新型手术体位，有效解决胫骨平台三柱骨折体位变换问题！
对累及三柱的胫骨平台骨折，通常需采用后内侧倒“L”型与前外侧切口联合治疗，通常采用漂浮体位，但漂浮体位存在两个问题：1.手术医生通常习惯性在仰卧位进行前外侧入路操作；2.漂浮体位不利于操作。有学者提出了一种新的体位，称之为“Out-in”体位，可有效解决上述问题。研究结果发表在2021.04 Injury期刊上。
ABSTRACT（摘要）
胫骨平台骨折的三柱分类以计算机断层扫描(CT)图像为基础，三柱骨折患者可采用漂浮位后内侧联合前外侧入路进行治疗。然而，在“漂浮体位”操作有一定的缺点。因此，我们为这些骨折建议了一个“Out-in”体位。患者仰卧在手术台上，健侧臀部垫高。对于后内侧入路，患肢应置于矩形透视台上，保持外展和外旋（out）；对于前外侧入路，患肢缩入手术床并保持中立位（in）。该位置已被证明对于简单操作和术中图像监控非常有效。此外，它突出了前后关节骨折复位的优势。
[Abstract: Three-column classification of tibial plateau fractures is based on computerized tomography (CT) images, and the patients with three-column fractures can be treated with posteromedial combined with anterolateral approach in the floating position. However, there are certain disadvantages to operating in a "floating position". Therefore, we proposed an "out-in" position for those fractures. The patient is placed in supine position on the operating table, and the healthy hip is elevated. For the posteromedial approach, the affected limb should be placed on a rectangular fluoroscopy table and kept in abduction and external rotation (out); for the anterolateral approach, the affected limb is retracted into the operating bed and kept in neutral position (in).This position has been shown to be highly effective for easy operation as well as intraoperative image monitoring. Furthermore, it highlights the advantage of anterior-posterior joint fracture reduction.]
