Patients with spina bifida cystica commonly have significant disability from a combination of valgus deformity of the ankle and subtalar joints with lateral tibial torsion and plano-abduction deformity of the foot. These deformities can be corrected by a single procedure which combines a supramalleolar tibial osteotomy with a lateral inlay triple fusion. This procedure was carried out on 20 feet in 15 patients and the results were reviewed after an average of three years (range 18 months to 7 years). In 75 per cent of feet the combination of deformities was fully corrected, ulcers and callosities were eliminated in 95 per cent, the use of calipers minimised in 95 per cent, and in all patients the problem of shoe-wrecking was reduced. Complications included recurrent valgus deformity, delayed union of the tibial osteotomy and failure of midtarsal fusion

The costo-clavicular ligament is always ruptured in dislocation at the sterno-clavicular joint. Anterior, superior or posterior displacement of the medial end of the clavicle may occur. Acute dislocation usually responds to conservative treatment and operation is seldom required. Chronic, or recurrent, dislocation may cause pain and disability on strenuous activity and necessitate surgical treatment. The operation of tenodesis of the subclavius tendon with capsulorrhaphy described by Burrows (1951) has been adopted. The intraarticular meniscus is often damaged and displaced, and may block reduction; its removal is then necessary. In addition, a threaded Steinmann pin transfixing the joint has been found useful to maintain the stability of reduction. The operation has been performed on five patients, four of whom had excellent results. The fifth patient disrupted the repair in a drinking bout shortly after the operation

1. The technique of the intra-articular surgery employed by the late Mr K. H. Pridie for osteoarthritis of the knee is described. 2. The results of sixty-two operations in sixty patients are analysed. The results in forty-eight knees (77 per cent) were pleasing to the patient. Forty knees (64 per cent) were rated as good at review. 3. The operation is most suitable for relatively active healthy people whose disability warrants a comparatively painful operation and lengthy rehabilitation. 4. The operation was most successful for relieving pain and improving stability. Functional improvement was less. 5. Results were remarkably permanent. The knees showed little tendency towards further deterioration. 6. Most of the bad results were associated with removal of the patella. A possible technical reason for this has been discussed

We reviewed retrospectively 45 patients (46 procedures) with bladder exstrophy treated by bilateral oblique pelvic osteotomy in conjunction with genitourinary repair. The operative technique and post-operative management with or without external fixation are described. A total of 21 patients attended a special follow-up clinic and 24 were interviewed by telephone. The mean follow-up time was 57 months (24 to 108). Of the 45 patients, 42 reported no pain or functional disability, although six had a waddling gait and two had marked external rotation of the hip. Complications included three cases of infection and loosening of the external fixator requiring early removal with no deleterious effect. Mid-line closure failed in one neonate managed in plaster. This patient underwent a successful revision procedure several months later using repeat osteotomies and external fixation. The percentage pubic approximation was measured on anteroposterior radiographs pre-operatively, post-operatively and at final follow-up. The mean approximation was 37% (12% to 76%). It varied markedly with age and was better when external fixation was used. The wide range reflects the inability of the anterior segment to develop naturally in spite of close approximation at operation. We conclude that bilateral oblique pelvic osteotomy with or without external fixation is useful in the management of difficult primary closure in bladder exstrophy, failed primary closure and secondary reconstruction

Aims

The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches

We reviewed 46 leg-shortening operations (37 femoral and nine tibial), performed by different methods, to assess the incidence of complications and permanent disability. Shortening of as much as 7.5 cm in the femur and 5 cm in the tibia was achieved in men of normal height without any loss of function. Complications were seen with all surgical techniques despite the use of modern implants. Most problems arose from inadequate stabilisation of the osteotomy. The most reliable method of femoral shortening was open subtrochanteric osteotomy with preservation of the isthmus, and fixation with an intramedullary nail locked at its proximal end. In tibial shortening, bone excision should be at the level of the flare in the lower diaphysis in order to achieve reliable bone healing. Simple intramedullary nail fixation should be supplemented with a long-leg cast for six weeks or the nail should be locked at both ends to prevent postoperative distraction or rotation

Aims

The purpose of this retrospective study was to investigate the clinical relevance of increased facet joint distraction as a result of anterior cervical decompression and fusion (ACDF) for trauma.

The thalamus is the part of the calcaneus that supports the posterior articular facet and continues forward, becoming thinner towards the groove of the sinus tarsi. The main displacements after fracture depend on 1) a primary fracture line dividing the bone into anterior and posterior fragments, and 2) a semilunar fragment in the thalamic region. In the operation advised the sinus tarsi is exposed and the semilunar fragment is reduced by rotation in the opposite direction and is fixed to the medial fragment (the sustenaculum tali not being displaced) by a transverse Kirschner wire. The two main fragments are fixed by an antero-posterior wire. Plaster is applied and is retained for twelve weeks. Weight-bearing is not permitted for the first four weeks. There were no major complications in fifty-eight operations. The anatomical results were good: restoration of the tuber-joint angle by reduction of the semilunar fragment was maintained. The functional results were very satisfactory: permanent disability was slight or mild

Everywhere I visited, both in England and in other parts of Europe, I met with wonderful hospitality and friendliness. Generally our common language was English, and I felt thoroughly ashamed of my poor efforts at speaking other languages. During my tour in England, France, Germany, Austria, Italy, Denmark, Norway and Sweden I heard many new ideas propounded, and have seen many new and different methods of treatment. In particular I have been able to compare thoughts on such subjects as tuberculosis of the spine, congenital dislocation of the hip, osteoarthritis of the hip, scoliosis, many aspects of trauma, Perthes' disease, hand surgery, poliomyelitis, paraplegia, the treatment of cerebral palsy, rehabilitation of patients suffering from all kinds of orthopaedic disabilities, and surgical appliances. I am very grateful indeed to the British Orthopaedic Association for making this six-months' tour possible

1. A study of the late results of 343 soundly united tibial shaft fractures was carried out. Limitation of ankle and/or foot movement occurred in twenty-one patients (6 per cent) and was found to be the most important cause of disability. Knee stiffness (2·3 per cent of cases) and shortening of up to three-quarters of an inch (5·5 per cent of cases) caused little functional impairment. 2. Stiffness of the foot and ankle was correlated with the severity of injury, occurring in 1 per cent of minor, 5 per cent of moderate and 22 per cent of major injuries. 3. One-third of the patients with limitation of foot and ankle movement had clinical evidence of ischaemic contracture. 4. It is argued that, in the absence of direct injury to the joint, persistent joint stiffness is caused by replacement fibrosis of soft tissues. This may result either from direct tissue injury or from associated vascular damage

A vascular necrosis of the lunate, first described by Kienböck, can be treated either conservatively or by various surgical procedures. We compared the results of 18 conservatively treated patients, all of whom had stage-2 or stage-3 disease, with those of 15 who underwent a radial shortening procedure. We evaluated pain, range of movement, grip strength and functional disability, and determined the progression of the disease by assessing radiologically carpal height, the width and flattening of the lunate, the radioscaphoid angle, the pattern of the fracture and sclerosis and cysts. The mean follow-up was for 3.6 years (1.5 to 9). Patients treated by radial shortening had less pain and better grip strength than those managed conservatively. In some patients with stage-3 disease treated conservatively there was rapid deterioration to carpal collapse. Although radial shortening did not reverse or prevent carpal collapse, it slowed down the process in patients with stage-3 disease. We recommend a radial shortening procedure for patients with severe pain and radiological signs of progressive carpal collapse

A subjective, objective and radiographic study of 21 patients with comminuted calcaneal fractures showing severe involvement of the subtalar joint is reported. The average follow-up was 14.6 years (range 8 to 29 years). Only patients with unilateral closed fractures and no associated injuries to either lower limb were admitted to the study. All were treated by early active mobilisation of the ankle, and the subtalar and the midtarsal joints. Seventy-six per cent of the patients achieved a good result with minor symptoms which did not interfere with their occupation or leisure requirements. Although two-thirds of the patients reached a point of maximal recovery at two to three years, 24% continued to improve for six years. None of the patients experienced any deterioration after this time. Neither the degree of clinical stiffness nor the degeneration of the subtalar joint, assessed radiographically, correlated with the severity of symptoms or functional disability. The role of the soft tissues in the aetiology of residual symptoms is discussed

1. A new procedure, called "the extensor diversion graft operation", has been devised for correcting the deformity and reducing the disability of the intrinsic minus fingers so commonly seen in leprosy. 2. The procedure consists of the insertion of a free tendon graft which spans the metacarpophalangeal joint along its volar aspect and is attached at both ends to the extensor mechanism, to the extensor tendon proximally and to the lateral band distally. 3. The procedure reduces extensor dominance at the metacarpo-phalangeal joint and improves the balance of forces, allowing the assumption of a straight posture by use of the extrinsic muscles. 4. The assessment of function of ninety-seven fingers on average eight months after operation has shown that in addition to correction of deformity, this procedure in the majority of cases also restores partial independence of movement at the metacarpo-phalangeal and proximal interphalangeal joints, to such an extent that the finger can reach and hold a functionally useful position. 5. One advantage of the procedure is that it obviates the need for re-education of muscles

1. The results of arthroplasty of the forefoot in thirty-eight patients with polyarthritis have been analysed in detail. Sixty-five feet had been operated on by one of three different techniques–Kates-Kessel-Kay, Fowler or Clayton–though sometimes with modifications. 2. The subjective results were remarkably good. The patients were completely satisfied with forty-two operations, satisfied in most respects with twenty-one, and dissatisfied with only two. 3. The commonest cause of persistent pain was prominence of one metatarsal stump; great care must be taken at the time of operation to ensure that the metatarsals are trimmed to equal length. 4. The objective results were less satisfactory. The lateral four toes were usually functionless, the gait was never normal and the walking distance was still restricted, though often by other factors. The operation, therefore, should be carried out only in patients with severe pain and disability. 5. A comparison of the results of the three different techniques of operation showed no major differences

1. The rate of non-union of 100 intertrochanteric osteotomies of the McMurray type, with internal fixation, is reported. One in five was not united one year after operation. The criteria of union are discussed. 2. The patient's disability in twelve ununited osteotomies has been assessed, and related to the mobility of the osteotomy. 3. The factors which prejudice union have been analysed. The principal cause of non-union appeared to be the varus angulation strain on a varus osteotomy displaced medially more than half the diameter of the bone. Obliquity inwards and upwards of the osteotomy was a contributory factor. The types of internal fixation used, the use of external splintage and the period of protected weight bearing with crutches did not appear to be related to the rate of union. 4. It is concluded that marked inward displacement of the osteotomy, combined with either obliquity of the osteotomy or a varus position, prejudices union; that the use of this technique is unfounded in principle and not supported empirically; and that displacement should be eschewed to avoid this complication of intertrochanteric osteotomy in the treatment of osteoarthritis of the hip

Spinal accessory nerve palsy leads to painful disability of the shoulder, carrying an uncertain prognosis. We reviewed the long-term outcome in 16 patients who were treated for pain, weakness of active elevation and asymmetry of the shoulder and the neck due to chronic paralysis of the trapezius muscle, as a result of nerve palsy. Of four patients who were treated conservatively, none regained satisfactory function, although two became pain-free. The other 12 patients were treated operatively with transfer of the levator scapulae to the acromion and the rhomboid muscles to the infraspinatus fossa (the Eden-Lange procedure). At a mean follow-up of 32 years, the clinical outcome of the operatively treated patients was excellent in nine, fair in two, and poor in one patient, as determined by the Constant score. Pain was adequately relieved in 11 and overhead function was restored in nine patients. Pre-operative electromyography had been carried out in four patients. In two, who eventually had a poor outcome, a concomitant long thoracic and dorsal scapular nerve lesion had been present. The Eden-Lange procedure gives very satisfactory long-term results for the treatment of isolated paralysis of trapezius. In the presence of an additional serratus anterior palsy or weak rhomboid muscles, the procedure is less successful in restoring shoulder function

Total hip and total knee arthroplasty both provide a considerable improvement in quality of life, but there is no evidence to suggest that one is more successful than the other. We studied 72 patients in a prospective trial before and after total hip or total knee replacement. We recorded scores for disability and distress derived from the Harris hip score and the British Orthopaedic Association knee assessment score, and used them to generate quality of life (QoL) scores using the Rosser Index Matrix immediately before and at one year after surgery. The patients awaiting knee replacement had significantly lower QoL scores than those awaiting hip replacement (p = 0.011). The QoL scores at one year were high and almost identical for both groups (p = 0.46). Further analysis showed that gender and weight were not significant predictors of improvement of QoL scores, but age (p = 0.03) and whether the hip or knee was replaced (p = 0.006) were significant factors

We retrospectively reviewed 56 patients (71 hips) treated by total replacement for severe disability after pelvic irradiation. Symptoms were associated with various radiological lesions due to irradiation, including atraumatic femoral-neck fracture, osteonecrosis of the femoral head or of the acetabulum, and radiation osteitis of the whole pelvis. From 1970 to 1982 we used standard cemented components in 49 hips and had a high rate of acetabular loosening (52%) at a mean follow-up of 69 months. This was probably due to the mechanical insufficiency of irradiated periacetabular bone. From 1983 to 1990 we routinely used acetabular reinforcement rings. The rate of aseptic acetabular loosening in 22 hips at a mean follow-up of 40 months was 19%, but there were two septic loosenings emphasising the risk of infection in these patients. When total replacement is required for an irradiated hip, we recommend reinforcement of the acetabulum using a metallic ring, but there is still an increased risk of infection and in difficult cases such as severe acetabular destruction or soft-tissue or vascular injuries, a Girdlestone procedure may be indicated
