Abstract：BACKGROUND:In dynamic hip screw fixation for treating aged osteoporotic intertrochanteric fracture, avoiding the loss of bone mass, or by other means that can increase the fixed screw pulout strength, wil improve the therapeutic effect of dynamic hip screw fixation. OBJECTIVE: To compare the effects of three kinds of repair methods on aged osteoporotic intertrochanteric fracture. METHODS:Data of aged osteoporosis intertrochanteric fracture patients, who received conventional dynamic hip screw fixation, bone cement augmentation with dynamic hip screw fixation and bone grafting with dynamic hip screw fixation, were retrospectively analyzed. They were divided into control group, bone cement group and bone grafting group. RESULTS AND CONCLUSION:After two years of folow-up, the excelent and good rates of Harris hip function were 95%, 80% and 70% in the bone grafting, bone cement and control groups, respectively. The healing time of fractures was significantly shortened in the bone grafting group (P < 0.05). The failure of screw fixation was similar between the bone grafting and bone cement groups. Screw withdrawing appeared in the control group. Results suggest that compared with conventional dynamic hip screw fixation and bone cement augmentation with dynamic hip screw fixation, the therapeutic effect and safety of bone grafting in nail path with dynamic hip screw fixation were better.
