The Intramedullary Expanded Self-locking Nail for the Treatment of Femoral Shaft Fracture

Objective To investigate the curative effects of intramedullary expanded self-locking nail (IESN) in the treatment of femoral shaft fractures. Methods Forty-three cases of femoral shall fractures were treated with open nailing procedure. Of these 43 cases, 38 fractures were fresh in the upper third, me dian third and lower thick of the femoral shaft. The remaining 5 were old fractures, of which 2 were in the upper, 3 in median and lower third (1 oblique fracture, 4 transverse following the failure of internal fixation). Results After 7 to 25 months (average 13. 4 months) follow-up all of the fractures had union and the overall excellent rate was 97. 7% according to Klemm grading. Conclusion IESN is well designed, easy to operate and X - ray monitoring is not neccessary during the procedure. The correct usage of IESN has the advantages of resisting curvature, torture and shortening of fracture. The minimum impairment to local circulation help to Promote the healing.
