Between 1982 and 1986, 60 tibial shaft fractures were treated by interlocking nailing. Of these, 10 were complicated by a pseudarthrosis. The results were assessed after a minimum follow-up of 2 years and were found to be good both in patients with fresh fractures and with pseudarthroses; in only 3 out of 60 cases was the outcome poor. The advantages of the techniques include: its suitability for virtually all types of shaft fractures ease of surgery early mobilization and weightbearing, with a low risk of infection rapid consolidation. Relative drawbacks are: radiation exposure longer preoperative preparation involvement of the entire shaft if infection develops irritation of the patellar tendon.
