What is the joint classification of the superior tibiofibular joint?

• A. plane
• B. slight movement
• C. fibrous
• D. synovial

Answer: (D)

This joint is a synovial joint. It is formed by the articulation between the fibular head and the lateral tibial condyle and is enclosed by a capsule that contains a synovial membrane and fluid, with articular cartilage on the contacting surfaces. The surfaces are relatively flat, which allows mainly a small gliding (plane-type) movement between the bones as the ankle moves. It’s held together by ligaments, notably the anterior and posterior superior tibiofibular ligaments, and the interosseous membrane contributes to stability, all of which are features of a true synovial joint. This distinguishes it from a fibrous joint, which would lack a synovial cavity, and explains why the inferior tibiofibular joint is not the correct comparison here.
