▼This page is a tissue entry for the SELF Tissue Database.
It documents the structures, recommended materials, and related simulators associated with this tissue to support low-cost, reproducible surgical simulator development.

Dura mater (pachymeninx) is the tough outer layer of tissue that covers and protects the brain and spinal cord, and is one of the three layers that form the meninges.[1] It encloses the entire central nervous system and is anchored to the inner surface of the cranium and the vertebral cavity.[2] In a simulated lumbar laminectomy the dura is closed with fine sutures under the microscope (dural closure).

Materials

Material Visual Tactile Simulator Notes
Latex glove--Lumbar Laminectomy and Dural Closure Simulator (Bakhshi)Simulates the dura for dural-closure suturing under the microscope.[3]
  • Bone — the vertebral lamina removed to expose the dura in a laminectomy
  • The spinal cord and nerve roots — the neural tissue the dura protects and encloses
