Benign lesions of the spine include benign tumors and tumor-like lesions of the spine, which usually occur in the thoracic and lumbar vertebrae. The incidence rate is low, accounting for about 1% of primary bone tumors. Few cases of endoscopic treatment of benign spinal lesions have been reported in the literature. Here, we introduce a new surgical technique using full endoscopy and allogeneic bone grafting to treat benign spinal lesions. All patients in this study successfully underwent the operation, and their pain was significantly relieved postoperatively. The patient VAS scores decreased from 3.07 ± 0.70 preoperatively to 0.33 ± 0.49 at the last follow-up visit (p < 0.05). The mean total blood loss (including drainage blood) was 16.67 ± 6.98 mL. The mean operative time was 63.33 ± 7.23 min. No patients developed numbness in the corresponding segmental distribution after surgery, none of the patients had serious postoperative complications, and none had focal recurrence during follow-up requiring reoperation. Patients reported symptom relief throughout the whole follow-up period. We believe that endoscopic surgery preserves the ligaments and soft tissues around the vertebral body, and that this technique is feasible with minimal trauma, rapid recovery, and good outcomes at short-term follow-up. This minimally invasive treatment modality offers a new option for the treatment of patients with benign spinal lesions.

Purpose: To evaluate the application value of percutaneous endoscopic spinal surgery for young patients with discogenic low back pain (DLBP) and to judge its clinical efficacy. Methods: We retrospectively analyzed young patients with single-segment discogenic lumbago from July 2018 to June 2020 in our department who underwent percutaneous endoscopic surgery according to the inclusion and exclusion criteria. We finally enrolled 20 patients. The follow-up time was 6– 30 months. In all patients, we recorded the visual analog scale (VAS) score for waist pain and the Oswestry Disability Index (ODI) preoperatively, immediately postoperatively and at the last follow-up. We used the modified MacNab criteria to assess the curative effect at the last follow-up. Results: All 20 patients underwent successful operations without complications. No recurrence was observed during follow-up. The VAS score of low back pain was 5.05± 1.19 points before surgery, 1.50± 051 points immediately after surgery, and 1.10± 0.72 points at the last follow-up (P < 0.05 preoperative vs both postoperative). At the last follow-up, the VAS scores of all 20 patients were ≤ 2, and 4 patients had no pain. The ODI was 46.66± 7.03% before surgery, 9.78± 4.05% immediately after surgery, and 4.11± 3.18% at the last (P < 0.05, preoperative vs both postoperative). According to the evaluation under the modified MacNab standard, the good–excellent rate of clinical efficacy at the last follow-up was 95%. Conclusion: Percutaneous endoscopic spinal surgery can significantly improve the symptoms and dysfunction of young patients with DLBP and has little effect on the biomechanical stability of the lumbar spine. This surgery has great clinical application value.
