Study Notes

Medical Terminology for Joints

arthr/o: Refers to joints.
spondyl/o: Relates to the spine or vertebra.
ankyl/o: Indicates stiffness.
scoli/o: Denotes bent.
articulation: The point where two bones connect.

Joint Types

synarthrodial joints: Immovable, such as sutures in the skull.
amphiarthrodial joints: Slightly movable, allowing limited motion.
diarthrodial (synovial) joints: Freely movable joints with a joint cavity.

Synovial Joints

Characterized by a joint cavity lined with synovial membrane and filled with synovial fluid.
Held together by ligaments, with bones cushioned by articular cartilage.
Associated with bursae that protect underlying bones from friction caused by ligaments during movement.

Joint Movements

flexion: Bending the arm.
extension: Straightening the arm.
abduction: Moving the arm away from the body.
adduction: Bringing the arm back to the side.
rotation: Twisting the ankle.
supination: Turning the hands upward.
pronation: Turning the hands downward.
dorsiflexion: Flexing the foot.
plantar flexion: Pointing the toes.
circumduction: Creating a circular motion with the arm.

arthralgia: General term for joint pain.
arthritis: Inflammation of the joints; includes various disorders affecting millions.
- ankylosing spondylitis: A form of arthritis affecting the vertebrae with symptoms like pain, malaise, kyphosis, and loss of height. Treatment involves anti-inflammatory drugs and physical therapy.
- osteoarthritis: The most common type of arthritis, degenerative in nature, mainly affecting weight-bearing joints such as hips and knees. Symptoms include stiffness, pain, and decreased range of motion (ROM); treatment involves medications, physical therapy, and possibly surgery.
- rheumatoid arthritis: A chronic inflammatory disease predominantly affecting non-weight-bearing joints, most commonly seen in women aged 20-40. Symptoms include joint swelling, pain, and stiffness, which may lead to deformity. Treatment options include NSAIDs, rest, and physical therapy, with potential joint replacement.
- gout: An acute form of arthritis primarily affecting the first metatarsal joint of the great toe, related to poor uric acid metabolism. Treatment consists of rest, ice, anti-inflammatory medications, and dietary changes.
- bunion: Abnormal swelling at the base of the great toe due to genetics or ill-fitting shoes, presenting with pain and swelling. Treatment includes preventive measures, orthotics, and possible bunionectomy.

Joint Issues

contracture: A condition where the joint is fixed in a flexed position, leading to muscle shortening and atrophy.
dislocation: Displacement of a synovial joint, resulting in loss of function.
subluxation: Partial dislocation associated with loss of function and pain, often following an injury, treated with closed reduction and immobilization.
ganglion cyst: A fluid-filled nodule that forms under the skin, often on the wrist, caused by leakage of synovial fluid. Treatment options include rest, needle aspiration, or removal.
herniated disc: The nucleus of the intervertebral disc ruptures, causing nerve compression, which can lead to sciatica if the sciatic nerve is affected.
