Case report of the Bendini usage at two stage surgical treatment of adult spinal deformity

Abstract

Introduction: At surgical treatment of adult spinal deformity, some cases are difficult to release bony fused facet joint and vertebral discs by using only LIF technique. Cage insertion in such rigid cases sometimes resulted in vertebra fractures and endplate damages.

Therefore, in such cases, after the release of the facet joint and gain the movement between the vertebras, we performed LIF technique and correct the deformity. But this method takes long operation time and is highly invasive. So at most cases two-stage surgery is planned.

Case Report: At two-stage surgery for rigid facet fusion cases, we perform pedicle screw insertion and facet joint release in the first stage, then install the rods while the deformity remains. At second stage, remove the rods in the lateral position, perform LIF, and perform the correction of the deformity again from the posterior side. By doing so, even during the waiting period for the second stage surgery, the patient can move freely without wearing a corset. However, if the rod is installed while the deformation remains, it takes long time and is difficult to insert the rod. So, we report usefulness of Bendini use for making rod curve even if the deformation remained in the first stage.

Conclusion: We reported the usefulness of Bendini use for rod formation in the first stage of two-stage adult spinal deformity correction surgery while the deformation remains.
