Which of the following is NOT classified as a traumatic or acute muscle injury?

1. Contusions

2. Bursitis

3. Muscle strains

4. Joint dislocation

The correct answer is: Bursitis

Bursitis is characterized as an inflammation of the bursa, which are small fluid-filled sacs that cushion the bones, tendons, and muscles near joints. This condition often arises due to repetitive motion or prolonged pressure, rather than as a direct result of a sudden injury or trauma. In contrast, contusions, muscle strains, and joint dislocations are classified as traumatic injuries because they usually result from a specific incident, such as a fall, a blow, or an overstretched muscle. These acute injuries are characterized by immediate pain, swelling, and possible loss of function in the affected area. Therefore, bursitis stands out from these other options as it does not originate from a singular traumatic event.
