Carpal tunnel syndrome in black South Africans.

The incidence and the aetiology of chronic carpal tunnel syndrome in black South Africans was evaluated. This study showed that the incidence of idiopathic carpal tunnel syndrome was very low in this population group and that most patients who presented with symptoms and signs of chronic carpal tunnel syndrome had a specific pathology. A rare case of tumoral calcinosis causing carpal tunnel syndrome is presented. A case of perineural lipofibroma causing carpal tunnel syndrome is also described.
