Growth then remains constant for several years until the onset of the pubertal growth spurt, which occurs some 2 years earlier, on average, in girls than in boys. Height is dependent on the rate of growth and is com- pared against standardized values. These standardized values are based on the statistical analysis of very large populations. Unfortunately, most of the corresponding tables are already several years old and, given the phe- nomenon of acceleration, no longer accurately reflect the current situation, since children now grow taller, on aver- age, than they did 20 years ago ( Chapter 1.

Certain illustrations show evidence of the presence of poliomyelitis [1, 3, 7–9]. Hippocrates (born in 370 BC) was the first to provide a written record of diseases. He would have been well acquainted with congenital conditions such as clubfoot, hip dislocation and scoliosis. Traumatology and tubercu- losis played an important role even during that era. Bone curvature in children was described in the early post- Christian period (around 110 AD) by Soranus of Ephesus – evidently referring to rickets. It was only in 1650 that this disease was eventually described in detail in Glisson’s treatise. Rickets doubtless played a substantial role in past centuries, primarily in northern countries. Nevertheless, while Glisson believed that the curva- ture of the spine was also attributable to this condition, this was likely to be the case in only a few instances.
