Abstract:
This study consisted of 66 peritrochanteric fractures which were treated by the modified Gamma nail (Asian Pacific nail) from August 1993 to October 1995. Sixty-one intertrochanteric fractures and five subtrochanteric fractures were treated in our institution. Average length of follow-up was 15.0 months. Four patients died during follow-up. The results were as follows; Lag screws were ideally introduced in 55 (83%) cases. The mean length in lag screw sliding was 4.3 mm in stable trochanteric fractures and 5.7 mm in unstable ones. Fifty-one out of 62 patients (82%) were returned to their previous ambulatory status. Intraoperative complications were as follows; distal crack (3 cases); rotation of femoral head (2 cases); entry point crack (I case); medialization of proximal fragment (7 cases); and missing of the interlocking screw (1 case). All of these complications did not affect the outcome. All medial cortical gaps were closed after sliding of lag screws. Three distal cracks did not propagate to the shaft. Postoperative complications were a case of superior cut-out, and two second fractures after falls. Callus formed more early in the stable trochanteric fractures (5+/-2.1 weeks) than unstable fractures (7.3+/-2.1 weeks). It was statistically significant. Union time between stable and unstable trochanteric fractures was not statistically significant. In conclusion, the Asian Pacific (AP) nail could appropriately fix the osteoporotic peritrochanteric fractures in elderly patient. It could offer early rehabilitation to these patients and decrease the mortality and morbidity.
