Ankle and foot

Calf squeeze test

Compressietest syndesmose

What you examine
Injury of the syndesmosis and of the interosseous membrane above it.
Procedure
Squeeze the tibia and fibula together with both hands halfway up the lower leg, well above the ankle.
Positive when
Pain distally at the ankle, so far from the site where the pressure is applied.
What the test is worth
Specificity around 0.88, sensitivity low (around 0.30). Useful to rule in, not to rule out.
Caution
Pain at the site of the squeeze itself does not count: that may be a calf muscle injury or a stress fracture. Only pain referred to the ankle is positive.
Joint
Distal tibiofibular syndesmosis (syndesmosis tibiofibularis)
Body region
