Which of the following is NOT a complication of a fracture?

1. Non-union

2. Pseudarthrosis

3. Bone marrow edema

4. Acute pain

The correct answer is: Acute pain

Acute pain is a common and expected symptom following a fracture. It is the body’s natural response to injury, signaling that there is damage to the tissues, and it serves an important purpose in alerting the individual to seek medical attention and avoid further harm. In contrast, non-union refers to a situation where a fractured bone fails to heal properly, which can complicate recovery. Pseudarthrosis occurs when a fracture heals in a way that creates a false joint, which also complicates healing and function. Bone marrow edema can indicate inflammation or injury in the bone but is generally regarded as a consequence of the fracture rather than a complication resulting from its healing process. Therefore, acute pain arises directly from the fracture itself and is part of the immediate injury response rather than a complication that arises later during the healing process.
