在30例成人尸体的手上,对手指神经血管束进行了应用解剖学研究。手指掌侧的神经血管束位置恒定,神经横径和血管外径在掌指关节平面和第一指间关节平面间均相差约0.3mm。食指、中指和环指指背第一指节远侧半至指尖大部由指固有神经背侧支分布。认为,手指神经和血管的主干横径变化不大,有利于修复。在手指部作手术切口时,应注意保护指固有神经背侧支。 Anatomical study of finger neurovascular bundles was performed on the hands of 30 adult cadavers. The neurovascular bundle at the palmar side of the finger was located at a constant position with a difference of about 0.3 mm between the transverse diameter of the nerve and the diameter of the vessel outside the metacarpophalangeal plane and the first interphalangeal plane. The index finger, middle finger and ring finger refers to the back of the first knuckle distal to semi-fingertips by the majority of the dorsal branch of the nerves refers to the distribution. That the main axis of finger nerves and blood vessels little change in diameter, is conducive to repair. In the finger for surgical incision, care should be taken to protect the dorsal nerve branch.
