Comparison And Analysis Of Two Methods In Treatment Of Senile Femoral Intertrochanteric Fracture

Most intertrochanteric fracture occur in eldly inviduals. The incidence of fracture of the intertrochanteric fracture is increasing, not unexpectedly.since the general life expectancy of the population has increased significantly during the past few decades.Operative treatment can decrease complication and motality rate and the patients can recover early. DHS has the function of compression and sliding and is relatively an ideal implant for treatment of intertrochanteric fracture at present.ObjectiveTo study the effects of dynamic hip screw(DHS) and non-operative treatment for treatment of senile femoral intertrochanteric fracture.Materials and MethodsTwenty eight cases with femoral intertrochanteric fracture from 1999.10-2002.6in our hospital were divided into two groups randomly according to differenttreatment. Forteen patients were treated surgically with DHS. Forteen patients weretreated conservatively with non-operative treatment.Result1 All the patients were followed up from six months to two and half years. Average age,clinical healing time of fracture were no obvious difference ( P > 0. 05 ) between grouo DHS and group non-operative treatment.Admitted time of grouo DHS were shortened significantly (P<0.01) ,compared with group non-operative treatment.2 The effective rates of group DHS and group non-operative treatment were 92.8% and 78.6% respectively. The effective rates of group DHS was significantly higher than that of group non-operative treatment (P<0.01) .ConclusionThe senile patients with femoral intertrochanteric fracture should be operated . DHS has function of compression and sliding. DHS is relatively an ideal implant for treatment of femoral intertrochanteric fracture at present. The lag screw above the DHS lag screw is effective for controlling the rotation of the fracture. The tail of DHS lag screw should be loose. In the antero-posterior X-ray film,the position of the lag screw should be paralled to the long axis of the neck of the femur .In the lateral X-ray film, the position of the lag screw should be on the medial axis of the femoral neck. The non-operative treatment is nessary in some cases.
