Minimally invasive transmuscular approach for the treatment of benign intradural extramedullary spinal cord tumours: Technical note and results

A minimal surgical approach using a tubular retractor permits an effective resection of intradural extramedullary tumours. This procedure may be a useful tool to decrease the risk of secondary spine instability and postoperative kyphosis, and could also be used for spinal junctions and in fragile patients.
