  • Title: [The distribution of cartilage thickness in the distal part of the elbow joint and its functional significance].
    Author: Oberländer W, Kurrat HJ.
    Journal: Morphol Med; 1982 Feb; 2(1):45-52. PubMed ID: 7177138.
    Abstract:
    The cartilage thickness of the proximal articular surfaces of radius and ulna was examined in 10 human elbow joints, and its distribution was analysed from the functional point of view. The thickness of the cartilage covering of the caput radii increases towards its margin, the greatest thickness beeing found in the ventro-ulnar part. The semilunar notch of the ulna showed the thickest covering in the volar portion on the radial side, likewise the olecranon was relative thickly covered with cartilage. Intermediate there was a zone either with an extremely thin or lacking cartilage covering. After the representation of the individual subjects the average distribution of cartilage thickness was computed. The result was discussed according to Pauwels calculations of the functional stress of the elbow joint. It was proved that, basing on the theory of the causal histogenesis of the supporting and connective tissues there was an in general good conformity. The cartilage free groove is explained by the conception of the loss of congruity due to functional cartilage swelling.
