The macroscopic arterial vascularization of the extensor carpi radialis brevis tendon was investigated in 12 elbows from cadavers to provide fundamental anatomic information of this tendon which has been associated with lateral epicondylitis. The arterial blood supply of the extensor carpi radialis brevis tendon was highly consistent. The radial recurrent artery vascularized the entire proximal tendon through direct branches to the medial and lateral border of the tendon forming a network of small vessels on the surface of the tendon. Important contributions were provided by the posterior branch of the radial collateral artery, and minor contributions were provided by the interosseous recurrent artery. The undersurface of the tendon seemed almost avascular. This observation suggests that potential hypovascular zones might be located at the undersurface of the tendon causing degeneration and partial tear of the tendon, and that this might be an etiologic factor in the pathogenesis of lateral epicondylitis. Additional microvascular studies are necessary to investigate this hypothesis.
对12具尸体肘部的桡侧腕短伸肌腱的宏观动脉血管分布进行了研究，以提供与外侧上髁炎相关的该肌腱的基础解剖学信息。桡侧腕短伸肌腱的动脉血供高度一致。桡侧返动脉通过直接分支至肌腱的内侧和外侧缘，使整个近端肌腱血管化，在肌腱表面形成一个小血管网络。桡侧副动脉的后支提供了重要的血供，骨间返动脉提供了少量血供。肌腱的下表面似乎几乎无血管。这一观察结果表明，潜在的低血管区可能位于肌腱下表面，导致肌腱退变和部分撕裂，这可能是外侧上髁炎发病机制中的一个病因。需要进行额外的微血管研究来探究这一假说。
