Objective To evaluate the results of the treatmenton femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail . Methods From Jun. 1999 to Sep. 2003, 74 patients with femoralfractures were treated by intramedullary interlocking nail (inverse limited marrow cavity rasping) .There were 62 males and 12 females. Among them, 5 caseswere type 32A1, 7 cases were type 32A2, 12 cases were type 32A3, 35 cases were type 32B2, and 15 cases were type 32C2. Results Seventyfour patients were followed up for 13 to 29 months(15.4 months in average). Thetime for fracture union ranged from 3 to 5 months(3.8 months in average). The overall rate of excellence was 98.7% by Wuyuesong grading. There was 1 case of non-union, 1 case of delayed infection, and 2 cases of bent screw. Conclusion The treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail is easy to operate and has minimum impairment to local circulation.
