Abstract

IntroductionSuitable treatment of early failure of total hip replacement is critical in younger patients, as bone stock is lost and the functional outcome is impaired.Case presentationWe report the case of a 56-year-old Caucasian woman with early failure of hip resurfacing arthroplasty. While revision is usually performed with a conventional hip implant, this case report describes for the first time a revision procedure with a bone-conserving short-stem hip implant.ConclusionsOur approach allows further conservation of femoral bone stock and provides a long-term solution to the patient, which maintains the possibility of using a conventional hip implant should a second revision become necessary.

Highlights

Suitable treatment of early failure of total hip replacement is critical in younger patients, as bone stock is lost and the functional outcome is impaired
Only a few studies have reported on the revision of failed hip resurfacing arthroplasty (HRA) implants and all revisions have exclusively been performed by the use of a conventional stem [4,5]
We describe a woman with early failure of HRA

Summary

Introduction

The good clinical results in hip arthroplasty have led to an increasing number of joint replacements in younger patients. Revision was performed with a bone-conserving short-stem hip implant, which minimizes the bone loss on the femoral side in order to facilitate potential revision surgery. As conservative treatment had failed, she requested hip replacement arthroplasty Due to her comparatively younger age and activity level, HRA (CormetTM, Corin Group, Cirencester, UK) was performed. Her post-operative course was unremarkable and the final radiological assessment showed an implant position with a cup inclination of 50° and a stem-shaft angle of 132°. Revealed a failure of the acetabular component, which was already dislocated, and showed a narrowing of the femoral neck (Figure 1) For those reasons, our patient underwent revision surgery. Intra-operatively, a massive metallosis of the peri-prosthetic tissue was found and the femoral and acetabular components were already
