摘要
背景尺骨隧道综合征（UTS）是一种罕见的周围神经病，与尺神经（UN）远端在穿过腕部纤维骨性尺骨隧道（同名的古永氏管）的过程中被卡住有关。尺骨隧道内的尺神经很容易受到损伤或压迫而导致 UTS。因此，了解尺骨隧道内 UN 分支模式的解剖变化具有重要的临床意义。UTS的特征是感觉障碍和肌肉无力，指尖外侧感觉受损，手部固有肌肉抓握无力。本研究的目的是在选定的南非尸体群体中检查手掌中 UN 的解剖变异。方法在 81 具尸体（n = 162）中检查了 UN 分支模式的变异，并根据 Murata 等人（2004 年）的分类系统进行了描述[10]。沟通的分支根据以往文献中的描述进行分类。尺骨隧道的长度从梨状骨水平测量到锤骨钩水平。结果发现分支模式为 1 型（52.9%）、2 型（34%）、3 型（2.7%）、4 型（6.5%）和 5 型（3.9%）。结论外科医生必须意识到这些解剖变异，因为它们可能会在治疗UTS的手术过程中导致误诊和并发症。本文章由计算机程序翻译，如有差异，请以英文原文为准。
Variations of the ulnar nerve within the ulnar tunnel and palm in a select South African population
Background
Ulnar tunnel syndrome (UTS) is a rare peripheral neuropathy associated with the entrapment of the distal portion of the ulnar nerve (UN) in its course through the fibro-osseous ulnar tunnel (eponymously known as Guyon's canal) at the wrist. The UN within the ulnar tunnel is prone to injury or compression resulting in an UTS. Therefore, it is of clinical importance to know the anatomical variations in the branching pattern of the UN within the ulnar tunnel. UTS is characterised by sensory deficits and muscular weakness, impaired sensation of the volar fingertips, and weakness in grasping with intrinsic hand muscles. This study aimed to examine the anatomical variations of the UN in the palm of the hand within a select South African cadaveric population.
Methods
The variations in the branching patterns of the UN were examined in 81 cadavers (n = 162) and described according to the classification system of Murata et al. (2004) [10]. Communicating branches were classified according to their description in previous literature. The length of the ulnar tunnel was measured from the level of the pisiform bone to the level of the hook of hamate.
Results
The branching pattern was found as Type 1 (52.9 %), Type 2 (34 %), Type 3 (2.7), Type 4 (6.5 %), Type 5 (3.9 %). Berrettini, Riche-Cannieu and Kaplan anastomoses were found in 51.6 %, 2 % and 3.3 % of specimens, respectively.
Conclusion
It is important for surgeons to be aware of these anatomical variations as they may lead to misdiagnosis and complications during surgical procedures during the treatment of UTS.

期刊介绍：
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
