“…Following percutaneous laser discectomy, reductions in disc protrusions were observed by computed tomography (CT) [23], but not by MRI [24]. Similarly, no changes were observed on MRI following automated percutaneous lumbar discectomy [33]. One study did demonstrate moderate improvement in pain and function as well as reductions in disc protrusions on MRI after electrothermal disc decompression [34].…”

“…Other authors have commented on radiographic changes, but did not attempt to quantify these changes with any standardized technique [8,11,26]. Studies evaluating magnetic resonance imaging (MRI) changes following other forms of percutaneous discectomy have been published including chemonucleolysis [27][28][29][30][31]. Most showed small changes or no changes in disc morphology after treatment.…”

“…Postoperative MRI studies of lumbar disk herniation often show residual disk bulging.

Introduction This prospective case-control study aimed to establish the normal spectrum of early magnetic resonance imaging (MRI) findings in patients whose symptoms resolve after full endoscopic diskectomy (FED). We examined the changes in postoperative MRI findings and their relation to early clinical symptoms. Methods In total, 33 patients underwent FED under local anesthesia. Clinical assessments and MRI examinations were performed preoperatively and immediately (within 1 week) and late (at 3 and 12 months) postoperatively. Residual disk bulging after surgery was classified into four grades compared with preoperative MRI findings: none (grade A), <25% (grade B), 25–75% (grade C), and >75% (grade D). Results MRI at postoperative week 1 showed grade B residual disk bulging in 9 patients, grade C residual disk bulging in 8 patients, and grade D residual disk bulging in 16 patients. Improvement was seen at postoperative month 3 (grade A in 18 patients, grade B in 10 patients, and grade C in 5 patients) and at postoperative month 12 (grade A in 29 patients, grade B in 3 patients, and grade C in 1 patient). Visual analog scale scores and the Japanese Orthopaedic Association scores showed significant differences at 1 week, 3 months, and 12 months after surgery. Conclusion Postoperative MRI findings within 1 week of FED showed grade C or D residual disk material in 24 of 33 patients (73%). Clinical symptoms improved in the early postoperative period, even though residual disk bulging was present. Persisting residual bulging in the early stage following surgery may not correlate with clinical symptoms.
