The microvascular anatomy of the triangular fibrocartilage complex was investigated in 10 cadaver specimens by histology and tissue clearing (Spalteholz) techniques. It was found that the triangular fibrocartilage of the wrist is supplied by small vessels that penetrate the triangular fibrocartilage complex in a radial fashion from the palmar, ulnar, and dorsal attachments of the joint capsule and supply the peripheral 10% to 40%. The inner (horizontal) portion is avascular, and no vessels cross the radial attachment of the triangular fibrocartilage complex. The results of this study suggest that tears in the periphery of the triangular fibrocartilage complex may have sufficient blood supply to mount a reparative response and, in theory, can be repaired. However, tears that occur in the center and along the radial attachment do not have immediate access to a blood supply and are not likely to heal.
采用组织学和组织透明（斯帕尔托霍尔茨）技术，对10例尸体标本的三角纤维软骨复合体的微血管解剖结构进行了研究。结果发现，腕部三角纤维软骨由小血管供血，这些小血管从关节囊的掌侧、尺侧和背侧附着处呈放射状穿透三角纤维软骨复合体，供应其周边10%至40%的区域。内侧（水平）部分无血管，且没有血管穿过三角纤维软骨复合体的桡侧附着处。本研究结果表明，三角纤维软骨复合体周边的撕裂可能有足够的血液供应以引发修复反应，理论上可以修复。然而，发生在中央和沿桡侧附着处的撕裂无法立即获得血液供应，不太可能愈合。
