Rupture of a flexor pollicis longus tendon in Scheie's syndrome. Case report.

We describe a case of Scheie's syndrome with a closed rupture of the flexor pollicis longus tendon, probably caused by a combination of extrinsic and intrinsic tendon changes. Early detection of carpal tunnel syndrome in all patients who have some form of mucopolysaccharidosis in which this is a universal occurrence (such as Scheie's syndrome), is recommended. Release of the carpal tunnel prevents long term complications, as described in this case report.
