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

Muscles of the Leg that Move the Foot and Toes

1.3K
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....

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

2
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...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

2.8K
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...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

1.2K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Ankle Joint01:10

Ankle Joint

1.4K
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:

  • Podiatric medicine
  • Diabetology
  • Public health

Background:

  • Diabetes mellitus affects over 34.2 million people in the U.S. (10.2% of the population).
  • Diabetic foot pathology results in over 150,000 lower extremity amputations each year in the U.S.
  • Infections frequently originate from external shearing forces on deformities of the lesser toes.

Purpose of the Study:

  • To highlight the prevalence of diabetes and its severe complication, diabetic foot pathology.
  • To identify the common initiating factor for diabetic foot infections.

Main Methods:

  • Analysis of epidemiological data on diabetes prevalence.
  • Review of clinical data on lower extremity amputations.
  • Examination of biomechanical factors contributing to diabetic foot pathology.

Main Results:

  • Over 34.2 million individuals in the United States have diabetes.
  • More than 10.2% of the U.S. population is affected by diabetes.
  • Diabetic foot pathology necessitates over 150,000 lower extremity amputations annually in the U.S.

Conclusions:

  • Diabetes is a major public health concern in the United States.
  • Diabetic foot pathology is a significant cause of lower extremity amputations.
  • Shearing forces on toe deformities are a primary initiator of diabetic foot infections.
