Revised understanding of iatrogenic lumbosacral nerve bowstringing disease: a case report and literature review

Excessive expansion of the intervertebral space can lead to sustained static traction on the nerve roots. The appropriate fusion device height should be determined through a stepwise expansion test to avoid increased axial tension on the nerves. Additionally, technical operational details can independently induce bowstring syndrome, and stepwise tension assessment is crucial for preventing traction-related nerve damage.
