Ch.6: Bone and Skeletal Tissue Part 2 Flashcards
Nondisplaced fracture is
bone retains in the their normal position
Displaced fracture is
Bone ends are out of their alignment
Open fracture is
End of bone penetrates the skin
Closed fracture is
End of bone does not penetrate the skin
complete fracture is
bone is broken through the fracture
Incomplete fracture is
Bone is not broken through the fracture
Comminuted fracture is
bone fragments into three or more pieces
Compression fracture is
Bone is crushed
Spiral fracture is
Ragged break occurs when excessive twisting forces are applied to a bone, common in sports fracture
Epiphyseal fracture is
Epiphysis separates from the diaphysis along the epiphyseal plate
Depressed fracture is
broken bone portion is pressed inward, typical skull fracture
Greenstick fracture is
Bone breaks incompletely, common is children
first step to bone repair includes
- hematoma forms
- hemorrage (torn blood vessels)
- clot forms
- swollen, inflamed and painful
2nd Step to bone repair includes
- Fibrocartilagenous callus forms
- phagocytes clear debris
- osteoblast begin forming spongy bone
- fibroblast secrete collage
- fibrocartilaginous callus
3rd Step to bone repair includes
- Bony callus formation
- hard callus
