Bone provides support, protection for organs, allows movement, and enables body growth.

Bones store minerals, maintain ion balance, and contribute to blood cell production in the marrow.

Dense bone found in the outer layer of bones, shaft of long bones, and joint surfaces. It provides strength and support.

Spongy bone found inside the body of long bones, vertebrae, and ends of bones. It provides strength and lightweight structure.

A complete or incomplete break in the continuity of a bone.

A fracture caused by a direct impact to the bone.

A fracture caused by force applied to a different part of the body, resulting in a break in another location.

A break in the bone that does not completely separate the bone into two pieces.

A break in the bone that completely separates the bone into two or more pieces.

The bone pieces move apart laterally.

Inspect the injured area for signs of swelling, deformity, bruising, or open wounds.

Palpate the injured area to check for tenderness, crepitus (a grating sound), and instability.

Do not move the injured limb unless distal to the injury. Assess the neurovascular status of the limb.

General treatment includes pain management (analgesia), fluid and blood replacement if needed, and antibiotics to prevent infection.

Local treatment includes reduction of the fracture (closed or open), immobilization (splint, traction, internal or external fixation), and exercises to promote healing and prevent complications.

A serious condition where increased pressure within a muscle compartment restricts blood flow, leading to tissue damage.

Death of bone tissue due to lack of blood supply, which can occur following a fracture, particularly at the neck of femur.

A break in the collarbone, often caused by direct or indirect trauma. The medial segment is displaced upward, and the lateral segment is displaced downward.

A break in the shaft of the humerus (upper arm bone), typically caused by direct trauma. Can lead to wrist drop due to radial nerve injury.

A fracture of the distal radius (forearm bone), commonly caused by falling on outstretched hand. The wrist appears deformed (dinner-fork deformity).
