dislocation – one bone pulled out of socket

bursitis – inflammation of synovial membrane of joint

ArthritisArthritisinflammatory or degenerative

immune tissue erodes cartilage Scar tissue fuses to bones.

◦3 times more common in women◦wrists, fingers, ankles, feet

as needle-shaped crystals in soft tissue of big toe

Bone DisordersBone Disordersgiantism –

excessive growth of long bones

dwarfism – adults under 4’ 10”

osteomyelitis ◦ bone

inflammation◦ caused by

bacterial infection

osteogenesis imperfecta ◦ genetic disorders◦ produce very

brittle bones due to insufficient collagen

carpal tunnel syndromecarpal tunnel syndromeanterior side of

wristtunnel formed by

bones and ligaments

Trauma or overuse cause inflammation in tunnel and fluid put pressure on nerves.

osteoporosisosteoporosisreduction in

overall quality of bone tissue◦ loss of bone mass◦ deformed bones◦ prone to fracture

By age 40◦ women lose ½

bone mass.◦ men lose ¼ .
