|---|
| compound fracture | open fracture 1 |
| broken bone that pentrates the skin | open fracdture 2 |
| broken bone does not penetrate the skin | closed fracture |
| break in vertebra in the spine | compression fracture |
| fatigue frature | stress fracture 1 |
| hairline fracture | stress fracture 2 |
| overuse injury, often v.sm. sliver or crack in bone | stress fracture 3 |
| a tendon or ligament attaches to the bone and pulls off a piece | avulsion fracture |
| occurs in developing bone w/ one side of fractrue has broke & one side is bent | greenstick fracture 1 |
| an incomplete break | greenstick fracture 2 |
| break which runs perpendicular to the bone | transverse fracture |
| bone is broken, splintered or crushed into pieces | comminuted fracture |
| opposite sides of the broken bone are compressed together | impacted fracture 1 |
| common with hip fractures & fractures breaking a fall w/outstretched arms | impacted fracture 2 |
| break in the continuity of bone | fracture |
| fracture healing | bone repair |
| bone healing is initiated with bone | death 1 |
| bone healing may also be initiated with damage to | haversian systems blood vessels |
| bone fracture tears & destroys bl. vessels that carry nutrients to | osteocytes 1 |
| dead bone is either removed by resorption or used as a | scaffolding |
| dead bone can be used as scaffolding for special tissue called a | callus |
| vascular damage after a fracture results in a | hemorrhage |
| vascular damage after a fracture forms a blood clot called a | hematoma |
| callus tissue serves to _____ broken ends & stabilize the fracture | bind |
| abnormal amts. of bone tissue growth | bone neoplasms |
| benign cartilage tumor outgrowth, connected to bone by a stalk | osteochondroma 2 |
| osteochondromas generally occur at the end of the growth plates of long bones, often at | joints |
| Osteochondromas often form at the | shoulder or knee, or long bones of forearm |
| one of the most common benign bone tumors | osteochondroma 2 |
| most common type of malignant bone tumor | osteosarcoma 1 |
| often most fatal kind of malignant bone tumor | osteosarcoma 2 |
| osteosarcomas are more frequent in | men |
| 10% of cases of osteosarcoma lead to | metastases 1 |
| distant spread of malignant tissue is called | metastases 2 |
| osteosarcoma often metastasizes to the | lungs |
| when osteosarcoma spreads to the lungs usually results in this in one year | death 2 |
| treatment for osteosarcoma involves | surgery and chemotherapy |
| malignant tumor of hyaline cartilage | chondrosarcoma 1 |
| this is a large bulky slow growing tumor | chondrosarcoma 2 |
| chondrosarcoma is a _____growning tumor | slow |
| chondrosarcoma occurs mostly in | middle aged people |
| chondrosarcoma commonly are located in | femur, spine, pelvis, ribs or scapula |
| treatment for chondrosarcoma | large excisions or chemotherapy |
| excessive loss of calcified matrix , bone mineral & collageneous fibers | osteoporosis |
| thsee stimulate bone growth | testosterone & estrogen |
| testosterone & estrogen levels decresase in the elderly reducing the | amount of new bone production |
| osteoporosis can lead to | fractures and kyphosis |
| why should you wear all black? | It's easier than working out |
