This plate is the region where the endochondral ossification process continues through the growth period of an individual, leading to the lengthwise growth of the long bone. The growth plate, or also known as epiphyseal plate or physis, is the area of growing tissue near the ends of our long bones. Limb development is initiated during the fourth week of gestation and results in the formation of the limb bud. Digestive System 95 Terms. The structure indicated is the epiphyseal line.. Blood supply decreases from the reserve zone to the zone of degeneration. Lengthening can accomplished by bone graft or distraction osteogenesis. The process starts with recruitment of chondrocytes in the stem cell zone, then actively proliferates by cell division and followed by differentiation, apoptosis and finally mineralization in the hypertrophic zone. The epiphyseal plate, also known as a growth plate, is an area of cartilage found on the long bones which enables the bone to continue growing with the child. These cell clusters differentiate into chondrocytes, which proliferate to form the growth plate or physis. ScienceDirect ® is a registered trademark of Elsevier B.V.

Ryan, in, Encyclopedia of Endocrine Diseases (Second Edition), Thyroid Hormone in Bone and Joint Disorders, J.H. Excess GH levels in pre-pubertal children where the epiphyses are yet to fuse results in uncontrolled linear growth, termed as gigantism. ANDREW WAINWRIGHT BSc (HONS), MB, ChB, FRSC (Tr AND Orth), TIM THEOLOGIS MD, MSc, PhD, FRCS, in Evidence-Based Orthopaedics, 2009, The growth plate of the distal radius is the most frequently injured, usually with a SH type I or II pattern. Metaphyseal Artery: Supplies the secondary and primary spongiosa with a rich blood supply.Fig. Among other hormones, GH and IGF-1 regulates this process. Failure to recognize a growth plate arrest can quickly lead to deformity (Figs. The surgeon must weigh the risk/benefit ratio between intra-articular osteotomy and acceptance of the malunion. What is the Epiphyseal Plate? The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place. These plates permit growth after birth, allowing the long bones of the body to extend … The formed cartilage is then calcified, degraded, and replaced by osseous tissue. Epiphyseal closure or the stoppage of bone growth occurs between the ages of eighteen and twenty-five. … 1 decade ago. The Epiphyseal Plate keeps generating new cartilage during time of life when growing. • The Epiphyseal line is formed after the epiphyseal plate has stopped producing bone). Scott H. Kozin MD, in Principles and Practice of Wrist Surgery, 2010. Epiphyseal plates, or growth plates that bookend bones, are found in children and adolescents; after reaching adult maturation, the epiphyseal plates reach their growth limit and become epiphyseal lines. On the diaphyseal side, cartilage is ossified, and the diaphysis grows in length. 15. Intra-articular malunion can occur after a Salter-Harris III or IV fracture. If the patient is close to skeletal maturity, little remodeling can be expected. At this site, cartilage is formed by the proliferation and hypertrophy of cells and synthesis of the typical extracellular matrix. Early work indicated that Ihh induces expression of PTHrP in the perichondrium36 and that PTHrP signaling then stimulates cell proliferation via its receptor expressed in the periarticular chondrocytes.37 FGF-18 signaling via FGFR3 can inhibit Ihh expression30 and BMP signaling up-regulates the expression of Ihh in cells that are beyond the range of the PTHrP-induced signal.26 Recent evidence indicates that Ihh acts independently of PTHrP on periarticular chondrocytes to stimulate differentiation of columnar chondrocytes in the proliferative zone, whereas PTHrP acts by preventing premature differentiation into prehypertrophic and hypertrophic chondrocytes (thereby suppressing premature expression of Ihh).38 Thus, Ihh and PTHrP by transiently inducing proliferation markers and repressing differentiation markers function in a temporo-spatial manner to determine the number of cells that remain in the chondrogenic lineage versus those that enter the endochondral ossification pathway. J Bone Joint Surg [Am] 45:587, 1963.)Fig. Growth plate closure occurs in 4% to 5% of all Salter-Harris distal radius fractures.20,21 All growth plate fractures require a radiograph 3 to 6 months after healing to ensure continued growth. The proximal plate is affixed to the radius using a bone reduction clamp. The epiphyseal plate is composed of cartilage. The physics of the proximal humerus. This area is also known as the growth plate or epiphyseal disk. Growth in children: The epiphyseal plates are the cartilage growth areas near joints where bones grow in length.
