Unreamed intramedullary locking nailing for open tibial fractures

We reviewed the results of the treatment of 24 cases of open tibial fractures using unreamed intramedullary locking nailing. The fractures were classified, following the Gustilo system as grade I-7, grade II-7 and grade III-10. The average time to achieve bony union was 22 weeks with a 26% incidence of pseudoarthrosis. There were no cases of deep infection. Five cases healed with shortening of over 1 cm, but we did not observe angular deformity in any of the patients. In 2 fractures with associated articular lesions, joint motion was limited at final follow up. The nail broke in 2 cases and the screws in 5. The surgical procedure is well tolerated by patients, allows good management of soft tissue lesions and rehabilitation with low rate of infection and malunion. The main disadvantages have been the relative high incidence of nonunion and breakage of metal.
