Functional Classification of Joints01:09

Functional Classification of Joints

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.

Joints

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.

Ankle Joint01:10

Ankle Joint

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

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...
Knee Joint01:23

Knee Joint

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 group...
Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Area of Science:

  • Rheumatology
  • Gastroenterology
  • Clinical Medicine

Background:

  • Joint hypermobility syndrome is often misperceived as rare.
  • Its prevalence in rheumatology settings is notably high, potentially exceeding other rheumatologic conditions.
  • A significant barrier to diagnosis is the lack of awareness regarding the syndrome and its recognition criteria.

Purpose of the Study:

  • To provide a comprehensive overview of joint hypermobility and joint hypermobility syndrome.
  • To highlight the multisystemic nature of the condition.
  • To emphasize the impact on quality of life, with a focus on gastrointestinal manifestations.

Main Methods:

  • Literature review and synthesis of existing research on joint hypermobility syndrome.
  • Analysis of prevalence data in rheumatology clinics.
  • Discussion of diagnostic challenges and clinical implications.

Main Results:

  • Joint hypermobility syndrome is more prevalent than commonly believed, particularly in rheumatology clinics.
  • The condition affects multiple body systems.
  • Gastrointestinal involvement is a significant aspect impacting patient quality of life.

Conclusions:

  • Joint hypermobility syndrome is a common condition requiring greater clinical awareness.
  • Improved diagnostic strategies are needed to address the underdiagnosis.
  • Understanding its multisystemic effects, including gastrointestinal issues, is vital for patient management.
