The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
Epiphysiodesis is a pediatric orthopedic surgery procedure that aims at altering or stopping the bone growth naturally occurring through the growth plate also known as the physeal plate. There are two types of epiphysiodesis: temporary hemiepiphysiodesis and permanent epiphysiodesis.
Multiple epiphyseal dysplasia (MED), also known as Fairbank's disease, is a rare genetic disorder (dominant form: 1 in 10,000 births) that affects the growing ends of bones. Long bones normally elongate by expansion of cartilage in the growth plate (epiphyseal plate) near their ends.
The cartilage cap is less than 2 cm thick and the thickness decreases with age. A cap more than 2 cm thick, indicates malignant transformation of a tumor. The cartilage cap merges with the epiphyseal area of the long bones called spongiosa. In the spongiosa, the chondrocytes are arranged in accordance with the epiphyseal growth plate. The ...
The metaphysis may be divided anatomically into three components based on tissue content: a cartilaginous component (epiphyseal plate), a bony component (metaphysis) and a fibrous component surrounding the periphery of the plate. The growth plate synchronizes chondrogenesis with osteogenesis or interstitial cartilage growth with both ...
Articular cartilage: This layer coats the bone ends, concerned with joint movement. Epiphyseal growth plate: This transverse layer lies between the epiphysis and diaphysis. It’s composed of highly active chondrocytes and responsible for longitudinal bone growth.
Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex). Pressure epiphyses assist in transmitting the weight of the human body and are the regions of the bone that are under pressure during movement or locomotion.
Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.
