoclavicular portion of the pectoralis major muscle. The indication for reconstruction was deltoid deficiency combined with massive rotator cuff tear in 11 patients, brachial plexus palsy in seven, and an isolated axillary nerve lesion in two. All patients were followed clinically and radiologically for a mean of 70 months (24 to 125). The mean gender-adjusted Constant score increased from 28% (15% to 54%) to 51% (19% to 83%). Forward elevation improved by a mean of 37°, abduction by 30° and external rotation by 9°. The pectoralis inverse plasty may be used as a salvage procedure in irreversible deltoid deficiency, providing subjectively satisfying results. Active forward elevation and abduction can be significantly improved

Aims

To determine the role of early MRI in the management of suspected scaphoid fractures.

We investigated the role of a functional brace worn for four months in the treatment of patients with an acute isolated tear of the posterior cruciate ligament to determine whether reduction of the posterior tibial translation during the healing period would give an improved final position of the tibia. The initial and follow-up stability was tested by Rolimeter arthrometry and radiography. The clinical outcome was evaluated using the Lysholm score, the Tegner score and the International Knee Documentation Committee scoring system at follow-up at one and two years. In all, 21 patients were studied, 21 of whom had completed one-year and 17 a two-year follow-up. The initial mean posterior sag (Rolimeter measurement) of 7.1 mm (5 to 10) was significantly reduced after 12 months to a mean of 2.3 mm (0 to 6, p < 0.001) and to a mean of 3.2 mm (2 to 7, p = 0.001) after 24 months. Radiological measurement gave similar results. The mean pre-injury Lysholm score was normal at 98 (95 to 100). At follow-up, a slight decrease in the mean values was observed to 94.0 (79 to 100, p = 0.001) at one year and 94.0 (88 to 100, p = 0.027, at two years). We concluded that the posterior cruciate ligament has an intrinsic healing capacity and, if the posteriorly translated tibia is reduced to a physiological position, it can heal with less attentuation. The applied treatment produces a good to excellent functional result

Our aim in this prospective study was to evaluate the outcome of total shoulder replacement in the treatment of young and middle-aged active patients with primary glenohumeral osteoarthritis. We reviewed 21 patients (21 shoulders) with a mean age of 55 years (37 to 60). The mean follow-up was seven years (5 to 9). The same anatomical, third-generation, cemented implant had been used in all patients. All the patients were evaluated radiologically and clinically using the Constant and Murley score. No patients required revision. In one a tear of the supraspinatus tendon occurred. Overall, 20 patients (95%) were either very satisfied (n = 18) or satisfied (n = 2) with the outcome. Significant differences (p < 0.0001) were found for all categories of the Constant and Murley score pre- and post-operatively. The mean Constant and Murley score increased from 24.1 points (10 to 45) to 64.5 points (39 to 93), and the relative score from 30.4% (11% to 50%) to 83% (54% to 116%). No clinical or radiological signs of loosening of the implant were seen. For young and middle-aged patients with osteoarthritis, third-generation total shoulder replacement is a viable method of treatment with a low rate of complications and excellent results in the mid-term

Aims. Despite the expansion of arthroscopic surgery of the shoulder, the open deltopectoral approach is increasingly used for the fixation of fractures and arthroplasty of the shoulder. The anatomy of the terminal branches of the posterior circumflex humeral artery (PCHA) has not been described before. We undertook an investigation to correct this omission. Patients and Methods. The vascular anatomy encountered during 100 consecutive elective deltopectoral approaches was recorded, and the common variants of the terminal branches of the PCHA are described. Results. In total, 92 patients (92%) had a terminal branch that crossed the space between the deltoid and the proximal humerus and which was therefore vulnerable to tearing or avulsion during the insertion of the blade of a retractor during the deltopectoral approach to the shoulder. In 75 patients (75%) there was a single vessel, in 16 (16%) a double vessel and in one a triple vessel. Conclusion. The relationship of these vessels to the landmark of the tendon of the insertion of pectoralis major into the proximal humerus is described. Damage to these previously undocumented branches can cause persistent bleeding leading to prolonged surgery and post-operative haematoma and infection, as well as poor visualisation during the procedure.

We treated eight dysplastic acetabula in six skeletally mature patients with Down’s syndrome by a modified Bernese periacetabular osteotomy. The mean age at the time of surgery was 16.5 years (12.8 to 28.5). Mean length of follow-up was five years (2 to 10.4). Pre-operatively the mean (Tönnis) acetabular angle was 28°, the centre-edge angle was −9°, and the extrusion index was 60%; post-operatively they were 3°, 37°, and 17%, respectively. Two patients with post-operative (Tönnis) acetabular angles > 10° developed subluxation post-operatively and required secondary varus derotation femoral osteotomies. Another patient developed a late labral tear which was treated arthroscopically. All eight hips remain clinically stable, and are either asymptomatic or symptomatically improved. These results suggest that the modified Bernese periacetabular osteotomy can be used successfully in the treatment of acetabular dysplasia in patients with Down’s syndrome

Aims

Functional rehabilitation has become an increasingly popular treatment for Achilles tendon rupture (ATR), providing comparably low re-rupture rates to surgery, while avoiding risks of surgical complications. Limited evidence exists on whether gap size should affect patient selection for this treatment option. The aim of this study was to assess if size of gap between ruptured tendon ends affects patient-reported outcome following ATR treated with functional rehabilitation.

1. The lesions chiefly responsible for persistent pain and weakness after acromio-clavicular dislocations are tears of the trapezius and deltoid muscles. 2. These tears cannot be adequately treated except by open operation. 3. There are often physical barriers making closed manipulative reduction impossible. 4. Open reduction and repair of torn ligaments and muscle is advocated for manual workers

Of 250 patients scheduled for meniscectomy 50 had symptoms which subsided and operation could be deferred; of the remaining 200 only 73 per cent were found to have a significant tear. It is shown that the risks of removing a normal meniscus far exceed those of leaving a tear in the posterior third. Statistical analysis of clinical features revealed no reliable diagnostic pattern

In a longitudinal case-control study, we followed 81 subjects with dysplasia of the hip and 136 control subjects without dysplasia for ten years assessing radiological evidence of degeneration of the hip at admission and follow-up. There were no cases of subluxation in the group with dysplasia. Neither subjects with dysplasia nor controls had radiological signs of ongoing degenerative disease at admission. The primary radiological discriminator of degeneration of the hip was a change in the minimum joint space width over time. There were no significant differences between these with dysplasia and controls in regard to age, body mass index or occupational exposure to daily repeated lifting at admission. We found no significant differences in the reduction of the joint space width at follow-up between subjects with dysplasia and the control subjects nor in self-reported pain in the hip. The association of subluxation and/or associated acetabular labral tears with dysplasia of the hip may be a conditional factor for the development of premature osteoarthritis in mildly to moderately dysplastic hips

We compared time-dependent changes in the biomechanical properties of single-and double-row repair of a simulated acute tear of the rotator cuff in rabbits to determine the effect of the fixation techniques on the healing process. A tear of the supraspinatus tendon was created in 80 rabbits which were separated into two equal groups. A single-row repair with two suture anchors was conducted in group 1 and a double-row repair with four suture anchors in group 2. A total of ten intact contralateral shoulder joints was used as a control group. Biomechanical testing was performed immediately post-operatively and at four and eight weeks, and histological analysis at four and eight weeks. The mean load to failure in group 2 animals was greater than in group 1, but both groups remained lower than the control group at all intervals. Histological analysis showed similar healing properties at four and eight weeks in both groups, but a significantly larger number of healed tendon-bone interfaces were identified in group 2 than in group 1 at eight weeks (p < 0.012). The ultimate load to failure increased with the number of suture anchors used immediately post-operatively, and at four and eight weeks. The increased load to failure at eight weeks seemed to be related to the increase in the surface area of healed tendon-to-bone in the double-row repair group

Aims

We aimed to address the question on whether there is a place for shoulder stabilization surgery in patients who had voluntary posterior instability starting in childhood and adolescence, and later becoming involuntary and uncontrollable.

From a total of 1571 surgically excised menisci, 112 (7.1 per cent) were found by gross and microscopic examination to contain one or more cysts. All of these cysts were associated with tears, either primarily horizontal or with a horizontal component. Tracks were often demonstrable leading from the tear to the cysts, and in some cases of osteoarthritis, detritus of bone could be found in their periphery. It is concluded that the cysts are fuelled by synovial fluid. The relationship of cysts to "myxoid" change of the meniscus is discussed

Twenty-two patients with cysts of the lateral meniscus have been treated by operation. A modified operative procedure is described whereby the meniscus is inspected for a concomitant tear. A tear of the meniscus was found in ten patients and these were treated by meniscectomy. The remaining twelve cases were treated by excision of the cyst only. The rehabilitation period was considerably less in these patients. Recurrence of the cyst did not occur. The rationale for local excision is based on the similarity between the cyst of a meniscus and a simple ganglion, and also on the desirability of preserving the meniscus

We reviewed 44 patients with 44 full-thickness rotator-cuff tears at an average of 4.2 years after arthroscopically-assisted repair. There were 25 women and 19 men aged between 35 and 76 years (average 58); 35% of the shoulders had other intra-articular lesions. Most of the patients (85%) had been discharged from hospital immediately after the operation. The result was rated good or excellent in 84%, 88% of the patients were satisfied, and 64% of the athletes returned to their previous sports. The size of the tear was a determining factor in the outcome

1. Strain or rupture of the anterior marginal attachments of the meniscus was observed in approximately 10 per cent of a group of patients operated upon for internal derangement. 2. In about half of these a tear of the body of the meniscus was found and it is probable that this tear may have been the cause of the symptoms. In the remainder no injury to the body of the meniscus was found. 3. Recognition may be difficult and delay in diagnosis may be the cause of degenerative joint changes. 4. The condition should be looked for at operation when the meniscus appears to be intact or when the only lesion appears to be an area of chondromalacia on the weight-bearing surface of the femoral condyle

Among 41 adult haemophiliacs 15 suffered from shoulder symptoms. We examined 12 patients by radiography and ultrasound. Four had bilateral symptoms making a total of 16 symptomatic shoulders. Of these, 10 had abnormal ultrasound scans with eight having evidence of rotator cuff tears. Evidence of bicipital tendonitis was found in two. Pain with loss of range of movement and a positive impingement sign was the most reliable clinical indicator of a cuff tear. Joint incongruity and superior migration of the humeral head were the best radiographic indicators. Rotator cuff tears are a common component of haemophilic arthropathy of the shoulder
