In a lumbar laminectomy, if the dura is punctured, what type of suture should be used to repair it?

In the context of repairing a punctured dura during a lumbar laminectomy, the use of Prolene, a non-absorbable synthetic suture material, is particularly advantageous for several reasons. Prolene is known for its strength and pliability, providing a secure closure that minimizes the risk of leakage of cerebrospinal fluid (CSF). Since dural tears can potentially lead to complications such as pseudomeningocele or CSF fistulae, a durable and reliable suture material is crucial.

Prolene's non-reactive nature also contributes to reduced tissue irritation. This is important in the delicate environment of the dura mater, where excessive inflammation can impede healing and recovery. The choice of a non-absorbable suture allows for long-term stability at the repair site, which is vital when considering the dynamic movements of the lumbar spine and the stresses that may be applied post-operatively.

In contrast, other materials like silk, Vicryl, and catgut do not offer the same balance of strength, durability, and non-reactivity. Silk, while strong, is absorbable in part but not to the same extent as Vicryl and can lead to foreign body reactions over time. Vicryl is absorbable, which may not be
