Aims

Fracture clinics are often characterised by the referral of large numbers of unselected patients with minor injuries not requiring investigation or intervention, long waiting times and recurrent unnecessary reviews. Our experience had been of an unsustainable system and we implemented a ‘Trauma Triage Clinic’ (TTC) in order to rationalise and regulate access to our fracture service. The British Orthopaedic Association’s guidelines have required a prospective evaluation of this change of practice, and we report our experience and results.

Aims

Compared with primary total hip arthroplasty (THA), revision surgery can be challenging. The cement-in-cement femoral revision technique involves removing a femoral component from a well-fixed femoral cement mantle and cementing a new stem into the original mantle. This technique is widely used and when carried out for the correct indications, is fast, relatively inexpensive and carries a reduced short-term risk for the patient compared with the alternative of removing well-fixed cement. We report the outcomes of this procedure when two commonly used femoral stems are used.

Aims

The aim of this prospective randomised controlled trial was to compare non-operative and operative management for acute isolated displaced fractures of the olecranon in patients aged ≥ 75 years.

The posterior malleolus component of a fracture of the ankle is important, yet often overlooked. Pre-operative CT scans to identify and classify the pattern of the fracture are not used enough. Posterior malleolus fractures are not difficult to fix. After reduction and fixation of the posterior malleolus, the articular surface of the tibia is restored; the fibula is out to length; the syndesmosis is more stable and the patient can rehabilitate faster. There is therefore considerable merit in fixing most posterior malleolus fractures. An early post-operative CT scan to ensure that accurate reduction has been achieved should also be considered.

Aims

The aim of this study was to investigate the outcomes of Vancouver type B2 and B3 fractures by performing a systematic review of the methods of surgical treatment which have been reported.

Objectives

A variety of operative techniques have been described as under the term ‘Bristow-Latarjet’ procedure. This review aims to define the original procedure, and compare the variation in techniques described in the literature, assessing any effect on clinical outcomes.

Objectives

The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery.

Aims

This pilot study aimed to evaluate prospectively the use of inlet radiographs of the hip as an alternative method of the assessment of reduction after the surgical treatment of developmental dysplasia of the hip (DDH).

We reviewed 52 children, born between 1974 and 1985 with spina bifida affecting L3 and L4, who had dislocated hips. Their motor function was stable and they were able to walk at the time of dislocation. They were interviewed and examined physically and radiologically. Physical function was measured by the Rand Health Insurance Study questionnaire (HIS), the Childhood Health Assessment questionnaire (CHAQ), and by determining the functional level of ambulation according to Hoffer et al (1973). In a subgroup of 12 patients with L4 level of involvement from both treatment groups we measured the metabolic energy consumption while walking. Thirty patients (49 hips) had been treated by operative relocation and 22 conservatively. Ten of the hips treated by operation subluxated or redislocated. The function in the two groups (conservative v operated) was similar (HIS score 7.8 v 8.0, p = 0.45; CHAQ 14 v 13, p = 0.2; level of mobility 0.61 v 0.63, p = 0.5). Patients in whom operation had failed had worse function than did those with successful surgery (HIS score 8.8 v 6.1, p = 0.025) and those with successful surgery had better function than patients treated conservatively (HIS score 8.8 v 8.0, p = 0.15). Function in patients with failed operations, however, was worse than in those who did not have surgical treatment (HIS score 6.6 v 7.8, p = 0.07). In the 12 so examined the operated group had a 30% more energy-efficient gait (0.271 v 0.361 ml O. 2. kg/m, p = 0.05). Patients with failed operations had worse function than those who were not operated on. The benefit of surgical relocation of the dislocated hips was marginal

Aims

The primary aim of this independent prospective randomised trial was to compare serum metal ion levels for ceramic-on-metal (CoM) and metal-on-metal (MoM) bearing surfaces in total hip arthroplasty (THA). Our one-year results demonstrated elevation in metal ion levels above baseline with no significant difference between the CoM and MoM groups. This paper reviews the five-year data.

1. This is a small series and patients have been treated in a variety of ways. Some impressions emerge, however, concerning the importance of initial trauma, the importance of the factor of heredity and the results of treatment. 2. More than 40 per cent of the patients in the series had an injury to the knee before symptoms began, which tends to support the traumatic theory. Twenty of the twenty-three patients who gave a past history of trauma had a lesion on the medial condyle, next to the intercondylar notch, and one patient of the three who had lesions on the lateral femoral condyle suffered from recurrent dislocation of the patella. 3. Although numerous examples have been reported in the literature of osteochondritis dissecans occurring in several members of a family, the family history of only one patient in this series suggested a familial tendency, and this was doubtful. It seems that patients showing a familial tendency are not commonly seen compared with the number of patients presenting with osteochondritis dissecans. 4. It is often stated that osteoarthritic changes will follow if part of the articular surface is lost, as in osteochondritis dissecans, and this belief has led to the school of thought which advocates restoration of the articular surface by reposition of the fragment. While there is no doubt that this method should be used if a large proportion of the weight-bearing surface of a femoral condyle is affected, the argument has less force if a small area is affected. It is interesting to find that of the five patients treated by replacement of a separated fragment four developed osteoarthritis, whereas in the first series only six patients out of the twenty-two developed such changes. Although these former had what appeared to be an accurate reposition of the fragment it is possible that a "step up" on the joint surface was produced, which gave rise to a more rapid deterioration of the articular cartilage. Accurate conclusions cannot be drawn from five patients, but it may be that attempts to reconstruct the articular surface of a femoral condyle can, over a long period of time, give worse results than simple removal of the lesion. 5. The group of patients treated conservatively gave encouraging results, and improved radiographic appearances were seen in most cases. There was also a notable absence of osteoarthritic changes and these results support the view that conservative treatment is indicated in adolescents and children

Aims

One goal of total hip arthroplasty is to restore normal hip anatomy. The aim of this study was to compare displacement of the centre of rotation (COR) using a standard reaming technique with a technique in which the acetabulum was reamed immediately peripherally and referenced off the rim.

Aims

Instability of the hip is the most common mode of failure after reconstruction with a proximal femoral arthroplasty (PFA) using an endoprosthesis after excision of a tumour. Small studies report improved stability with capsular repair of the hip and other techniques, but these have not been investigated in a large series of patients. The aim of this study was to evaluate variables associated with the patient and the operation that affect post-operative stability. We hypothesised an association between capsular repair and stability.

Aims

The aim of this study was to assess the reproducibility and validity of cross table radiographs for measuring the anteversion of the acetabular component after total hip arthroplasty (THA) and to compare it with measurements using CT scans.

Non-traumatic osteonecrosis of the femoral head is a potentially devastating condition, the prevalence of which is increasing. Many joint-preserving forms of treatment, both medical and surgical, have been developed in an attempt to slow or reverse its progression, as it usually affects young patients.

However, it is important to evaluate the best evidence that is available for the many forms of treatment considering the variation in the demographics of the patients, the methodology and the outcomes in the studies that have been published, so that it can be used effectively.

The purpose of this review, therefore, was to provide an up-to-date, evidence-based guide to the management, both non-operative and operative, of non-traumatic osteonecrosis of the femoral head.

Objectives

Unicompartmental knee arthroplasty (UKA) is a demanding procedure, with tibial component subsidence or pain from high tibial strain being potential causes of revision. The optimal position in terms of load transfer has not been documented for lateral UKA. Our aim was to determine the effect of tibial component position on proximal tibial strain.

Aims

Our aim was to investigate the prevalence of Propionibacterium (P.) acnes in the subcutaneous fat and capsule of patients undergoing shoulder surgery for frozen shoulder or instability.

Aims

The purpose of this study was to determine the sensitivity, specificity and predictive values of previously reported thresholds of proximal translation and sagittal rotation of cementless acetabular components used for revision total hip arthroplasty (THA) at various times during early follow-up.
