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.

Ankle Joint01:10

Ankle Joint

3.8K
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...

Knee Joint01:23

Knee Joint

3.8K
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...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

2.8K
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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

10.0K
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...

Summary

Metacarpophalangeal joint arthroscopy effectively reduces pain and improves function in rheumatoid arthritis and early degenerative arthritis. Patient satisfaction is high, particularly in rheumatoid arthritis cases, with promising outcomes for posttraumatic conditions.

Area of Science:

  • Orthopedic Surgery
  • Rheumatology
  • Arthroscopy

Context:

  • Metacarpophalangeal (MP) joint arthroscopy is a minimally invasive procedure.
  • Indications include rheumatoid arthritis (RA), degenerative arthritis, and posttraumatic conditions.
  • Contraindications involve significant biomechanical changes or active infections.

Purpose:

  • To evaluate the efficacy of MP joint arthroscopy for pain reduction and functional improvement.
  • To assess patient satisfaction across various MP joint pathologies.

Summary:

  • 106 MP joint arthroscopies were performed between 2009-2011.
  • Procedures included synovectomy, loose body extraction, and scar resection.
  • Surgical technique involved dorsal portals, arthroscopic visualization, and radiofrequency ablation if needed.
  • Immediate postoperative mobilization was initiated.

Impact:

  • High patient satisfaction reported, especially in rheumatoid arthritis (RA) and early degenerative arthritis.
  • Results were favorable even with advanced radiologic changes in RA (Larsen stages 1-3).
  • Outcomes in posttraumatic cases show promise.
