Aims

The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires.

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

Seven patients with stress fractures of the femoral neck were treated at the Military Hospital of Thessaloniki, Greece between 1972 and 1976. Their average age was 22 years. Stress fractures of the femoral neck are not as common as stress fractures of the metatarsals or tibia and other bones. Intense muscular activity was the main cause of these stress fractures which were only classed as such in the absence of any injury. Pain and stiffness around the hip were reported by all seven patients before admission. Results of laboratory investigations of the patients' alkaline phosphatase and serum calcium levels were normal. One patient received surgical treatment and the other patients were treated conservatively. Healing was uneventful in all

1. The pedigree of a family in which lobster claw foot and triphalangeal thumb occurred together is presented. The affected members of two generations are described. The clinical appearances and radiological abnormalities are described in detail. Results of surgical treatment of the forefoot cleft are presented. 2. Lobster clawing of the foot is discussed with particular reference to associated hand and finger abnormalities. Triphalangeal thumb is discussed. The current and probably acceptable theory of the etiology of duplication is expanded. A hypothesis is formulated of excessive activity at the pre-and post-axial borders of the distal limb bud, followed by variable resorption, to explain not only the cause of lobster claw foot but also its occurrence in association with triphalangeal thumb

We describe a new operative procedure for patients with chronic trochanteric bursitis. Between March 1994 and May 2000, a trochanteric reduction osteotomy was performed on ten patients (12 hips). All had received conservative treatment for at least one year. Previous surgical treatment with a longitudinal release of the iliotibial band combined with excision of the trochanteric bursa had been performed on five hips. None had responded to these treatments. The mean follow-up was 23.5 months (6 to 77). The mean Merle d’Aubigné and Postel score improved from 15.8 (8 to 20) before to 27.5 (18 to 30) after operation, six patients showing very great improvement, five great improvement and one fair improvement. We conclude that trochanteric reduction osteotomy is a safe and effective procedure for patients with refractory trochanteric bursitis who do not respond to conservative treatment

Limited access surgery is thought to reduce post-operative morbidity and provide faster recovery of function. The percutaneous compression plate (PCCP) is a recently introduced device for the fixation of intertrochanteric fractures with minimal exposure. It has several potential mechanical advantages over the conventional compression hip screw (CHS). Our aim in this prospective, randomised, controlled study was to compare the outcome of patients operated on using these two devices. We randomised 104 patients with intertrochanteric fractures (AO/OTA 31.A1–A2) to surgical treatment with either the PCCP or CHS and followed them for one year postoperatively. The mean operating blood loss was 161.0 ml (8 to 450) in the PCCP group and 374.0 ml (11 to 980) in the CHS group (Student’s t-test, p < 0.0001). The pain score and ability to bear weight were significantly better in the PCCP group at six weeks post-operatively. Analysis of the radiographs in a proportion of the patients revealed a reduced amount of medial displacement in the PCCP group (two patients, 4%) compared with the CHS group (10 patients, 18.9%); Fisher’s exact test, p < 0.02. The PCCP device was associated with reduced intra-operative blood loss, less postoperative pain and a reduced incidence of collapse of the fracture

From 1975 to 1988, operative treatment was performed on 50 feet in 45 patients with tarsal tunnel syndrome. The causes of this syndrome were correlated with operative findings and included ganglia in 18, and a bony prominence from talocalcaneal coalition in 15. Five feet had sustained an injury, tumours were found in three and there was no obvious cause in nine. In most cases in need of operative treatment, there was a space-occupying lesion. Classifying the results according to causes, those with coalition or a tumour fared better, and idiopathic and traumatic cases had a worse outcome. In cases with a definite lesion, an excellent result can be expected from surgical treatment carried out soon after onset of the condition

Aims

Options for the treatment of intra-articular ligament injuries are limited, and insufficient ligament reconstruction can cause painful joint instability, loss of function, and progressive development of degenerative arthritis. This study aimed to assess the capability of a biologically enhanced matrix material for ligament reconstruction to withstand tensile forces within the joint and enhance ligament regeneration needed to regain joint function.

Aims

We compared implant and patient survival following intraoperative periprosthetic femoral fractures (IOPFFs) during primary total hip arthroplasty (THA) with matched controls.

Aims

Aseptic loosening is a major cause of failure in cemented endoprosthetic reconstructions. This paper presents the long-term outcomes of a custom-designed cross-pin fixation construct designed to minimize rotational stress and subsequent aseptic loosening in selected patients. The paper will also examine the long-term survivorship and modes of failure when using this technique.

Of a consecutive series of 117 one-year-old infants with 130 established dislocations of the hip, 11% failed to respond to primary surgical treatment. Genetic and iatrogenic factors accounted for half the failures. There were no obvious causes in the remainder, though a few had the superficial stigmata of spinal dysraphism, and by two years of age, most of the group had developed a lateral rotation posture of the affected leg associated with a relatively smaller foot on that side. Radiologically, the femoral head had drifted and rotated laterally out of the surgically deepened acetabulum, causing persistent subluxation. Although there was no clinical evidence of sensory or motor denervation, sensory spinal evoked potential tests revealed the presence of neurological deficits in the majority of patients in this group

Experience in the management of fourteen children with melorheostosis has been reviewed. The principal and presenting clinical features were unilateral soft-tissue contractures associated with inequality of limb length. In contrast to the disease in adults, pain occurred infrequently and was never intense. The average interval between the discovery of the clinical features and the correct diagnosis was six years. The distinctive radiographic feature in the child was an endosteal pattern of hyperostosis marked by streakiness of the long bones and spotting of the small. This differs from the usual subperiosteal or extracortical pattern of hyperostosis seen in adults. The surgical treatment of the contractures proved difficult and recurrence of the deformity was the rule. Distal ischaemia occurred when the chronically contracted and flexed joint was rapidly extended

Immobility has been used as an indication for conservative treatment of patients with fractures of the hip, although there is little in the literature to support this view. We conducted a prospective review of 3515 patients with hip fractures of whom 152 (4.3%) were immobile prior to the fracture. Nine patients were treated conservatively, the rest by operation. The mean age was 83 years (42 to 99); the mean length of hospital stay was 17.8 days; 19 patients (12.5%) died whilst still in hospital and 120 (79.0%) went back to their original residence. There were 38 post-operative complications. At one year after injury, 73 patients were still alive. Of the survivors, 54 (74.0%) had none or minimal pain in the hip and 58 (79.5%) had the same residential status as before the fracture. Immobility in patients with hip fracture is uncommon and is not a valid reason for withholding surgical treatment

Aims

There is an increasing demand for hip arthroplasty in China. We aimed to describe trends in in-hospital mortality after this procedure in China and to examine the potential risk factors.

We describe a prospective study of 328 patients undergoing arthroscopy of the hip. Arthrography, CT or MRI was performed when clinically indicated. A preoperative diagnosis was reached in 174 patients (53%), while the remaining 154 were diagnosed as having ‘idiopathic hip pain’. In seven patients, access to the hip was inadequate. Arthroscopy altered the diagnosis in 176 hips (53%). The new primary diagnoses were osteoarthritis (75 patients), osteochondral defects (34), torn labra (23), synovitis (11) and loose bodies (9). In 172 hips (52%) an operative procedure was undertaken. In the remaining 84 patients (26%), arthroscopy neither changed the diagnosis nor provided surgical treatment. Arthroscopy of the hip is considered to be of value in assessing and treating the adult patient with pain in the hip of uncertain cause

The surgical treatment of Perthes’ disease by femoral or innominate osteotomy is not as effective in those over the age of eight years as it is in the younger child. This has prompted the search for other types of management in those who are older. The preliminary results of the use of a lateral shelf acetabuloplasty for such cases have shown encouraging results at two years. The concern with such an operation is that it might interfere with the growth of the outer aspect of the acetabulum and so prejudice the long-term outcome. We describe a review at maturity of 26 children presenting with early disease after the age of eight years who were treated by lateral shelf acetabuloplasty. The results suggest that the outcome is improved; 22 of 27 hips were rated as Stulberg groups 1 to 3. Poor results occurred in children, particularly girls, presenting with Group-4 disease over the age of 11 years

We treated 26 patients with 27 aneurysmal bone cysts by curettage and cryotherapy and evaluated local tumour control, complications and functional outcome. The mean follow-up time was 47 months (19 to154). There was local recurrence in one patient. Two patients developed deep wound infections and one had a postoperative fracture. We compared our results with previous reports in which several different methods of treatment had been used and concluded that curettage with adjuvant cryotherapy had similar results to those of marginal resection, and that no major bony reconstruction was required. We recommend the use of cryotherapy as an adjuvant to the surgical treatment of aneurysmal bone cysts. It provides local tumour control. Combination with bone grafting achieved consolidation of the lesion in all our patients

A study of the natural history and aetiology of deep vein thrombosis in 499 patients after total hip replacement is presented. Deep vein thrombosis was diagnosed by scanning the leg for 125Iodine-labelled fibrinogen for a period of 14 to 18 days and by ascending phlebography. It has been shown that deep vein thrombosis occurs ater than in patients who have undergone abdominal operations, and the risk period is longer. The peak of onset of thrombosis is on the fourth day after the hip replacement. Attempts at prophylaxis using subcutaneous heparin or intermittent pneumatic compression of the calves delay the appearance of thrombosis. Analysis of possible aetiology factors shows that the age of the patient, the degenerative disease of the hip, the surgical approach, and under-transfusion of blood, all have a significant effect on the incidence of thrombosis

Heterotopic ossification which may develop around the elbow in patients with burns may lead to severe functional impairment. We describe the outcome of early excision of such heterotopic ossification in 28 patients (35 elbows), undertaken as soon as the patient’s general and local condition allowed. The mean age at operation was 42 years. The mean area of burnt body surface was 49%. The mean pre-operative range of movement was 22° in flexion/extension and 94° in pronation/supination. The mean time between the burn and operation was 12 months with the median being 9.5. The mean follow-up period was for 21 months. At the last review, the mean range of movement was 123° in flexion/extension and 160° in pronation/supination. Clinical evidence of recurrence was seen in four patients, occurring within the first two months after operation. Nevertheless, three of these elbows gained 60° or more in flexion/extension and in pronation/supination. Based on this experience, we recommend early surgical treatment of heterotopic ossification of the elbow in patients with severe burns
