Summary

The spontaneous degeneration of the human rotator cuff seems to have mechanical and nutritive causes. Untill now it was not known whether other species without an acromion had a vascularization of the rotator tendons which is similar to that of man. We therefore investigated the rotator cuff of dogs microangiographically. The results show a characteristic vascular pattern in each of the rotator tendons which is similar to that of man. Most important is the fact that the supra-spinatus tendon shows an area of hypovascularity close to its insertion. Thus, the dog may be used for experimental purposes relating to the rotator cuff.

Zusammenfassung

Die natürliche Degeneration der menschlichen Rotatorenmanschette hat wahrscheinlich mechanische und nutritive Ursachen. Es war bisher unbekannt, ob andere Spezies, denen das Acromion fehlt, eine ähnliche Gefäßversorgung der Rotatorensehnen aufweisen wie der Mensch. Wit haben deshalb die Rotatorenmanschette des Hundes microangiographisch untersucht. Das Ergebnis zeigt ein charakteristisches Gefäßmuster bei jeder der Rotatorensehnen. Besonders wichtig erscheint eine Zone der Hypovascularisation in der Nähe des Supraspinatussehnenansatzes, wie es auch beim Menschen beschrieben wurde, so daß der Hund für experimentelle Untersuchungen an der Rotatorenmanschette geeignet erscheint.
