What is degenerative joint disease
|
osteoarthritis, most common form of arthritis
intrinsic disease of cartilage and its matrix characterized by progressive erosion of articular cartilage |
|
|
What is rheumatoid arthritis
|
chronic systemic inflammatory disorder
immunlogic factors are key |
|
|
Tissue change characteristic of DJD
|
erosion
fibrillation total loss of cartilage (eburnation) destroyed bone (subchondral cyst) boney outgrowths from edge of articular cartilage (osteophytes) that limit motion and cause pain |
|
|
Tissue change characteristic of RA
|
inflammation of synovium and prolif of syn cells
mass produced called pannus encroachment onto articular cartilage and erosion dustruction of bone obliteration of joint space and fusion of adjacent bones (ankylosis) |
|
|
Osteopenia
|
decrease of bone mass below normal
|
|
|
Osteomalacia
|
defective matrix mineralization associated with nutritional deficit and abnormal met of vit D, UNDERMINERALIZED REMODELED BONE adults, rickets in kids
|
|
|
Osteoporosis
|
reduction in mass of bone per unit volume of bone and micr architectural deterioratio of bone space (increased pores)
net rate of bone loss mineralization is normal |
|
|
Risk factors of Osteoporosis
|
age, sex, loss of estrogen or testoterone,
|
|
|
Paget disease
|
osteitis deformans
sequence of repetitive bone resorption and formation ostelytic osteoclastic - osteoblastic osteosclerotic haphazard mosaic pattern of bone |
|
|
osteonecrosis
|
avascular necrosis or aseptic necrosis
infarct usually in head of femur |
|
|
osteomyelitis
|
inflammation of bone and marrow, implies infection
|
|
|
different types of fractures
|
complete, incomplete, closed or compound, comminuted and displaced
|
|
|
Why is it important to recognize a fibrous cortical defect
|
NOT a neoplasm, although they disappear with age, the can become large and weaken bone and result in fracture
|
|
|
what are the radiographic differences between benign and malignant bone neoplasms
|
benign have sclerotic rim of reactive bone around their periphery
malignant grow rapidly and do not produce layer of reactive bone, cortex is also destroyed |
|
|
most common malignant tumors of bone and cartilage
|
osteosarcoma most common malignant neoplasm of bone
primite neuroectodermal tumor or Eyings sarcoma |
