CLINICAL VS. FUNCTIONAL OUTCOME OF RELAPSE SURGERY IN SEVERE CONGENITAL TALIPES EQUINOVARUS



Abstract

From a cohort of 110 idiopathic clubfeet, 26 feet in 18 children requiring surgery for severe relapse have been studied. Surgery was comprised of a lateral column shortening procedure (Lichtblau) plus or minus a plantarmedial release. Surgery was staged to avoid wound complications.

Pre-operatively, feet were prospectively categorised into one of four grades according to a system reported by Dimeglio. Children were reviewed on two subsequent occasions. At review, feet were again graded. In addition, appearance and functional outcome was analysed and included an assessment of gait, activity and functional limitation.

Three children were lost to follow-up, leaving 22 feet in seven male and eight female patients available for review. The mean age at surgery was 43 months (23–82). The mean time from surgery to first and second reviews was 35 and 56 months, respectively.

There was a significant improvement in grading at first review compared to pre-operative grading (Wilcoxon signed ranks test). Although there remained a significant improvement in grading at second review compared to the preoperative grading, there was a significant reduction in the number of feet in which grading had improved when compared to first review.

There was no significant change in function between the two post-operative reviews (Chi-square tests), with the majority of children experiencing little functional limitation. There were no wound complications.

Relapse surgery, involving a lateral column shortening procedure for severe clubfoot, results in a significant initial improvement when assessed using a grading system. This improvement in grading subsequently decreases over time. However, the functional outcome in such cases remains favourable.
