Comparison of four metal fixation implants for femoral intertrochanteric fractures in old patients / 中国组织工程研究

ABSTRACT

BACKGROUND:The selection of metal implant for old patients with femoral intertrochanteric fracture should focus on patient’s age, osteoporotic degree, perioperative status and type of fracture. Individual therapeutic program should be made. OBJECTIVE:To compare the therapeutic effects of four types of metal implant fixation for femoral intertrochanteric fracture in old patients. METHODS:180 old patients with femoral intertrochanteric fractures treated from September 2009 to September 2012 were analyzed. Four kinds of metal implants were used for repair of fracture. There were 45 patients in the dynamic hip screw group, proximal femoral nail anti-rotation group, Gamma nail group and anatomical dynamic hip lock nickelclad group, separately. Operation time, blood loss, hospital time, Harris score after operation, fracture healing time and complications in different groups were compared. RESULTS AND CONCLUSION:Operation time and hospital time were shorter, and blood loss was fewer in the anatomical dynamic hip lock nickelclad group and proximal femoral nail anti-rotation group compared with the dynamic hip screw group and Gamma nail group (P0.05). The incidence of complications was significantly lower in the anatomical dynamic hip lock nickelclad group and proximal femoral nail anti-rotation group compared with the Gamma nail group and dynamic hip screw group (P<0.05). Results suggested that anatomical dynamic hip lock nickelclad and proximal femoral nail anti-rotation are reliable in treatment of intertrochanteric fracture in old patients, show less postoperative complications, and are ideal choices for implant fixation of femoral intertrochanteric fracture in old patients.
