The extrinsic vasculature of the ulnar nerve as it relates to the treatment of cubital tunnel syndrome has not previously been described in detail. For a study of the anatomy, 18 fresh-frozen cadaver upper limbs were dissected after intra-arterial injection of latex. Two major pedicles were present in all 18 specimens--the superior ulnar collateral artery proximally and the posterior ulnar recurrent artery distally. A single minor pedicle, the inferior ulnar collateral artery, was present in 5 of 18 specimens. Total vessel length as well as distance to the medial epicondyle for the extrinsic arteries was measured. On the basis of these anatomic dissections, it is suggested that the extrinsic vascular supply can be preserved during anterior transposition of the ulnar nerve, even after extensive mobilization of the nerve.
尺神经的外在血管系统与肘管综合征的治疗相关，此前尚未有详细描述。为进行解剖学研究，在动脉内注射乳胶后，对18具新鲜冷冻尸体的上肢进行了解剖。所有18个标本中均存在两个主要的血管蒂——近端为尺侧上副动脉，远端为尺侧后返动脉。18个标本中有5个存在单个较小的血管蒂，即尺侧下副动脉。测量了外在动脉的总血管长度以及与内上髁的距离。基于这些解剖学研究结果，表明即使在尺神经广泛游离后，在尺神经前移过程中也可保留其外在血管供应。
