Is a Plantarflexed First Ray the Primary Deformity In Children With Cavovarus Feet Secondary to Charcot-Marie-Tooth Disease? A Pedobarographic Analysis

In this cohort, dynamic pedobarography did not consistently demonstrate the first metatarsal contact occurring before the fifth metatarsal contact in children with varus feet secondary to CMT. While nearly 40% of the feet did make initial contact on the first ray, 60% of the feet landed in varus before the first ray made contact, leading us to believe that the foot is prepositioned in varus. This may be in part due to the progressive muscle imbalance and secondary deformity that has occurred. Surgical management of these children should take this possibility into consideration and focus on rebalancing the forces causing this varus positioning as well as correcting the resultant bony deformity.
