  • Data source: Minimally invasive surgery for lumbar disc herniation: a systematic review and meta-analysis, Kamper et al. Eur Spine J (2014) 23:1021–1043. The data has been used to read and collate the references and make meaningful groups based on timeline. These studies are the only studies which have been recently considered to appreciate the state of endoscopy at present.
