Objectives: We evaluated the effectiveness of a new inflatable intramedullary nail system in the treatment of tibial and humeral fractures.
Methods: The study included seven patients (4 men, 3 women; mean age 37.5 years; range 27 to 48 years) whose humeral or tibial fractures were treated by new inflatable intramedullary nails. Five fractures were in the tibial diaphysis; three were humerus fractures. One patient had bilateral involvement. All tibial fractures and one humeral fracture were fresh, whereas two patients presented with delayed union. Treatment consisted of closed reduction and antegrade intramedullary nailing, with the addition of bone grafting in delayed unions. The patients were evaluated with regard to operation duration, healing periods, complications, and final clinical and radiologic findings. The mean follow-up period was 15.3 months (range 12 to 20 months).
Results: Operation time for both tibial and humeral fractures was less than that with other internal fixation techniques. The need for fluoroscopic monitoring decreased appreciably, as well. Healing times were similar to those of other intramedullary nailing systems. No complications occurred related to the use of the inflatable intramedullary nail system.
Conclusion: The use of inflatable intramedullary nails may have significant implications in selected fractures, allowing easier stabilization of long bone fractures and saving valuable operation time.
