A specimen of a bipartite sesamoid bone revealed anatomic cartilaginous continuity in the presence of radiographic osseous discontinuity. Hyaline cartilage present between the two ossific foci strongly supported the bipartite ossification process as a developmental variation.
一块二分籽骨标本显示，在X线片上存在骨连续性中断的情况下，其解剖学上的软骨是连续的。两个骨化中心之间的透明软骨有力地支持了二分骨化过程是一种发育变异。
