Varus positioning of cemented ‘composite beam’ stems is associated with increased risks of aseptic loosening and stem fracture. We investigated whether the incidence of varus malalignment of the Exeter polished, double taper design in a multicentre prospective study adversely affected outcome after total hip replacement (THR). A multicentre prospective study of 1189 THR was undertaken to investigate whether there is an association between surgical outcome and femoral stem malalignment. The primary outcome measure was the change in the Oxford hip score (OHS) at five years. Secondary outcomes included the rate of dislocation and revision, stem subsidence, quality of cementing. 938 (79.89%) were followed-up at five years.Introduction
Materials & Methods
The purpose of this study was to investigate the difference in the level of pre- and 6 months post-operative objective and subjective measures of disability between patients with full-thickness rotator cuff tears and those with impingement syndrome/low grade partial thickness rotator cuff tears. Impact of age, gender, and job demands was taken into consideration. Standardised pre- and post-operative data were collected on consecutive patients who had undergone surgery related to rotator cuff pathology. A disease-specific disability measure, the Western Ontario Rotator Cuff (WORC) Index which explores five domains of physical symptoms – life style, work, sports, and emotions – was the primary outcome. Paired and independent non-parametric statistics and multivariable regression analysis were performed.Purpose
