简要总结
This study showed that ASS technique can restrain the displacement of the proximal bone fragment to the intramedullary type and excessive sliding of lag screw which leads to postoperative complications such as re-dislodgement of bone fragment and cut-out, in the treatment of femoral trochanteric fractures without appropriate posterior bony support.
