For a posterior fibular head dysfunction, which HVLA steps are correct?

• A. Patient is prone; plantar midfoot pressure to pronate the foot, then downward pressure on the fibular head followed by a thrust
• B. Patient is supine; dorsiflex the ankle and thrust anteriorly
• C. Patient is in a seated position and twists at the knee
• D. Patient is prone; apply upward thrust to the fibular head while dorsiflexing the foot

Answer: (A)

For a posterior fibular head dysfunction, the treatment aims to reposition the fibular head by using a setup that unlocks the distal fibula and then delivers a precise thrust to correct the head’s position. In this approach, having the patient prone provides good access to the fibular head. Plantar pressure on the midfoot to pronate the foot helps bring the distal fibula into a more favorable orientation, loosening the posteriorly stuck head from its tibial articulation. After applying downward pressure on the fibular head to preload the joint, a brief thrust is directed to realign the head in its proper position. This sequence matches the way the fibula moves within the ankle–knee complex and uses the correct vector to address a posterior orientation. Other methods described don’t produce the same effective vector and setup for correcting a posterior fibular head. A supine position with dorsiflexion and an anterior thrust targets a different orientation or dysfunction and isn’t the typical approach for a posterior head. A seated knee twist lacks the proper leverage and joint alignment needed. An upward thrust on the fibular head with dorsiflexion in the prone position also doesn’t provide the correct direction for this specific dysfunction.
