Ankle Joint01:10

Ankle Joint

2.2K
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...

Pulse Assessment Sites01:11

Pulse Assessment Sites

1.8K
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...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

6.8K
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 Toes01:28

Muscles of the Leg that Move the Foot and Toes

3.1K
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....

Knee Joint01:23

Knee Joint

2.6K
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...

Circular Shafts - Elastoplastic Materials01:24

Circular Shafts - Elastoplastic Materials

256
The study of solid circular shafts under stress shows that within the elastic limit, stress increases directly to the distance from the shaft's center. This relationship holds until the shaft reaches a critical point of stress, beyond which it begins to yield, marking the transition from elastic to plastic deformation. At this crucial juncture, the maximum torque the shaft can endure without permanent deformation is determined, signifying the limit of its elastic behavior.
As torque on the...

Summary

Sonoelastography may help assess soft tissue stiffness in congenital clubfeet, finding the Achilles tendon stiffer in affected feet. Further research is needed to confirm its utility in evaluating clubfoot treatments.

Area of Science:

  • Orthopedics
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Congenital idiopathic clubfoot is characterized by increased soft tissue stiffness.
  • Sonoelastography is an emerging imaging technique for assessing tissue stiffness.
  • Its application in clubfoot evaluation requires further investigation.

Purpose of the Study:

  • To determine if sonoelastography is a useful imaging method for evaluating congenital clubfeet.
  • To compare tendon stiffness between clubfeet and normal feet.
  • To observe the impact of treatment methods on tendon elastographic appearance.

Main Methods:

  • A case-control study involving 10 adolescent patients with unilateral idiopathic clubfeet.
  • Compression sonoelastography was used to obtain semi-quantitative fat to tendon ratios.
  • Examined tendons included tibialis anterior, tibialis posterior, flexor hallucis longus, peroneus longus, and Achilles tendon.

Main Results:

  • A statistically significant difference in strain ratio was found only at the calcaneal insertion of the Achilles tendon, which was stiffer in clubfeet (p = 0.023).
  • Other observed differences, though not statistically significant, may indicate pathological changes in clubfeet.
  • The study examined tendons at the calcaneal insertion, lengthened zone, and musculotendinous junction.

Conclusions:

  • Sonoelastography shows potential as a tool for quantitative and qualitative assessment of soft tissue stiffness in clubfeet.
  • Further research is necessary to fully establish its role in clubfoot management.
  • The findings suggest sonoelastography could aid in understanding the biomechanical properties of clubfeet.
