Carpal tunnel syndrome in children.
CTS is uncommon in children. A number of conditions predispose children to developing CTS. These conditions include the lysosomal storage diseases, a multigenerational history of CTS, and macrodactyly. Because many case are idiopathic, isolated cases are possible even in the normal child or adolescent. Children with CTS often have modest complaints in spite of long-standing difficulties such as decreased manual dexterity in one hand or poorly localized pain. Physical findings tend to be dramatic abnormalities such as severe thenar weakness and atrophy. These findings suggest that many children are diagnosed late in the course of their nerve compression. Because some patients have profound atrophy at a young age, the condition can be confused with primary thenar hypoplasia. Provocative tests, the Tinel and Phalen tests, are often normal in children with long-standing nerve compression. Electrodiagnostic studies are essential to establishing the diagnosis in many children. Pediatric cases of CTS tend to demonstrate bilateral electrophysiologic abnormalities, even if only one hand is primarily involved clinically. Therefore, it is recommended that EMG and NCS be performed bilaterally in all suspected children. Sedation may be helpful in obtaining electrodiagnostic studies in a small child. Open operative release is the only treatment documented to be effective in the treatment of childhood CTS.
