Clinical Outcomes after Microdiscectomy for Recurrent Lumbar Disk Herniation: A Single-Center Study.

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: Revision discectomy is the principal procedure for recurrent lumbar disk herniation (RLDH). The clinical outcomes after this procedure are as good as or slightly poorer than those produced by primary discectomy. In this study, the clinical outcomes of patients treated with microsurgical discectomy for RLDH were analyzed. METHODS: We examined 179 patients undergoing lumbar microdiscectomy surgery for RLDH. The visual analogue scale (VAS), Prolo scoring system, and Oswestry Disability Index (ODI) were used for evaluating the improvement of symptoms and functional outcomes. CONCLUSION: Limited microsurgical discectomy could be considered as the main surgical method in patients with RLDH without overt instabilities.
