Document Summary
Lecture 3: the four miq & ho(cid:449) to. Responsible for limiting anterior translation of the talus: cf: calcaneofibular: limits inversion, particularly during dorsiflexion. Isn"t attached to the talus, therefore doesn"t limit its translation (note: Talo isn"t in the name: ptf: posterior talo-fibular: limits inversion, particularly during dorsiflexion. Is responsible for limiting posterior translation of the talus. If you have an anterior structure: during plantarflexion, talus translates/slides anteriorly, out of the mortise, during dorsiflexion, talus translates/slides posteriorly, into the mortise. Deltoid ligament complex (medial side): thicker and wider, more reinforcement on medial side generally (supports more weight, shared job: limit eversion, names of 4 ligaments, anterior tibiotalar ligament(att): limits plantar flexion. Limits anterior translation of the talus: tibionavicular (tn): almost parallel to att: plantarflexion, posterior tibiotalar ligament (ptt): anterior tibiotalar ligament: limits dorsiflexion. Limits posterior translation of the talus: tibiocalcaneal (tc): limits neither plantar, neither dorsi. Big picture: foot architecture: 2 longitudinal arches: 1 lateral and 1 medial, 1 transverse arch.
