|
BMP's in healing
|
- released when bone is resorbed by osteoclasts
- stimulate osteoprogenitor cells to become osteoblasts - injection into muscle makes an entire new ossicle - a big thing in bone grafts |
|
|
PDGF in healing
|
positive effect on wound and ligament healing
|
|
|
TGF-b1 in healing
|
positive effect on tensile strength of the healing tissue
|
|
|
healing in tendons and ligaments
|
- keep them mobile
- make of collagen, and that can form adhesions |
|
|
partial thickness AC healing
|
- necrosis of hypertrophic cartialge cells nearby
- defects filled w/ fibrin - b/t 2 days and 2 weeks, mitosis for more cartilage cells, but not nearly enough to replace - in time, flattened fiborous cells from superficial zone fill defect |
|
|
full thickness AC healing
|
- adjacent cartilage necrosis
- defect filled w/ blood that clots - filled some w/ superficial cells, BUT - bluk of defect filled w/ granulation tissue - this becomes more fibrous and less vascular, looking more like hyaline cartilage |
|
|
hot and cold technetium bone scans
|
- hot, or increased uptake, w/ a fracture
- cold, or decreased uptake, w/ AVN |
|
|
4 R's of fracture therapy
|
- recognition
- reduction - retention - rehab |
|
|
Sudeck atrophy
|
- vasomotor disorder
- intense pain and spotty osteoporosis - usually relevied by resumption of normal activities - interruption of synp nerve to the part may be necessary |
