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).
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.
Distal to the forearm bones are the metacarpal bones, which reside in the forelimb. These bones are located just beyond the wrist and serve as a link to the phalanges, or finger bones, at the end of the limbs. In the lower body, the femur is a prominent bone positioned between the hip and knee.
Most growth plate fractures heal without any lasting effects. [1] Rarely, bridging bone may form across the fracture, causing stunted growth and/or curving. [1] In such cases, the bridging bone may need to be surgically removed. [1] A growth plate fracture may also stimulate growth, causing a longer bone than the corresponding bone on the other ...
It has been shown in the past that attempts to correct the slippage by moving the head back into its correct position can cause the bone to die. Therefore the head of the femur is usually pinned 'as is'. A small incision is made in the outer side of the upper thigh and metal pins are placed through the femoral neck and into the head of the femur.
The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland .
Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the distal end of the bone. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body). The end of the long bone opposite to the head is known as the base.
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.
