The perfusion and diffusion pathways to the flexor profundus tendons of 40 monkeys were investigated by measuring the uptake of tritiated proline by various tendon segments. In the absence of all vascular connections, the process of diffusion provides nutrients to all areas of flexor tendon and in this study the process of diffusion was greater. The distal segment of tendon was observed to be profused most rapidly. The proximal tendon segment is perfused from both the muscular-tendinous junction and the vinculum longus; vincular segment perfusion is via the vinculum longus vessels alone; central segment perfusion is shared by the vinculum longus and vinculum brevis vasculature. The distal segment uptake is by both the process of diffusion or vinculum brevis perfusion. The osseous attachment at the distal phalanx contributes little to tendon nutrition.
通过测量不同肌腱节段对氚标记脯氨酸的摄取，研究了40只猴子屈指深肌腱的灌注和扩散途径。在没有所有血管连接的情况下，扩散过程为屈肌腱的所有区域提供营养，在本研究中扩散过程更强。观察到肌腱的远端节段灌注最快。近端肌腱节段由肌肉-肌腱连接处和长腱纽供血；腱纽节段仅通过长腱纽血管灌注；中央节段灌注由长腱纽和短腱纽血管共同提供。远端节段的摄取是通过扩散过程或短腱纽灌注。远端指骨的骨性附着对肌腱营养贡献很小。
