Ulnar Impaction Syndrome Ulnar impaction syndrome (UIS), also known as ulnar abutment or ulnocarpal impaction or loading, is a condition in which the ulna of the forearm is too long relative to the radius, resulting in excessive loading on the ulnar side of the wrist. Ulnar nerve release surgery is a procedure for cubital tunnel syndrome – also known as ulnar nerve entrapment. Cutibal tunnel syndrome is a condition in which nearby tissue puts pressure on the nerve inside the cubital tunnel, a narrow space through which the ulnar nerve passes around the elbow. Three procedures were identified as the most commonly used in treating this syndrome: ulnar shortening osteotomy, the wafer procedure, and the arthroscopic wafer procedure. Mean time to union and percentage nonunion for the osteotomy group was 10.3 weeks and 1.7%, respectively.

Ulnar impaction syndrome is a common cause of ulnar-sided wrist pain that is thought to be a result of abutment between the ulna and the ulnar carpus. Abstract: Ulnar impaction syndrome is abutment of the ulna on the lunate and triquetrum that increases stress and load, causing ulnar-sided wrist pain. Typically, ulnar-positive or -neutral variance is seen on a posteroanterior radiograph of the wrist. Ulnar Impaction Douglas M. Sammer, MDa, Marco Rizzo, MDb,* Ulnar impaction syndrome, also known as ulno-carpal impaction or ulnocarpal abutment, is a common source of ulnar-sided wrist pain.

In the ulnar neutral wrist, MRI can be helpful in the diagnosis by revealing signal changes and edema in the ulnar head, triquetrum, and lunate.
