Abstract

• There are many problems in the treatment of the intertrochanteric fracture due to osteoporosis and unstable patten of fracture in elderly patients, which are also determined by quality of the bone, geometry and reduction of the fragments, and type and placements of the implant. The Gamma nail has recently become available for the treatment of intertrochanteric femur fracture.
  The authors analysed the intertrochanteric fracture of the 33 patients who were operatively treated with Gamma nail and followed up more than 3 years from May, 1991 to June, 1994 to evaluate the results and prognostic factors.
  The results obtained were as follws;
  1. Type III in TronBo classification was the most common(58%).
  2. Among the 33 cases, the patients with osteoporosis below grade III of Singh index were 26 cases(78.8%). In osteoporotic group(Singh index I-III), unstable type fracture was more common(85%).
  3. The complication was developed in 8 cases(24.2%), of which cutting out from the femoral head was found in 4 cases.
  4. The complication rate statistically had significant correlation with severity of osteoporosis.
• Key words: Femur, Intertrochanteric fracture, Gamma nail
