Abstract

PURPOSE: To assess the evaluation of prognostic factors according to union time after unreamed femoral nailing.
MATERIALS AND METHODS
From Mar. 1998 to Mar. 2002, 53 cases of bone healing were analyzed among the fifty-nine femoral shaft fractures were treated with unreamed femoral nail (AO, UFN) and had been followed for more than 12 months. Clinical bone healing time was analyzed by Kempf's method and were evaluated prognostic factors according to union time.
RESULTS
Mean duration of the bone healing time was 18.7 weeks. According to Denker's classification, functional results were seen over satisfactory at all cases. Bone healing time was more faster at the low communition group than high communition group at 18.1 weeks. At the middle portion, bone healing time was fastest. Closed reduction cases were more faster than open reduction cases at 17.9 weeks. Bone healing time was faster that fracture was more close distance from isthmic portion. Bone healing time was not influenced age, isthmic ratio, operation time, associated injury.
CONCLUSION
All cases were unioned within 5 months without severe complication. That was seen faster bone healing time, in that low communition, more close distance of fracture from the isthmic portion, closed reduction method.
