Between the years 1949 and 1968 75 children with unilateral idiopathic LCPD were treated nonoperatively in the Orthopedic University Clinic of Freiburg. In the follow-up 1981 the pelvic teardrop distances were determined and the quotient of the measurement's results of the sick and healthy sides were named “tear drop distance quotient” (TDDQ). We compared this TDDQ with the clinical and radiological end result.

In den Jahren 1949 bis 1968 wurden in der Orthopädischen Universitätsklinik Freiburg 75 Kinder wegen einer einseitigen Perthesschen Krankheit konservativ behandelt. Bei der Nachuntersuchung 1981 wurden der Tränenfigur-Abstand ermittelt und die Meßergebnisse der betroffenen und der gesunden Hüfte miteinander in Beziehung gesetzt. Dieser Quotient (TDDQ) wurde mit dem klinischen und röntgenologischen Endergebnis verglichen.
