Which structure is primarily responsible for producing sharp pain with movement in facet dysfunction?

• A. Articular cartilage
• B. Joint capsule
• C. Intervertebral disc
• D. Ligaments

Answer: (B)

In the context of facet joint dysfunction, the joint capsule plays a crucial role in the experience of sharp pain with movement. The joint capsule surrounds the facet joints, which are synovial joints located between the vertebrae in the spine. When these joints are subjected to injury, degeneration, or inflammatory processes, the joint capsule can become wider or more sensitive, leading to increased pain with certain movements, particularly those that engage the facet joints. When movement occurs, the joint capsule is put under tension, and if it is inflamed or injured, it can produce sharp pain signals that are perceived by the nervous system. This pain can be exacerbated by activities that involve extension or rotation of the spine, which places additional stress on the facet joints and the surrounding structures, including the joint capsule. Understanding the role of the joint capsule in facet dysfunction is vital for recognizing the mechanics of back pain and guiding appropriate evaluation and treatment strategies.
