Week 7 Flashcards
Ossification - means what?
Ossification - means how much calcium is present
Periosteum- is what? and what does it contain ?
outer layer of bone and it contains progenitor bone cellS ,blood vessels and nerves
Chondrocytes - do what?
Form cartilage
Fibroblasts form what links ?
collagen links
complication fracture - Nounion meaning \ ?
Ends don’t meet after 6 months
complication fracture - malunion meaning \ ?
Ends meetbut not well aligned
complication fracture - osteonecrosis meaning \ ?
Death of bone tissue
Osteomyelitis
Inflammation of bone caused by infection
What happens during the 5 stages of fracture remodeling ?
1. Haematoma
2. Soft callus
3. Hard callus
4. Consolidation
5. Remodelling
What is a ligament , tendons and fascia
Ligaments - connect bone to bone
Tendons - connect muscle to bones
Fascia - Controls big muscle groups it is essentially continuous with tendons and it’s connecting all the muscle fibres togeather so when they pull , they pull on the tendon
What is compartment syndrome and treatment
Compartment syndrome Where you get damage to the tissue but the real problem is running aronel the outside of the muscle is the EPI museum and in this case it has not ruptured leaving the blood and inflammatory fluid too whereto go it’s stuck inside the fascia - this causes hypoxia and hypoxia leads to even more inflammation The network effect of this is that this increased pressure is going to compress the arteries - if left untreated Can lead to necrosis
Treatment of compartment syndrome
Cut open the muscle
Is hypocalcaemia high or low calcium ?
Low
Main regulator of plasma calcium is which hormone?
Parathyroid hormone
Calcitriol
Calcitriol is a hormone that comes from vitamin D - formed in the Kidney
• Really important for calcium balance because it’s the only thing that can Stimulate greater absorption of calcium from the intestines
Calcitonin
Calcitonin > very important for stimulating bone growth , but it does really maintain calcium levels day today Instead it is involved in an icreaseal calcium deposition into bones When your growing
