Bones of the Lower Limb: Tibia and Fibula01:10

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...

Muscles 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....

Bones 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...

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...

Area of Science:

  • Biomechanics
  • Human Gait Analysis
  • Musculoskeletal Ultrasound

Background:

  • Human gait involves functional rockers and tendon behavior in the stretch-shortening cycle.
  • The relationship between tendon morphology and rocker duration in gait has not been previously studied.

Purpose of the Study:

  • To investigate the association between patellar tendon, Achilles tendon, and plantar fascia morphology and the duration of functional rockers during human walking.

Main Methods:

  • Thirty-nine healthy men underwent ultrasound to measure tendon and fascia morphology.
  • Gait data, including rocker duration, were collected using a baropodometric platform.
  • Statistical analysis (t-test) compared soft tissue morphology with rocker duration.

Main Results:

  • A longer duration of rocker 1 was observed in individuals with thicker patellar tendons.
  • Thicker Achilles tendons were also associated with a longer rocker 1 duration.
  • No significant differences in rocker duration were found concerning Achilles tendon or plantar fascia morphology.

Conclusions:

  • Increased patellar tendon thickness is significantly associated with extended rocker 1 duration during walking in healthy adults.
  • This finding highlights a potential link between tendon properties and gait dynamics.
