It has already been shown in animals and using anatomical human
specimens that chronic slippage of the adolescent upper (capital) femoral
epiphysis is unlikely to take place by shearing due to the presence of an
epiphyseal tubercle projecting down into the metaphysis. Plain radiographs of 20 adolescents and CT scans of 9 of them
were analyzed for evidence of the size and presence of this tubercle in vivo.
These cases showed that CT scanography is the investigation of choice to
illustrate this largely undescribed anatomical feature. They also illustrate the
epiphyseal tubercle well, both in the anatomical position and at various stages
of "epiphyseal slippage", and confirm that it has a significant restraining
effect on any tendency of the epiphysis to alter its position relative to the
metaphysis.
