Epifízisek

Epifízisek refers to the epiphyses, which are the expanded ends of long bones. These areas are primarily composed of spongy bone and are covered with articular cartilage, which allows for smooth movement at joints. The epiphyses are also the sites where longitudinal bone growth occurs, thanks to the epiphyseal plate, a layer of hyaline cartilage. Once skeletal maturity is reached, typically in late adolescence or early adulthood, the epiphyseal plates ossify and fuse with the diaphysis, the shaft of the bone, ceasing further longitudinal growth. This fusion is a key indicator of skeletal maturity. Fractures involving the epiphyseal plate, known as epiphyseal fractures or Salter-Harris fractures, can be particularly concerning as they can disrupt normal bone growth and lead to deformities if not properly managed. These fractures are more common in children and adolescents whose bones are still developing.
