Metaphysis. The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including mesenchymal ...
Anatomical terminology. [edit on Wikidata] The diaphysis (pl.: diaphyses) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
Metaphyseal dysplasia. Metaphyseal dysplasia, or Pyle disease, [3] is a disorder of the bones. It is a rare disease in which the outer part of the shafts of long bones is thinner than normal and there is an increased chance of fractures. Its hallmark feature is an abnormality of the long bones in the arms and legs in which the ends (metaphyses ...
A Jones fracture is a broken bone in a specific part of the fifth metatarsal of the foot between the base and middle part [ 8 ] that is known for its high rate of delayed healing or nonunion. [ 4 ] It results in pain near the midportion of the foot on the outside. [ 2 ] There may also be bruising and difficulty walking. [ 3 ]
The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body.
A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell -rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [2] Typically, there are no symptoms unless there is a fracture. [2] It can occur as part of a syndrome such as when multiple non-ossifying fibromas occur in ...
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1][2] It can manifest in localized or generalized osteosclerosis.
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).
