Term
|
Definition
| A fracture in which the bone has been twisted apart and the line of break is helical. |

| Break at distal end of fibula |
|
|
Term
|
Definition
| Distal end of radius breaks and is displaced backwards |

Definition
| Bones not aligned after break |
|
|
Term
|
Definition
| Bones remain in alignment after break |

Term
| Fibrocartilagenous Callus Formation |
|
Definition
Fibroblast, osteogenic cells, and red marrow invade the procallus
Fibroblast form collagen fiber which help connect broken bones togther
Phagocytes continue to remove debris
Osteogenic cells form chondroblasts which forms fibrocartilage. |
|
|
Term
|
Definition
Osteogenitor cells give rise to Osteoblasts which start to make spongy bone trabeculae
Trabeculae join with living and dead bone fragments
Fibrocartilage is turned into spongy bone |
|
|
Term
|
Definition
Dead fragments of bone are resorbed by osteoclasts
Compact bone replaces spongy bone
A thickened area on the surface of the bone may remain after repair |

Term
|
Definition
| loss of calcium and mineral from extracellular matrix |
