According to Scheuer and Black (25), when fusing, the palmar border of the proximal epiphysis develops a medial and lateral tongue of bone that grows upward toward the diaphysis. The dorsal surface responds differently by forming a sloping distal metaphyseal surface, which is convex dorsopalmarly. The fusion of the distal phalangeal epiphysis occurs at the age between 13.6 and 16 years, depending on the sex (34). Since both the semiannular dorsal surface of the diaphysis and the dorsal part of the proximal articular fragment present rounded borders that are consistent with the epiphysis fusing at the time of death (Fig. 3A) and since it takes between 2 and 4 months for an epiphysis to complete the process of fusion, once started, we concluded that the dimensions of the phalanx are close to its final mature state (25).
