The end portion of a long bone in vertebrates.



the jointed end of a tubular bone. The epiphyseal cartilage (known as growth plate) found between the epiphysis and the diaphysis plays a major role in the growth of bone lengthwise, becoming ossified between the ages of 12 and 25 years.

Injury to the epiphysis in childhood or adolescence may cause epiphysiolysis—that is, displacement of the epiphysis and rupture of the epiphyseal cartilage, which may slow down the bone’s growth and result in its shortening. A more frequent condition is osteoepiphysiolysis, in which the fracture line extends to the diaphysis as well.

Moreover, giant cell tumor of bone affects the epiphyseal ends of the skeletally mature patient, as opposed to NOF, which never affects the epiphysis.
Dietary protein has to be highlighted, as rats fed a 20% protein diet for 7 days had increased body growth, muscle growth, epiphyseal cartilage width and epiphysis length compared to a 5% protein diet group.

It has the additional benefit of triggering a biologic reaction that accelerates revascularization of the epiphysis to shorten duration of the active stage.
This must have occurred while the ligaments in the shoulder were intact, since the humerus with the proximal epiphysis and the scapular epiphysis were in anatomically correct positions.

Meyer and colleagues (3) studied the arterial supply of six fresh frozen proximal humeri and found that the epiphysis received contributions from both the anterior and posterior circumflex humeral arteries.
The predominant radiologic findings include triangularization of the distal radial epiphysis with shortening of the ulnar segment, dorsal dislocation of the distal ulna that cannot be easily reduced, pyramidalization of the distal carpal row, shortening and bowing of the distal radius, and widening of the distal radioulnar joint.
