Fig 2.

This is a needle arthroscopic view of the left ankle. A thorough examination of the joint takes place including an examination of the instability of the syndesmosis. The fibula is seen on the left side of this image (lateral), the talus on the lower side (distal), and the tibia on the upper (proximal side). The syndesmotic instability is confirmed by applying intra-articular pressure with the probe into the syndesmosis, as well as performing a dynamic extra-articular external rotation stress test.
