Summary

Fine structural alterations of collagen fibers were analyzed in 29 ruptured tendons. The most frequent alterations were longitudinal splitting, disintegration, angulation, and the so-called “Knickdeformation” of the collagen fibers. All these phenomena were considered to be the consequences of stress fatigue and mechanical injuries of fibers.

Zusammenfassung

In 29 rupturierten Sehnen wurden ultrastrukturelle Abweichungen der Kollagenfasern gefunden. Am häufigsten kamen longitudinale Auffaserungen des Fibrillums, Desintegration der Fasern, sog. Knickdeformation und Brechung der Fasern vor. All diese Erscheinungen werden als Folge der mechanischen Ermüdungsschädigung der Kollagenfasern betrachtet.
