osteopathic approach to the pediatric pt (Patty 2) Flashcards
primary flexion curves of thoracic and pelvis caused by what
flexion position of the embryo
extension curves in the ___ and ___ regions are due to
cervical and lumbar
functional muscle development
erectero spinae muscles
C spine has slight lordosis which increases when
as baby can support their own head
by week 24 fetal weeks spinal cord ends at __
at birth ___
in adults ___
S1
L3
L1
ribs and diaphragm in infant
ribs begin anterior
diaphragm inserts horizontally on inner surface of ribs
both become more oblique with aging
what helps to protect the CNS during vaginal delivery
frontal, maxilla, mandible
infants are born with ___ fontanels
name them
anterior
posterior
2 mastoid
2 sphenoid
posterior fontanel closes when
by 2 months of life
anterior fontanel closes when
by 2nd year of life
occipital changes
flexion of the basicranium
30 degres in infants
51 degrees in adult
this flexion creates supralaryngeal space, affects speech, greater in adults so can speak
occiput has __ parts
4
temporal changes (petrous part) how many parts at birth? growth does what?
what cranial nerves pass through it?
3 parts at birth
growth of petrous portion rotates external auditory meatus into the sagittal plane
tips eustachian tube from horizontal position to an oblique angle
CN III-XII
which cranial bone is most susceptible to dysfunction at birth
occiput
what cranial nerves may be injured during forceps delivery and why
CN VI and VII
mastoid process not formed completely which usually protects
what CNs may be impinged by occipital bone dysfunction
what problem with each
9-12
IX- poor sucking
X- excessive vomiting
XI- colic, poor sucking (occipital temp bone dysfunction)
XII- poor sucking bc of tongue dysfunction
temporal bone: ____ associated with increased incidence of otitis media
how to diagnose
internal rotation
cradle occiput and place fingers on mastoid portion of SCM attachment
if one side more prominent then internal rotation of temporal bone on that side
ossification increases and some bones become fused
what age?
toddlers (1-4)
cranium fully ossified
epiphyseal plates still open
growing bones from long bone growth
possible leg length discrepancy
age?
school age children
3 types of growth areas bones
epiphyseal growth plate
epiphysis/articular surface
apophysis
epiphyseal growth plate made of
hyaline cartilage
epiphysis/articular surface made of
hyaline cartilage
apophysis made of, can create
fibrocartilage
creates bony tubercles
avulsion fractures are more common in pediatric pts bc of what
unossified apophysis
-apophysitis
