Of all the various neuropathies seen in rheumatic diseases, entrapment neuropathies are most common and among these carpal tunnel syndrome is the commonest. Entrapment of the median nerve by swelling from synovitis or other damage to the wrist joint can lead to this complication. The carpal tunnel is bounded by the carpal bones and the transverse carpal ligament (flexor retinaculum). Through this tunnel pass the flexor tendons of the hand along with the synovial sheaths covering them. The median nerve passes superficial to these tendons but deeper to the thick fibrous flexor retinaculum. In view of the nerve being surrounded by tight structures, swelling from collection of fluid, synovitis, scarring, disorganization of the joints with or without dislocation of the bones can cause impingement of the nerve and give rise to symptoms. Although among the rheumatic diseases, rheumatoid arthritis is the most common cause of the carpal tunnel syndrome. Other conditions can also give rise to it.🏁
