6 major categories of bone pathology
DEFINITION 9
- Congenital2. Inflammatory3. Metabolic4. Neoplastic5. Traumatic6. VascularA seventh category, miscellaneous, encompasses those conditions that do not fall strictly into one category, such as osteoarthritis. TERM 10
Radiographic diagnosis of skeletal pathology
begins with what?
DEFINITION 10 defining the distribution of the lesion applying predictor variables to the lesion
epiphysis
The epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s). TERM 17
diaphysis
DEFINITION 17 The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). TERM 18
metaphysis
DEFINITION 18 The metaphysis is the wide portion of a long bone between the epiphysis and the narrow diaphysis. It is considered a part of the growth plate, the part of the bone that grows during childhood and as it grows, it ossifies near the diaphysis and the epiphyses. TERM 19
Behavior of lesion
DEFINITION 19 osteolytic -- bone destroyed by osteoclastsosteoblastic -- new bone or reparative bone TERM 20
Locus within a bone
DEFINITION 20 epiphysismetaphysisdiaphysisarticular surface
Margin of lesion
sharp defined -- slow growing benignpoorly defined -- fast growing malignant TERM 22
Shape of lesion
DEFINITION 22 longer than wide -- slow growingwider than long -- aggressive cortical breakthrough no breakthrough TERM 23
Joint space involvement
DEFINITION 23 tumors don't cross joint spaceinfections do cross joint space TERM 24
Where does lung and breast cancer spread
to?
DEFINITION 24 thoracic spine TERM 25
where does prostate cancer spread to?
DEFINITION 25 lumbar spine
Gibbus deformity
often used to define a sharp angle in the back with 1 or 2 vertebrae involved TERM 32
Dowagers hump
DEFINITION 32 often used for 3 or more vertebrae TERM 33
buffalo hump
DEFINITION 33 involves fat and is seen in Cushings disease. TERM 34
Infections of the musculoskeletal system can
be divided how?
DEFINITION 34 Infections of bone (osteomyelitis)Infections of joints (septic or infectious arthritis)Infections of soft tissues (cellulitis, myositis) TERM 35
