Intramedullary nails were placed prospectively in 25 acute femoral shaft fractures in 25 patients without the use of a fracture table. A femoral distractor was used in 21 of the 25 patients to aid in obtaining and holding a reduction. Our goals were to determine if the technique was safe and effective for insertion of intramedullary nails in a wide spectrum of femoral fractures--with no increase in morbidity when compared to the use of the more familiar fracture table--and to determine the potential complications and pitfalls of using this technique. A retrospective evaluation of the most recent 25 patients with 27 femoral fractures that underwent intramedullary nailing on a fracture table was done to compare operative time, estimated blood loss, complications, and postoperative fracture alignment. In addition to the clinical evaluation, cadaveric dissections were undertaken to determine the exact location of the proximal distractor screw in relation to the contents of the femoral triangle. The femoral nerve was a minimum of 2.5 cm, and the femoral artery a minimum of 3.0 cm from the proximal screw. In comparing the two studies, no significant difference was noted in the age of the patients, fracture types or locations, associated injuries, operative time, estimated blood loss, final fracture reduction, or nail position. No complications were encountered in the placement of the proximal femoral distraction screw. Although the distraction method is technically difficult because the reduction is obtained entirely during the procedure, there are certain situations when this technique could be employed with the benefit of decreasing intraoperative patient manipulation, thereby shortening operative time.(ABSTRACT TRUNCATED AT 250 WORDS)
