Surgical treatment of sacral fractures following lumbosacral arthrodesis: Case report and literature review

Figure 1 Magnetic resonance imaging of the spine found central lumbar spinal stenosis at L5/S1 level and L4-S1 foraminal narrowing.

Figure 2 A computed tomography scan revealed a horizontal fracture at the S1/S2 level with S2 being totally displaced.

Figure 3 The interspinous process of the sacrum was totally displaced. It moved backward and cranially onto the back of the instruments. To reduce the fracture, we used a spreader to distract the spinal processes of S1 and L4, which was effective. After the distraction, the distance between the spinal processes of the S1 and L4 increased significantly.

Figure 4 Sacral fracture found on the 5^th day after surgery. Two weeks after the index operation, the fusion construct was extended to the iliac wings using iliac screws.
