The effect of varying degrees of flexor sheath integrity (sheath excised, incised, or incised and repaired) on the uptake of 3H-proline by chicken flexor tendons in Zone II was studied. The tendons were either: normal and uninjured, lacerated and repaired, or uninjured except for vinculum longum ligation. Different degrees of sheath integrity did not influence the uptake of 3H-proline by the tendons. The tendon does not appear to be dependent on a synovial environment for nutrients and is capable of obtaining these nutrients by diffusion from the surrounding extracellular tissue fluid. Diffusion is the primary nutrient pathway to the flexor tendon in this area, because removing its major vascular attachment (i.e., the vinculum longum) did not effect proline uptake. Careful closure of the sheath with restoration of a synovial environment does not appear to be necessary for tendon nutrition.
研究了不同程度的屈肌腱鞘完整性（腱鞘切除、切开或切开并修复）对鸡Ⅱ区屈肌腱摄取³H-脯氨酸的影响。肌腱分为以下几种情况：正常且未受伤、撕裂并修复，或除长腱纽结扎外未受伤。不同程度的腱鞘完整性并未影响肌腱对³H-脯氨酸的摄取。肌腱似乎不依赖滑膜环境获取营养，能够通过从周围细胞外组织液扩散来获取这些营养。在该区域，扩散是屈肌腱获取营养的主要途径，因为去除其主要血管附着结构（即长腱纽）并不影响脯氨酸的摄取。对于肌腱营养而言，似乎没有必要精细缝合腱鞘以恢复滑膜环境。
