Abstract OBJECTIVE: It remains unknown whether aggressive disc removal with curettage or limited removal of disc fragment alone with little disc invasion provides a better outcome for the treatment of lumbar disc herniation with radiculopathy. We reviewed the literature to determine whether outcomes reported after limited discectomy (LD) differed from those reported after aggressive discectomy (AD) with regard to long-term back pain or recurrent disc herniation. METHODS: A systematic MEDLINE search was performed to identify all studies published between 1980 and 2007 reporting outcomes after AD or LD for a herniated lumbar disc with radiculopathy. The incidence of short- and long-term recurrent back or leg pain and recurrent disc herniation was assessed from each reported LD or AD cohort and the cumulative incidence compared. RESULTS: Fifty-four studies (60 discectomy cohorts) met the inclusion criteria, reporting the outcomes of 13 359 patients after lumbar discectomy (LD, 6135 patients; AD, 7224 patients). The reported incidence of short-term recurrent back or leg pain was similar after LD (mean, 14.5\%; range, 7-16\%) and AD (mean, 14.1\%; range, 6-43\%) (P < 0.01). However, more than 2 years after surgery, the reported incidence of recurrent back or leg pain was 2.5-fold less after LD (mean, 11.6\%; range, 7-16\%) compared with AD (mean, 27.8\%; range, 19-37\%) (P < 0.0001). The reported incidence of recurrent disc herniation after LD (mean, 7\%; range, 2-18\%) was greater than that reported after AD (mean, 3.5\%; range, 0-9.5\%) (P < 0.0001). CONCLUSION: Review of the literature demonstrates a greater reported incidence of long-term recurrent back and leg pain after AD but a greater reported incidence of recurrent disc herniation after LD. Prospective, randomized trials are needed to firmly assess this possible difference. This article was published in Neurosurgery and referenced in Journal of Pain & Relief
