Outcome of treatment of nonunion tibial shaft fracture by intramedullary interlocking nail augmentated with autogenous cancellous bone graft.

ABSTRACT

To assess results of operative treatment of non union fracture shaft of Tibia by intramedullary interlocking nail augmented with autogenous cancellous bone graft in our setup. A total of 25 nonunion tibial shaft fractures were evaluated among which 20 cases were male and 5 female with the mean age 31.84 years. Hypertrophic non-union were 14 and atrophic non union were 11. Upper one third of tibial diaphysis was involved in 4 cases, middle one third in 14 cases and lower one third in 7 cases. In all cases open reduction, interlocking nailing and autogenous cancellous bone graft was applied. The mean follow up was one year. Mean time for healing was 8.08 months. Mean operation time was 110 minutes (range 70 to 160 minutes). Satisfactory results (excellent and good) were achieved in 88% cases and unsatisfactory (fair and poor) results in 12% cases. This operative treatment option appears to have a high success rate and should be considered in nonunion of tibial diaphysis.
