Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

1.4K
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...

Joints

33.0K
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

Knee Joint01:23

Knee Joint

1.9K
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...

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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

3.6K
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...

Area of Science:

  • Orthopedic surgery
  • Minimally invasive procedures

Background:

  • Surgical instrumentation and techniques are advancing.
  • Arthroscopic procedures are increasingly utilized.

Purpose of the Study:

  • To highlight the growing role and benefits of arthroscopy in surgical procedures.

Main Methods:

  • Direct, magnified visualization of pathology.
  • Minimizing soft tissue stripping compared to open approaches.

Main Results:

  • Arthroscopy provides superior visualization and accuracy over intraoperative fluoroscopy.
  • Reduced soft tissue disruption protects vascularity, especially in small fracture fragments.

Conclusions:

  • Arthroscopy is a valuable technique due to enhanced visualization and tissue preservation.
  • It is particularly advantageous for managing fractures with delicate vascularity.
