Retrograde nailing for subtrochanteric femur fractures.
This study reviews the results of subtrochanteric femur fractures treated with a retrograde nail at a level 1 trauma center. Sixteen patients with 17 fractures were followed up until union. The average Injury Severity Score (ISS) was 19, and average knee range of motion was 127 degrees. Four patients required dynamization of their nail, and three healed over a prolonged period of time. Two patients required exchange nailing: one after failure of union after dynamization and one with a broken nail that was revised to an antegrade nailing. The average varus deformity was 5.06 degrees and only 35% of fractures healed in greater than 5 degrees of varus, with an average time to union of 22.4 weeks (range, 6-54 weeks). Antegrade nailing remains the treatment of choice for the vast majority of subtrochanteric femur fractures. However, retrograde femoral nailing may be an effective treatment option for some subtrochanteric fractures in a selected group of patients.
