Abstract:
The purpose of this study was to assess growth patterns after lengthening of the congenitally short femur or tibia in children younger than 6 years. Twenty such children underwent 28 bone segment lengthenings (13 femora and 15 tibiae) by distraction osteogenesis. Our results show that femoral lengthening in children younger than 6 years does not lead to growth inhibition, whereas isolated femoral lengthening may be associated with growth stimulation. Isolated tibial lengthening in children younger than 6 years does not lead to growth inhibition, whereas simultaneous femoral and tibial lengthening or two tibial lengthenings in close succession can lead to tibial growth inhibition.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
