AO Spine C3 sacral fractures are defined by separation of the spine including S1 from the pelvic ring and are usually result of a high-energy injury. Besides their high biomechanical instability and high rate of associated neurological impairment, these fractures are often extremely difficult to reduce due to severe bony impaction and dislocation. Additional difficulties in management of these fractures arise from only a thin-layer of soft-tissue coverage overlying the injured area.

AO 脊柱 C3 骶骨骨折的开放后路复位和稳定术

AO 脊柱 C3 骶骨骨折定义为包括 S1 在内的脊柱与骨盆环分离，通常是高能量损伤的结果。除了高度的生物力学不稳定性和相关神经损伤的高发生率外，这些骨折通常由于严重的骨嵌塞和脱位而极难复位。处理这些骨折的其他困难来自仅覆盖受伤区域的薄层软组织。
