RESUMEN
Objective To observe the clinical effect and follow-up outcome of the osteoporotic femoral intertrochanteric fractures after treatment with DHS in the elderly. Methods Sixty-six cases with OFIF were treated with open reduction and percutaneons insertion of DHS during February 2003 to April 2007. All patients took the microclosed reduction and anti-osteoporotic medicines during the treatment and they were followed up for outcome and complications. Results All patients were followed up for a mean duration of 13.5 (6～18) months, the average fracture healing time was 3～4 months. Harris scores excellent was 34 cases and good was 22 cases. The excellent and good rate of osteoporosis was 100%. No non-union mechanical fixation failure, bone cut out or severe nerve and vessel injury was noticed. Percutaneous insertion of DHS is effective in treatment of osteoporotic intertrochanteric fractures in the elderly. Conclusion The surgical principles include use of simple, effective and safe method, less functional influence and good mechanic fixation, which can reduce the complications and promote early recovery.
