O1092 DEFORMITY CORRECTION AND LENGTHENING IN CONGENITAL POSTEROMEDIAL BOW



Abstract

Aims: To review the presentation, progression, treatment, and outcome of congenital posteromedial bow of tibia. Methods: Seventeen patients were studied using radiographs and medical records retrospectively. The time period was from 1989 to 2002. Data was collected with special reference to deformity correction and lengthening. Complications were analysed. Results: Eight of the patients were male and nine female; eleven of them had deformity correction and lengthening, whereas two are awaiting surgery, two underwent contralateral epiphysiodeses and one, periosteal stripping. Twelve were treated with the Ilizarov device, seven with LRS. The range of discrepancy pre – operatively was from 3 to 8.8 cm. Mean length gained was 3.7 cm with residual discrepancy within 0.6 cm. Complications noted were minor grades of infection and 3 patients required further corrective surgery. The bone-healing index was 62 days per cm. There was some decrease in ankle movement noted, this was unchanged or improved post-operatively. Conclusion: Successful simultaneous deformity correction and lengthening for this condition is possible. The Ilizarov frame provided more benefits in reducing complications. This is the largest series of lengthening and correction of this deformity published and the residual deformity and initial length discrepancy is greater than previously stated.
