Degenerative lesions are the result of chronic injuries that involve loading on the ulnar wrist; however, many of these lesions are asymptomatic. The lesions are divided into subcategories that progress from early TFCC wear to stage IV ulnar impaction syndrome. There is an association between patients with positive ulnar variance and degenerative defects of the TFCC. In addition, several studies have demonstrated an age correlation with lesions in the TFCC.
