List the six types of bone fractures. | comminuted, compression, depressed, impacted, spiral, greenstick |
Comminuted fracture | Bone breaks into many fragments. (common in brittle bones) |
Compression fracture | Bone is crushed. (common in porous/osteoporotic bones) |
Depressed fracture | Broken bone is pressed inward. (e.g. pushed in skull fracture) |
Impacted fracture | Broken bone ends are forced into each other. (e.g. when arms are outstretched to break one's fall) |
Spiral fracture | Ragged break due to twisting forces on the bone. (common sports fracture) |
Greenstick fracture | Incomplete break, one side of bone unbroken, much like the way a green twig breaks. (common in the flexible bones of children) |
