  1. Lesson 3 – Diagnosing Bone and Joint Injuries Chapter 1

  2. Common Skeletal System Injuries • Three common skeletal system injuries are fractures, dislocation and sprains. • Fracture – small break in a bone. • Dislocation – occurs when the end of a bone comes out of its joint. • Sprain – occurs when ligaments are stretched too ar and tear in places. Both sprains and fractures can cause swelling around the injured area.

  3. Identifying Injuries • Two ways to identify injuries of the skeletal system are X-rays and magnetic resonance imaging (MRI) • X-rays are a form of energy that travels in waves, like the light before your eyes can see it. • One limitation is that X-rays cannot be used to identify injury to ligaments and tissue. • MRI ‘s can take images of both the bones and soft tissues of the body.

  4. Treating Injuries • In addition to wearing a cast, two other ways to treat skeletal system injuries include surgical procedures such as joint replacement and arthroscopy. • Arthritis is a disease of the joints that makes movement painful. Doctors can replace knees, hips, fingers, shoulders, and wrists with joint replacement. • Joint injuries can also be treated by arthroscopic surgery. Doctors make a small incision and insert a slim, tube shaped instrument called an arthroscopic into the joint.
