Bones of the Lower Limb: Tibia and Fibula

Bones 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...

Muscles of the Leg that Move the Foot and Toes

Muscles 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.

Diabetic Foot Ulcer

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...

Area of Science:

Biomechanics
Orthopedics
Human Motion Analysis

Background:

The foot is a complex structure with multiple functional units.
Understanding foot kinematics is vital for diagnosing and treating conditions like rheumatoid arthritis.
Existing models may not fully capture the intricate movements of the foot, particularly the midfoot.

Purpose of the Study:

To introduce and validate the Ghent Foot Model, a multi-segmented foot model for clinical application.
To describe the kinematic patterns of the foot's functional units during gait.
To assess the repeatability and consistency of the model's measurements.

Main Methods:

A 6-camera motion capture system (500 Hz) recorded surface marker data.
Ten healthy subjects walked barefoot on a 12m walkway at self-selected speeds.
Plantar pressure measurements synchronized with motion capture to define foot rollover phases.

Main Results:

The Ghent Foot Model includes segments: lower leg, rearfoot, midfoot, lateral forefoot, medial forefoot, and hallux.
Joint angles in sagittal, frontal, and transverse planes were calculated for each segment.
Low intra-subject variability (0.7°-5.8° ROM) demonstrated high repeatability.

Conclusions:

The Ghent Foot Model provides reliable in vivo intersegment motion measurement of the foot.
The model's repeatable kinematic patterns align with biomechanical and clinical knowledge.
This tool is valuable for clinical assessment and research in foot biomechanics and pathology.
