Osteoarthritis“wear and tear” • Breakdown/loss of cartilage between joints • Acquired degenerative process • Managed by first line medications (acetamenophen)
Osteoarthritis - Risk Factors • Age older than 50 • Crystals in joint fluid or cartilage • High bone mineral density • History of immobilization • Injury to the joint • Joint hypermobility or instability • Obesity (weight-bearing joints) • Peripheral neuropathy • Prolonged occupational or sports stress
Rheumatoid Arthritisautoimmune disease • “synovial membranes inflamed” • White blood cells destroy cartilage • Scar tissue forms and then ossifies
Gouty Arthritisaccumulation of uric acid crystals in the synovial fluid • White blood cells engulf the uric acid crystals • Causes pain, heat, redness of tissues
Carpal Tunnel Syndrome • Median nerve becomes pressed or squeezed
Cleft Palate • Palatine process does not fuse • Genetic and environmental factors • Can folic acid reduce chance?
Bursitis • Inflammation of the bursa (small bag of fluid at joints)
Bone Spurs • Bony projections (osteophytes) that grow around joints
Bone Cancer • Osteosarcoma • Ewing's sarcoma • malignant fibrous histiocytoma • chondrosarcoma.
