[Simultaneous occurrence of trigger fingers and carpal tunnel syndrome]

We report an unusual case of trigger fingers and carpal tunnel syndrome occurring simultaneously; both conditions were caused by space-occupying fibrosis of the flexor tendon sheath. Following operation the patient was relieved of his symptoms. In case of simultaneously occurring trigger fingers and carpal tunnel syndrome, one should be aware that both conditions can be caused by space-occupying lesions beneath the carpal tunnel. Endoscopic surgery should be avoided in these cases.
