1. The results are recorded of radical excisional surgery for spinal tuberculosis in eighty-five patients. 2. Clinically satisfactory results were obtained in 97 per cent of seventy-one patients followed up. Radiologically the disease was deemed to be cured in 71 per cent of cases. 3. The average period of rest after operation was three and a half months, and the average hospital stay was five and a half months. 4. Total recovery from paraplegia occurred in 84 per cent of patients so affected

1. Three new cases of neonatal sciatic palsy are reported in twins. They received identical treatment after birth; in the case of the first two for identical difficulties occurring after delivery. In twins there is a greater liability to neonatal shock and so a greater incidence of umbilical injections. 2. The clinical evidence and the necropsy findings in Case 3 support the hypothesis that intra-arterial thrombosis is caused by the injection of an analeptic into the umbilical artery. 3. The clinical picture is described, with a discussion on the pathology, treatment and the reason for recovery in some cases

We reviewed a series of 79 distal radial fractures with volar displacement which had been fixed internally using a buttress plate. The fractures were classified using the Frykman and AO systems; 59% were intraarticular. Complications occurred in 40.5% of cases; malunion was most frequent (28%). Functional recovery in patients with malunion was significantly worse than in those with good anatomical restoration (p < 0.001). The AO and Frykman classifications and the degree of restoration of volar tilt were predictive of outcome

Aims

The aim of this study was to evaluate the efficacy of the surgical dislocation approach and modified trapdoor procedure for the treatment of chondroblastoma of the femoral head.

We report the case of a 59-year-old man with severe knee pain and inability to flex his toes or invert his plantar flexed foot after an external rotation injury to his knee. MRI showed rupture of the popliteus with a haematoma compressing the neurovascular bundle in the proximal calf, and electromyography demonstrated signs of an axonotmesis of the posterior tibial nerve. There was progressive nerve recovery over 24 weeks. Isolated rupture of the popliteus should be considered in any patient with an acute haemarthrosis, lateral tenderness and a stable knee, especially after an external rotation injury

We report 13 patients with missed bilateral facet dislocation of the lower cervical spine who subsequently developed severe spinal-cord involvement. There were more women and the patients were older than in most groups with spinal injury. The commonest cause was a fall, and paralysis appeared from six to 48 hours after injury in most patients. Ten patients made some recovery after late reduction but three remained totally paralysed. We discuss the pathogenesis of the late cord lesion and the reasons for delay in diagnosis

Fractures of the femur are the most incapacitating fractures in children. Conservative treatment necessitates a long stay in hospital for traction and subsequent immobilisation in an uncomfortable cast. This treatment is not well tolerated, especially in adolescents. Moreover, near the end of growth, accurate reduction is necessary, as malunion is no longer correctable by growth. Stable elastic intramedullary nailing uses two flexible nails which are introduced percutaneously either through the lower metaphysis or the subtrochanteric area. This technique does not disturb the healing of the fracture. The elasticity of the device allows slight movement at the fracture site which favours union. Reduction and stabilisation are adequate and the operative risk is very low. A cast is not required, functional recovery is rapid and the patient is allowed to walk with crutches after seven to ten days according to the type of fracture. This technique is very efficient in adolescents and can be used after the age of seven years when conservative treatment is unsuccessful

Intramedullary spinal cord tumours may present as scoliosis without neurological signs. Those treating spinal deformities should be alert to this possible aetiology. The clinical features of 12 such cases are discussed with reference to early diagnosis and treatment. Patients with a painful scoliosis should be investigated with myelography as well as bone scintigraphy. Many intrinsic spinal cord tumours are now amenable to surgical removal. The prognosis for neurological recovery is poor once a severe deficit becomes established. The importance of early diagnosis and joint orthopaedic and neurosurgical management is emphasised

A comparative study of methods for treating fractures of the distal half of the femur was carried out prospectively in the five-year period January 1973 to December 1977. The three methods compared were conservative treatment on a Thomas' splint, application of a knee-hinged cast-brace at five to seven weeks, and intramedullary nailing. The time in bed, in hospital and to union were compared as was the rate of functional recovery of the knee. It is concluded that the cast-brace provides a safe reliable method of treatment, combining the advantages of non-operative management with the early mobilisation possible with intramedullary fixation but without the disadvantages of surgical treatment

1. Sixty-one cases of compression of the ulnar nerve are reported, forty at the elbow and twenty-one at the wrist. Although contributory factors may include deformity, osteoarthritis, injury, ganglia and other tumours, the narrow anatomical confines of the nerve at these two levels are noteworthy and alone may produce nerve compression. 2. Careful clinical examination will usually determine the level of involvement if not the exact pathology. Surgical exploration is indicated both as a diagnostic and therapeutic procedure in most cases. 3. Following removal of the compressing agent rapid recovery occurred in most cases

Over a period of twenty years a small number of patients, thirty-one, have been seen who suffered injuries of the infraclavicular brachial plexus as a direct result of skeletal injury in the region of the shoulder joint. Except for isolated circumflex nerve injuries the prognosis is generally good whatever part of the plexus is damaged. The treatment is conservative and its two most important features are prevention of stiffness of joints and the control, by regular galvanic stimulation, of denervation atrophy of muscle during the often prolonged period before recovery becomes apparent

1. A case of fracture-dislocation of the atlas on the axis is presented in which the neck had been manipulated under anaesthesia for "rheumatism.". 2. Despite marked displacement there were no important neurological complications. 3. One-stage reduction by traction was carried out very slowly and with radiographic control. It is believed that this is less distressing to the patient, and safer, than gradual reduction by prolonged traction. 4. Because of the instability of the atlanto-axial joint after reduction surgical fusion of the upper cervical spine to the occipital bone is advisable. 5. In the case now reported recovery was complete

In a series of 1304 patients (1867 knees), the results of simultaneous and staged bilateral total knee arthroplasty were compared with each other and with unilateral total knee arthroplasty. The bilateral procedures had a significantly higher rate of complications than unilateral procedures, almost entirely because of thromboembolic problems. However, this did not correspond to an increase in mortality. If a bilateral procedure was indicated, then a simultaneous procedure had no increased risk over a staged procedure. There was no increase in cardiovascular complications, the rate of deep-vein thrombosis or pulmonary embolism or mortality. The rate of infection was lower with a bilateral procedure and the overall revision rate was less than 1% in all groups. The prosthesis functioned as well in all groups in the medium and longer term periods. We feel that simultaneous bilateral total knee arthroplasty is a safe and successful procedure when compared with a staged bilateral procedure. It also has the added benefit of single anaesthetic, reduced costs and decreased total recovery time when compared to a staged bilateral procedure. For these reasons it should be considered as an option in the presence of bilateral knee joint disease

Of 64 patients with stab wounds involving the brachial plexus operated on by one surgeon, 18 were followed up in detail, with a view to reviewing operative techniques, results and the lessons to be learned. Primary nerve grafting produced better results than end-to-end repair, even in fresh cases. The recognition of nerve compression by a false aneurysm is important, since in these cases, vascular repair alone may not give recovery and neurolysis may be necessary. The overall results of operation were good; lesions of C5 and C6 roots recovered better than those of more distal roots

This paper reports a prospective study of 72 consecutive patients with fractures or fracture-dislocations of the upper end of the humerus, treated during 1981. Most were elderly and treatment was conservative. Of the 72 patients 64 were followed up for a period of six months. Observations were made on the type of fracture, the speed and pattern of recovery of shoulder movements, on the time of commencement of physiotherapy, and on its duration. We found that with conservative treatment alone, 94% of our patients had good or satisfactory results at six months from injury. The criteria for manipulation are discussed and the literature is reviewed

1. Forty-five cases of zoster paralysis, not involving the cranial nerves, are detailed. These include eighteen cases not previously published. Of these eighteen patients, one-third were referred for an orthopaedic opinion. 2. Complete or almost full recovery occurred within a year in two-thirds of the patients. Permanent paralysis occurred in one-sixth of the patients studied. 3. Muscles that failed to recover were mainly or wholly supplied from single segments of the spinal cord; so the prognosis must be guarded in those cases in which such muscles are completely paralysed. 4. Various phenomena occurring in zoster paralysis are discussed

1. Evidence is presented that certain types of cervical spine injury are due mainly to lateral flexion forces. 2. These injuries are often complicated by a brachial plexus lesion as well as a lesion of the spinal cord. 3. It is not always easy to detect the brachial plexus injury when the patient is first seen. 4. In the cases reviewed there has been little or no recovery of cord function, and the existence of a brachial plexus injury has, of course, made rehabilitation much more difficult. 5. The practical importance of recognising the mechanism of this type of injury is that treatment which will cause further separation of the vertebrae is inadvisable

Aims

Revision total knee arthroplasty (rTKA) accounts for approximately 5% to 10% of all TKAs. Although the complexity of these procedures is well recognized, few investigators have evaluated the cost and value-added with the implementation of a dedicated revision arthroplasty service. The aim of the present study is to compare and contrast surgeon productivity in several differing models of activity.

Aims

Custom flange acetabular components (CFACs) are a patient-specific option for addressing large acetabular defects at revision total hip arthroplasty (THA), but patient and implant characteristics that affect survivorship remain unknown. This study aimed to identify patient and design factors related to survivorship.
