Ankle and Foot Joints - Talocrural, Subtalar, Tarsal and Toe Ligaments and Injuries

Explore the comprehensive anatomy of ankle and foot joints through this 13-minute educational video that systematically examines each major articulation from the ankle down to the toes. Begin with the talocrural (ankle) joint, learning about its medial and lateral malleolar facets, joint capsule, deltoid ligament complex, and lateral collateral ligaments that resist eversion and inversion respectively. Progress through the subtalar joint and its four key ligaments (lateral, posterior, interosseous, and medial talocalcaneal), then examine the talocalcaneonavicular complex including the crucial spring ligament. Study the calcaneocuboid joint with its bifurcate, dorsal, plantar, and long plantar ligaments, followed by the functional transverse tarsal joint that enables forefoot rotation. Investigate the smaller but important cuneonavicular and cuneocuboid joints with their dorsal, plantar, and interosseous ligament systems, plus the intercuneiform joints that maintain cuneiform bone integrity. Analyze the critical tarsometatarsal joints (Lisfranc complex) and intermetatarsal joints that provide midfoot stability through their extensive ligament networks. Examine the metatarsophalangeal joints with their collateral and plantar ligaments plus deep transverse metatarsal ligament, and conclude with interphalangeal joint anatomy. Learn about the foot's three arch systems - medial longitudinal, lateral longitudinal, and transverse - understanding their support mechanisms through ligaments and muscles like the tibialis posterior and fibularis longus. Discover common pathological conditions including pes planus (flatfoot) with its collapsed medial arch causing strain and gait changes, and pes cavus (high arches) leading to reduced shock absorption and instability. Gain insights into Lisfranc injuries and their impact on midfoot stability, with clinical correlations supported by authoritative anatomical references and enhanced by visual demonstrations using Complete Anatomy software.
