Radial deviation of the finger caused by an occult intramuscular ganglion in a patient with rheumatoid arthritis.
Ulnar deviation is a common complication in patients with rheumatoid arthritis (RA). We report a case of an unusual radial deviation of the middle finger caused by an occult intramuscular ganglion of the second interosseous muscle (IOM) in a patient with RA. The resection of the ganglion did not resolve the problem, and the full range of motion of the metacarpophalangeal (MP) joint was achieved through dissection of the tendon of the second dorsal IOM.
