Congenital carpal tunnel syndrome

Area of Science:

• Orthopedics
• Neurology
• Genetics

Background:

• Congenital carpal tunnel syndrome (CCCTS) is a rare condition.
• Melorheostosis is a benign bone overgrowth disorder.
• This case presents a unique association between CCCTS and melorheostosis.

Observation:

• A patient presented with congenital hand dysfunction since birth.
• Symptoms included hypotrophy of median nerve-innervated fingers and thenar muscle atrophy.
• Severe median nerve degeneration within the carpal tunnel was observed.

Findings:

• The study describes a rare case of congenital carpal tunnel syndrome.
• The condition was associated with melorheostosis, a bone disorder.
• Sural nerve grafting successfully treated the median nerve degeneration.

Implications:

• This case highlights a potential link between melorheostosis and congenital carpal tunnel syndrome.
• Sural nerve grafting is a viable treatment for severe median nerve degeneration in CCCTS.
• Further research may elucidate the underlying mechanisms of this association.
