Lesions of the triangular fibrocartilage in fractures of the wrist.

MRI conducted in 32 cases of distal fracture of the radius a mean of 93 days after trauma allowed for the identification of various lesions of the soft tissues among which those of the triangular fibrocartilaginous complex. These observations confirm the presence of lesions of the triangular fibrocartilaginous complex (TFC) among immediate complications of distal fractures of the radius and the diagnostic role of MRI in post-traumatic ulnar pain.
