Purpose
The aim of the study was to evaluate the role of joint hyperlaxity (by Beighton score) as a protective factor for clubfoot relapse.
Methods
Patients with idiopathic clubfoot treated with the Ponseti method between January 2004 and December 2012, without other congenital foot deformity, and not previously treated by open surgery were included in either the Relapse group (n = 23) if it was a clubfoot relapse or the Control group (n = 19) if no relapse was noted. Joint laxity was evaluated using the Beighton score at the latest follow-up against the Normal group (n = 22, children matched by sex and age without clubfoot deformity).
Results
We found a significantly higher joint laxity in the Control group (4.58, 95% confidence interval [CI]: 2.1–7.06) as compared to the Relapse (3.17, 95% CI: 1.53–4.81, p = 0.032) and Normal (3.14, 95% CI: 1.78–4.5, p = 0.03) groups. The univariate logistic regression showed a 5.28-times increase in the risk of relapse for a Beighton score lower than 4/9 points (odds ratio = 5.28; 95% CI = 1.29–21.5; p = 0.018).
Conclusions
Joint hyperlaxity could be a protective factor for clubfoot relapse.
