กระดูกแตกร้าวหรือหัก fracture / broken bone
If more pressure is put on a bone then it can stand, it will split or break. A break or any size is called a fracture. If the bone punctures the skin it is called an open fracture (compound fracture).
A stress fracture is a hairline crack in the bone that develops because of repeated or prolonged forces against the bone. Considerations
It is hard to tell a dislocated bone from a broken bone. However, both are emergency situations, and the basic first aid steps are the same.
The following are common causes of broken bones;
.Fall from a height
.Motor vehicle accidents
.Direct blow
.Child abuse
.Repetitive forces, such as those caused by running, can cause stress fractures of the foot, ankle, tibia, or hip
Symptoms
.A visibly out-of-place or misshapen limb or joint
.Swelling, bruising, or bleeding
.Intense pain
.Numbness and tingling
.Broken skin with bone protruding
.Limited mobility or inability to move a limb
TREAT BLEEDING
.Place a dry, clean cloth over the wound to dress it.
.If the bleeding continues, apply direct pressure to the site of site of bleeding. DO NOT apply a tourniquet to the extremity to stop the bleeding unless it is life-threatening.
DO NOT
.DO NOT move the person unless the broken bone is stable.
.DO NOT move a person with an injured hip, pelvis, or upper leg unless it is absolutely necessary. If you must move the person, pull the person to safety by his clothes (such as by the shoulders of shirt, a belt, or pant-legs).
.DO NOT move a person who has possible spine injury.
.DO NOT attempt to straighten a bone or change its position unless blood circulation appears hampered.
.DO NOT try to reposition a suspected spine injury.
.DO NOT test a bone’s ability to move.
.Direct blow
