Summary
Injuries to the hallux, sesamoid, and first metatarsal impact foot biomechanics and normal walking. These common foot injuries can lead to pain, swelling, and reduced motion.
Area of Science:
- Biomechanics
- Orthopedics
- Podiatry
Background:
- Hallux, sesamoid, and first metatarsal structures are crucial for foot biomechanics and propulsion during gait.
- Injuries to these structures are common and can significantly affect the functionality of the first ray and overall foot mechanics.
Purpose of the Study:
- To examine the biomechanical implications of hallux, sesamoid, and first metatarsal injuries.
- To understand how these injuries affect normal locomotion and lead to secondary complications.
Main Methods:
- Literature review of common foot injuries.
- Analysis of biomechanical principles related to the first ray.
- Case study review of patients with hallux, sesamoid, and first metatarsal injuries.
Main Results:
- Disruptions or injuries to the first ray can cause angular changes and arthritis.
- These alterations result in biomechanical issues such as pain, disability, compensatory movements, swelling, and decreased range of motion.
Conclusions:
- Injuries to the hallux, sesamoid, and first metatarsal have significant biomechanical consequences.
- Understanding these implications is vital for effective diagnosis and management of foot injuries to restore normal gait and function.

01:10Ankle Joint
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...
01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:10Bones of the Lower Limb: Tibia and Fibula
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...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
