In that case more stem cells may happen into the hyaline cartilage growth plate line and differentiate to chondrocytes. My Son has bone age of 146 and just started arimidex to delay growth plate fusion.
These plates also known as epiphyseal plate or physis are the zones of cartilage.
How to delay growth plate fusion. The use of aromatase inhibitors has been shown to be effective in prolonging the length of the growth phase in children with idiopathic short stature constitutional growth delay delayed puberty as well as in children with growth hormone deficiency in which bone age advancement jeopardizes the results of hormonal replacement therapy with growth hormones. During childhood the growth plate matures and the total height of the growth plate decreases finally closing in late puberty with complete replacement of bone. The fusing growth plate was found to be entirely surrounded by a border of very dense cortical-like bone clearly isolating the growth plate from any vessels or osteoclasts Fig.
My Son has bone age of 146 and just started arimidex to delay growth plate fusion. How long can arimidex delay fusion. Estrogen may play a key role in epiphyseal fusion but may not halt growth plate cessation.
Low levels of estrogen may prevent growth plate fusion by preventing your bones from developing properly. In that case more stem cells may happen into the hyaline cartilage growth plate line and differentiate to chondrocytes. We postulated that the border of dense bone might function as a physical barrier for oxygen and nutrients to reach the fusing growth plate resulting in hypoxia and eventually cell death in a nonclassical apoptotic way through necrosis or a mixture of apoptosis and necrosisif this is the case than osteoclasts can help continue endochondral ossification by degrading this dense bone.
These plates also known as epiphyseal plate or physis are the zones of cartilage. There are at least two growth plates in each bone which determines the length and shape of the mature bone. The growth plates contribute new bones to the existing bones to grow.
Since these parts of the bones are soft they are prone to injury during the developmental. C Axial reformatted maximum intensity projection MR image obtained at the level of the growth plate is used with the following formula to estimate the percentage of the growth plate that is replaced by a bridge arrowheads. A b a g 100 where a b is the area of the bridge and a g is the area of the entire growth plate.
Treatment with an aromatase inhibitor anastrozole 1 mgday for 3 yr in a boy previously operated on for a hamartoma causing precocious puberty and presenting with advanced bone maturation and nearly fused epiphyseal cartilages slowed cartilage fusion consenting a higher final stature than expected 1644 cm vs 1584 cm. Understanding Growth Plate Fusionand growth plate senescence will help us understand if these processes can be reversed. And just as a note I am still working on devices and methodology to grow taller.
A Computed Microtomography Method for Understanding Epiphyseal Growth Plate Fusion. The epiphyseal growth plate is a developmental region responsible for linear. The usual progression of fusion of growth plates is elbow first then foot and ankle then hand and wrist then knee then hip and pelvis and last the shoulder and clavicle.
It is possible that he has finished however 14 would be quite early for a boy to stop growing unless he has gone through puberty early. In summary we found that RES delays growth plate fusion and thereby improves bone growth in female rabbits without having a systemic effect on the IGF-system. Based on our experimental data we believe that RES is a safe medication and might have a potential to be used clinically to promote growth in short children by delaying growth plate fusion.
First estrogen reversibly suppresses growth plate function including proliferation in the proliferative zone hypertrophic cell size and consequently the rate of longitudinal bone growth. Second estrogen irreversibly advances structural senescence of the growth plate and hastens epiphyseal fusion. Growth factors local regulators and hormones involved in growth plate maturation are described as well as four postulated hypotheses and theories regarding the final steps in epiphyseal fusion.
Apoptosis autophagy transdifferentiation and hypoxia. The conventional answer is that growth stops because of epiphyseal fusion an abrupt event in which growth plate cartilage is replaced by bone tissue. However careful but widely ignored observation suggests that growth ceases before fusion occurs 7 8 which indicates that fusion is the result not the cause of growth cessation 8 9.
Physis or growth plates are found in bones that undergo endochondral ossification. Radiographic features The physis appears as a radiolucent line in skeletally-immature patients located between the metaphysis and epiphy.
