Clinical Study for Measurement of Stem Antetorsion during Total Hip Arthroplasty. Ct Free Navigation Vs G-guide
Implant positioning is one of the critical factors influencing the postoperative outcome in total hip arthroplasty (THA) [1.2]. In our previous study, we evaluated the Combined anteversion (CA) value in patients who underwent THA using an image-free navigation for the cup with manual adjustment of the stem. Consequently, the AT value showed wide variability [3].Since March 2013, we have measure...
متن کاملUse of the G-guide for Measuring Stem Antetorsion During Total Hip Arthroplasty.
Implant positioning is one of the critical factors influencing postoperative outcomes in total hip arthroplasty (THA). Several studies have reported that the postoperative antetorsion (AT) measurement for the femoral stem inserted without navigation showed wide variability. The current authors developed a simple instrument, the Gravity-guide (G-guide), for intraoperative assessment of stem AT a...
متن کاملAccuracy of Combined Anteversion in the Combined Anteversion Technique with Image-free Navigated Total Hip Arthroplasty
In recent literatures dealing with optimization of prosthetic alignment in total hip arthroplasty (THA), the concept of combined anteversion (CA), which is the sum of acetabular anteversion (AV) and femoral antetorsion (AT), has been addressed. Widmer attempted to determine the optimal CA using a computer simulation study . He proposed the “new safe zone” for the CA value to achieve essential r...
متن کاملCombined anteversion of the total hip arthroplasty implanted with image-free cup navigation and without stem navigation
In total hip arthroplasty (THA), combined anteversion (CA), the sum of cup anteversion (AV) and stem antetorsion (AT) are used as parameters to assess the appropriateness of overall prosthetic alignment. In this study, we evaluated the CA value based on the post-operative computed tomography (CT) measurements in our patient population who underwent THA using the OrthoPilot™ image-free navigatio...
متن کاملAccuracy of Component Orientation and Leg Length Adjustment in Total Hip Arthroplasty Using Image-free Navigation
Purpose The purpose of this study was to examine the accuracy of implant orientation and leg length in total hip arthroplasty (THA) with an image-free navigation system based on a comparison of the intraoperative navigation and postoperative CT evaluations. Material and Methods A consecutive series of 111 patients (118 hips) who underwent THA using the current version of the image-free naviga...
