Etiology of Carpal Tunnel Syndrome in a Large Cohort of Children

(1) Background: Carpal tunnel syndrome (CTS), a compressive mononeuropathy of the median nerve at wrist, is rare in childhood and occurs most frequently due to secondary causes. (2) Methods: Medical history, electrodiagnostic findings, imaging data patients with CTS from two pediatric neuromuscular centers were analyzed retrospectively. The etiology was investigated compared literature. (3) Results: We report on cohort 38 (n = 22 females, n 29 bilateral, mean age diagnosis 9.8 years). Electrodiagnostic studies all revealed slowing antidromic sensory or orthodromic mixed conduction velocities across carpal lack action potential and/or prolonged distal motor latencies. Median ultrasound diagnostic for confirmed tumorous vascular malformations. Etiology 29; 76%), mucopolysaccharidosis frequent underlying condition 14; 37%). Idiopathic this 9; 24%). (4) Conclusion: Since predominantly caused by an disorder, thorough evaluation search causative recommended group.
