FractureEn Español (Spanish Version)
A fracture is a break in a bone. It can involve any bone in the body.

Fractures may be:
Open—There is a break in the skin over the fracture.
Closed—The skin is not broken.
Fractures may also be described as:
- Chip (avulsion fracture)—A small piece of bone is broken away from the main bone.
- Compression—The bone is compressed together (ie, vertebrae).
- Comminuted—The bone is fragmented.
- Greenstick—This is a fracture in which one side of the bone is broken, and the other side is bent but not broken.
- Intra-articular—The joint is affected.
- Transverse—The bone is broken in a horizontal line that is perpendicular to the surface of the bone cortex.
- Oblique—The bone is broken in a line that is less than a 90° angle to the surface of the bone cortex.
- Spiral—The line of the fracture forms a spiral.
- Stress—A thin fracture line occurs due to overuse rather than a single traumatic incident.
Fractures are caused by trauma to the bone. Trauma includes:
The trauma is a physical force applied to the bone that the bone cannot withstand. Stronger bones can withstand more physical force than weaker bones.
A risk factor is something that increases your chance of getting a disease or condition. Risk factors for a fracture include:
Symptoms of a fracture include:
- Pain, often severe (primary symptom)
- Instability of the area around the break
- Inability to use the limb or affected area normally (there may be full or partial restriction in movement)
- Swelling or bruising caused by the bleeding from the bone and surrounding tissues
- Numbness caused by damage to a nearby nerve (rare)
- Fainting or even shock (rare–only in a severe trauma)
The doctor will ask about your symptoms and how you injured yourself, and examine the injured area.
Tests may include:
- Putting the pieces of bone together (may require anesthesia and/or surgery)
- Keeping the pieces together while the bone heals itself
Devices that can hold a bone in place while it heals include:
- A cast (may be used with or without surgery)
- Metal pins across the bone with a frame holding them outside the bone (requires surgery)
- A metal plate with screws (requires surgery)
- Screws alone (requires surgery)
- A rod down the middle of the bone (requires surgery)
Healing and Rehabilitation
Healing time ranges from three weeks for a simple finger fracture to many months for a complicated fracture of a long bone. All fractures require rehabilitation exercises to regain muscle strength and joint motion.
- Delayed union—It takes longer than usual to heal but does heal.
- Nonunion—The bone does not heal and needs some special treatment.
- Infection—This is more likely to happen after an open fracture or surgery.
- Nerve or artery damage—This usually occurs as result of a severe trauma.
- Compartment syndrome—Severe swelling in the spaces of the limbs that causes damage to body tissues.
- Late arthritis—This may happen if the surface of a joint is badly damaged.
You can reduce your chances of getting a fracture by:
- Not putting yourself at risk for an accident or other trauma to the bone
- Eating a diet rich in calcium and vitamin D
- Regularly doing weight-bearing exercise to build and maintain strong bones
- Regularly doing strengthening exercises to build strong muscles and prevent falls
- Patients with osteoporosis may benefit from bisphosphonate medications
