Introduction

Although hip arthroplasty has been very successful in relieving pain and optimising function, problems have arisen with wear and osteolysis. Highly cross linked polyethylene has been developed to address this problem. The aim of this study was to compare the in vivo wear of standard versus highly cross linked polyethylene (HXLP) in primary total hip arthroplasty at 5-year follow up.

Methods

Approval was obtained through the Regional Ethics Committee before commencement of the study. 122 patients were enrolled in a prospective, double blinded, randomised trial and followed annually to assess their progress. Annual radiographs were analysed using previously validated edge detection software to assess for 2 dimensional, 3 dimensional and volumetric wear. To reduce the disproportionate effects of bedding in and creep, the initial x-ray used was that taken at 6 months following surgery.

The distal femur fracture is a difficult injury that affects young men andelderly women. The tissue stripping that occurs with the traditional approach has been a factor in the development of complications like infection and nonunion. This study addresses the issue of minimally invasive approach. Does the LISS system really improve the results of such fracture?

Fifty-two patients were included in the trial from six academic trauma centres. Twenty-eight fractures had been randomised to be fixed with the LISS device, while twenty-four had the DCS implant. Type C3 fractures were excluded as they were not amenable for fixation with DCS system. All procedures were performed via minimally invasive technique. The LISS system had the targeter that helped with plate insertion and distal diaphyseal screws placement. Radiography was utilised in the case of the DCS distal screws insertion.

All fractures went onto union, except two participants in LISS group who had to be revised due to loss of reduction, in the early post-operative peroid. There were three nonunions in the same group. These required a re-operation. Further more, a LISS participant who had re-injured his distal femur (unrelated to LISS plate), was fixed with different implant. There was a single nonunion with the DCS group that needed revision surgery. There was one participant from each group who had drifted into varus. Neither required a re-operation. This translated into a 21% re-operation rate in the LISS system compared to 4% with the DCS device.

Our data supports the use of the DCS system in the fixation of distal femur fractures (except Type C3} via a minimally invasive approach. The LISS implant seems to be technique dependent. In our centre, the LISS plate had been discontinued in favour of the DCP and LCP systems.

Purpose

The objective of this meta-analysis was to compare the effects of early and delayed surgery on the risk of mortality, common post-operative complications, and length of hospital stay among elderly hip fracture patients.

Methods

We searched MEDLINE and EMBASE for relevant prospective studies evaluating surgical delay in patients undergoing surgery for hip fractures published in all languages between 1966 and 2008. Two reviewers independently assessed methodological quality and extracted relevant data.
