    Description / Table of Contents: Zusammenfassung Bislang wird im orthopädischen Schrifttum vielfach die Hypothese Brocher's (1950) vertreten, daß eine Dysplasie der Wirbelbogenstrukturen Vorbedingung für die Entstehung einer Spondylolyse sei. Neuere Untersuchungen machen deutlich, daß die Wirbelbogendysplasie und die Spondylolyse als Folge eines gestörten Wirbelsäulenwachstums entstehen. Als Störfaktoren werden die evolutionäre Entwicklung vom Vierfüßler- zum Zweifüßlergang, Ermüdungsfraktur der Interartikularportion und Wirbelreifungsstörung im Kleinkindesalter verantwortlich gemacht.
    Notes: Summary The commonly accepted hypothesis set up by Brocher in 1950 that the dysplasia of the pars interarticularis vertebrae is an essential requirement for the occurrence of spondylolysis should be thought over in light of recent findings. Newly published investigations show that disturbed spinal growth leads to dysplasia of the vertebral arch and to spondylolysis. Disturbances that play an important role are biomechanical stress factors that result from the evolution from a quadripedal to a bipedal human locomotion as well as stress fractures of the vertebral pars interarticularis and defects in vertebral maturation in small infants.
