Aims

HIV predisposes patients to opportunistic infections. However, with the establishment of Highly Active Anti-Retroviral Therapy (HAART), patients’ CD4 counts are maintained, as is a near normal life expectancy. This study aimed to establish the impact of HIV on the bacteriology of spondylodiscitis in a region in which tuberculosis (TB) is endemic, and to identify factors that might distinguish between them.

Aims

We studied the impact of direct anterior (DA) versus non-anterior (NA) surgical approaches on prosthetic joint infection (PJI), and examined the impact of new perioperative protocols on PJI rates following all surgical approaches at a single institution.

Smoking is an important risk factor for the development of postoperative pulmonary complications after major surgical procedures. We studied 811 consecutive patients who had undergone hip or knee arthroplasty, recording current smoking and drinking habits, any history of chronic disease and such intraoperative factors as the type of anaesthesia and the type and duration of surgery. We recorded any postoperative complications occurring before discharge from hospital. There were 232 smokers (28.6%) and 579 non-smokers. We found that smoking was the single most important risk factor for the development of postoperative complications, particularly those relating to wound healing, cardiopulmonary complications, and the requirement of postoperative intensive care. A delay in discharge from hospital was usual for those suffering a complication. In those patients requiring prolonged hospitalisation (> 15 days) the proportion of smokers with wound complications was twice that of non-smokers

We compared thromboembolic events, major haemorrhage and death after total hip replacement in patients receiving either aspirin or low-molecular-weight heparin (LMWH). We analysed data from the National Joint Registry for England and Wales linked to an administrative database of hospital admissions in the English National Health Service. A total of 108 584 patients operated on between April 2003 and September 2008 were included and followed up for 90 days. Multivariable risk modelling and propensity score matching were used to estimate odds ratios (OR) adjusted for baseline risk factors. An OR <  1 indicates that rates are lower with LMWH than with aspirin. In all, 21.1% of patients were prescribed aspirin and 78.9% LMWH. Without adjustment, we found no statistically significant differences. The rate of pulmonary embolism was 0.68% in both groups and 90-day mortality was 0.65% with aspirin and 0.61% with LMWH (OR 0.93; 95% CI 0.77 to 1.11). With risk adjustment, the difference in mortality increased (OR 0.84; 95% CI 0.69 to 1.01). With propensity score matching the mortality difference increased even further to 0.65% with aspirin and 0.51% with LMWH (OR 0.77; 95% CI 0.61 to 0.98). These results should be considered when the conflicting recommendations of existing guidelines for thromboprophylaxis after hip replacement are being addressed

This is the first study to use the English Indices of Multiple Deprivation 2007, the Government’s official measure of multiple deprivation, to analyse the effect of socioeconomic status on the incidence of fractures of the hip and their outcome and mortality. Our sample consisted of all patients admitted to hospital with a fracture of the hip (n = 7511) in Nottingham between 1999 and 2009. The incidence was 1.3 times higher (p = 0.038) in the most deprived populations than in the least deprived; the most deprived suffered a fracture, on average, 1.1 years earlier (82.0 years versus 83.1 years, p < 0.001). The mortality rate proved to be significantly higher in the most deprived population (log-rank test, p = 0.033), who also had a higher number of comorbidities (p = 0.001). This study has shown an increase in the incidence of fracture of the hip in the most deprived population, but no association between socioeconomic status and mortality at 30 days. Preventative programmes aimed at reducing the risk of hip fracture should be targeted towards the more deprived if they are to make a substantial impact

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

There have been only a few small studies of patients with an infected shoulder replacement treated with a single-stage exchange procedure. We retrospectively reviewed 35 patients (19 men and 16 women) with a peri-prosthetic infection of the shoulder who were treated in this way. A total of 26 were available for clinical examination; three had died, two were lost to follow-up and four patients had undergone revision surgery. The mean follow-up time was 4.7 years (1.1 to 13.25), with an infection-free survival of 94%. The organisms most commonly isolated intra-operatively were Staphylococcus epidermidis and Propionibacterium acnes; two patients developed a recurrent infection. Three different types of prosthesis were used: a hemiarthroplasty, a hemiarthroplasty with a bipolar head and reverse prosthesis. The mean Constant-Murley score at final follow-up was 43.3 (14 to 90) for patients with a hemiarthroplasty, 56 (40 to 88) for those with a hemiarthroplasty with a bipolar head and 61 (7 to 90) for those with a reverse prosthesis. The mean hospital stay was 10.6 days (5 to 29). Single-stage exchange is a successful and practical treatment for patients with peri-prosthetic infection of the shoulder.

The purpose of this study was to establish whether exploration and neurolysis is an effective method of treating neuropathic pain in patients with a sciatic nerve palsy after total hip replacement (THR). A total of 56 patients who had undergone this surgery at our hospital between September 1999 and September 2010 were retrospectively identified. There were 42 women and 14 men with a mean age at exploration of 61.2 years (28 to 80). The sciatic nerve palsy had been sustained by 46 of the patients during a primary THR, five during a revision THR and five patients during hip resurfacing. The mean pre-operative visual analogue scale (VAS) pain score was 7.59 (2 to 10), the mean post-operative VAS was 3.77 (0 to 10), with a resulting mean improvement of 3.82 (0 to 10). The pre- and post-neurolysis VAS scores were significantly different (p < 0.001). Based on the findings of our study, we recommend this form of surgery over conservative management in patients with neuropathic pain associated with a sciatic nerve palsy after THR.

Aims

There is little literature about total knee arthroplasty (TKA) after distal femoral osteotomy (DFO). Consequently, the purpose of this study was to analyze the outcomes of TKA after DFO, with particular emphasis on: survivorship free from aseptic loosening, revision, or any re-operation; complications; radiological results; and clinical outcome.

Diastematomyelia is a rare congenital abnormality of the spinal cord. This paper summarises more than 30 years’ experience of treating this condition. Data were collected retrospectively on 138 patients with diastematomyelia (34 males, 104 females) who were treated at our hospital from May 1978 to April 2010. A total of 106 patients had double dural tubes (type 1 diastematomyelia), and 32 patients had single dural tubes (type 2 diastematomyelia). Radiographs, CT myelography, and MRI showed characteristic kyphoscoliosis, widening of the interpedicle distance, and bony, cartilaginous, and fibrous septum. The incidences of symptoms including characteristic changes of the dorsal skin, neurological disorders, and congenital spinal or foot deformity were significantly higher in type 1 than in type 2. Surgery is more effective for patients with type 1 diastematomyelia; patients without surgery showed no improvement

1. The results of treatment of fractures of the shaft of the femur in fifty patients aged sixty-five years and over seen over a twelve-year period are presented. 2. Half of the patients were treated by internal fixation and half by conservative methods. The mortality in the former group was three times that of the latter. 3. The length of hospital stay was only slightiy less after internal fixation because many patients in both groups had to remain in hospital because of social problems. 4. The indications for internal fixation of fractures of the shaft of the femur in elderly patients are discussed

Using a regional arthroplasty register, we assessed the outcome, at five years, of 1198 primary Charnley total hip replacements (THRs) undertaken across a single health region in England in 1990. An independent clinical and radiological assessment was completed for 497 operations, carried out in 18 different hospitals, under the care of 56 consultants and by differing grades of surgeon. The overall number of failures in this group was 44 (8.9%). We found that the risk of failure in patients operated on by a consultant whose firm carried out 60 or more THRs in 1990 was 25% of that of patients under the care of a consultant whose firm undertook less than 30, adjusting for a number of patient, surgeon and hospital characteristics (16% v 4%; p < 0.001 for linear trend). Our study shows that the early outcome of hip replacement surgery varies with the number of replacements undertaken by the consultant firm. A national arthroplasty register would be a convenient source for such data

Aims

Increasingly, patients with bilateral hip arthritis wish to undergo staged total hip arthroplasty (THA). With the rise in demand for arthroplasty, perioperative risk assessment and counselling is crucial for shared decision making. However, it is unknown if complications that occur after a unilateral hip arthroplasty predict complications following surgery of the contralateral hip.

Aims

The aim of this study was to report the results of custom-made endoprostheses with extracortical plates plus or minus a short, intramedullary stem aimed at preserving the physis after resection of bone sarcomas in children.

Aims

The aim of this study was to evaluate the differences in revision and complication rates, functional outcomes, and radiological outcomes between cemented and press-fit humeral stems in primary anatomical total shoulder arthroplasty (TSA).

We have investigated in a prospective, randomised placebo-controlled study the effect of high-dose aprotinin on blood loss in patients admitted for major surgery (revision arthroplasty of the hip or knee, or for resection of a soft-tissue sarcoma). The mean intraoperative blood loss was reduced from 1957 ml in the control group to 736 ml in the aprotinin group (p = 0.002). The mean requirement for intraoperative homologous blood transfusion in the aprotinin group was 1.4 units (95% CI 0.2 to 2.7) and 3.1 units (95% CI 1.7 to 4.6) in the control group (p = 0.033). The mean length of hospital stay was reduced from 27.8 days in the control group to 17.6 days in the aprotinin group which was not statistically significant. The intraoperative use of aprotinin in major orthopaedic operations significantly reduced blood loss and the required amount of packed cells. It may result in a decrease in the length of hospital stay and costs

Aims

The aim of this study was to investigate the differences in 30-day outcomes between patients undergoing revision for an infected total hip arthroplasty (THA) compared with an aseptic revision THA.
