1 . A new surgical approach to the treatment of pes cavus is suggested. The operation consists in a subcutaneous division of the contracted plantar fascia and correction of the varus deformity of the heel by removing a wedge from its lateral aspect. It is submitted that, by approaching the deformity from behind and overcoming the varus of the heel, the foot is rendered plantigrade and that thereafter weight bearing exerts a corrective influence which results in progressive improvement of the deformity. The operation is essentially a prophylactic one and, for the best results, it should be performed before there is gross structural deformity and while active growth is still taking place. 2. Even in patients over the age of fourteen, improvement is obtained by doing nothing more than this simple operation. In the presence of fixed deformity of the forefoot, as encountered in older patients, inversion is corrected by removing a lateral wedge from the calcaneum and the cavus by taking a dorsal wedge from the tarso-metatarsal region. This has the double advantage of producing good correction of deformity, while at the same time preserving movement at the mid-tarsal-subtalar joint. Fixed clawing of the toes will require appropriate corrective treatment, but if the toes are malleable the simple effect of weight bearing on the plantigrade foot produces gradual correction

Aims

Delayed diagnosis is a well-known complication of a Monteggia fracture-dislocation. If left untreated, the dislocated radial head later becomes symptomatic. The purposes of this study were firstly, to evaluate the clinical and radiological results of open reduction of the radial head and secondly, to identify the factors that may affect the outcome of this procedure.

Objectives

The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits.

Aims

The aim of this study was to describe temporal trends and survivorship of total hip arthroplasty (THA) in very young patients, aged ≤ 20 years.

Aims

Instability continues to be a troublesome complication after total hip arthroplasty (THA). Patient-related risk factors associated with a higher dislocation risk include the preoperative diagnosis, an age of 75 years or older, high body mass index (BMI), a history of alcohol abuse, and neurodegenerative diseases. The goal of this study was to assess the dislocation rate, radiographic outcomes, and complications of patients stratified as high-risk for dislocation who received a dual mobility (DM) bearing in a primary THA at a minimum follow-up of two years.

We have developed criteria to determine the appropriate indications for lumbar laminectomy, using the standard procedure developed at the RAND corporation and the University of California at Los Angeles (RAND-UCLA). A panel of five surgeons and four physicians individually assessed 1000 hypothetical cases of sciatica, back pain only, symptoms of spinal stenosis, spondylolisthesis, miscellaneous indications or the need for repeat laminectomy. For the first round each member of the panel used a scale ranging from 1 (extremely inappropriate) to 9 (extremely appropriate). After discussion and condensation of the results into three categories laminectomy was considered appropriate in 11% of the 1000 theoretical scenarios, equivocal in 26% and inappropriate in 63%. There was some variation between the six categories of malalignment, but full agreement in 64% of the hypothetical cases. We applied these criteria retrospectively to the records of 196 patients who had had surgical treatment for herniated discs in one Swiss University hospital. We found that 48% of the operations were for appropriate indications, 29% for equivocal reasons and that 23% were inappropriate. The RAND-UCLA method is a feasible, useful and coherent approach to the study of the indications for laminectomy and related procedures, providing a number of important insights. Our conclusions now require validation by carefully designed prospective clinical trials, such as those which are used for new medical techniques

We have reviewed 80 children who were involved in the Medical Research Council (UK) trial of surgical treatment for tuberculosis of the spine in Hong Kong. Radical surgery or debridement had been performed at mean ages of 7.6 years (n = 47) and 5.1 years (n = 33) respectively. The patients were followed up to skeletal maturity (mean 17 years). Spinal deformity was measured on lateral radiographs taken preoperatively, at six months, one year, five years and at final follow-up. Radical surgery and grafting produced a reduction in kyphos and deformity angles at six months; this correction was maintained during the growth period. By contrast, after debridement surgery there was an increase in deformity at six months, with a tendency to some spontaneous correction during the growth period. There were statistically significant differences between angles for the radical and debridement groups only at six months postoperatively, but the changes during later follow-up were similar in the radical and debridement groups. Our findings highlight the importance of the surgical correction of deformity, and provide no evidence to suggest that disproportionate posterior spinal growth contributes to progression of deformity after anterior spinal fusion in children

Aims

The aim of this study was to determine the efficacy of repeat epidural steroid injections as a form of treatment for patients with insufficiently controlled or recurrent radicular pain due to a lumbar or cervical disc herniation.

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.

The conventional osteotomies used to treat infantile tibia vara (Blount’s disease) may require internal fixation and its subsequent removal. These techniques, which carry the risk of traction injury, and potential problems of stability and consolidation, do not always succeed in correcting the rotational deformity which accompanies the angular deformity. We have used a new surgical approach, the serrated W/M osteotomy of the proximal tibia, to correct infantile tibia vara in 15 knees of 11 patients. We present the results in 13 knees of nine patients who have been followed up for a mean of eight years. The mean angular correction achieved after operation was 18 ± 5.8°. The mean femorotibial shaft angle was corrected from 14.2 ± 3.7° of varus to 4.6 ± 4.4° of valgus. At the last follow-up, the mean angular correction had reduced to 1.3 ± 4.9° of valgus without compromising the rotational correction and the overall good clinical results. All the patients and parents were satisfied, rating the result as excellent or good. There were no major postoperative complications and no reoperations. Eight patients were free from pain and able to perform physical activities suitable for their age. One complained of occasional pain. This procedure has the advantage of allowing both angular and rotational correction with a high degree of success without the need for internal fixation

Aims

This study aims to: determine the difference in pelvic position that occurs between surgery and radiographic, supine, postoperative assessment; examine how the difference in pelvic position influences subsequent component orientation; and establish whether differences in pelvic position, and thereafter component orientation, exist between total hip arthroplasties (THAs) performed in the supine versus the lateral decubitus positions.

A follow-up study, on average four years after operation, of seventy-six cildren with myelomeningocele who had surgical treatment for flexion contracture of the knee, is reported. After a single operation sixty-eight knees (55 per cent) had a contracture of less than 20 degrees, which was the main criterion of success. About half of the cases of transplantation of the hamstrings to the femur, division or elongation of the hamstrings, or supracondylar osteotomy had successful results. Transfer of the hamstring tendons to the patella was successful in nine of twelve instances, so giving the lowest rate of failure. Forty-five patients were active walkers at follow-up as compared to eighteen before operation. However, only one of the eleven patients over twelve years of age with a motor level above T.12 was an active walker at review. Several conclusions are drawn. A flexion contracture of the hip greater than 30 degress should be corrected before operation of the knee. Supracondylar osteotomy as a primary procedure should only be used to correct flexion contracture of the knee secondary to malunited fractures. Faradic stimulation is useful in the evaluation of muslce function before operation. An intelligence quotient below 65 and weakness of the arms are relative contraindications for correction of the deformity of the knee

Surgical decompression of the spinal canal is presently accepted worldwide as the method of treatment for thoracolumbar burst fractures with neurological deficit in the belief that neurological recovery may be produced or enhanced. Our clinical and laboratory experience, however, indicates that the paralysis occurs at the moment of injury and is not related to the position of the fragments of the fracture on subsequent imaging. Since the preoperative geometry of the fracture may be of no relevance, our hypothesis, backed by more than two decades of operative experience, is that alteration of the canal by ‘surgical clearance’ does not affect the neurological outcome. We have reviewed the existing world literature in an attempt to find evidence-based justification for the variety of surgical procedures used in the management of these fractures. We retrieved 275 publications on the management of burst fractures of which 60 met minimal inclusion criteria and were analysed more closely. Only three papers were prospective studies; the remainder were retrospective descriptive analyses. None of the 60 articles included control groups. The design of nine studies was sufficiently similar to allow pooling of their results, which failed to establish a significant advantage of surgical over non-surgical treatment as regards neurological improvement. Significant complications were reported in 75% of papers, including neurological deterioration. Surgical treatment for burst fracture in the belief that neurological improvement can be achieved is not justified, although surgery may still occasionally be indicated for structural reasons. This information should not be withheld from the patients

Aims

Surface replacement arthroplasty (SRA), compared with traditional total hip arthroplasty (THA), is more expensive and carries unique concern related to metal ions production and hypersensitivity. Additionally, SRA is a more demanding procedure with a decreased margin for error compared with THA. To justify its use, SRA must demonstrate comparable component survival and some clinical advantages. We therefore performed a systematic literature review to investigate the differences in complication rates, patient-reported outcomes, stress shielding, and hip biomechanics between SRA and THA.

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.

Low lumbar pain with radiation into the leg is a common symptom pattern caused by a number of pathological processes. Isolated disc resorption is one such entity which can be readily identified and is amenable to surgical treatment. This study consisted of two groups of patients. Group I were 50 patients suffering from isolated disc resorption at L5--S1 with ill-defined low backache extending into the buttocks and down one or both legs, but not into the feet. Clinical signs of nerve root dysfunction were found in 16 per cent of patients. Radiographic changes with loss of disc height, facet over-riding and intrusion into the nerve root canal and intervertebral foramen were common and frequently associated with sclerosis of the vertebral end-plate. Group II were a series of 45 patients with isolated disc resorption independently reviewed an average of 45 months after surgical decompression of the S1 (98 per cent) or lower lumbar nerve roots. Based on objective grading by the clinician and subjective assessment by the patient complete success was achieved in 62 per cent of the patients and partial success in 24 per cent. Provided there is full appreciation of the pathological anatomy, strict diagnostic criteria and meticulous surgery, decompression of the nerve root canal is a useful surgical procedure in severely disabled patients suffering from isolated disc resorption
