Video 5-1. Anterior Talo Fibular Ligament Stressed via Drawer's Maneuver (Cadaveric Demonstration)
Video 5-2. Anterior Talo Fibular Ligament Cut and Then Stressed via Drawer's Maneuver
Video 5-3. Calcaneal Fibular Ligament Stressed with Inversion of the Subtalar Joint
Video 5-4. Calcaneal Fibular Ligament Cut and Then Stressed with Inversion of the Subtalar Joint
Video 5-5. Calcaneal Fibular and Anterior Talo Fibular Ligaments Intact and Stressed
Video 5-6. Calcaneal Fibular and Anterior Talo Fibular Ligaments Cut and Stressed Revealing Talar Tilt and Complete Dislocation of Ankle Joint
Video 5-7. Calcaneal Fibular Ligament, Normal
The maneuver is inversion of the subtalar joint.
Video 5-8. Calcaneal Fibular Ligament, Normal
The maneuver is inversion of the subtalar joint.
Video 5-9. Anterior Talo Fibular Ligament, Ruptured
The tear is distal and when the probe shifts to the right the tear will become apparent. An arrow flashes at the tear.
Video 5-10. Anterior Talo Fibular Ligament, Ankle Stressed with a Drawer's Maneuver
There is an ankle joint effusion with echogenic tissue within the joint.

Video 5-12. Peroneal Retinaculum Tear with Scarring of the Peroneus Brevis and Subtalar Joint Instability
This is a complicated video, please observe the following:
- The damaged peroneal retinaculum is communicating with the fibula via scar tissue. This is evidenced during the inversion stress.
- The peroneus brevis is adhered to the scar tissue, also observed during stress. Compare with other videos that visualize the calcaneal fibular ligament and see the longus does not separate from the brevis when stressed.
- The subtalar joint has (excessive) abnormal movement. Compare with other videos that have no subtalar instability. Also see cadaver videos of stressed CFL and see how well the joint articulation is maintained.
