Emergency management of type IIIB open tibial fractures.

We present our therapeutic strategy for the treatment of type IIIB open tibial fractures. It involves emergency internal stabilisation of the bone by locked intra-medullary nailing when appropriate and skin cover using either a pedicled or free muscle flap. Where there is bone loss, a cancellous iliac graft is performed at the same time. Eighteen cases of type IIIB open tibial fractures treated between 1986 and 1995 were analysed. There were 17 men and 1 woman; the average age was 35 years. Each of the 18 patients underwent wound debridement as a primary emergency procedure with no secondary reoperation. Bone fixation was performed by locked intra-medullary nailing (AO nail, How Medica) 6-10 h after trauma. A primary cancellous iliac bone graft was performed in three cases. Cover was applied immediately after nailing (muscular pedicle flaps in 12 cases, muscular free flaps in 6 cases). Local flap cover led to two failures: both these fractures were followed by postoperative complications. The 6 free muscle flaps were successful. The average time to bone union was 6.5 months (range: 3-18.5 months) according to clinical criteria and 9 months (range: 4-27 months) according to radiological criteria. Out of the 18 fractures, 13 were primarily united (72.2% of cases); 3 involved osteitis and 2 nonunion. Sixteen patients were examined again with a mean follow-up of 4.8 years (range: 1-11 years). Six moderate malunions occurred; none needed surgical reoperation. Ankle motion was normal in 7 cases and reduced to below 50% in 9 cases when compared with the healthy ankle. Thirteen patients resumed their previous professional activities. This surgical strategy reduces bone union time, the number of operations and the time spent in hospital; it improves functional results.
