Carpal tunnel syndrome in chondrocalcinosis of the wrist. Clinical and histologic study.
Carpal tunnel syndrome (CTS) defined electromyographically was found in 8 of 22 unselected patients with chondrocalcinosis of the wrists (bilateral in 6, unilateral in 2). Thenar atrophy was the most frequently encountered clinical sign. In the hands with CTS, calcifications of the wrist were more extensive than in the hands, without CTS. Degenerative joint changes of the hands were significantly more frequent in the group suffering from CTS. Surgery was performed in 5 patients with CTS. Microscopic examination of the volar carpal ligament and the flexor synovial tendon sheath failed to reveal histologic signs of chondrocalcinosis. However, the presence of scarce crystals, as seen in polarized light as well as electron microscopy, suggests a minor form of chondrocalcinosis.
