There are several distinct ulnar-sided wrist impaction and impingement syndromes. Underlying anatomical causes exist for each syndrome, however, repetitive or excessive use of the forearm and wrist can also contribute.
- ulnar impaction syndrome: positive ulnar variance
- ulnar impingement syndrome: acquired short ulnar
- ulnar styloid impaction syndrome: long ulnar styloid or styloid nonunion
- hamatolunate impingement syndrome: type II lunate morphology (presence of an articulation between lunate and hamate)
