Information for Patients


Also called: Broken bone

A fracture is a break, usually in a bone. If the broken bone punctures the skin, it is called an open or compound fracture. Fractures commonly happen because of car accidents, falls or sports injuries. Other causes are low bone density and osteoporosis, which cause weakening of the bones. Overuse can cause stress fractures, which are very small cracks in the bone.

Symptoms of a fracture are

  • Out-of-place or misshapen limb or joint
  • Swelling, bruising or bleeding
  • Intense pain
  • Numbness and tingling
  • Limited mobility or inability to move a limb

You need to get medical care right away for any fracture. You may need to wear a cast or splint. Sometimes you need surgery to put in plates, pins or screws to keep the bone in place.

Jaw Injuries and Disorders

Your jaw is a set of bones that holds your teeth. It consists of two main parts. The upper part is the maxilla. It doesn't move. The moveable lower part is called the mandible. You move it when you talk or chew. The two halves of the mandible meet at your chin. The joint where the mandible meets your skull is the temporomandibular joint.

Jaw problems include

  • Fractures
  • Dislocations
  • Temporomandibular joint dysfunction
  • Osteonecrosis, which happens when your bones lose their blood supply
  • Cancers

Treatment of jaw problems depends on the cause.

  • Jaw - broken or dislocated
  • Malocclusion of teeth
  • Micrognathia
  • Prognathism
