City Of Villains Map Patch here. Epidemiology of Ankle Sprain. Origin: fibula Insertion: talus; Runs parallel to the foot in ankle dorsiflexion; Runs palallel to the leg in ankle.

ROM • Dorsiflexion = 20 degrees • Plantarflexion = 50 degrees • Anterior portion of the talar dome is @2.4mm wider than the posterior portion, making the ankle much more stable in dorsiflexion than in plantarflexion. Dungeon Siege 2 V2.3 Patch. Anterior Talofibular Ligament (ATFL) • Orign: anterior aspect of the distal fibula 1 cm from the tip of the lateral malleolus. • Insertion: lateral aspect of the talar neck just distal to the articular surface 18 mm proximal to the subtalar joint. • 7.2mm width, @12mm length (Ruth C, JBJS 1961;43A:229)• Strain increases when the ankle moves into greater degrees of plantar flexion, internal rotation, and inversion • Primary restraint to inversion in plantar flexion.

Also resists anterolateral translation of the talus in the mortise. Calcaneofibular Ligament (CFL) • Origin: distal tip of fibula adjacent to the ATFL, 8 mm proximal to the tip • Insertion: lateral wall of calcaneous, 13 mm distal to the subtalar joint, deep to the peroneal tendon sheaths. • 4-6mm in diameter (Ruth C, JBJS 1961;43A:229)• Angled 133 degrees (range, 113 to 150 degrees) in relation to the fibula with the ankle in plantigrade position. • Strain increases when the talus is dorsiflexed and inverted. • Primary restraint to inversion when the ankle is in neutral or dorsiflexion.

Limits talar tilt. Posterior Talofibular Ligament (PTFL) • Origin: posterior border of the fibula • Insertion: posterior lateral talus • 6mm diameter, 9mm length (Ruth C, JBJS 1961;43A:229) Lateral Talocalcaneal Ligament (LTCL) • Origin: lateral body of talus • Insertion: lateral calcaneous • variable size, often ill defined • Funtion: limits subtalar motion. Posteroinferior Tibiofibular Ligament. • Origin: • Insertion: • Funtion: Sural Nerve • sensory nerve formed by the medial sural nerve (branch of the tibial nerve) and lateral sural nerve(branch of the common peroneal nerve). • Courses between the heads of the gastrocnemius, eventually emerging though the gastrocs fascial covering.
