The authors reviewed 104 feet from 52 consecutive children with hereditary motor and sensory neuropathy (HMSN) seen for the first time in clinics in two pediatric institutions between 1996 and 2003. Sixty-nine feet had a cavovarus deformity, 23 feet had a planovalgus deformity, and 12 feet had no significant deformity. All cases with deformity had bilateral involvement, and of those with deformity, only 45% had symmetric involvement. In HMSN I, III, IV, V, and X-linked HMSN, cavovarus was the most common deformity. However, in HMSN II, 55% of feet had a planovalgus deformity, 36% had a cavovarus deformity, and 9% had no deformity. In all, 43 feet underwent surgery of some type. Surgery, and in particularly combined bony and soft tissue procedures, was performed much more frequently on feet with cavovarus than planovalgus deformities. Soft tissue surgery alone was performed at an earlier age than combined bony and soft tissue surgery.
