Prospective Study of Gross Motor Milestones in Children with Severe Idiopathic Clubfoot Treated by Ponseti Method.

BACKGROUND

A prospective study of motor milestones achieved in severe clubfeet treated by Ponseti method and comparison between unilateral and bilateral clubfoot will help us gain further insight of motor milestones in these children.

METHODS

Prospective study of 150 consecutive children with idiopathic clubfoot who were treated by Ponseti method and in whom percutaneous tendoachilles tenotomy was performed. The gross motor milestones recorded were: rolls from back to stomach, sitting without support, standing with assistance, walks with assistance, standing alone, walking alone. This was compared with published regional and World Health Organization (WHO) normal data.

RESULT

15 patients were excluded due to non-compliance and recurrence. Children with unilateral clubfoot (80 children) and bilateral clubfoot (55 children) showed a delay of 0.2-2.1 months in various milestones, and this was statistically significant when compared with both normal data. 95% children with unilateral clubfoot had independent ambulation by 17 months and in bilateral ambulation by 17.8 months. There was also a statistically significant difference in unilateral and bilateral clubfeet in all variables except sitting without support and walking with support.

CONCLUSION

There is a delay in achievement in all children with clubfoot, with more delay in bilateral clubfoot as compared to unilateral clubfoot. The probable reasons could be plaster treatment, possible weakness due to tendoachilles tenotomy, use of orthosis or the inherent pathology associated with clubfeet. Parents hence need to be explained about this delay.
