Attritional lesions of the wrist joint.

One hundred anatomic specimens of wrists were dissected to assess the incidence of perforations in the ligaments and triangular fibrocartilage of the wrist. The age of the specimen appeared to have a positive correlation with the incidence of perforations. There were no identifiable lesions in the wrists of specimens that were 45 years of age or younger. The incidence of perforations increased in specimens 60 years of age or older to 33% for the scapholunate interosseous ligaments, 27.6% for the lunotriquetral interosseous ligaments, and 27.6% for the disk of the triangular fibrocartilage of the wrist.
