Early ossification of the proximal pisiform with epiphyseal cartilage in non-human primates. Chimpanzee, gorilla, and orangutan early pisiform primary ossification centers within preserved cartilage (white dotted outline). Primary ossification centers are located dorsally within the cartilage model and within close proximity to the triquetral. Cartilaginous epiphyses (asterisk) have not yet started secondary ossification
