Zhang B, et al. - Experts compared the transforaminal endoscopic discectomy (TED) with open microdiscectomy for lumbar discherniation (LDH). They performed a systematic literature search using the PubMed, EMBASE, and Cochrane Library databases for trials written in English. Findings suggested the superiority of transforaminal endoscopic discectomy to open microdiscectomy in the length of hospital stay. Nonetheless, in treating LDH, no differences in leg pain, functional recovery, and incidence of complications between TED and MD were seen.
