During the syndesmosis squeeze test, where are the tibia and fibula compressed?

• A. Tibia and fibula are compressed together at mid calf while ankle pain response is assessed
• B. Tibia and fibula are compressed at the ankle joint
• C. Heel is tapped while the knee is flexed
• D. The foot is inverted while compressing the tibia and fibula

Answer: (A)

The test targets the syndesmotic ligaments between the tibia and fibula, which are stressed when the two bones are squeezed together above the ankle. By compressing the tibia and fibula at the mid-calf, you push the bones toward each other in a way that transmits force through the distal tibiofibular joint. If the syndesmosis is injured, this maneuver reproduces pain or a feeling of instability at the ankle, indicating a high ankle sprain. Compressing at the ankle joint itself wouldn’t specifically stress the syndesmosis, and other maneuvers like tapping the heel or inverting the foot test different structures. So, the correct location is the mid-calf region where the tibia and fibula are compressed together.
