What is a sliding joint?
The sliding joint, also called a flat joint or arthrodial joint, is a type of joint in which the joint surfaces of the participating bones are flat or only slightly curved. The joints are important structures in the body that combine bones and allow the movement and absorption of shocks. The ends of the bones that are joined in the joint are called articulating surfaces. The unique flat shape of the joint surfaces in the sliding joint let the bones slide over the other, often allows a large range of movement. These joints are present in the spine, wrist, legs and collarbones. The joints of the balls and sockets are shaped as their name would indicate and move rotary. The shape of the hinge joints allows them to move in one direction, as a hardware hinge. For the same reason, a flat rock is more easily traveling on a flat surface than an uneven rock over an uneven surface, the shape of the sliding clock is ideal for moving movements.
even with flat surfaces withHowever, the bones in the moving joints cannot move smoothly without lubrication. As a synovial joint, the joint joint uses synovial fluid and articular cartilage to miss and administration of bone movement. Synovial fluid has the consistency of egg whites and is excreted from a nearby bag called Synovial membrane. Another structure called Bursa also excludes a small amount of fluid to make the cartilage damp. The articular cartilage is a type of hyaline cartilage that surrounds the joint surfaces of the bones and protects them from friction and wear.
At the right work, the gliding joint should be able to achieve an optimal range of movement without causing pain. However, trauma, disease or disorder may cause pain or tenderness in the joint. Rheumatoid arthritis and osteoarthrosis are two of the most common culprits in joint pain. Rheumatoid arthritis is an autoimmune disorder or a disease in which the immune system attacks a healthy tissue that mainly focuses the joints in the hands and feet where the joints are moving. This aboutSickness is degenerative and incurable, although there are many treatment options. Osteoarthrosis is the result of joint wear for a long time and also does not have a medicine.
The chronic joint on the joint can also contribute to injuries or disorders such as bursitis, swelling of the burs. Bone fracture due to injury can disrupt cartilage, change bone orientation or put pressure on nerves. Treatment may include operations, orthosis and rest of the affected joint joint. Similarly, bone -shaped defects can also cause friction and grip of the nerves.
