Abstract: | AIM: The object of this study was to develop a new method to predict the location of the centre of rotation of the hip joint reasonably accurately. METHOD: We collected the coordinates of palpable bony landmarks in 50 patients, 25 males and 25 females, using CT scans to predict the physiological location of the centre of the hip joint centre. RESULTS: The centre of the hip was located, on average, at 12% (+/- 2.9) of the inter-ASIS (anterior superior iliac spine) distance medial, 33% (+/- 3.9) distal and 19% (+/- 2.7) posterior to the anterior superior iliac spine (ASIS). CONCLUSION: Knowledge of the physiological centre of rotation of the hip may be useful in navigation of the cup in total hip arthroplasty. |
