Mechanics of the toehold leglock
•••••••••••••••
A toe hold leglock involves torque force combining plantarflexion and inversion motion to the ankle which often results in ligament sprain. With sufficient force ligament rupture and ankle dislocation can occur.
.
This leg lock primarily attacks two joints simultaneously that make up the ankle.
1️⃣Talocrural joint
2️⃣Subtalar joint
There are two ligaments that primarily prevent this movement:
1️⃣anterior talofibular ligament 2️⃣calcaneofibular ligament.
These are the same ligaments that are damaged from a typical rolled ankle (ankle sprain). .
✳️Note: This breakdown covers typical toe holds. Some variations of the toe hold may instead involve tibial internal rotation at the knee and not ankle movement.
