In this cadaveric study, we analysed digital images of dissected palms to define the location and length of superficial connections between the median and the ulnar nerves (Berrettini communicating branches). We found the connections present in 12 of 27 hands. We used a coordinate model to define their location relative to seven specified landmarks. The model revealed that the Berrettini communicating branches were positioned consistently, and we defined a high-risk zone in the palm that fully contained seven of the 12 connections, while others had minor projections outside the zone. We conclude that awareness of this high-risk zone in the palm can be of some help to reduce the risk of iatrogenic nerve injury, however, any operation in the palm must always be done with great care to visualize and protect any possible anatomically unusual structures.
在这项尸体研究中，我们分析了解剖手掌的数字图像，以确定正中神经和尺神经（贝雷蒂尼交通支）之间的浅表连接的位置和长度。我们发现 27 只手中有 12 只存在这些连接。我们使用坐标模型来定义它们相对于七个指定地标位置。该模型显示，贝雷蒂尼交通支的位置是一致的，我们在手掌上定义了一个高风险区域，该区域完全包含了 12 个连接中的 7 个，而其他连接只有轻微的突出。我们得出的结论是，对手掌上这个高风险区域的认识可以帮助减少医源性神经损伤的风险，但是，手掌上的任何手术都必须非常小心，以观察和保护任何可能存在的解剖结构异常。
