Study cites four-corner arthrodesis as effective treatment for arthritic wrists

By Monica Jaramillo

Recently published data indicated four-corner arthrodesis with circular plate fixation is effective for the treatment of wrists with degenerative arthritis.

Researchers retrospectively evaluated 36 male patients with a mean age of 48 years who underwent four-corner arthrodesis for either scapholunate advanced collapse or scaphoid nonunion advanced collapse. Patients were followed for an average for 56 months. Investigators evaluated functional outcomes including VAS pain score, range of motion, grip strength and DASH score. A handheld goniometer was used to measure wrist motion.

Radiographs were evaluated for arthrosis presence, nonunion, hardware failure and dorsal impingement. Data also collected included work status, bone union status, complications and reoperations.
