Pelvic ring injuries form part of the spectrum of polytraumaandmust be considered a potentially lethal injury with mortality rates of 10-20%. The stabilization of the unstable pelvic ring in acute resuscitation of multiply injured patients is now conventional wisdom.We aimed: (1) to design a new iliosacral (IS) screw, (2) to prove the clinical advantages of this new implant, and (3) to work out the optimal surgical strategy using this implant. Taking the demands of the above mentioned data into account, a 10 mm 2.8 mm-cannulated iliosacral screw seemed to be optimal for the special requirements. Before industrial production, finite element analysis (FEA) was performed to find out whether these screws would be enough to stabilize the posterior pelvic ring alone or not. Clinical experience led to the modification of the set of instruments, which finally yielded handy tools and implants. Building further on the surgical skills and experiences gained (by the surgeons and the O.R. personnel), we increased our capacity to perform more and more immediate pelvic fixations. Emergency pelvic stabilizationswere performed in patientswith pelvic injuries who had hemodynamic instability, despite immediate shockmanagement during the diagnostic period. During thelast eleven years, 244 patientswith Tile B3 and Cpelvic injuries have been stabilized with 10-mm diameter cannulated IS screws percutaneously posteriorly. Fortyeight hemodynamically unstable patientswere stabilized in the first 2 h with iliosacral screw fixation. The percutaneous pelvic ring stabilization with 10-mm cannulated screws provedstrongenoughin bothersome casesaswell.
骨盆环损伤是多发伤的一部分,必须被视为一种潜在的致命伤,死亡率为10%-20%。在对多发伤患者进行急性复苏时,稳定不稳定的骨盆环现已成为共识。我们的目标是:(1)设计一种新型髂骶(IS)螺钉,(2)证明这种新型植入物的临床优势,(3)制定使用这种植入物的最佳手术策略。考虑到上述数据的要求,一种10毫米×2.8毫米的空心髂骶螺钉似乎最符合特殊需求。在进行工业化生产之前,进行了有限元分析(FEA),以确定这些螺钉是否足以单独稳定骨盆后环。临床经验促使对器械套装进行了改进,最终产生了便于使用的工具和植入物。基于(外科医生和手术室工作人员)所获得的手术技能和经验,我们进行越来越多即时骨盆固定的能力得到了提高。对于在诊断期间尽管进行了即时休克处理但仍存在血流动力学不稳定的骨盆损伤患者,进行了急诊骨盆稳定术。在过去的十一年中,244例Tile B3和C型骨盆损伤患者通过经皮后路使用直径10毫米的空心IS螺钉实现了稳定。48例血流动力学不稳定的患者在最初2小时内通过髂骶螺钉固定实现了稳定。在棘手的病例中,经皮使用10毫米空心螺钉进行骨盆环稳定也被证明足够有效。
