The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. This replacement is known as epiphyseal closure or growth plate fusion. Complete fusion can occur as early as 12 for girls (with the most common being 14–15 years for girls) and as early as 14 for boys (with ...
The triradiate cartilage (in Latin cartilago ypsiloformis) is the Y-shaped epiphyseal plate between the ilium, ischium and pubis to form the acetabulum of the os coxae. Human development [ edit ]
The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.
Linear growth takes place in the epiphyseal growth plates (EGP) of long bones. [23] In the growth plate, chondrocytes proliferate, hypertrophy and secrete cartilage extracellular matrix. New cartilage is subsequently remodeled into bone tissue, causing bones to grow longer. [24]
Acromegaly is a hormonal disorder that occurs when the pituitary gland produces too much growth hormone after the growth plates have closed. The disorder affects 3 out of 50,000 people and ...
It’s composed of highly active chondrocytes and responsible for longitudinal bone growth. Consequently, the bone elongates at this growth plate until closure occurs at skeletal maturity. At the end of an individual’s growth period, the production of new cartilage in the epiphyseal plate stops.
Sever's disease, also known as calcaneus apophysitis, is an inflammation at the back of the heel (or calcaneus) growth plate in growing children. The condition is thought to be caused by repetitive stress at the heel. This condition is benign and common and usually resolves when the growth plate has closed or during periods of less activity.
