bone break?

Bone fractures
Answer: There is no difference. They are 2 terms describing the
same thing--- The bone is broke

Bone Fractures
Types:1. Simple2. Compound3. Complete4. Incomplete

Bone Fractures
Complete Fracture- The bone breaks into two or more parts
![Page 6: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/6.jpg)
Bone Fractures
Incomplete Fracture- bone cracks but does not break all the way through.

Bone Fractures
Compound Fracture also called an open fracture the bone breaks through the skin
it may then recede back into the wound and not be visible through the skin

Bone Fractures
Simple Fracture- also called a closed fracture the bone breaks but there is no open wound in the
skin.

Bone Fractures
Simple Fracture- Greenstick :
an incomplete fracture in which the bone is bent. This type occurs most often in children.

Bone Fractures
Simple Fracture- Impacted fracture
is one whose ends are driven into each other. commonly seen in arm fractures in children A.k.a. buckle fracture

Bone Fractures
Treatment: Reduction:
realignment of the broken bone ends
![Page 12: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/12.jpg)
Bone Fractures
ReductionClosed Reduction-
Bones are coaxed back into their normal position by the physician’s hands

Bone Fractures
Reduction- Open Reduction: surgery is performed and bone ends
are secured together with pins or screws
![Page 14: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/14.jpg)
Bone Fractures
Immobilization- After bone is reduced Cast or traction allows the healing process to begin

Bone Fractures
Healing Process:6-8 weeks for a simple fracturemuch longer for large bonesmuch longer for bones of elderly people (poor circulation)

Bone Fractures
4 major events in bone repair
![Page 17: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/17.jpg)
Bone Fractures
Bone Repair step one: Hematoma is formed—
a blood filled swelling caused from blood vessels rupturing when bone breaks
![Page 18: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/18.jpg)
Bone Fractures
Bone Repair step two: Fibrocartilage callus forms—
Cartilage, bone and collagen fibers laid down Acts as a splint Closes the gap
![Page 19: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/19.jpg)
Bone Fractures
Bone Repair step three: Bony Callus formation—
Osteoblasts and osteoclasts come to the area Fibrocartilage is replaced by spongy bone
![Page 20: Bone Fractures. Bone fractures Question: What is the difference between a bone fracture and a bone break?](https://reader035.vdocuments.us/reader035/viewer/2022062304/56649e9e5503460f94ba0586/html5/thumbnails/20.jpg)
Bone Fractures
Bone Repair step four: Bone Remodeling—
In response to mechanical stress Strong permanent bone formed at site of injury
