Anatomy & Physiology Musculoskeletal #18


Which pattern does the nurse document for the client who experiences a bone break where the fractured bone is both pushed and wedged into another bone fragment?


  1. Avulsion fracture
    • Rationale:

      An avulsion fracture is a type of fracture pattern. It is diagnosed when a fragment of the fractured bone is pulled off the bone at its tendon or ligament attachment.

  2. Depressed fracture
    • Rationale:

      A depressed fracture occurs when fragments of the fractured bone are pushed in beyond the surrounding skin. It often occurs with depressed skull fractures.

  3. Impacted fracture
    • Rationale:

      An impacted fracture occurs when the broken ends of the bone are jammed together. This often occurs due to the force of the injury.

  4. Compression fracture
    • Rationale:

      A compression fracture is typically caused by osteoporosis (i.e., a loss of bone mass) that occurs as part of aging. It is diagnosed when bones collapse and often occurs to the spinal vertebrae of those who are at risk for this type of fracture.


A fracture is defined as a broken bone.


Learning Outcomes

There are several different types and patterns for fractures. It is important for the nurse to be aware of these types and patterns for assessment and documentation purposes. An impacted fracture is one where the break in the bone causes it to be pushed and wedged against other bone fragments.

Test Taking Tip

Consider the definition of each fracture pattern to correctly answer this question.
