| Question | Answer |
|---|---|
| Grow slowly and don't metastize | Benign Bone Tumors |
| Cause structure to enlarge and impairs function may reoccur in same spot | Benign Bone Tumors |
| Malignant Bone Tumors | Metastasis is thru the circulatory or lymphatic system |
| Most common site is the lungs | Malignant Bone Tumors |
| Amputation | AKA, BKA, AE, OR BE |
| Greatest danger in post-op period | Hemorrhaging |
| Neuroma | Nerves entangled with scar tissue |
| Hematoma | Blood Clot |
| Elevation of Amputation | Check bleeding on top and under, VS important |
| Break in bone from direct or indirect trauma | Fractures |
| Oblique | break runs along a slant to the length of the bone |
| Comminuted | splintered into fragments |
| Spiral | break that coils around the bone |
| Greenstick | incomplete fracture, common in children |
| Impacted | one bone fragment forcibly wedged against another bone fragment |
| Simple | fracture dthat remains contained, does not break the skin |
| Compound | fracture in which damage also involves the skin or mucous membranes |
| Compression | fracture in which bone has been compressed (vertebral fractures) |
| Avulsion | pulling away of a fragment of bone by a ligament or tendon and its attachments |
| Depressed | fracture in which fragments are driven inward (skull and facial bone) |
| Pathologic | fracture that occurs through an area of diseased bone, |
| Crepitus | grating sound of bone ends moving over one another |
| Fracture healing Stage 1 | bleeding occurs immediately with edema, 48 to 72 hrs, hematoma forms between 2 broken ends of bone |
| Fracture healing Stage 2 | hematoma does not reabsorb, other cells enter the clot and granulation tissue forms, gradually becoming firm and making a bridge between the 2 broken ends |
| Fracture healing Stage 3 | end of 1st wk, granulation tissue turns into callus which is made up from cartilage, osteoblast, calcium and phosphorus |
| Fracture healing Stage 4 | 2-3 wks, woven bone forms, ends of broken bone begin to knit. |
| Fracture healing Stage 5 | Excess bone chiseled away by stress to affected part from motion, exercise and weight bearing. bone takes on original shape and size. |
| Condition where fat globules are released from the bone marrow of the broken bone into the blood stream. | Fat Embolism |
| Fat Embolism | occurs 24-48 hrs after injury, most common in long bone fractures, multiple fractures and severe trauma, can be fatal. |
| Older patient with a hip fracture is at highest risk, respiratory distress is first sign | Fat Embolism |
| Malignant Bone Tumors | abnormal osteoblast or myeloblast that exhibit rapid and uncontrolled growth. |
| Usually found around the knee in the distal femur or proximal fibula with a few found in the proximal humerous. | Malignant Bone Tumors |
| Amputation | Removal of body limbs or parts of limbs |
