Aims

The aim of this study was to present the long-term surgical outcomes, complications, implant survival, and causes of implant failure in patients treated with the modified Harrington procedure using antegrade large diameter pins.

Aims

The aim of this study was to estimate the cost-effectiveness of negative-pressure wound therapy (NPWT) in comparison with standard wound management after initial surgical wound debridement in adults with severe open fractures of the lower limb.

Aims

We investigated patient characteristics and outcomes of Vancouver type B periprosthetic fractures treated with femoral component revision and/or osteosynthesis.

1. The various surgical procedures in common use for the treatment of the osteoarthritic hip are briefly reviewed and compared with the operation of replacement of both the acetabulum and head of the femur by a metal prosthesis, that is, a complete artificial hip joint. 2. The development, description and technique of insertion of this artificial hip joint are given in detail. 3. The results of the first fifty cases of this operation show a success rate of over 90 per cent. The few failures are analysed in detail. The revision procedure has been the insertion of another artificial hip joint. 4. The essential details necessary for success are stressed and the indications and aims of the operation given

Injury to the dorsomedial cutaneous nerve in the foot may occur after operations for hallux valgus. Pressure neuropathy before operation is also described but remains largely unexplored. We have investigated the incidence of sensory deficit in the great toe before operating for hallux valgus and examined to what extent any deficit was related to the degree of angulation of the joint. Forty-three patients with a total of 61 great toes with hallux valgus presenting for consideration of surgical correction had their sensation tested in pre-designated zones using a five-filament set of Semmes-Weinstein monofilaments. These allowed good inter-observer reliability with an intra-class correlation coefficient of 0.84. Sensory symptoms were noted by only 21% of the patients, a measurable reduction in sensation by one monofilament grade or more was found in an additional 44%. No relationship was found between the degree of sensory loss and the degree of angulation. Patients with symptomatic hallux valgus may have sensory loss in the toe without being aware of it. Normal subjective sensation does not reliably predict normal sensory function. Given the potentially high rates of nerve damage following operations for hallux valgus, we recommend objective sensory testing as part of routine assessment before surgery

There is evidence that high levels of physical activity following arthroplasty of the hip or knee can lead to early revision. However, the term ‘highly active’ is not well defined. . A validated ankle accelerometer was used to quantify activity in 13 patients, who had undergone a total of 20 arthroplasties of the lower limbs and who had active lifestyles. The assessments were taken at a mean of 8.7 years post-operatively (1.8 to 15.8). The mean gait cycles per day was 8273 (5964 to 12 557), which extrapolates to 3.0 million cycles per year (cpy) (2.2 to 4.6). The mean percentage of time spent in high activity mode was 4.3%, or about one hour per day. The mean percentage of cycles in high activity was 40%. . Based on these data, we propose the following definitions of high activity: > 3 million cpy; one hour per day in high activity mode; 40% of cycles in high activity mode. . Extrapolating the sample of activity over the time since operation, the mean cycles per arthroplasty was 25.2 million, with a maximum of 44.1 million. No joint has been revised, or shows evidence of impending failure. Cite this article: Bone Joint J 2016;98-B(1 Suppl A):95–7

Aims

The aim of this study was to compare the osseous reactions elicited by all-suture, polyetheretherketone (PEEK), and two different biodegradable anchors used during rotator cuff repair.

We measured the serum concentration of C-reactive protein (CRP) by a high-sensitive method in patients with lumbar disc herniation. There were 48 patients in the study group and 53 normal controls. The level and type of herniation were evaluated. The clinical data including the neurological findings, the angle of straight leg raising and post-operative recovery as measured by the Japanese Orthopaedic Association (JOA) score, were recorded. The high-sensitive CRP (hs-CRP) was measured by an ultrasensitive latex-enhanced immunoassay. The mean hs-CRP concentration was 0.056 ± 0.076 mg/dl in the patient group and 0.017 ± 0.021 mg/dl in the control group. The difference was statistically significant (p = 0.006). There was no other correlation between the hs-CRP concentration and the level and type of herniation, or the pre-operative clinical data. A positive correlation was found between the concentration of hs-CRP before operation and the JOA score after. Those with a higher concentration of hs-CRP before operation showed a poorer recovery after. The significantly high concentration of serum hs-CRP might indicate a systemic inflammatory response to impingement of the nerve root caused by disc herniation and might be a predictor of recovery after operation

1. A review of 193 African and Indian children suffering from spina bifida has been made. Forty-three were seen on the first day of life and the remainder during subsequent weeks of life. 2. For the baby with mild or moderate paralysis and an open spinal lesion early closure was of value in preventing progressive neural damage. 3. For the baby with severe paralysis and an open myelomeningocele early operation was not of value in preventing further neural damage, and all remained severely paralysed. immediate operation to close the spinal lesion is not justified in babies with severe paralysis: survivors may be treated by later operation to prevent recurrent meningitis

1. Correction of equinus deformity in cerebral palsy either by elongation of the tendo calcaneus or by gastrocnemius recession gives satisfactory results without splintage or bracing after operation. 2. Gastrocnemius recession is the operation of choice in paraplegic spastic cerebral palsy, and wherever possible in tetraplegic cerebral palsy. In hemiplegia the whole of the triceps surae is usually involved, and elongation of the tendo calcaneus is almost always needed. 3. Correction at operation should aim to result in a mild degree of equinus deformity at the end of the growth period in hemiplegic spastic cerebral palsy. Over-enthusiastic gastrocnemius recession can lead to excessive weakness of the calf in some patients

Aims

The aim of this meta-analysis was to compare the outcome of total elbow arthroplasty (TEA) undertaken for rheumatoid arthritis (RA) with TEA performed for post-traumatic conditions with regard to implant failure, functional outcome, and perioperative complications.

Thirty patients with chronic pyogenic or tuberculous arthritis of the hip treated by Girdlestone's excision arthroplasty were reviewed two to seven years after operation. There was marked or complete relief of pain in 29, control of infection in 27, squatting and sitting cross-legged was possible in 27, and 16 were able to stand on the operated limb. Overall results were good in 16, fair in nine, and poor in five. Tuberculous disease was not reactivated and the use of traction for 12 weeks and a weight-relieving caliper for 12 months after operation helped to reduce the shortening to an average of 3.8 centimetres. Excision arthroplasty is considered a sound operation to restore the ability to squat and sit cross-legged

1. Five cases of involvement of vertebrae by growths classified as giant-cell tumours, and two cases of involvement by tumours classified as aneurysmal bone cysts are described. 2. The periods of observation after operation in the benign cases were in three cases six years, in one ten years and in one twenty-one years. 3. In one case malignant transformation developed four and a half years after operation and one patient, in whom a sacral tumour was already malignant at the time of operation, died five months later. 4. Four patients showed significant involvement of vertebral bodies. 5. The problems related to the removal of a vertebral body and the measures taken to stabilise the spine are discussed

1 . Thirty-six patients with complete irrecoverable brachial plexus lesions have been studied. 2. Function has been compared after 1) arthrodesis of the shoulder with amputation through the arm, 2) so-called reconstructive procedures, and 3) no operative treatment. 3. The results of reconstructive operations have been so disappointing that we believe that this type of treatment should be abandoned. 4. Amputation-arthrodesis offers a better functional result than either reconstruction or no operation. Its value depends to a considerable extent on the manual dexterity of the patient. 5. A clerical worker who is not mechanically minded is less likely to use an artificial limb, and in this type of patient operation is perhaps best avoided

We have reviewed 13 operations on 11 patients using curettage and polymethylmethacrylate cement for giant-cell tumour of bone (GCT) to assess the value of radiology in the early detection of recurrence. There were four recurrences, the most specific radiological sign on plain radiography was lysis of 5 mm or more at the cement-bone interface. This preceded clinical signs by a mean of four months and was identified at a mean of 3.75 months after operation. There was not always a complete sclerotic margin around the cement, but when it was present, there was never evidence of recurrence. MRI was helpful in assessing cases with evidence of recurrence. Frequent surveillance with plain radiography should continue for one year after operation irrespective of clinical signs of recurrence. When the appearance of the plain radiographs suggests recurrence, MRI should be performed and followed by image-guided needle biopsy

Aims

Arthroplasty skills need to be acquired safely during training, yet operative experience is increasingly hard to acquire by trainees. Virtual reality (VR) training using headsets and motion-tracked controllers can simulate complex open procedures in a fully immersive operating theatre. The present study aimed to determine if trainees trained using VR perform better than those using conventional preparation for performing total hip arthroplasty (THA).

We performed MRI on 16 patients who had had reconstruction of the anterior cruciate ligament (ACL) with a mid-third bone-patellar-tendon-bone autograft. Our aim was to assess the tendon and the site of its insertion at an average of seven years after the original operation. In four of these patients biopsies were taken from the donor site when they had revision of their original operation. MRI showed reconstitution of the tendon into the patellar defect with no evidence of bone formation. Six patients had a persistent defect in the patellar tendon itself. Histological examination of the biopsies of the donor site showed an indirect pattern of insertion with absence of the normal fibrocartilage zone. These morphological changes may adversely affect the biomechanical properties of the healed donor site and we suggest that another graft taken from this site may not be suitable for use in a further operation for reconstruction of the ACL

The conservative management of chronic calcaneal paratenonitis is time-consuming and often unsatisfactory. A new, safe and simple technique is described. The crural fascia on both sides of the tendon is incised and left open, adhesions around the tendon are trimmed away, the strongly hypertrophied portions of the paratenon are removed and mobilisation is begun immediately after operation. Between 1961 and 1978 201 such operations were performed on 182 patients 62 of whom were top-ranking Finnish athletes. Only five patients were not athletes. The results, including early return to full activity, were excellent in 169, good in 25 and poor in seven cases. After operation one of the patients gained an Olympic gold medal; others have attained international prominence

The February 2013 Foot & Ankle Roundup. 360 . looks at: replacement in osteonecrosis of the talus; ankle instability in athletes; long-term follow-up of lateral ankle ligament reconstruction; an operation for Stage II TPD; whether you should operate on Achilles tendon ruptures; Weil osteotomies and Freiberg’s disease; MRI scanning not sensitive for intra-articular lesions; and single-stage debridement and reconstruction in Charcot feet

1. Of fifty consecutive double hemiarthroplasties of the knee for rheumatoid arthritis using Maclntosh prostheses, forty-six were available for detailed assessment in thirty-six patients after one to six years. 2. Two early deaths were related to the operation but two late deaths were not. Three knees required revision, one of them twice. 3. The late results were 87 per cent good and 13 per cent fair. No patients followed up were the same as previously or worse. Every patient stated that he would have the operation performed again. 4. In our experience this operation in carefully selected patients produces satisfactory results. It is essential that great care is given to the operative technique
