腕部 flexion 褶皱与掌侧桡腕关节之间的关系：一项尸体研究。 （注：这里“flexion”准确意思是“屈曲” ，结合语境，推测原文中腕部flexion creases 可能是指腕部屈曲褶皱，但因不清楚确切专业术语，暂按原文翻译）

BACKGROUND
Surgical approaches to the volar radiocarpal joint have historically entailed wide exposure, possibly contributing to poor wound healing and wrist denervation. To avoid wound complications and wrist denervation, minimally invasive and percutaneous approaches to the volar radiocarpal joint have been proposed. To help guide these minimally invasive or percutaneous approaches to the joint, we sought to characterize the relationship between the volar wrist flexion creases and the volar radiocarpal joint. We propose that the wrist flexion creases will be a reliable method for localizing the joint.
METHODS
Ten cadaveric upper-extremity specimens consisting of fingertip to mid forearm were obtained. Measurements from the proximal and distal wrist flexion creases were taken via fluoroscopy and gross dissection.
RESULTS
The wrist flexion creases were located distal to the volar radiocarpal joint in all specimens. The volar radiocarpal joint was located 7 and 16 mm proximal to the proximal and distal wrist flexion creases, respectively. The radiographic anatomy correlated well with the underlying deep anatomy.
CONCLUSIONS
The wrist flexion creases can serve as a reliable superficial landmark for the identification of the volar radiocarpal joint. These landmarks aid clinicians in performing or interpreting a physical examination or in performing minimally invasive or percutaneous approaches to the volar radiocarpal joint.
背景
从历史上看，掌侧桡腕关节的手术入路需要广泛暴露，这可能导致伤口愈合不良和腕部神经支配丧失。为避免伤口并发症和腕部神经支配丧失，有人提出了掌侧桡腕关节的微创和经皮入路。为帮助指导这些关节的微创或经皮入路，我们试图描述腕掌侧屈曲纹与掌侧桡腕关节之间的关系。我们认为腕部屈曲纹将是定位该关节的可靠方法。
方法
获取了10个从指尖到前臂中部的尸体上肢标本。通过荧光透视和大体解剖测量腕部近端和远端屈曲纹。
结果
在所有标本中，腕部屈曲纹均位于掌侧桡腕关节的远侧。掌侧桡腕关节分别位于腕部近端和远端屈曲纹近端7毫米和16毫米处。影像学解剖与深层解剖结构相关性良好。
结论
腕部屈曲纹可作为识别掌侧桡腕关节的可靠体表标志。这些标志有助于临床医生进行或解释体格检查，或对掌侧桡腕关节进行微创或经皮入路操作。
