Ankle Joint01:10

Ankle Joint

1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Bones of the Lower Limb: Tibia and Fibula

3.4K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Knee Joint01:23

Knee Joint

1.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Functional Classification of Joints01:09

Functional Classification of Joints

4.1K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Introduction to Joints00:58

Introduction to Joints

3.0K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Joints

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
The bones of a...

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Musculoskeletal System

Background:

  • The ankle is a frequent site of musculoskeletal injuries.
  • Understanding ankle anatomy and physiology is crucial for accurate diagnosis.
  • Common ankle conditions include lateral and medial sprains and Achilles tendinopathy.

Purpose of the Study:

  • To provide a framework for diagnosing and managing common ankle injuries.
  • To outline the role of history, physical examination, and diagnostic tools.
  • To detail treatment protocols for ankle sprains, tendinopathy, and fractures.

Main Methods:

  • Thorough patient history focusing on injury mechanism and symptom duration.
  • Specific diagnostic maneuvers to evaluate ankle structures and stability.
  • Application of the Ottawa Ankle Rules to determine the need for X-rays.

Main Results:

  • Ankle sprains and Achilles tendinopathy are prevalent in primary care.
  • Management involves protection, RICE protocol, NSAIDs, and activity modification.
  • Stable fractures are managed with orthoses; unstable fractures require orthopedic consultation.

Conclusions:

  • A systematic approach combining history, examination, and diagnostic rules aids in effective ankle injury management.
  • Conservative treatments are effective for common ankle sprains and tendinopathy.
  • Appropriate referral and immobilization are essential for ankle fractures.
