ABSTRACT
BACKGROUND: Many studies have suggested that artificial joint replacement has a greater advantage in the treatment of cases of elderly osteoporosis, comminuted fractures and unable to internal fixation or failure of internal fixation. OBJECTIVE:To analyze the curative effect of cemented artificial femoral head arthroplasty for treatment of elderly unstable intertrochanteric fracture. METHODS: Totaly 18 patients with unstable intertrochanteric fracture, aged>75 years, were enroled and underwent cemented artificial femoral head arthroplasty. At 3 months after replacement, the curative effect was evaluated according to the Harris hip joint function score method. The early complications after replacement and long-term complications of prosthesis were observed by folow-up. RESULTS AND CONCLUSION:Al these 18 patients were folowed up for 13 to 34 months, and had no infections, pressure sores, femoral shaft fractures and other complications. X-ray films showed that the frauture healed wel, without prosthesis infection, dislocation, loosening, sinking and breaking. After 3 months of replacement, al patients returned to pre-injury level of walking function. The curative effect was excelent for eight cases, good for seven cases, fair for two cases, poor for one case. These results demonstrate that cemented artificial femoral head arthroplasty for treatment of elderly unstable intertrochanteric fracture has good biocompatibility and stability, and can restore the limb function of patients.
