RESUMEN
Sixty-five fractures of the distal end of the femur in 64 patients were analyzed to compare results of open and closed methods of treatment. Fractures were classified using the new AO-ASIF system which provides an adequate description of the distal femoral fractures. The rating system of Neer et al. Was used for evaluation of the end-results. The 44 patients [45 fractures] treated with internal fixation according to the AO recommendations-had an overall 80% excellent to satisfactory result, an average time to union of 4.3 months, and average knee motion range of 110.3 degrees. There were 3 postoperative infections, one nonunion, and no malunion. The 20 patients treated conservatively had an overall 65% excellent to satisfactory result, an average time to union of 5.4 months, and an average ranged of knee motion of 64.5 degrees. There were 3 D.V.t.; 2 nonunions, and 2 malunions. Conservative treatment is still an acceptable treatment modality, with good functional results in many of these fractures
