Five Years Experience with the Orthofix Tibial Nailing System

Abstract

In the last decade interlocking intramedullary nailing has emerged as the most effective treatment for most tibial fractures. In this study we present our further experience with the Orthofix tibial nailing system, concurrently evaluating the easiness and safety of the distal targeting system for the distal locking. Ninety-seven fresh tibial fractures in the same number of patients with a mean age of 38.5 years (17-85) were treated. All operations were performed in a conventional operating theatre on a simple transparent operating table, with reduction of the fracture performed under manual traction and manipulation of the fracture site. In most of the cases closed reduction was achieved and conventional reaming performed. The mean duration of the operation was 30 minutes. The external targeting device failed in 12 distal locking screws. Fracture healing, confirmed clinically and radiographically, was observed at a mean of 17 weeks (12- 28 weeks). No tibial non-union necessitating reoperation occurred, however six fractures showed delayed union. All patients eventually gained a full range of motion of the knee and ankle joint and only twelve of them (13 %) complained of mild anterior knee pain. All patients returned to their previous activity. No mechanical failure of either the nail or the screws occurred. We believe that the Orthofix nailing system is a clinically effective system. Distal locking can be performed with ease without significant exposure to radiation, provided that the operative technique is accurately followed.
