经皮螺钉内固定联合骨盆复位是一种用于稳定骨盆后环骨折的手术技术。这是不稳定的骨盆后环损伤的标准手术治疗。这种治疗的主要目标是解剖复位和稳定固定。这已被证明可以减轻疼痛并改善患者的长期健康状况。该分析的目的是确定可能的螺钉长度和螺钉在 S1 和 S2 骶段的位置。分析了来自 Stryker 骨科建模和分析数据库的 697 个骨盆。确定 S1 和 S2 螺钉通道的尺寸，并在评估骶骨畸形后，选择正确的螺钉放置以确定手术治疗所需的螺钉长度。螺钉长度的测量值显示分析人群的高斯分布。S1 螺钉通道畸形骨盆的百分比为 31.3%，S2 螺钉通道为 8%。S1 的平均螺钉长度为 163.8 ± 16.2 mm，S2 的平均螺钉长度为 137.3 ± 9.5 mm。结果表明，S1/S2 轴不能用于每位患者的经骶骨螺钉置入。研究表明，68.7% 的 S1 位患者和 92% 的 S2 水平的患者存在骨内螺钉通道，其中预期的植入物可以完全植入骨内。结果表明，S1/S2 轴不能用于每位患者的经骶骨螺钉置入。研究表明，68.7% 的 S1 位患者和 92% 的 S2 水平的患者存在骨内螺钉通道，其中预期的植入物可以完全植入骨内。结果表明，S1/S2 轴不能用于每位患者的经骶骨螺钉置入。研究表明，68.7% 的 S1 位患者和 92% 的 S2 水平的患者存在骨内螺钉通道，其中预期的植入物可以完全植入骨内。

Analysis of trans-sacral corridors in stabilization of fractures of the pelvic ring

Percutaneous screw fixation combined with pelvic reduction is a surgical technique used to stabilize fractures of the posterior pelvic ring. This is the standard surgical treatment of unstable posterior pelvic ring injuries. The primary goal of this treatment is an anatomic reduction and stable fixation. This has been shown to reduce pain and improve the patients' long-term well-being. The aim of this analysis was to determine the possible screw lengths and the positioning of the screws in the S1 and S2 sacral segments. A population of 697 pelvises from the Stryker Orthopaedic Modeling and Analytics database were analyzed. The dimensions of the S1 and S2 screw corridors were determined and after assessing for sacral dysmorphism, the correct screw placement was chosen to determine the necessary screw length for surgical treatment. The measurements of the screw lengths show a Gaussian distribution for the analyzed population. The percentage of dysmorphic pelvises for the S1 screw corridor was 31.3% and for the S2 corridor 8%. Average screw length for S1 was 163.8 ± 16.2 mm and for the S2 137.3 ± 9.5 mm. The results show that the S1/S2 axis cannot be used for a trans-sacral screw placement in every patient. The study shows that intraosseous screw corridors are present in 68.7% of the patients in the S1 position and in 92% at the S2 level where an intended implant can be placed fully intraosseous.
