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).
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.
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.
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 ...
SCFE is a Salter-Harris type 1 fracture (fracture through the physis or growth plate) through the proximal femoral physis, which can be distinguished from other Salter-Harris type 1 fractures by identifying prior epiphysiolysis, an intact (in chronic SCFE) or partially torn (in acute SCFE) periosteum, and the displacement being slower. Stress ...
The disorder has relatively mild signs and symptoms, including joint pain, scoliosis, and malformations of the hands, feet, and knees. [3] Some affected individuals are born with an inward- and downward-turning foot (a clubfoot). An abnormality of the kneecap called a double-layered patella is also relatively common.
Work with your doctor to create a personalized plan that includes calories, physical activity, and medications to help minimize symptoms and weight gain. 12. You're weighing yourself at different ...
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.
