The Mayo Conservative Hip: experience from a district general hospital.
The Mayo Conservative Hip femoral prosthesis has been designed to optimise proximal femoral loading as well as preserving proximal femoral bone stock. Between October 2003 and May 2006, 42 patients (49 hips) underwent total hip replacement (THR) using the Mayo Conservative Hip femoral component. The mean age at operation was 57.8 years (range 44 to 74) and the mean clinical follow up was 3.1 years (range 2.3 to 4.7 years). The aim of our study was to review the short term results of this unorthodox femoral component. We found that 18% degrees of stems were malaligned >or= 5 degrees and the prevalence of intra-operative femoral fracture was 4%. We feel this prosthesis is difficult to implant and has an unacceptable fracture rate.
