What does meniscoid entrapment typically involve during flexion?

• A. Meniscoid moves with the superior facet
• B. Meniscoid is trapped under the capsule
• C. Meniscoid moves with the inferior facet
• D. Meniscoid remains stationary

Answer: (C)

Meniscoid entrapment is a phenomenon that occurs in the facet joints of the spine, where small meniscoid structures can become caught during the movement of the joint, particularly during flexion. In the context of flexion, it is correct that the meniscoid moves with the inferior facet. During flexion, the inferior articular facet of the vertebra below moves upwards and forwards, while the superior facet of the vertebra above moves downwards and backwards. This coordinated movement allows for joint stability and motion; however, the meniscoid structure, which acts to absorb forces and reduce friction between the articular surfaces, will follow the inferior facet. This movement is important for maintaining the proper biomechanics of the joint; therefore, understanding meniscoid behavior helps in recognizing potential sources of pain and dysfunction in the spine, as entrapment can lead to restricted motion and discomfort.
