Anatomy of the Fibula

In this video, Juan José Sánchez discusses the anatomy of the fibula, one of the leg bones. He explains the divisions of the lower limb and focuses on the structure and functions of the fibula.

Divisions of Lower Limb

• Juan José Sánchez introduces the four portions of the lower limb: pelvic girdle, thigh (femoral portion), leg (tibia and fibula), and foot.

Anatomy of Fibula

• The fibula is one of two long bones in the leg, along with the tibia. It supports movement rather than body weight.

• The fibula consists of three portions: two epiphyses (proximal and distal) and a diaphysis.

Superior Epiphysis

• The superior epiphysis includes the head and neck of the fibula, articulating with tibia and talus bones.

Styloid Process and Edges

• The styloid process is a notable feature on the posterolateral region.

• Three edges - anterior, interosseous, posterior - define faces on the fibula.

Faces of Fibula

Fibula Osteology Overview

In this section, the speaker discusses the anatomy of the fibula, focusing on specific features such as the internal ridge, malleoli, and articulation points.

Internal Ridge of Fibula

• The internal ridge is located between the internal edge and posterior edge of the fibula.

• It is specifically found on the posterior face of the fibula.

• The internal ridge serves as a distinguishing feature on the fibular bone.

Distal Fibular Anatomy

• The distal part of the fibula articulates with both tibia and talus bones.

• At this level, we find the talofibular joint and tibiofibular joint.

• The lateral malleolus is a large extension at the inferior epiphysis of the fibula.

Detailed Features of Lateral Malleolus

This part delves into the intricate details regarding the lateral malleolus's structure and its articulation points.

Articulation Points

• The lateral malleolus has an articular facet that articulates with the talus bone.

• A fossa known as malleolar fossa is present in the posterior part of the lateral malleolus.

Structural Components

• The lateral malleolus extends laterally from the fibula's inferior epiphysis.

• It houses an articular facet for connecting with the talus bone.

Closure and Call to Action

Concluding remarks by summarizing key points discussed about fibular anatomy and encouraging viewer engagement.

Recap and Engagement

• The articular facet on lateral malleolus connects with talus bone for joint movement.

• Posteriorly, there exists a depression called malleolar fossa for additional structural context.
