Joint mechanics Flashcards
The three types of joints are:
Fibrous, cartilaginous, synovial
Three types of joint motion are:
Synarthrosis (least), amphiarthrosis (some) and diarthrosis (most)
Two Subtypes of cartilaginous joints are
Hyaline and fibrocartilage
Hyaline is found in:
synovial joints, epiphyseal plates and sternocostal joints
Fibrocartilage is found in:
intervertebral discs
A synchondrosis is:
Where hyaline cartilage connects a cartilaginous joint. Example would be sternocostal joints.
Inflammatory joint degeneration is due to what:
inflammatory condition in which the immune system attacks synovium and cartilage
Osteoarthritis (OA) is:
Joint disease that gets worse over time, not inflammatory, cartilage is eroding allowing bones to rub together
Traumatic joint degeneration is from:
from an injury leading to avascular necrosis and cartilage deteriorates leading to bones rubbing together
Fibrillation is due to
due to loss of proteoglycans
Fibrillation causes what type of appearance of cartilage?
Ground glass appearance
Eburnation is due to
Complete loss of articular cartilage (you “burned” it all away)
Bone is hard and polished and accompanied by thickening of subchondral bone (osteosclerosis) in:
Eburnation
