Atavistic epiphysis: A bone that is independent phylogenetically but is fused with another bone in humans. These types of fused bones are called atavistic, e.g., the coracoid process of the scapula, which has been fused in humans, but is separate in four-legged animals.
Atavistic muscles in several birds [21] [22] and mammals such as the beagle [23] and the jerboa. [21] Extra toes in guinea pigs. [3] [24] Reemergence of sexual reproduction in the flowering plant Hieracium pilosella and the Crotoniidae family of mites. [25] Webbed feet in adult axolotls. [26]
At the end of the formation of the secondary ossification center, the only two areas where the cartilage remains is at the articular cartilage covering the epiphysis and at the epiphyseal plate between the epiphysis and diaphysis. [3] A schematic for long bone endochondral ossification: [4]

Type V – A compression fracture of the growth plate (resulting in a decrease in the perceived space between the epiphysis and metaphysis on x-ray): [11] 1% incidence Type VI – Injury to the peripheral portion of the physis and a resultant bony bridge formation which may produce an angular deformity (added in 1969 by Mercer Rang) [ 12 ]
