    Study Notes

    Skeletal Development

    • The period of skeletal development characterized by structures increasing in size is postnatal growth.
    • Primary curves are associated with the thoracic and sacrum parts of the spine.
    • The joint in the lower limb that is relatively unstable at birth is the ankle joint.
    • During postnatal growth, the depth of the acetabulum increases.
    • The femoral neck inclination increases from birth to adulthood.

    Limb Development

    • The medial longitudinal arch (MLA) develops between 2 and 6 years of age.
    • The development of the MLA occurs during the postnatal period.
    • The development of the MLA matures at around 6 years of age.
    • The tibiae rotate inward after birth, a process known as medial tibial torsion.

    Bone Growth

    • Appositional bone growth is stimulated by growth hormone.
    • Epiphyseal growth in bones is stimulated by thyroid hormone.
    • The cartilaginous skeletal template forms during the embryonic period.

    Skull Development

    • The growth rate of skeletal and muscular development is fastest during the first year of life.
    • Calvarial expansion is most pronounced during the first 6-7 years of skull development.

    Lower Limb Development

    • Developmental variations in the lower limb are often mistaken for deformities.
    • The direction of the femoral neck is characterized by its anteversion and inclination.
