Ulnocarpal Impaction Treatment in Wayne, Paramus, and Parsippany NJ

Ulnocarpal impaction occurs when the distal ulna and carpal bones, primarily the lunate, bump into one another and cause pain. This may be caused by positive ulnar variance, radial shortening from a previous distal radius fracture or ligament tears. Pain is usually on the pinky side of the wrist and is worse with activities that cause ulnar deviation of the wrist. Radiographs may show positive ulnar variance, meaning the ulna bone is higher than the radius, and possibly sclerosis of the lunate bone or ulnar head from impaction. This also may predispose patients to TFCC tears. Conservative management consists of bracing and cortisone injections, although a surgical procedure may be the best option if pain and dysfunction persist.
