    Abstract:
    OBJECTIVE: To retrospectively study the clinical results of total hip arthroplasty(THA) using Wagner SL revision stem for patients with femoral intertrochanteric fracture. METHODS: From 2006 January to 2009 December, 29 consecutive patients with femoral intertrochanteric fractures were performed THA using Wagner SL revision stem and intertrochanteric reconstruction, including 18 males and 11 females with an average age of 49 years old ranging from 43 to 58. Among them, 8 cases were oboslete femoral intertrochanteric fractures and 21 cases were the intertrochanteric fractures with painful arthritis before injuries. After the operation, the follow-up results were evaluated with clinical and radiographic criteria. The clinical follow-up results were evaluated by Harris score, limb length discrepancy, ROM of hips and the strength of the hip abductor. The X-ray imaging follow-up results were evaluated by periprosthetic osteolysis, prosthesis loosening and radiolucent. RESULTS: All the operations were successfully completed without serious complications associated with THA. Twenty-nine cases were followed up for a mean duration of 8.2 years (ranged, 6 to 10). There was no acceptable thigh pain. The first time walk after operation, 8 patients with oboslete intertrochanteric fracture complained the surgical sides were longer, with the passage of time, the complaint significantly reduced. At 3 months after operation, X-ray films of 21 cases showed intertrochanteric fractures healed well who had painful arthritis before injuries. An average of 6 months after operation (ranged, 3 to 8), X-ray films of 8 cases of oboslete intertrochanteric fracture showed that the bone graft and trochanter with obvious callus connection. There were no obvious prosthesis subsidence on X-ray film at the final follow-up. The recovery of hip movement range was satisfactory, no hip abduction strength was weak. More than 6 years after the operation, according to the Harris scoring evaluation of hip joint, the result was excellent in 18 cases, good in 9 cases, general in 2 cases. CONCLUSIONS: The clinical results of total hip arthroplasty using Wagner SL revision stem for patient with femoral intertrochanteric fracture is a reliable method, intertrochanteric reconstruction not only makes for prosthesis and joint stability, but also increases bone reserve.
