Wrist stability after experimental traumatic triangular fibrocartilage complex lesions

The 1A lesion does not alter significantly wrist stability and hence the common treatment by a two-third excision of the central part of the disk will not affect wrist stability. A 1C lesion alters significantly the stability of the wrist. At 35° of wrist extension forced radioulnar deviation and forced internal/external rotation were altered significantly; this might be used in a clinical test for a 1C lesion. The rotation of the forearm has no influence on the outcome.
