rheumatoid arthritis (RA)

most crippling form of arthritis characterized by a chronic, systemic inflammation most often affecting joints and synovial membranes (especially hands and feet) causing ankylosis (stiff joints) and deformity

gouty arthritis

acute attacks of arthritis usually in a single joint (especially great toe) caused by hyperuricemia (excessive level of uric acid in the blood)

bony necrosis, sequestrum

dead bone tissue from loss of blood supply can occur after a fracture


swelling of the joint at the base of the great toe caused by inflammation of the bursa


inflammation of a bursa

carpal tunnel syndrome

open fracture

compound fracture; a broken bone with an open wound

infection of bone and bone marrow causing inflammation


condition of decreased bone density and increased porosity, causing bones to become brittle and liable to fracture


abnormal posterior curvature of the thoracic spine (humpback condition)


abnormal anterior curvature of the lumbar spine (sway-back condition)


abnormal lateral curvature of the spine (S-shaped curve)
