case_images: Additionally, critical stenosis of the spinal canal and intervertebral foramina was observed. (Figure 1) Prior to the surgery, a preoperative computed tomography (CT) scan was conducted, providing further information.
case_images: Preoperative computed tomography scan: (A) - axial plane at the level marked with the red line in the (B), (B) - midline sagittal plane.

case_images: Furthermore, the transverse dimension of the dural sac at the L4/L5 level was measured to be 15x9 [mm] (Figure 2).  
case_images: The 3D render of CT scan performed 24h after the surgery.

case_images: By consolidating these images, we aimed to provide a clearer visual representation of the precise positioning and alignment of the screws within the spinal structure (Figure 4). 
case_images: Postoperative radiological image of the lumbosacral section obtained 1 month after the surgery.

case_images: A digital radiograph obtained four weeks post-surgery revealed the accurate positioning of the screws, indicating successful alignment and stability. (Figure 5) At the four-month postoperative assessment, the patient's Oswestry Disability Index (ODI) improved to 34%, indicating a significant reduction in disability.
