To investigate the clinical effect of lengthened biological femur shank artificial hip joint replacement in the treatment of intertrochanteric fracture in elderly patients.

Forty-one elderly patients with intertrochanteric fracture treated with lengthened biological femur shank artificial hip joint replacement through posterolateral approach of hip joint were analyzed retrospectively, who were come from the department of orthopedics, the Inner Mongolia autonomous region Chifeng hospital and the second affiliated hospital of Inner Mongolia medical university from February 2010 to August 2015. The hip function was evaluated according to the Harris scoring system after the surgery.

The operation time of the 41 cases in this group was 41-95 min, the average time was 62 min. The intraoperative blood loss was about 180-450 mL, with an average of 300 mL. The postoperative ambulation time of the 41 cases in this group was 3-5 d, the average time was 4 d, the postoperative bed stay time was short. The hospital stay was 12-18 d, with an average of 15 d. There were no complications such as deep vein thrombosis, pulmonary embolism, fat embolism, dislocation of joint, death and so on. Postoperative review, the X-ray showed that the fracture reduction was satisfactory, and the lower extremities were of equal length, the prosthesis position and intertrochanteric fracture were all well restored. After 1-5 years of follow-up, there were no infection, prosthesis loosening, subsidence and rupture, hip varus and valgus deformity, etc. The hip function was evaluated according to the Harris scoring system after the surgery, and the excellent and good rate was 88.7%.

The lengthened biological femur shank artificial hip joint replacement in the treatment of intertrochanteric fracture in elderly patients with short postoperative bed stay time, less complications, rapid recovery of hip function, which can effectively improve the quality of life of postoperative patients.
