Ankle Joint01:10

Ankle Joint

3.1K
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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

7.3K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

3.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.2K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints

35.9K
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
The bones of a...

Method of Joints01:30

Method of Joints

1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...

Summary

Varus ankle osteoarthritis shows subtalar joint compensation, with a more valgus alignment observed. This compensation mechanism in the subtalar joint does not change with the stage of ankle osteoarthritis.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Radiology

Background:

  • Ankle osteoarthritis (OA) is a degenerative joint disease affecting lower limb function.
  • The subtalar joint's role in compensating for ankle deformities in OA is poorly understood.
  • Weightbearing computed tomography (CT) offers insights into joint alignment under load.

Purpose of the Study:

  • To investigate subtalar joint alignment in various stages of ankle OA.
  • To determine if the subtalar joint compensates for ankle deformities (varus/valgus).
  • To assess the relationship between subtalar joint compensation and OA stage.

Main Methods:

  • Weightbearing CT scans were used to assess subtalar joint alignment.
  • 88 patients with ankle OA and 27 healthy controls were included.
  • Patients were subgrouped by ankle deformity (varus/valgus) and OA stage.

Main Results:

  • Patients with varus ankle OA exhibited a more valgus subtalar joint alignment.
  • No significant differences in subtalar joint alignment were found across different OA stages.
  • The study identified a compensatory mechanism in the subtalar joint for varus ankle deformities.

Conclusions:

  • The subtalar joint demonstrates compensatory alignment in response to varus ankle deformities in osteoarthritis.
  • Subtalar joint compensation is present regardless of the stage of ankle osteoarthritis.
  • Understanding these compensatory mechanisms is crucial for managing ankle OA progression.
