Bone morphology of the proximal femoral canal: ethnicity related differences and the influence on cementless tapered wedge stem designs.

Background: Differences in proximal femoral morphology between ethnicities may have implications on the design of cementless tapered wedge stems. This study analyses the differences in Asian and Caucasian bone morphology as well as the related fit of various cementless tapered wedge stem designs.

Methods: A computed tomography database and modelling software was used to retrospectively analyse a total of 1345 femora.

The simplest method to classify CAM lesions.

CAM lesions are now seen as a significant pathology that could cause osteoarthritis of the hip joint. Currently there is no gold standard for classifying these lesions. We aim to show a simple method for classifying these lesions based on shape and position.

Results of the learning curve for interventional hip arthroscopy: a prospective study.

This prospective study aims to explore hip arthroscopy, outcome and the effect of the learning curve. Using the non-arthritic hip score preoperatively and postoperatively in 120 patients with an average 23-month follow-up, a median improvement of 16 points was seen at 6 months (p < 0.0001, Wilcoxon's signed ranks) remaining at 2 years (15, p < 0.

Magnetic resonance arthrography for labral tears and chondral wear in femoroacetabular impingement.

Magnetic resonance arthrography (MRA) is a useful pre-operative investigation for patients with clinical signs and symptoms of femoroacetabular impingement. Our aim was to assess the diagnostic accuracy of MRA in detecting labral tears and chondral wear in this context. Sixty nine hips were included in the study after exclusions.

Incidence and aetiology of talipes equino-varus with recent population changes.

This study looks at the changing incidence and aetiology of congenital talipes equinovarus due to the recent population changes within the area. Between 1st June 1992 and the 31st May 2006, 83 consecutive children (121 feet) born with fixed talipes equinovarus (TEV) were assessed and treated (an incidence of 1.6 per 1000 live births) in an observational longitudinal cohort study assessing associated factors.
