Introduction

Preoperative psychological distress has been reported to predict poor outcome and patient dissatisfaction after total hip replacement (THR). We investigated this relationship in a prospective multi-centre study between January 1999 and January 2002.

We aimed to assess whether using long stem femoral components, with cemented distal fixation and proximal impaction grafting allows early patient mobilisation, reconstitution of the proximal femur and long term stability of fixation in patients with aseptic loosening and proximal femoral analysis.

Over the past ten years 239 patients have been treated with an Elite Plus cemented long stem femoral implant, 33% with concomitant proximal impaction bone grafting. Many of the patients had co-morbidities. The average age at revision was 72 years (range 48 to 91). There was a slight female predominance. Fourteen percent of hips had been previously revised. Forty-eight patients were deceased and 22 were not available for follow-up; this left a cohort of 169 patients who were available for radiological and questionnaire review at an average of 4.5 years.

According to the Paprosky grading for pre-operative bone loss 40% had moderate to severe bone loss (grade IIIb or IV). The Barrack grading was used to assess the cement mantle post-operatively with 65% showing good cementation. The Harris and O'Neill grades were used at final review to assess probability of loosening with only 8% being probably or definitely loose. The average Oxford Hip Score was 29. Mesh ± cables were required in a third of cases to allow adequate containment and pressurisation. It was generally felt that the long stem needed to be at least one third longer than the initial component. The re-revision rate was 1.2 with a 10 year survivorship analysis of 94%. The complication rate of almost 6% included periprosthetic fractures, dislocations, infection and mesh breakage.

A long stem cemented femoral implant can be useful in bypassing proximal femoral deficiency in the appropriate patient.
