[Pes valgoplanus in Friedreich and Charcot-Marie-Tooth-Hoffmann disease]

Insights
Friedreich's hereditary ataxia and Charcot-Marie-Tooth disease can present with extreme pes planovalgus in infancy, not just severe hollow foot deformities. This finding is crucial for early diagnosis of these neurological conditions.
Area of Science:
- Neurology
- Orthopedics
- Genetics
Background:
- Friedreich's hereditary ataxia (FA) and Charcot-Marie-Tooth disease (CMT) are progressive neuromuscular disorders.
- Hollow foot deformity (pes cavus) is a recognized, often severe, characteristic of advanced stages of FA and CMT.
Observation:
- Personal observations suggest that infants with FA or CMT may present with extreme pes planovalgus (flat, everted feet).
- This contrasts with the typical presentation of severe pes cavus in later disease stages.
Findings:
- A retrospective analysis indicates that pes planovalgus in infancy can be an early sign of FA or CMT.
- This early foot deformity may be overlooked in the differential diagnosis of pediatric foot conditions.
Implications:
- Considering FA and CMT in the differential diagnosis of infantile pes planovalgus can lead to earlier diagnosis and intervention.
- Recognizing this atypical early presentation can improve patient outcomes for these progressive neurological diseases.
Abstract:
An increasingly severe hollow foot deformity is typical of Friedreich's hereditary ataxia and Charcot-Marie-Tooth's progressive muscular atrophy. However, on the basis of personal observations it has been found that in infancy, patients with either of these diseases may have an extreme pes valgoplanus. The retrospective analysis presented here is intended to draw attention to this possibility and to point out that these diseases should also be taken into consideration in the differential diagnosis of the cause of a pes valgoplanus.
