Document Summary
Fibrous fixed/rigid: sutures, syndesmoses, gomphosis (not entirely fixed) Cartilaginous limited movement: symphyses, synchondrosis. Synovial free movement (apart from sacroiliac joint) Three types: sutures, unossified ligament, eventual synostosis. Syndesmosis: cord-like fibers, slight to moderate movement between bones. Gomphosis: fibrous connection between tooth root and alveolus, limited movement. Two types: symphysis: auricular surfaces covered by thin layer of hyaline cartilage (e. g. pubic symphysis and vertebrae, connected by a plate of fibrocartilage, synchondrosis: bones are directly connected by hyaline cartilage, little to no movement, e. g. Condition of synovial joints due to interruption of normal joint function and stability. View bone tissue that cannot be seen and pattern of density. Subchondral bone is exposed sclerosis develops (eburnation) and become porous, subchondral cysts may develop. Septic arthritis: bacterial infection spread to joint via blood (direct or indirect from wound, 33% knee, 33% hip, 33% other, usually only one joint, staphylococcus or streptococcus, e. g. foot bones, tibia, fibula.
