Summary

A series of 127 trochanteric femoral fractures was analyzed with respect to fracture type, age, and bone quality (osteoporosis). There was a continuous decrease in bone quantity (measured as femoral score) with age and a direct relation between bone quality and the severity of the pattern of the trochanteric fracture. The skeletal ageing process starts earlier in women. However, after the age of 85 years the process is more rapid in men. Consequently, the risk of sustaining a trochanteric fracture is greater in men than in women above this age. The increasing age of the population and the longer survival of the oldest people results in more unstable and more comminuted fractures, which have increased by a factor of nearly 3 during the past three decades.

Zusammenfassung

Eine Serie von 127 pertrochanteren Femurfrakturen wurde hinsichtlich Frakturtyp, Lebensalter und Knochenbeschaffenheit (Osteoporose) analysiert. Mit zunehmendem Lebensalter wurde eine kontinuierliche Abnahme der Knochenmasse (gemessen als Femur-Wert) gefunden. Außerdem bestand ein direkter Zusammenhang zwischen der Knochenqualität und dem Schweregrad des Frakturmusters. Der Alterungsprozeß des Skeletts beginnt bei Frauen früher. Nach dem 85. Lebensjahr jedoch schreitet der Prozeß bei Männern schneller fort. Das Risiko einer pertrochanteren Fraktur ist daher bei Männern in den Achtzigern größer als bei Frauen gleichen Alters. Das zunehmende Lebensalter der Bevölkerung und die längere Lebenserwartung der Alten führt daher zu instabileren Frakturen und ausgedehnteren Trümmerbrüchen. Tatsächlich haben sich these auch in den letzten drei Jahrzehnten beinahe um den Faktor 3 vermehrt.
