Analysis of complications of intertrochanteric fracture treated with Gamma 3 intramedullary nail.

UNLABELLED Whether Gamma 3 fixation system is suitable for all intertrochanteric fractures is inconclusive. This paper analyzed the surgical complications of Gamma 3 intramedullary nail in the treatment of intertrochanteric fractures. METHODS A total of 186 cases were enrolled in the study including 115 males and 71 females. The surgical operations were performed in all cases and Gamma 3 intramedullary nail was inserted in medullary cavity. RESULTS Anti-rotation screw displacement into the intermuscular space of inner thigh occurred in 1 case, lateral femoral wall defect in 3 cases; refracture of proximal femur shaft during the Gamma 3 nail inserting into the medullary cavity occurred in 5 cases and fractures with a gap or malalignment in closed reduction of A3 type in occurred 6 cases. Fracture union occurred in 3-4 months postoperative. Recovery situations of all patients were evaluated based on Harris scoring system 6 with an average of 87 points. There are indications and shortcomings in the treatment of intertrochanteric fracture with Gamma 3 intramedullary nail. CONCLUSION Understanding the surgical indications, standardizing the operation and upgrading skills are the key points to ensure operation successful, reduce complications and improve clinical outcomes.
