Epifyysialue

Epifyysialue, also known as the growth plate or physis, is a hyaline cartilage area located near the ends of long bones in children and adolescents. It plays a critical role in the longitudinal growth of bones, allowing for increase in height during developmental years. The epifyssial plate is situated between the metaphysis (the neck portion of the bone) and the epiphysis (the rounded end part of the bone).

This cartilage zone is organized into distinct layers, including the resting zone, proliferative zone, hypertrophic zone, and calcification zone. Chondrocytes (cartilage cells) within these layers undergo a process of proliferation, maturation, and ossification, which leads to the lengthening of the bone. Over time, as an individual matures, the epiphyseal plates gradually ossify and become epiphyseal lines in adulthood, marking the end of bone growth.

The epifyysialeue is essential for normal skeletal development, and any disruptions or injuries to this zone can result in growth disturbances, such as limb length discrepancies or deformities. Common injuries involve fractures through the growth plate, which are classified by the Salter-Harris system based on the injury pattern.

Understanding the epifyysialue is important in pediatric medicine, orthopedics, and radiology, as its appearance and integrity can indicate normal growth or underlying pathologies. Monitoring the development and closure of growth plates can help diagnose growth disorders and plan appropriate interventions during childhood and adolescence.
