Where does fracture and fracture repair occur?
|
Areas that are mitotically active`
|
|
|
What is the most common type of bone injury?
|
Fracture
|
|
|
What are used to diagnose fractures?
|
X-rays or roentgenograms or radiographs
|
|
|
What is a stress fracture?
|
a thin break caused by increased physical activity in which the bone experiences repetitive loads, such as running. ex. marathon runner.
|
|
|
Which type of fracture will a runner experience?
|
Stress fracture
|
|
|
What is another name for a pathologic fracture and what causes it?
|
Spontaneous fracture, can occur when a bone is weakened by disease (cancer, osteporosis) ex. in older people, they just fall to the floor because bones are so brittle
|
|
|
What type of fracture is responsible for a elderly woman spantaneously falling to the ground?
|
A pathologic fracture or spontaneous fracture
|
|
|
Closed fracture
open fracture comminuted fracture spiral fracture greenstick fracture depressed fracture displaced fracture nondisplaced fracture |
no break in the skin
break in surface of skin bone is splintered in many pieces bone is broken with twisting movement causing helical cracking incomplete break with bowing portion of teh bone is driven inward fragments are out of proper alignment fragments are in anatomical alignment |

What does the medical treatment involve when a bone fractures?
|
Involves realigning the broken ends and then immobliizing the injured area until new bone tissue is formed and the fracture is healed. The repair of the bone occurs naturally within the bone itself in the following weeks.
|
|
|
What type of of medical treatment requires surgery to restore the bone to anatomical alignment?
|
Open reduction
|
|
|
What is a pott fracture?
|
fracture at the distal end of teh tibia, fibula, or both
|
|
|
what is a colles fracture?
|
Fracture at the distal end of the lateral forearm bone (radius); produces a dinner fork deformity.

Colles fracture

|
What are the 4 steps of the healing process of bone?
|
1. A Fracture hematoma forms when bv's inside the bone and in the periosteum are torn.
2. The traumatized area is cleaned up by phagocytic bc's and by osteoclasts that resorb the bone fragments. a soft fibrocartilage callus forms to bridge the gap of the injured bones. Osteoblasts begin ossifying the cartilage and soon a hard "bony callus" forms in the injured area. 4. Remodeling of the injured area. The excess callus is broken down, a new vascular system is established, and a compact bone develops around the periphery of the fracture. |
