Percutaneous sacro-iliac screw osteosynthesis is considered to be standard of care for most posterior pelvic ring fractures. However, special situations require alternative strategies for sufficient stabilization. In these cases, stabilization can often be achieved using posterior instrumentation e.g. using SIPS-screws (spina-iliaca-posterior-superior screws). However, this often leads to implant-related aggravation of the sometimes already critical soft tissue conditions after pelvic trauma. S2-Ala-Ilium screws (S2AI screws) are a suitable alternative. The starting point lies medial of the posterior superior iliac spine below the iliac level. It is almost in line with a potential spinal instrumentation and therefore usually causes fewer soft tissue problems. Although this technique has been widely used in spinal surgery in recent years, its use in orthopaedic traumatology is largely unknown. The possibilities but also the limitations of this technique for the treatment of injuries to the pelvis are illustrated by this retrospective case series.
经皮骶髂螺钉固定被认为是大多数骨盆后环骨折的标准治疗方法。然而，特殊情况下需要替代策略来实现充分的稳定。在这些情况下，通常可以使用后路器械进行稳定，例如使用 SIPS 螺钉（骼后上螺钉）。然而，这往往会导致骨盆创伤后有时已经很严重的软组织状况因植入物而恶化。S2 髂骨螺钉（S2AI 螺钉）是一种合适的替代方法。起点位于髂嵴上方的后上髂嵴内侧，几乎与潜在的脊柱器械一致，因此通常会引起较少的软组织问题。尽管近年来这种技术在脊柱外科中得到了广泛应用，但在矫形创伤学中的应用却知之甚少。本回顾性病例系列说明了这种技术在治疗骨盆损伤中的可能性，但也存在局限性。
