Abstract
|
|
|
Purpose: We analyzed the complications of femoral peritrochanteric fractures treated with the Gamma nail to reduce its complications.
Materials and Methods: We evaluated the complications among the 96 patients who were treated with the Gamma nail from January 2000 to May 2005. Mean follow-up period was 17.8 months and mean age was 75.2 years. We analysed the relationship between the complication and the fracture pattern, postoperative reduction status, position of the lag screw, bone density, displacement and tip-apex index (TAD).
Results: The complications were presented in 12 cases (12.5%). Cut-out of lag screw were in 5 cases, varus deformity with short lag screw in 2 cases, metal breakage of distal screw in 1 case, breakage of drill bit intraoperatively in 1 case, superficial infection in 2 cases and deep infection in 1 case. 5 cases (4.2%) were required reoperation. All of the cut-out of lag screw showed increased TAD (tip apex distance) above 25 mm.
Conslusion: To reduce the complications of the Gamma nail, we need exact surgical technique, good positioning of the lag screw and choice of appropriate length for the lag screw.
