Abstract
Background: Recurrent lumbar disc herniation (RLDH) is a common complication following primary microdiscectomy. Notably, revision surgery for recurrent disc herniation typically warrants “aggressive discectomy (AD)” rather than microdiscectomy due to the marked changes in anatomy, including postoperative scar. Here, we prospectively evaluated clinical outcomes of 22 RLDH patients following secondary aggressive discectomy (AD).Methods: Records of 15 males and seven females averaging 41.7 years of age (range 21–60) who developed RLDH following primary microdiscectomy at the L4-5 (n = 12) and L5-S1 (n = 10) levels were studied. All patients underwent secondary AD for recurrent lesions (2014–2019). Multiple clinical parameters were assessed for these 22 patients. Outcomes were evaluated an average of 28.8 months postoperatively and included assessment of visual analog scales (VASs) and Japanese Orthopedic Association (JOA) Scores.Results: The VAS scores for back and radicular pain significantly improved, as did the JOA scores following surgery in all 22 patients after secondary AD.Conclusion: The authors concluded that secondary conventional revision discectomy (e.g., AD) effectively and safely managed RLDH.
