Retrograde Intramedullary Interlocking Nailing in Fractures of the Distal Femur: A Review of 20 Cases with an Average Follow-Up of One Year (original) (raw)

Journal of Medical Research and Surgery

Abstract

Objectives: In patients with distal femur fractures, we studied the role of retrograde locked intramedullary nails. Methods: Retrograde locked intramedullary nailing was used to treat the distal femur fractures of 20 patients (15 males, 5 females; mean age 47 years; range 25 to 69 years). Two patients had fracture of the distal femur and shaft. The fractures were classified as A1 (n=12), A2 (n=6), A3 (n=2), by the AO classification. There were two Grade I open fractures and 18 closed fractures. Three fractures were managed with percutaneous technique. At the mean first follow-up time of 18 months (range 15-48 months and mean second follow up at 27 months (range 12 to 68 months), the concluding functional results were assessed by using the modified Hospital for Special Surgery (HSS) knee assessment scale. Results: The average time to achieve union was 24.2 weeks (range 14 to 42 weeks). One patient had a delayed union (44 weeks). Five knees (25%) had normal joint range of motion, ten ...
