child falls forward while playing and lands on his right arm leaving him with two separate fractures
the indirect reasons for the kid breaking his arm so easily would be his diet. and the direct would be the force of the fall
downstream
the fracture on the upper part of the humerus is a compound fracture due to the fact that the bone has penetrated the integumentary system.
the age of the boy and the fact one of the fractures is towards the top of the humerus could mean that there is possible damage to the epiphyseal plate possibly stunting or affecting the growth of his right arm
the second fracture is distal to the shoulder and involves the elbow
the diet of the boy and his lactose intolerance means he is most likely deficient in the needed nutrients to heal his bone correctly.therefore hell need to be put on vitamins so his body will have the support to heal well
your typical long bone is comprised of compact bone, spongy bone, the diaphysis, the epiphysis, the epiphyseal disk/line (depending on age) , and the medular cavity
bone is formed by three main cells: osteoblasts, osteocytes, and ostoeclasts
bone formation: bone is formed in five steps
1-a bone collar forms around the diaphysis of the hyaline cartilage model
2- Cartilage calcifies in the center of the diaphysis and then develops cavities
3-The periosteal bud invades the internal cavities and spongy bone forms
4-The diaphysis elongates and a medullary cavity forms.
5-The epiphyses ossify
long bones grow longwise through the epiphyseal disk and width wise through appositional growth. being fueled by calcium and vitamin D
the epiphyseal plate/disk is located on either side of a long bone and starts off as hyaline cartilage and slowly starts to ossify when the body releases growth hormones.
kinds of bone fractures:
incomplete-bone is not broken through
comminuted-bone is in more than two pieces
complete-bone is broken through
greenstick-bone is incompletely broken with splintering
compound-broken ends penetrate the skin
fissured-bone has an incomplete longitudinal break
simple- broken ends do not penetrate the skin
spiral- bone is brought about in a twisting action
breaks can be categorized by position of the bone ends, completeness of the breakn, and whether the bone ends penetrate skin
stages of bone healing
Fibrocartilaginous callus forms connecting broken ends splinting bone
Bony callus forms by replacing fibrocartilagineous callaus
a hematoma forms brcause of torn blood vessels in the bone and periostium
Bone remodeling occurs
