Talectomy for the Management of Resistant Talipes Equinovarus Deformity; Does Adding Ilizarov External Fixator...

The management of resistant talipes equinovarus (TEV) is challenging. Residual deformity and recurrence are among the most feared complications. This study was conducted to evaluate the effectiveness of talectomy in the management of arthrogrypotic TEV and to investigate the value of adding a simplified Ilizarov fixator (SIF).

A total of 42 resistant TEV feet among 23 arthrogrypotic children were operated between January 2012 and 2016. The average age was 6.7 ± 1.67 years. The feet were divided into 2 groups; group A (Casting group) included 20 feet (11 children) that were managed by talectomy and casting, while group B (Fixator group) included 22 feet (12 children) that were treated using a SIF concomitant with talectomy. The results were evaluated morphologically by Dimeglio grading system and functionally by Legaspi system.

The average follow-up was 36.62 ± 3.88 months. With the numbers available in this study, there was significant improvement (p ≤ .05) in the Dimeglio scores in both groups, which was significantly more evident (p ≤ .05) among the fixator group. The majority of the good functional results were reported among the fixator group, while the poor feet were observed mainly in the casting group (p ≤ .05). The functional end results were significantly affected (p≤ .05) by the final Dimeglio scores. The age had also statistically significant effect (p≤ .05) on the functional end results in group A only.

Talectomy is an effective procedure for salvaging arthrogrypotic TEV. Supplementation of the procedure by SIF was associated with more satisfactory morphological and functional results particularly in older children.
