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.
What type of fracture is at the distal end of the lateral forearm bone; 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.
