Cement augmentation of sacroiliac (SI) screws in the posterior pelvic ring has been shown to provide greater biomechanical stability in cadaveric studies. Pelvic ring fractures are relatively rare compared to the total number of fractures. Nevertheless, the 1‑year mortality rate of up to 27% is very high, especially for geriatric pelvic ring fractures and is also largely associated with reduced mobility due to the fracture. The primary goal of treatment is therefore the restoration of patient mobility. This requires the achievement of sufficient stability of the pelvic ring. As osteoporosis is often a causative factor for the pelvic ring fracture, a more stable anchoring of the implants in the osteoporotic bone can be achieved by cement augmentation. This article presents the possibilities of cement augmentation of the pelvic ring and describes the technique of cement-augmented SI screws.
在尸体研究中，骶髂（SI）螺钉的骨水泥强化已被证明能为骨盆后环提供更大的生物力学稳定性。与骨折总数相比，骨盆环骨折相对少见。然而，高达27%的1年死亡率非常高，尤其是老年骨盆环骨折，并且在很大程度上也与骨折导致的活动能力下降有关。因此，治疗的主要目标是恢复患者的活动能力。这需要实现骨盆环足够的稳定性。由于骨质疏松症往往是骨盆环骨折的一个致病因素，通过骨水泥强化可以在骨质疏松的骨骼中实现植入物更稳定的锚固。本文介绍了骨盆环骨水泥强化的可能性，并描述了骨水泥强化SI螺钉的技术。
