Pelvic fracture in trauma patients can lead to hemodynamic instability. External fixation is a treatment capable of stabilizing these injuries in the context of damage control surgery. Supra-acetabular pin offers the greater biomechanical stability but requires the use of intraoperative fluoroscopy. The aim of this study was to analyze our results for an ultrasound-guided supra-acetabular pinning.
Cross-sectional study with cadaveric specimens. Ultrasound-guided pin placement assessed by fluoroscopy and dissection.
Fourteen ultrasound-guided supra-acetabular pins were placed in seven cadaveric specimens. Excellent placement in all cases, evaluated with radiological control. Good qualitative bone fixation after dissection. One femoral cutaneous nerve was not found during anatomic dissection and was assumed injured.
Ultrasound-guided supra-acetabular pin placement is a feasible and effective technique. Our study indicates that pin placement without intraoperative fluoroscopy is feasible without compromising the reliability of its placement.
创伤患者的骨盆骨折可导致血流动力学不稳定。外固定是一种能够在损伤控制手术中稳定这些损伤的治疗方法。髋臼上穿针提供了更大的生物力学稳定性，但需要术中使用荧光透视。本研究的目的是分析我们在超声引导下髋臼上穿针的结果。
对尸体标本进行横断面研究。通过荧光透视和解剖评估超声引导下的穿针放置。
在七个尸体标本中放置了十四根超声引导下的髋臼上穿针。经放射学检查评估，所有病例放置效果均极佳。解剖后骨固定质量良好。在解剖过程中未发现一条股皮神经，推测已受损。
超声引导下髋臼上穿针放置是一种可行且有效的技术。我们的研究表明，在不使用术中荧光透视的情况下进行穿针放置是可行的，且不影响其放置的可靠性。
