Superior tibiofibular joint

The superior tibiofibular joint (Latin: articulatio tibiofibularis) is a plane type synovial joint of the lower leg. It is formed between the tibia and the fibula. This articulation is also called the proximal tibiofibular joint, and it is a limited movement joint.


Articulating structures of superior tibiofibular joint

The articular surfaces of the superior tibiofibular joint include the following:

  • Fibular articular surface of the lateral tibial condyle
  • Head of the fibula


Joint capsule and ligaments 

Both articular structures are surrounded by the fibrous joint capsule. Besides the capsule, this joint is strengthened with two ligaments - the anterior and posterior ligaments of the fibular head.
