DISLOCATIONS OF CARPAL BONES 769 The diagnosis is made hj recognition of the bone under the flexor ten-dons and of the gap on the dorsum between the os magnum and radius. In some uncomplicated cases reduction has apparently been affectedby manipulation, but in a number of them (Codman, Hildebrandtjlater examination showed that reduction had been incomplete or thatthe displacement had recurred. It is, I think, evident that the sur-geon cannot be certain that he has fully reduced or that the bone willremain in place, and as removal of the bone has given as good func-tional results as reduction has, the surgeon is justified, I think, inresorting to removal at once. Nevertheless, late removal se
