The Skeletal System Pathophysiology Flashcards
What is a fracture
When more mechanical stress is put on a bone than it can handle
When the broken bone pierced the skin it’s called
Open
When the bone is broken but has not pierce the skin it’s called
Closed
When the bone is still partially join together it’s called
Incomplete
When the bone pieces are completely separated from each other it’s called
Complete
When the two ends are still aligned with each other it’s called
Nondisplaced
When the two ends are out of alignment with each other it’s called
Displaced
What is the creation of haematoma
Bleeding from blood vessels of the osteon central canals and the porosity and creates a blood clot
What does fibrocartilaginous callus do
Holds bone ends in place
What connects bone ends with collagen fibres
Fibroblasts
The four steps of bone healing
Creation of hematoma
Formation of fibrocartilaginous callus 
A boney callus forms
Bone remodelling takes place
What is osteoporosis
When the rate of bone resorption is greater than the rate of bone deposition
Risk factors of osteoporosis
Insufficient bone stress Decreased sex hormones Diet poor in calcium or vitamin D Smoking/alcohol consumption Certain medication‘s Genetics
What is the weakest part of the skeleton
Joints
Joint pathophysiology can come from
Traumatic injuries
Inflammatory/degenerative condition
How do you traumatic injuries happen
Stress of tears on the muscle and connective tissue
Examples of traumatic injuries
Sprain
Dislocation
What is a sprain
Acute injury to the ligament of a joint
What is a dislocation
When two bones of a joint no longer make proper contact
What is osteoarthritis
A condition caused by wear and tear around the joints
What is rheumatoid arthritis
When they connective tissues are always inflamed
