Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

2.5K
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: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

5.4K
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...

Ankle Joint01:10

Ankle Joint

1.9K
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...

Deformation of Member under Multiple Loadings01:11

Deformation of Member under Multiple Loadings

221
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

40
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Plastic Deformations01:19

Plastic Deformations

195
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

Area of Science:

  • Orthopaedic Surgery
  • Foot and Ankle Deformities

Background:

  • Traditional terminologies for adult flatfoot deformities can be confusing.
  • Expert surgeons proposed "progressive collapsing foot deformity" (PCFD) to enhance clarity.
  • Existing terms may not fully encompass the complexity of the deformity.

Purpose of the Study:

  • To introduce the new nomenclature for progressive collapsing foot deformity.
  • To present a novel classification system for PCFD to aid surgical decision-making.
  • To summarize recent advancements in PCFD diagnosis and treatment.

Main Methods:

  • Review of consensus statements on surgical goals for PCFD.
  • Summary of recent literature on PCFD reliability and diagnostic accuracy.
  • Analysis of the role of advanced imaging and soft-tissue reconstruction in PCFD.

Main Results:

  • The new PCFD nomenclature and classification system aim to simplify clinical approaches.
  • Recent studies explore the reliability and diagnostic accuracy of PCFD assessment.
  • Advanced imaging and soft-tissue reconstruction are key components in managing PCFD.

Conclusions:

  • The PCFD classification system offers a reproducible method for surgical decision-making.
  • Individualized treatment strategies are essential for this complex 3D deformity.
  • While improvements are needed, the new system aids in managing PCFD.
