Wrist

The wrist contains eight small carpal bones divided into two rows. The proximal row of bones, comprised of the scaphoid, lunate and triquetrum, connects the radius and ulna to the metacarpals in the hand. The distal row of bones contains the trapezium, trapezoid, capitate, hamate and pisiform bones and is located closer to the fingers. The wrist is supported by two important ligaments called the collateral ligaments, which help to form a joint capsule around the eight carpal bones.wrist

The ulnar collateral ligament and the radial collateral ligament connect the forearm to the wrist and prevent the
wrist from bending too far in either direction, states eOrthodpod. Flexor and ex-tensor tendons connect muscle to bone and are responsible for helping to bend the wrist and curl the fingers and thumb. These tendons originate in the forearm. Three nerves that innervate the hand begin as a bundle in the shoulder and cross through the wrist. The radial, median and ulnar nerves carry motor signals to the muscles in the wrist and hand, and carry sensory signals back to the brain. Large blood vessels such as the radial and ulnar arteries travel alongside the nerves to supply the hand with blood.

How to Care Your Wrist 

Human wrist is more sensitive than other animal. we need to care always our body as well as Wrist also ,We are
doing a lot of job in our life ,and almost all job are doing to getting help from wrist . if somebody get fractured her wrist than he need to more care her wrist. The wrist is made up of eight small bones which connect with the two long forearm bones called the radius and ulna. Although a broken wrist can happen in any of these 10 bones, by far the most common bone to break is the radius. This is called a distal radius fracture by hand surgeons.

Some wrist fractures are stable. “Non-displaced” breaks, in which the bones do not move out of place initially, can be stable. Some “displaced” breaks also can be stable enough to treat in a cast or splint. Other fractures are unstable. In unstable fractures, even if the bones are put back into position and a cast is placed, the bone pieces tend to move or shift into a bad position before they solidly heal. This can make the wrist appear crooked.

Some fractures are more severe than others. Fractures that break apart the smooth joint surface or fractures that shatter into many pieces may make the bone unstable. These severe types of fractures often require surgery to restore and hold their alignment. An open fracture occurs when a fragment of bone breaks and is forced out through the skin. This can cause an increased risk of infection in the bone.

A wrist fracture occurs from an injury such as falling down onto an outstretched hand. Severe trauma such as car accidents, motorcycle accidents or falls from a ladder cause more severe injuries. Weak bones tend to break more easily.When the wrist is broken, there is pain and swelling. It can be hard to move or use the hand and wrist. Some people can still move or use the hand or wrist even if there is a broken bone. Swelling or a bone out of place can make the wrist appear deformed. There is often pain right around the break and with finger movement. Sometimes the fingers tingle or feel numb at the tips.

Treatment depends on many factors, including:

Type of fracture, whether it is displaced, unstable or open your Age, job, hobbies, activity level, and whether it is your “dominant” hand,Your overall general health,Presence of other injuries.
A padded splint might be worn at first in order to align the bones and support the wrist to provide some relief from the initial pain. If the fracture is not too unstable, a cast may be used to hold a fracture that has been set. Other fractures may benefit from surgery to put the broken bones back together and hold them in correct place.

Fractures may be fixed with many devices. Pins, screws, plates, rods or external fixation can all be used . A small camera might be used to help visualize the joint from the inside. Sometimes the bone is so severely crushed that there is a gap in the bone once it has been realigned. In these cases, a bone graft may be added to help the healing process. Your hand surgeon will discuss the options that are best for your healing and recovery.

During recovery, it is very important to keep your fingers moving to keep them from getting stiff. Your hand surgeon will have you start moving your wrist at the right time for your fracture. Hand therapy is often helpful to recover motion, strength and function. Recovery time varies and depends on a lot of factors. It is not unusual for recovery to take months. Even then, some patients may have stiffness or aching. Severe wrist fractures can result in arthritis in the joint. Occasionally, additional treatment or surgery is needed.
