Customized 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 کاملFemoral head blood flow during hip resurfacing.
Preserving femoral head vascularity during hip resurfacing may avoid femoral neck fractures and late femoral loosening. The posterior approach and notching of the femoral neck influence femoral head perfusion. However, it is not known if standard preparation of the femoral head during hip resurfacing can disrupt blood flow. Ten patients (10 hips) with advanced osteoarthritis having metal-on-met...
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...
متن کاملA simple and reliable technique for placing the femoral neck guide pin in hip resurfacing arthroplasty.
Early failure of hip resurfacing has been attributed to component malposition and other factors. Accurate placement of the femoral guide pin is challenging with commercial guides, and computer navigation adds considerable cost to the procedure. Precise pin placement can be achieved by drilling a 2.8-mm pin across the hip joint in a retrograde fashion similar to placing a dynamic hip screw pin. ...
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...
