what are the developmental considerations for infants and children?
Bone growth – from in utero through to adolescence when a rapid growth
spurt occurs
* Long bones grow in 2 dimensions: width (diameter) and length
* Skeletal contour changes noted at the vertebral column
* Development of dysplasia of the hip (DDH) - congenital abnormalities of the
hip joint
* Infants should be examined periodically until they are walking
independently
* Several risk factors. Examples: having a first=degree relative with DDH,
breech delivery etc.
* Growing Pains - Noninflammatory pain syndrome affecting children between
ages 3-12
38
what are the developmental considerations for pregnancy?
Increased joint mobility occurs
due to increased levels of
circulating hormones such as
estrogen, relaxing etc.
* Change in posture - lordosis which
compensates for the growing
fetus
39
Reabsorption of bone occurs more rapidly then deposition
after the age of 40 years
osteoporosis
40
Caused by shortening of the vertebral column - due to loss of
water content, thinning of the vertebral discs
decreased height
41
how do we inspect the musculoskeletal system?
Assess size and contour of the joint
* Inspect the skin and tissues over the joint (colour, swelling,
masses, deformity)
* Presence of swelling is significant – indicates joint irritation
* Swelling can be caused by:

ankylosis
42

43
what are the normal findings for palpation of the musculoskeletal system?
Joints not tender to palpation, synovial membrane is not
palpable
* Note: a small amount of fluid is present in the normal joint but it is
not palpable
44
what are the abnormal findings for palpation of the musculoskeletal system?
Warmth, tenderness, palpable fluid, tenderness, thickened
synovial membrane

structures (i.e. muscles, tendons, joint capsule etc.)
