Quantitative Evaluation of the Trauma of CT Navigation PELD and OD in the Treatment of HLDH: A Randomized, Controlled Study.

BACKGROUND

More evidence is required to support that computerized tomography navigation percutaneous spinal endoscopy in the treatment of highly migrated lumbar disc herniation is a more minimally invasive surgery than open discectomy .

OBJECTIVE

To quantitatively evaluate the efficacy and minimal invasiveness of computerized tomography navigation percutaneous spinal endoscopy and open discectomy in highly migrated lumbar disc herniation.

STUDY DESIGN

A prospective randomized study.

SETTING

First Affiliated Hospital of Gannan Medical College.

METHODS

From August 2016 to February 2020, 68 patients with highly migrated lumbar disc herniation had undergone discectomy. Thirty-five of them randomly received computerized tomography (CT) navigation percutaneous spinal endoscopy at the pain department (CT navigation percutaneous spinal endoscopy group), and 33 patients received open discectomy at the orthopedics department (open discectomy group). The Visual Analog Scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and modified MacNab criteria were applied to evaluate the clinical situations pre- and post-operation. The serum concentrations of IL-6, TNF-alpha, creatine phosphokina (CPK), and C-reactive protein (CRP) in the 2 groups were quantitatively measured.

RESULTS

The postoperative VAS scores of the back and lower extremity were lower than those pre-operation in both groups, while the VAS score of back pain in the open discectomy group was significantly higher than that in the CT navigation percutaneous spinal endoscopy group at one week post-operation (P < 0.01). The postoperative JOA scores were significantly higher than those pre-operation in both groups. The serum concentrations of IL-6, TNF-alpha, CPK, and CRP in the open discectomy group were higher than those in the computerized tomography navigation percutaneous spinal endoscopy group postoperatively (P < 0.01).

LIMITATIONS

This is a single-center randomized study and with the limitation of the sample size.

CONCLUSION

CT navigation percutaneous spinal endoscopy is a more minimally invasive surgery than open discectomy.Certificate number for the medical institution conducting the clinical trials for humans in China: 934.
