Disorders of Pivot Joints
Pivot joints are a type of there synovial joint that allows for rotation around a single axis. Pivot Joints sometimes get damaged due to physical stress or can get infected with infection or other disease. The major illnesses are listed below:
- Twists and pulls: Tendons and Ligaments are important components of the skeletal and muscular system. These support pivot joints and any damage to these causes a strain or sprain. If tendons get stretched or ripped, it results in a Strain. On the other hand, breakage of ligaments leads to a Sprain. Unexpected trauma or overuse are frequently the culprits of sprains and strains.
- Dislocation: Sometimes while playing or when in an accident, the joint’s bones move out of their usual alignment. This is known as Dislocation. If left untreated, dislocations can be extremely painful and lead to joint injury.
- Arthritis: Sometimes the joints get inflamed due to infections or autoimmune diseases. This joint inflammation is known as Arthritis. Rheumatoid Arthritis is the most common type that affects Pivot Joints.
- Fractures: Two bones join together to form a joint. If there are cracks in the bone, then these are called Fractures.They can be caused by trauma, such as a fall or a car accident.
- Instability: If a pivot joint is loose and may dislocate, it causes instablity. Instability can make it difficult to perform everyday activities and can increase the risk of further injury.
- Articular surfaces could over time decay due to constant movement and joint stress.
Pivot Joints: Definition, Diagram, & its Examples
Pivot joints are those joints that show movement in a single direction. Joints are points of contact between bones. The joint acts as a fulcrum that helps in dispersing the force generated by the muscles. The Pivot joint is a type of Synovial joint that is characterized by the presence of synovial fluid. Other types of Synovial joints are Ball and Socket Joints, Hinge Joints, and Gliding Joints. One example of the pivot joint is the joint between the atlas and the axis. Another Pivot joint in the human body is made of the bones in the wrist.
