Ender rods versus external fixation in the treatment of open tibial fractures.

This is a retrospective nonrandomized study of 66 open tibial fracture patients that compares comparable population treated at one trauma center. The fractures were treated with either Ender rods or external fixation. Of these, 29 fractures were eliminated from the study due to incomparable variables. Thus, the study group consisted of a total of 37 tibial fractures: 20 treated by Ender rods and 17 treated by external fixation. Open tibial fractures treated with Ender rods had a significantly lower number of complications than those treated with external fixation. The group treated with Ender rods also had a significantly lower number of surgical procedures per patient in Grades I and II open tibial fractures. There were no statistical differences regarding weeks to union or hospital days. Ender rods are superior to external fixation removed early in the treatment of Gustilo's Grades I, II, and IIIA open fractures with either stable or unstable fracture configuration (Orthopaedic Trauma Association Grades IA-IC, IIA-IID, and IIIA-IIIC). Perhaps future study will allow sufficient numbers to determine whether Ender rods can be used in Grades IIIB and IIIC open tibial fractures, but there are no data at this time to support this conclusion.
