Congenital perforations of the triangular fibrocartilage of the wrist.
A cadaveric study of the triangular fibrocartilage of the wrist in the foetus and infant revealed a high incidence of congenital perforation. In the second half of the study, wrist arthrography in foetal and infant cadavers with crown-rump length of more than 20 cm followed by dissection of the wrist joints showed good correlation between the two. In 60 cadavers there were 11 with bilateral perforations and five had unilateral perforation. This gave a total of 27 perforations in 120 wrist joints studied.
