BACKGROUND:: Femoral intertrochanteric fracture is common fracture in the elderly patients, it was treated with closed and reduction proximal femoral nail/proximal femoral nail anti-rotation internal fixation now, but the treatment effect of the method is not satisfied. OBJECTIVE:: To explore the effect of double-action femoral head replacement for the treatment of unstable femoral intertrochanteric fractures in elderly patients. METHODS:: Thirty-nine patients with unstable femoral intertrochanteric fractures were cured by double-action femoral head replacement, all the patients were followed-up for more than 6 months. Harris score was used to evaluate the hip joint function, and the complications after replacement were observed. RESULTS AND CONCLUSION:: Harris Scores after followed-up for 6 months showed that 17 cases were rated as excellent, 14 cases as good, 8 cases as fair. Three cases of cardiac insufficiency, one case of lung infection, two cases of dislocation (communication barriers, and could not cope with the rehabilitation training after replacement), two cases of deep vein thrombosis and five cases of urinary tract infection. All the patients were cured after symptomatic treatment. There were no serious complications, such as cardiac failure, stress ulcer, pulmonary embolism, periprosthetic infection or death. The treatment of unstable femoral intertrochanteric fractures with double-action femoral head replacement in elderly patients has the advantages of early ambulation weight and fewer complications after replacement.Zhang JD, Xiang LB, Zu QM, Liu GT, Bi Y.
