The joint is a small plane synovial articulation between the fibular head and the tibia, and its job is to allow only tiny motions to accommodate leg and ankle movements. Because the fibula needs to shift a little as the foot moves and the knee or ankle twists, the proximal tibiofibular joint permits slight gliding with a bit of rotation, rather than locking in place or producing large movements. This limited mobility helps dissipate torsional stresses and is restrained by the joint capsule and ligaments, so movement is intentionally minimal. That’s why the correct description is slight movement.
