The Ponseti technique for treatment for Congenital Talipes Equinovarus (CTEV) was
introduced in the authors' institution in 2001, substituting a more traditional
orthopaedic approach which involved surgery. There is currently limited published
information regarding the differences in clinical outcomes between these two
techniques, particularly in relation to plantar pressure analysis. This study
aims to determine differences in pedobarographic outcome in children with CTEV,
treated with either a surgical or Ponseti approach. A high resolution
pedobarograph was used to record plantar pressure distribution in 52 children
with CTEV and 26 children with typical development. Data were imported into
Matlab where a custom programme was developed for processing and analysing
pedobarographic recordings. There were significant differences in both treatment
groups compared to the typically developed group (p<0.05) for most measurements.
The most salient differences between treatment groups were (i) at the hind-foot
where the Ponseti group had significantly lower maximum peak pressures (p<0.05);
(ii) at the lateral mid-foot where children treated by the Ponseti approach
showed significantly larger peak force (p<0.001), average peak pressure (p<0.001)
and maximum peak pressure (p<0.01); (iii) at the lateral fore-foot where the
surgical group showed lower average peak pressure (p<0.05); and (iv) in the
medial/lateral fore-foot ratio where the Ponseti group showed significantly lower
values (p<0.05). Plantar pressure analysis is a complementary measurement for the
assessment of gait in children with CTEV. Data presented in this study showed
that while there were deviations in children with CTEV, the differences observed
between treatment groups suggest children in the Ponseti group have some level of
under correction or recurrence.
