To assess the feasibility of using intraoperative ultrasound to evaluate the femoral head formation; to evaluate the improvement of the forming effect using the intraoperative ultrasound combined with c-arm.
Ultrasound can provide a multi-directional scan of the femoral head and neck junction, and the range of evaluation is larger than that of the intraoperative c-arm. The study was to assess the feasibility of using intraoperative ultrasound to evaluate the femoral head formation; to evaluate the forming of the femoral head and the improvement of the forming effect using the intraoperative ultrasound combined with c-arm.
