Summary
Age is the primary factor linked to plantar fasciitis (PF), not leg length discrepancy (LLD). Unilateral PF pain commonly affects the shorter limb, indicating a potential biomechanical link.
Area of Science:
- Orthopedics
- Podiatry
- Biomechanical analysis
Background:
- Plantar fasciitis (PF) is a leading cause of heel pain, often unilateral.
- Risk factors include age, BMI, and physical activity, but unilateral prevalence is poorly understood.
Purpose of the Study:
- To investigate the association between plantar fasciitis (PF) and leg length discrepancy (LLD).
- To explore factors contributing to unilateral PF presentation.
Main Methods:
- A case-control study involving 120 participants (PF group vs. control group) matched for BMI and sex.
- Leg length discrepancy (LLD) was determined by scanometry, with >0.64 cm difference defined as significant.
- Multivariate logistic regression analysis was employed.
Main Results:
- Age was independently associated with PF (p < 0.001).
- No significant association was found between PF and leg length discrepancy (LLD).
- In unilateral PF cases, pain was more prevalent in the shorter limb (p < 0.05).
Conclusions:
- Age is the sole identified factor associated with PF diagnosis when controlling for sex and BMI.
- Leg length discrepancy (LLD) is not an independent risk factor for plantar fasciitis (PF).
- Unilateral PF predominantly affects the shorter limb, suggesting a localized biomechanical influence.

01:28Muscles of the Leg that Move the Foot and Toes
1.5K
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....

01:10Bones of the Lower Limb: Tibia and Fibula
3.3K
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...

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:10Ankle 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...

01:16Bones of the Lower Limb: Femur and Patella
2.5K
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...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...
