What type of injury results in tenderness of the muscles adjacent to the spine?

• A. Sacroilliac joint injury
• B. Myalgia
• C. Paraspinal tenderness
• D. Ecchymosis

Answer: (C)

Tenderness of the muscles adjacent to the spine is specifically referred to as paraspinal tenderness, which directly relates to inflammation or strain in the muscles that run parallel to the spinal column. This condition can arise due to various factors, including muscle strain, overuse, or injury, which often leads to discomfort or pain in the surrounding areas.

Understanding paraspinal tenderness involves recognizing the anatomy and function of the paraspinal muscles, which are vital for supporting the spine, facilitating movement, and maintaining posture.

Other options reflect different conditions: sacroiliac joint injury primarily affects the joint between the sacrum and ilium, resulting in pain in the lower back or buttocks; myalgia refers to general muscle pain without specifying location, and ecchymosis refers to bruising caused by blood escaping into the tissues, not directly associated with muscle tenderness.
