Treatment of lumbar disc herniation with robot combined with unilateral biportal endoscopic technology:A case report

BACKGROUND This reported procedure combines the orthopedic surgical robot with the unilateral biportal endoscopy-lumbar interbody fusion(UBE-LIF),utilizing the UBE's wide viewing field and operating space to perform minimally invasive decompressive fusion of the lesioned segment,and the orthopedic surgical robot's intelligence and precision to perform percutaneous pedicle screw placement.The advancement of this procedure lies in the superposition of advantages and offsetting disadvantages of the two new technologies,and the maximum effect of treatment is achieved with maximum minimization of invasiveness and precision under the monitoring of imaging instruments to maximize the benefit of patients,and this review reports a case of multiple-segment lumbar decompression and fusion surgery for lumbar disc herniation via robot-assisted UBE for reference.CASE SUMMARY A 44-year-old patient presented to our hospital.Combining various clinical data,we diagnosed the patient with lumbar disc herniation with radiculopathy,lumbar spondylolisthesis,and lumbar spinal stenosis.We developed a surgical plan of"UBE decompression+UBE-LIF+orthopedic surgery robot-assisted percutaneous pedicle screw implantation for internal fixation".The results were satisfactory.CONCLUSION We present an extremely rare case of multiple-segment lumbar decompression and fusion surgery for lumbar disc herniation via robot-assisted UBE and achieved good results.Therefore,the technique is worthy of clinical promotion.

Clinical Study on Treatment of Type II/III Lumbar Brucellar Spondylitis by Unilateral Biportal Endoscopy

Objective: Explore the feasibility and clinical efficacy of using unilateral biportal endoscopy for the treatment of Type II/III lumbar brucellar spondylitis. Methods: A retrospective study of the clinical data of 20 patients with Type II/III lumbar brucellar spondylitis admitted to the First Affiliated Hospital of Hebei North University from January 2020 to May 2022, including 15 males and 5 females, aged 41 - 60 years old, average age (48.11 ± 7.28) years old. After admission, the patient can isolate brucella through metagenomic Next-Generation Sequencing (mNGS), meeting the tertiary diagnostic criteria. Preoperative conventional drug treatment, unilateral biportal endoscopic minimally invasive surgery was performed when nutrition was improved, perioperative control of various indexes was stable, and erythrocyte sedimentation was declining. It was completed under an endoscope. The lesion was cleared, spinal nerve compression was relieved, interbody fusion was performed, and the spine was fixed by a percutaneous pedicle screw. Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP), Visual Analogue Scale (VAS), Japanese Orthopedic Association (JOA) score and Oswestry Disability Index (ODI) were analyzed at 1 month, 3 months, 6 months and the last follow-up. At the final follow-up of all patients, the clinical efficacy criteria and the Bridwell grading criteria were used to evaluate the recovery and intervertebral bone graft fusion, respectively. Results: All patients’ lower back and leg pain was relieved the next day after surgery. At a follow-up of one month after surgery, both systemic and local symptoms significantly improved. At the last follow-up, clinical symptoms disappeared and there was no tenderness or percussion pain in the local area. With the passage of time, 1 month, 3 months, 6 months after the operation, and the last follow-up are all evaluation indicators compared with those before the operation. No matter VAS, JOA, ODI score, or ESR, CRP is significantly improved compared with preoperative (P All 20 cases in this group reached the BS clinical cure standard, and the excellent rate of intervertebral bone graft fusion was 95%. Conclusion: On the basis of .
