All of the following are characteristics of a simple (closed) fracture EXCEPT:

Explanation

## Understanding Simple vs Compound Fractures **Key Point:** A simple (closed) fracture is defined by the integrity of the overlying soft tissues and skin, NOT by the alignment or displacement of bone fragments. ### Characteristics of Simple Fractures | Feature | Simple Fracture | Compound Fracture | | --- | --- | --- | | Skin integrity | Intact | Broken/exposed | | Soft tissue damage | Minimal | Extensive | | Infection risk | Low | High (open to environment) | | Bone alignment | May be displaced or undisplaced | May be displaced or undisplaced | | Contamination | Closed system | Open to external pathogens | ### Why Each Option Is Correct or Incorrect **Options 1, 2, 3 (Correct):** - A simple fracture has intact skin and soft tissues, creating a closed system with minimal infection risk. - The fracture site is protected from the external environment. **Option 4 (INCORRECT — The Answer):** **Warning:** This is a common misconception. A simple fracture can be **displaced, angulated, or rotated** — the defining feature is NOT alignment but rather the integrity of the overlying tissues. A simple fracture may require significant reduction despite being "closed." **Clinical Pearl:** A patient with a simple but severely displaced femoral shaft fracture still has a simple fracture; the displacement does not convert it to a compound fracture unless the skin is breached. **High-Yield:** The classification (simple vs compound) is based on **soft tissue integrity**, not bone alignment. Alignment is a separate descriptor (undisplaced vs displaced).
