Wachstumsplatten

Wachstumsplatten, also known as growth plates or epiphyseal plates, are areas of hyaline cartilage found in the long bones of children and adolescents. These plates are responsible for longitudinal bone growth. They are located near the ends of long bones, specifically at the metaphysis, which is the area between the epiphysis (the rounded end of the bone) and the diaphysis (the shaft of the bone). Within the growth plate, chondrocytes (cartilage cells) proliferate, mature, and eventually calcify, forming new bone tissue. This process allows bones to lengthen.

The growth of the epiphyseal plate is regulated by hormones, including growth hormone and sex hormones. As an individual reaches skeletal maturity, typically in late adolescence or early adulthood, the growth plates undergo ossification, meaning the cartilage is replaced by bone. Once ossified, longitudinal bone growth ceases. Injuries to growth plates can be serious, potentially leading to deformities or premature cessation of growth in the affected bone. Doctors often use imaging techniques like X-rays to assess the status of growth plates, particularly when evaluating skeletal development or potential growth disturbances. The presence and condition of growth plates are crucial indicators of skeletal maturity and potential for future height.
