Previous perfusion studies of the rotator cuff have demonstrated an area of hypovascularity in the distal part of the supraspinatus tendon. This has been implicated in the pathogenesis of its rupture. We performed a quantitative histological analysis of the vascularity of the tendons of supraspinatus and infraspinatus. Vessel number, size and the percentage of the tendon occupied by vessels were measured at 5 mm intervals from the humeral insertions to the muscle bellies. Both tendons were hypovascular in their distal 15 mm. No significant difference was demonstrated between the vascularity of supraspinatus and infraspinatus. We conclude that factors other than vascularity are important in the pathogenesis of supraspinatus rupture.
先前对肩袖的灌注研究表明，冈上肌腱远端存在血管减少区域。这与肩袖破裂的发病机制有关。我们对冈上肌和冈下肌肌腱的血管进行了定量组织学分析。从肱骨附着点到肌腹，每隔5毫米测量血管数量、大小以及血管占肌腱的百分比。两根肌腱在其远端15毫米处均血管减少。冈上肌和冈下肌的血管情况之间未显示出显著差异。我们得出结论，在冈上肌破裂的发病机制中，血管因素以外的其他因素很重要。
