Placement of a Kickstand Rod in Adult Spinal Deformity Surgery: A Simple 8-Step Process With Intraoperative Images and Video.

BACKGROUND AND OBJECTIVES: In adult spinal deformity (ASD) surgery, operative correction of coronal malalignment remains a challenging surgical task. Given the proven effectiveness and longevity of the kickstand rod (KSR) technique and its powerful ability to correct coronal malalignment, this technique is an important tool to have available. Therefore, we sought to provide a simple 8-step description of the KSR technique using intraoperative images and video in a patient undergoing combined sagittal and coronal malalignment correction.

METHODS: A 68-year-old female with a previous history of T11-S1 posterior spinal fusion presented with mid thoracic back pain, leg paresthesias, and a right-leaning posture. The patient underwent a T4-pelvis extension of fusion, T8-11 posterior column osteotomies, and placement of a right-sided KSR to address her coronal malalignment.

RESULTS: The KSR technique is summarized in the following steps: (1) place kickstand screw, (2) place contralateral main rod and tighten all set plugs, (3) place ipsilateral main rod and keep rod long distally, (4) place a domino in the lower/mid thoracic area, (5) place the KSR and leave the rod long proximally, (6) tighten the ipsilateral main rod above the domino, (7) loosen the ipsilateral main rod below the domino, and (8) place a rod gripper below the domino and distract. Postoperatively, the coronal vertical axis improved from 4.8 to 0.6 cm, and the sagittal vertical axis improved from 9.5 to 3.9 cm.

CONCLUSION: The current case report provides a simple 8-step description of the KSR technique to improve coronal malalignment accompanied by intraoperative images and video.
