Anatomical and roentgenographic studies of TFC were performed using 24 cadaver's wrist joints.
Perfortion of TFC was observed in 11 cases (46%) consisting of 3 cases with ulnar plus variance, 5 cases with neutral variance, and 3 cases with minus variance. In spite of ulnar minus or neutral variance, if radial inclination is high, the carpal bone gets ulnar translocation, so TFC perforation results from ulnar abutment.
Cartilaginous changes were most frequently seen on the lunate in cases where the TFC had perforated, but roentgenographic changes were not observed. If radiographic changes are observed, they are signs of TFC perforation.
