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).
Sever's disease, also known as calcaneus apophysitis, is an inflammation at the back of the heel (or calcaneus) growth plate in growing children. The condition is thought to be caused by repetitive stress at the heel. This condition is benign and common and usually resolves when the growth plate has closed or during periods of less activity.
Temporary hemiepiphysiodesis is also known as guided growth surgery or growth modulation surgery. Temporary hemiepiphysiodesis is reversible i.e. the metal implants used to achieve epiphysiodesis can be removed after the desired correction is achieved and the growth plate can thus resume its normal growth and function. In contrast, permanent ...
The prognosis is good for stable lesions (stage I and II) in juveniles with open growth plates; treated conservatively—typically without surgery—50% of cases will heal. [68] Recovery in juveniles can be attributed to the bone's ability to repair damaged or dead bone tissue and cartilage in a process called bone remodeling.
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 ...

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. Consequently, the bone elongates at this growth plate until closure occurs at skeletal maturity.
Growth arrest lines, also known as Harris lines, are lines of increased bone density that represent the position of the growth plate at the time of insult to the organism and formed on long bones due to growth arrest. They are only visible by radiograph or in cross-section. The age at which the lines were formed can be estimated from a radiograph.
