5. Bone Diseases Osteoporosis excessive loss of calcified matrix
Paget Disease
increased and irregular bone formation
bones become larger and abnormal shape
-due to malnutrition
-pores formed as bone tissue is lost
-bone often grows into marrow spaces causing thickening

6. Bone Fractures (see handout)
open (compound)
closed
complete
incomplete
comminuted
impacted
linear
transverse
oblique
-bone pierces skin, inc. chance of infection
-simple
-bone separates completely
-bones still joined
-breaks that produce many fragments
-bone fragments driven into each other
-parallel to bone
-straight across bone
-on a diagonal

7. Inflammatory Joint Disease (Arthritis)
-redness, heat, swelling, pain
Inflammatory Joint Disease (Arthritis)
rheumatoid arthritis
inflammation of synovial membrane and articular cartilage
severe crippling
infectious arthritis
infection of joint tissues by pathogens
Lyme Disease
-joint membranes
-due to deformity of joints
-disease-causing organisms
-caused by bacterium carried by ticks
-leads to inflammation of joints
