Broken Bone victim
Ran and fell forward
landed on right arm
Poor diet and nutrition
lactose intolerant
possible rickets disease
compound fracture
bone protruding from the skin
arm will need to be stabilized
splint will be needed for broken area
occured in upper arm
boy is 12 so bones aren't fully developed
long bone fracture
severe pain
possible infection since skin is pierced
swelling
loss of movement in arm
possible bone infection
long bones
diaphysis
Medullary Cavity
Epiphysis
proximal
distal
Articular Cartilage
Metaphysis
Contains Epiphyseal disc/growth plate
Provides lengthwise bone growth
epiphyseal plate
area of hyaline cartilage in immature bone where ossification occurs
Bones remodel through adulthood
5-10% of skeleton replaced yearly
Influenced by hormones and mechanical stress
Mechanical stress required for normal bone modeling
Increases bone strength (exercise)
Osteoblasts replace resorbed bone
Fracture hematoma
blood clotted within 6-8 hours
Intenal and external callus formation
chondrocytes secrete fibrocartilaginous matrix between two broke ends
hyaline catilage and bone is formed around the break
cartilage replaced by trabecular bone
compact bone replaces trabecular bone
takes several week
Hematoma
Fribrocartiliginous callus and new blood vessel forms
Bony Callus forms
Bone remodeling occurs
Lack of vitamin D
calcium and vitamin D work together
Vitamin D transferred to D3 by kidneys
poor nutrition
junk food does not contain sufficient calcium and minerals
lack of calcium makes bones weaker
lack of dairy and green vegetables
calcium homeostasis
Vitamin K supports bone mineralization
Fluoride helps strengthen bone too
