A systematic review of MIS and open decompression surgery for spinal metastases in the last two decades.

Objective: The primary intention of this review being to produce an updated systematic review of the literature on published outcomes of decompressive surgery for metastatic spinal disease including metastatic spinal cord compression, using techniques of MIS and open decompressive surgery.

Methods: The authors conducted database searches of OVID MEDLINE and EMBASE identifying those studies that reported clinical outcomes, surgical techniques used along with associated complications when decompressive surgery was employed for metastatic spinal tumors. Both retrospective and prospective studies were analysed.
