Abstract
Purpose of study: We aimed to compare the efficacy and effect of Ender nail and unreamed interlock nail in the management of Type I, II and IIIA fractures.
Methods: 33 cases of open tibial shaft fractures in 32 patients were included in this prospective study. 17 tibial fractures were fixed with Ender nails introduced by antegrade approach and 16 tibial fractures were fixed with statically locked Interlocking nails. The mean follow-up period was 17.8 (6 to 32) months. The mean injury-surgery interval was 5.6 (1 to 16) days.
Results: In the Ender nail group, the average union time for open fracture was 19.5 weeks and 18.3 weeks for Type-I fracture. In the Interlock nail group, the average union time for open fracture was 24.8 weeks and 23.8 weeks for Type-I fracture. Mann-Whitney test revealed significant difference between the two groups for the data described above. Treatment with either nails showed no significant difference in union time for Type-II and type-IIIA fractures. Ankle movement restriction was noted more in interlock nail group (p = 0.04). Anterior knee pain, chronic osteomyelitis and breakage of distal screw were observed in interlock nail group. No complication was seen in Ender nail group.
Conclusion: Ender nailing is a safe and effective choice for treatment of open tibial shaft fractures due to faster fracture union rate and fewer complications. Ender nail is a good implant in treatment of open tibial shaft fractures especially in regions with limited access to specialized, sophisticated and expensive facilities.
