Open tibial fractures: faster union after unreamed nailing than external fixation.
Unreamed intramedullary nailing is an alternative to external fixation in the treatment of open tibial fractures. We compared a prospective series of thirty-one patients managed with a solid nail with static interlocking without intramedullary reaming, with a retrospective series of thirty-one patients managed by external fixation. The protocol for soft tissue treatment was the same throughout the study period. Most fractures were caused by high energy trauma and included Grade I to III B injuries. The fracture wound infection rate was equal in both groups; there were two deep and three superficial infections in the nail group and three deep and two superficial infections in the external fixation group. In addition, eleven patients in the external fixation group had severe pin track infections. The mean time to union was five months in the nail group and eight months in the external fixation group. The incidence of delayed union was twice as high in the external fixation group as in the nail group. The number of surgical procedures performed to promote union was three times higher in the external fixation group. The malunion rate did not differ between the groups. Although the treatment groups are not fully comparable, the results indicate that intramedullary nailing is superior to external fixation in the treatment of most open tibial fractures.
