The purpose of this study was to determine to what extent hip joint separation occurs during normal gait on a treadmill and an abduction/adduction leg-lift maneuver in patients who have undergone total hip arthroplasty (THA). Eight patients who had a total of 10 successful unconstrained THAs (Harris Hip Scores >90) performed successive gait motions on an electronically powered treadmill and an abduction/adduction leg lift while under fluoroscopy. The fluoroscopic video images were analyzed… CONTINUE READING
