Arachnoid-trabeculae tenting as a self-retaining retractor in resecting ventrally located spinal meningioma - Technical note

Abstract

Tenting of the arachnoid with intact trabeculae to facilitate and maintain rotation of the cord during the resection of ventrally or ventrolaterally located spinal meningiomas is proposed. The arachnoid-trabeculae tenting acts as a self-retaining retractor, and prevents overlapping of the cord onto the tumor due to gravity.
