BONE BREAK TREATMENT

• Keep the injured bone as still as possible; do not bear any weight on it

• Apply ice

• Keep the area of injury raised

BONE BREAK TREATMENT

• Seek medical care

• Treatment of the break depends on the area and severity of the injury

• The bone may be realigned and supported with a splint, case or brace

• Surgery may be needed

Healing

• Step 1: When a bone fractures, blood vessels are broken too. Blood pours from the vessels and forms a clot around the broken ends of the bone

• Step 2: New bone cells move into the blood clot. As more bone cells are made, the blood clot is gradually replaced by bone

• Step 3: Any old pieces of broken bone which jut out are absorbed into the blood stream, so the repair is smoothed down

BONE DISLOCATION

• When sudden pressure pulls a bone out of its socket at the joint

BONE FRACTURES

• Fractures of the bone are classified in two categories: the simple fracture and the compound fracture, in which the skin is pierced and the flesh and bone are exposed to infection.

SImple fracture

• Commonly occur from a high impact or trauma to the bone

• Defined by a crack in the bone

• Small cracks in the bone are called stress fractures- caused by overuse

Bone fracture

• The symptoms include:

• Out of place limb or joint

• Swelling, bruising or bleeding

• Numbness and tingling

• Limited mobility or inability to move a limb
