What are carpal bones?
Karpal bones are eight short bones arranged in two rows of four, located in the wrist. The proximal line is the line closest to the arm, located next to the ulna and radius. The distal row is located next to metacarpals, which are the first row of bones in hand. In this context, the side of the furthest is from the body and the media is the side of the hand closest to the center of the body. The distal range of bones, which lies the farthest from the radius and the ulna, closest to the bones of the hand, from the media to the side, consists of hamat, capital, trapezes and trapezoids.
Carpal bones are short bones. The short bones have a compact bone surface surrounding the spongilla or porous bone center. The bone center contains small spaces that are usually filled with marrow.
As a group, eight carpal bones consists of a concave structure first of all, which means they have an internal curve and create an indentation or a shallow decline when viewed from the front. When viewed from behind, these bones form a convex structure, which is knownHe is bulging out. Flexor Retinaculum is a large, hard ligament that stretches through the carpal bones on the front. This liga is attached to a small protrusion on a trapezoid on the base of the thumb and is also connected to a small protruding structure of a similar hook on the hamate bones. The offset carpal bones, covered with flexor retinaculum, form a carpal tunnel.
Middle nerve, flexor tendons of fingers and blood vessels pass through the carpal tunnel, running from the forearm to hand. Carpal bones and flexor retinaculum have a very limited capacity to stretch. This means that if any inflammation, the battery of fluid, irritation or inappropriate tissue deposits occur in the carpal tunnel, medium nerve or one of the other structures in the tunnel is caught against bone or flexor retinaculum. This condition is known as the carpal tunnel syndrome.
Anatomical position of carpal bones is a joint, which allows flexibility and rotation of the hand and wrist. Four bone surfaces are surrounded by cartilage. It allowsIt allows joint or bones to articulate smoothly and move against each other without causing pain or discomfort. When this cartilage deteriorates, the bones grate against each other and can cause mild to severe pain.
The structure of carpal bones and the range of movement in the wrist means that this area is particularly susceptible to injury. Injuries can occur during sports activities as well as caused by falls and repeated movement. Most injuries occur when the wrist is in a bent position, such as carpal bones, tendons and bonds are the most stress under bending.
