Articulación del Tobillo
In this section, the speaker introduces the topic of ankle joint anatomy and mentions previous videos on related topics.
Ankle Joint Anatomy
- The anatomical name for the ankle joint is tibioastragalino, involving the tibia, fibula, and astragalus bones.
- Classified as a synovial joint, specifically a trochlear or hinge type allowing flexion and extension movements.
- Describes the articular surfaces of the tibia, fibula, and astragalus bones in detail.
Superficies Articulares y Ligamentos
This section covers the articular surfaces and ligaments of the ankle joint.
Articular Surfaces
- Details the specific parts of the tibia and fibula that articulate with the astragalus bone.
- Discusses the distal tibioperoneal joint separately from the main ankle joint.
Cápsula Articular y Ligamentos Externos
Focuses on the joint capsule and external ligaments maintaining stability in the ankle joint.
Joint Capsule and External Ligaments
- Explains how ligaments reinforce the joint capsule externally.
Articulación del Tobillo
In this section, the speaker discusses the ligaments of the ankle joint and their functions.
Ligaments of the Ankle Joint
- The peroneal superior and inferior are retinacula for muscles, not involved in joint function.
- Distal tibioperoneal joint includes anterior and posterior tibiofibular ligaments, separate from the ankle joint.
- The deltoid ligament is the main internal ligament, consisting of four portions studied separately.
- Portions include tibio-astragaline posterior and anterior, tibio-calcaneal, and tibial-scapoid.
Movimientos de la Articulación del Tobillo
This part covers movements of the ankle joint.
Ankle Joint Movements
- Ankle joint moves in flexion (dorsiflexion) and extension (plantarflexion) on a lateral-lateral axis.
- Dorsiflexion is standing on heels; plantarflexion is standing on tiptoes.
