What is a scaphoid bone?

Scafoid bone, also called Navicular bone, is the largest bone in the proximal line of wrist, a highly flexible area between the forearm and the hands. The flexibility of the wrist can largely be attributed to its unique and complex composition, marked with two horizontal rows of small bones called cards. The scaphoid bone belongs to the proximal series of cards or the line closest to the body of the body and the farthest from the fingers. The proximal term is the comparative anatomical term, which refers to the point closest to the center line of the body, unlike the distal, which concerns the point of the farthest from the middle line. For example, when comparing the elbow and fingers, the elbow is proximal and the fingers are distal. The bones of the forearm, radius and ulna lie on the proximal side of the cards and the bone of the palm, the metacarpals spread down with distal towers. Finger bones, called phalanxes, articulate or associate, with metacarples. The scaphoid bone lies on the pallet side of the wrist and connects to the radius on the proximal side.

Because the lines are not perfectly straight, the scaphoid bones are articulated with the Lunate Carpal on the proximal side and on the middle side in the pinky direction. Scaphid bones are articulated with a trapezoid and trapezoid by carpal bone distal and chapter carpal bone on the proximal and media side. Looking at the right hand with the fingers towards the sky and the back of the hand towards the face are bottom, proximal series of cards, from left to right, scaphoid, lunate, triquetral and pisiform. The upper, proximal series of cards, from left to right, are trapezoids, trapezes, capitalization and hamina. Some students use the popular mnemonic "Some lovers try positions they can't handle" to remember cards and their positions from left to right and down.

Scafoid bone is the most commonly broken bone in the wrist and is difficult to recover due to limited circulation or blood flow. These breaks are usually the result of being a patiaNTA tries to break the fall with the palm outstretched. If there is a suspect of a break, patients should look for quick medical care, as incorrect healing can lead to complications such as avascular necrosis in which bones die of lack of blood supply. Symptoms of bone fracture may include pain and swelling in the wrist, especially near the base of the thumb. The doctor will feel the wrist to determine the source of the pain and then led the X -ray, the test used to take the bone image, to diagnose a break.

If a physician diagnoses a fracture, he will probably recommend a few weeks in the cast and plan a subsequent visits to the patient to check the Progress of the Healing via X -ray. If several months run and the fracture does not heal, it is considered to be a neion and may require an electric stimulator. The electric stimulator is worn as a bracelet and transmits electric currents to the wrist to help the healing process. If the injury is old or other treatment does not work, the doctor may recommend surgery nand scaphoid bones. This usually involves connecting the bone together with the bone graft, which inserts bone tissue from another part of the body into a fracture and a metal pin to secure the bone.
