Background Context:
Incidental durotomy is the most frequent intraoperative complication reported in spinal literature. Multiple strategies have been suggested to manage it.
Methods:
A brief technical report.
Discussion:
The use of cottonoids is a recommended measure to avoid incidental durotomies during spinal surgeries; thus, ventral protection might be difficult to achieve. This "Chiripa technique" provides circumferential protection to the neurostructures, so that surgical procedures can be safely carried out.
Conclusion:
Taking into account the low costs and ease of execution, this can be a valuable tip that may widely extended in all cases where a circumferential dural protection is needed.
