Are component positioning and prosthesis size associated with hip resurfacing failure?
BACKGROUND Recent studies suggest that there is a learning curve for metal-on-metal hip resurfacing. The purpose of this study was to assess whether implant positioning changed with surgeon experience and whether positioning and component sizing were associated with implant longevity. METHODS We evaluated the first 361 consecutive hip resurfacings performed by a single surgeon, which had a me...
متن کاملCustomized Guide for Femoral Component Positioning in Hip Resurfacing Arthroplasty
OBJECTIVE To prove the accuracy of a customized guide developed according to our method. METHODS This customized guide was developed from a three-dimensional model of proximal femur reconstructed using computed tomography data. Based on the new technique, the position of the guide pin insertion was selected and adjusted using the reference of the anatomical femoral neck axis. The customized g...
متن کاملReply to Letter to Editor: Femoral Component Positioning in Hip Resurfacing with and Without Navigation
We acknowledge Dr. Andrea Emilio Salvi for his general comments and opinions on hip resurfacing surgical technique and factors that may affect clinical outcome. Even if no specific question or comment is directly related to our study [2], we will try to provide a scientific input on the points raised. The first ‘‘procedural trap’’ reported by Dr. Salvi is in relation to the femoral component st...
متن کاملLetter to the Editor: Femoral Component Positioning in Hip Resurfacing with and Without Navigation
UNLABELLED Early failures after hip resurfacing often are the result of technical errors in placing the femoral component. We asked whether image-free computer navigation decreased the number of outliers compared with the conventional nonnavigated technique. We retrospectively compared 51 consecutive hip resurfacings performed using image-free computer navigation with 88 consecutive hip resurfa...
متن کاملFemoral Component Positioning in Resurfacing Arthroplasty
Previous studies have suggested that femoral component positioning in resurfacing arthroplasty may affect strains in the femoral neck that could lead to decreased implant longevity, A strain gaged, Sawbones model was used to determine the femoral neck strains for a variety of resurfacing head translations and angulations. We found that head positions affected strain distributions, most position...
