Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study mainly measures the orientation of acetabulum cup post total hip arthroplasty. Using "Liaw's Version", a new and accurate standardization method, investigators are trying to analyze acetabulum cup anterversion change postoperatively.
As previously known, the anteversion of acetabulum cup determines the range of motion, stability, and the function after total hip arthroplasty. Cup malalignment increase impingement, dislocation, cup migration, and polyethylene wear. Finding a pattern may help the early diagnosis of acetabular loosening.
