While bones may increase in width through an increase in length, bones that increase in length do so, and a band of cartilage known as the epiphyseal Plate between the bone and the epiphysis and diathesis forms the epiphysis plate. Is. Additional cartilage may be placed on that diathesis side of the diathesis.
Then converted to bone, an epiphyseal plate in the region of resting cartilage has four recognized regions. Adjacent to the bone in the epiphysis, another region anchors the epiphyseal plate to the surface of this bone, the region of proliferation Cartilage chondrocytes divide rapidly. A series of chondrocytes are present in increasingly long piles; these stacks will replace the cartilage, which calcifies and dies where the epiphyseal plate meets diathesis in the third region of hypertrophic.
Cartilage with chondrocytes which further produce glycogen, does.
The cavities are the spaces they occupy, and the lacunae contract, and the large matrix between the cartilages reach the diaphragm. That is a problem for chondrocytes because cartilage is avascular, and these chondrocytes rely on their gas exchange and diffusion through the matrix to obtain their nutrients. Cartilage silencing these chondrocytes will eventually be reabsorbed by osteoclasts as osteoblasts and capillaries invade the area to replace this dying cartilage with bone. It occurs in the area of calcified cartilage, and it occurs in the epiphyseal plate.
That bones can link the length of the cleavage until after birth. If the epiphyseal plate survives, the bone will continue to elongate during puberty. Hormones cause the bone to grow faster. Once it crosses the hyaline cartilage of the epiphysis plate, bone in the epiphysis and bone in the diathesis form an epiphysis, the line will fuse, and the bone has then reached its adult length.
Epiphyseal Plate Fracture and repair.
There are different types of appendiceal plate fractures. In a type 1 growth plate, there is a breakthrough in the bone that separates the ends of the bone from the shaft of the bone and completely disrupts the growth plate. Type 2 This is an extension of type 1 and is a breakthrough bone over the growth plate. However, with type 2, the crack also passes through the shaft of the bone.
And the most common type of growth plate fracture, type 3, is the fracture that passes through a portion of the growth plate. Eventually, a piece of bone breaks off, and this is more common in older children. Type 4 is a breakthrough in the bone shaft, and type 5 is an injury that crushes the growth plate by compressive force to the growth plate. And bone ends are very rare in the US who are susceptible to this fracture.
Because the growth plate is the most vulnerable point of injuries to a child’s growing skeleton. The cause of bone fractures in the US is simply because a child’s bone is stronger than an adult’s. Huts are more vulnerable, and growth plate injuries account for one-third of all childhood fractures. And growth plate injuries are twice as likely to occur in boys and girls. And one reason for this is that girls’ bodies mature earlier than boys’ bodies, so their growth plates are replaced by stronger bones earlier than boys.
How do you get a growth plate fracture? Growth plate fractures often occur, as in item four. Most common in the body’s long bones, such as the sesamoid or flat bones, are the femur, the tibia, and the fibula radius. Sometimes the ankle or foot bones and phalanges and most growth plate injuries and children commonly suffer falls while running or playing competitive sports such as football. There are. Basketball, baseball, softball track in gymnastics, and even in competitive sports such as gymnastics or baseball, too many repetitive movements can cause foot injuries to develop, often only on the bones.
Going fast and then doing recreational activities like biking, sledding, skiing, skateboarding, and rollerblading is ok. Now you know how you get this fracture? How do you first recognize it? It will be a constant pain after a few days. The pain subsides, and it can get worse. Therefore, it is important to take into account the possibility of an official plate fracture.
If the skeletally immature patient presents with these symptoms, there may be a discreet gait. , it is lame, and this occurs if the injury is to the lower limb. It may be possible that the difference in limb length and the presence of a visible deformity may have long-term consequences chronic at the fracture site after healing. Pain is osteoarthritis. My arthritis is not uncommon later in life. As fractures usually occur along joint lines and can affect the structural integrity of the cartilage, over-stimulation of healing by the limb may result in uneven limb, osteoblastic recruitment the fracture site could.
Activity will increase. Essentially when it is at the health site, the injured limb is longer than the uninjured limb. If there is a knee fracture, it is not uncommon for the patient to have follow-up visits until the skeleton is immature. But if it is elsewhere and it is standard for the patient to have a follow-up visit up to a year later.
The injury, as mentioned in the last slide, could be uneven limbs. You can see if the child’s knee is broken. I think it will heal as if it were a fracture. A site on the other side of the fractured bone and most formally formed by a growth plate will now be filled with a bony bridge GE.
If this occurs on one side of the bone, you will have a closed growth plate and limited growth on that side, while the other side will continue to grow longer and mature. That can lead to abnormalities in bone length and overall organ structure, resulting in good intervention strategies and non-surgical in some of the situations outlined in the previous slide.
On the other hand, if this fracture is treated properly, many people can recover well without surgery simply by applying a stable cast. And sometimes limiting participation in physical activity. If this fracture is unstable, then surgical intervention is required. The image on the right shows the reduction in internal fixation surgery, which is the most commonly used surgery to repair these fractures; as you can see, the bone fragments are reduced or as if moved back into place Gone and fixed by screws, hence the name it is not uncommon for surgeons to perform well after this surgery.
How does the reaction proceeds that will differentiate into bone and cartilage-producing cells? A cartilaginous soft callus is formed by counterblast. Eventually, the cartilaginous callus will be removed by osteocytes and then replaced by bone through osteoblastic activity. I mentioned earlier that osteoblasts would harden and lay a bony matrix around the fracture throughout the patient’s life. Eventually, all weakened spongy bone will be replaced by a healthy and new bone due to the compression of the bone. It can be displayed in the image.
