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...

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

Muscles of the Leg that Move the Foot and Toes

1.7K
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....

Microtubule Instability02:17

Microtubule Instability

5.2K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

3.8K
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...

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Biomechanics

Background:

  • Subtalar instability is a challenging condition frequently associated with lateral ankle instability.
  • Its diagnosis is often difficult due to complex biomechanics and varied clinical presentations.

Purpose of the Study:

  • To elucidate the relationship between subtalar joint kinematics and joint stability.
  • To enhance understanding of the clinical presentation of subtalar instability.
  • To review diagnostic radiographic modalities and surgical treatment options.

Main Methods:

  • Exploration of subtalar joint kinematics and ligamentous contributions to stability.
  • Review of clinical diagnostic criteria for subtalar instability.
  • Evaluation of radiographic imaging techniques and their diagnostic accuracy.
  • Discussion of current surgical management strategies.

Main Results:

  • Subtalar joint kinematics are intrinsically linked to its stability, influenced by both intrinsic and extrinsic ligaments.
  • Accurate diagnosis requires a thorough understanding of clinical signs and appropriate radiographic interpretation.
  • Evidence supports specific radiographic modalities for assessing subtalar instability.

Conclusions:

  • Subtalar instability requires careful clinical evaluation and appropriate diagnostic imaging.
  • Understanding subtalar biomechanics is key to diagnosing and managing this condition.
  • Surgical options are available and require informed patient decision-making based on current evidence.
