Correction of angular deformities of tibia by using ilizarov external fixator

Abstract EN

Background: Angular deformities of the tibia in the frontal plane and to less extent in the sagittal plane lead to mechanical axis deviation of the lower limb and malorientation of the joints above and below the level of deformity.

Accurate correction of these deformities is important for functions and to prevent joint degeneration.

This work study the results of correction of theses deformities by Ilizarov external fixator.

Material: from 2006 to 2008, 25 patients with angular deformities of tibia were treated by Ilizarov external fixator, ninteen were post traumatic, three were congenital psudoarthrosis tibia and three with post ricketic deformities.

Fifteen deformities were is oblique plane, while 6 in frontal plane and 4 in sagittal plane.

The total degree of deformities was 810°, with associated tibial shortening in 10 patients.

Results: The mean duration of correction of deformities was 33.4 days.

Complete correction was achieved in 21 cases, percentage of correction was 99.1 % percentage of lengthening was 90% functional results were excellent in 12 cases and good in 13cases.
