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.
