Accuracy of Component Placement in Robotic-Assisted Total Hip Arthroplasty.

Robotic-assisted total hip arthroplasty (THA) is a recent platform introduced to decrease the risk of malpositioned components. The goals of this study were to determine whether intraoperative data on robotic-assisted THA acetabular component position accurately predict postoperative radiographic acetabular component position and to determine whether intraoperative data on robotic-assisted THA ...

Imageless computer navigation for placement of the femoral component in resurfacing arthroplasty of the hip.

We have investigated the accuracy of placement of the femoral component using imageless navigation in 100 consecutive Birmingham Hip Resurfacings. Pre-operative templating determined the native neck-shaft angle and planned stem-shaft angle of the implant. The latter were verified post-operatively using digital anteroposterior unilateral radiographs of the hip. The mean neck-shaft angle determin...

Hip resurfacing arthroplasty

BACKGROUND AND PURPOSE Hip resurfacing arthroplasty is claimed to allow higher activity levels and to give better quality of life than total hip arthroplasty. In this literature review, we assessed the therapeutic value of hip resurfacing arthroplasty as measured by functional outcome. METHODS An extensive literature search was performed using the PubMed, Embase, and Cochrane databases. RES...

Hip resurfacing arthroplasty

Historical context The concept of resurfacing the hip can be traced back to the early 1900s with the various techniques of interposition arthroplasty.1 Smith-Petersen produced a cast cobalt-molybdenum alloy (vitallium) interposition cup in 1940 as a culmination of many years work with different materials.2 Charnley experimented with a polytetrafluoroethylene (PTFE) hip resurfacing as a clear co...
