Abstract
This single-centre retrospective study reports our management of carpal tunnel syndrome in 52 children (103 hands) with mucopolysaccharidoses and mucolipidoses. All except one were bilateral. The median age at surgery was 4 years (range 1.5 to 12). The diagnosis of carpal tunnel syndrome was confirmed by an electromyogram (EMG) in all patients; 38% of these presented without any clinical signs. Surgical neurolysis was performed in all hands, combined with epineurotomy in 52 hands (50%) and flexor tenosynovectomy in 75 hands (73%). Surgery was bilateral in 98% of children (102 hands). The mean follow-up was 12 years (range 1 to 19) and the EMG was normalized in 78% of hands. Ten patients suffered recurrence, eight of whom required further surgery. Screening for carpal tunnel syndrome is essential for the management of children mucopolysaccharidoses and mucolipidoses. Surgical treatment should be carried out early with follow-up by EMG to detect recurrence.
