Abstract

Ultrastructural evaluation of the collagen of the mongrel dog medial collateral ligament associated to the oblique ligament after strain. The present work aimed to observe the disposition of the collagen fibres of the medial collateral ligament of the elbow joint of the dog, when associated to the oblique ligament. Thus, 18 articulations were used, divided in three groups. A group had the medial collateral ligament collected and not stretched, other group had the collateral medial ligament stretched separately and the other group had both ligaments (medial collateral and oblique) stretched associately. The medial collateral ligament examined by scanning electron microscopy presented a wavy and reticular pattern of the collagen fibres when not submitted to strain, which was not totally destroyed when it was associated to the oblique ligament. When stretched separately, the medial collateral ligament after strain totally loses the reticular pattern, demonstrating the waste of the fibres to resist to the tension
