Summary
Intraoperative ultrasound aids spinal cord assessment during pedicle subtraction osteotomy (PSO). This imaging tool helps surgeons ensure safe reduction and neural element decompression, minimizing risks associated with PSO surgery.
Area of Science:
- Spine surgery
- Neurosurgery
- Medical imaging
Background:
- Pedicle subtraction osteotomy (PSO) corrects sagittal alignment but risks neurologic injury.
- Neural element compression during PSO reduction can cause deficits.
Observation:
- Intraoperative ultrasound (IOUS) was used in 3 thoracic PSO cases.
- The study evaluated IOUS feasibility, findings, and utility.
Findings:
- IOUS provides real-time visualization of spinal cord morphology before and after PSO reduction.
- It guides surgical decisions on sagittal correction and confirms ventral decompression.
- IOUS is useful for assessing thecal sac kinking and underlying spinal cord status.
Implications:
- Intraoperative ultrasound is a reliable tool that integrates well into PSO procedures.
- It offers a visual supplement to standard neuromonitoring for safe PSO.
- This modality can enhance surgical safety and improve patient outcomes in PSO.
