Joints

32.5K
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

Structural Joints: Cartilaginous Joints

2.1K
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...

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...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Knee Joint01:23

Knee Joint

1.4K
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...

Structural Classification of Joints01:20

Structural Classification of Joints

3.1K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Area of Science:

  • Orthopedic surgery
  • Podiatric medicine
  • Traumatology

Background:

  • Chopart joint injuries are rare but complex, involving both bone and ligamentous structures.
  • Missed or improperly managed Chopart joint injuries have a high risk of complications.

Purpose of the Study:

  • To emphasize the importance of accurate diagnosis and treatment for Chopart joint injuries.
  • To highlight factors influencing successful long-term outcomes in managing these complex foot fractures and dislocations.

Main Methods:

  • Review of fracture and dislocation patterns in the Chopart joints.
  • Analysis of treatment strategies focusing on articular congruency and mechanical stability.
  • Evaluation of fixation hardware options based on injury characteristics.

Main Results:

  • Chopart joint injuries often present with combined trans-osseous and ligamentous components.
  • Successful treatment necessitates reconstruction of joint congruency and foot realignment.
  • Fixation methods are tailored to fracture type, location, and soft tissue conditions.

Conclusions:

  • Early identification and anatomical fixation are crucial for optimal outcomes in Chopart joint injuries.
  • Inadequate treatment significantly increases the likelihood of complications.
  • Achieving mechanical stability in both foot columns is essential for successful recovery.
