Abstract

Abstract:

Background

The unilateral biportal endoscopy (UBE) technique is a new minimally invasive spinal surgical technique, which has been used to treat various degenerative spinal diseases in recent years. However, there is no literature reporting this technique for the treatment of lumbar brucellosis spondylitis (LBS) .

Objective

To investigate the effectiveness and feasibility of the UBE technique in the treatment of LBS.

Methods

This study selected 13 patients with LBS who received the UBE treatment in the Department of Orthopaedics, the First Affiliated Hospital of Xinjiang Medical University from January 2020 to June 2021. The operative duration, the estimated blood loss and complications were recorded. Clinical outcomes of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), the visual analog scale (VAS) scores of low back and leg, Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI), American Spinal Injury Association (ASIA) neurological classification, and lordotic angle were analyzed. All patients were assessed using the modified Macnab criteria at 1-year follow-up after operation. The intervertebral bone graft fusion was evaluated using Bridwell grading criteria.

Results

The operation time was 145-210 minutes, with an average of (177.31±19.54) minutes. The estimated blood loss was 120-290 ml, with an average of (176.15±43.79) ml. There were 2 complications, with an incidence rate of 2/13. ESR and CRP levels returned to normal at the 3-month follow-up. The VAS scores of low back and leg, JOA score, and ODI were significantly improved compared to those before operation at each postoperative follow-up time point, and the differences were statistically significant (P<0.05). The modified Macnab criteria evaluation at 1-year follow-up showed that the outcomes were excellent in 10 cases, good in 2 cases, fair in 1 case, and no patient showed poor outcomes, with a rate of excellent and good was 12/13. The lordotic angle decreased from preparation (47.18°±6.88°) to predischarge (40.83°±6.71°), and there was no significant loss of angle at 1-year follow-up after operation. Bony fusion was obtained in all patients at 1-year follow-up after operation, of which 12 cases were grade Ⅰ and 1 case was grade Ⅱ, with a fusion rate of 12/13.

Conclusion

UBE technique is an effective, safe and feasible surgical procedure for treating LBS.

摘要：

背景

单侧双通道内镜（UBE）技术是一种新兴的脊柱微创手术技术，近年来已被用于治疗各种退行性脊柱疾病。然而，尚未有相关文献报道该技术治疗腰椎布鲁菌病脊柱炎（LBS）。

目的

探讨UBE技术治疗LBS的有效性及可行性。

方法

选取2020年1月至2021年6月新疆医科大学第一附属医院骨科收治的LBS接受UBE技术治疗的患者13例。记录手术时间、可估计失血量及并发症发生情况。分析红细胞沉降率（ESR）、C反应蛋白（CRP）、腰背部和腿部视觉模拟评分（VAS）、日本骨科协会（JOA）评分、Oswestry残疾指数（ODI）、美国脊髓损伤协会（ASIA）神经系统分型和前凸角等临床结果。所有患者术后1年随访时采用改良Macnab标准进行评估。采用Bridwell分级标准评估椎间植骨融合情况。

结果

13例LBS患者手术时间145~210 min，平均（177.31±19.54）min；可估计失血量120~290 ml，平均（176.15±43.79）ml；共发生2例并发症，发生率为2/13。术后3个月随访，ESR和CRP水平恢复正常。术后各随访时间点腰背部和腿部VAS、JOA评分及ODI均较术前明显改善，差异有统计学意义（P<0.05）。术后1年随访时改良Macnab标准评价示：优10例、良2例、可1例、差0例，优良率为12/13。前凸角由术前（47.18°±6.88°）降至出院前（40.83°±6.71°），术后1年随访时无明显角度丢失。所有患者术后1年随访时获得骨性融合，其中12例融合等级为Ⅰ级、1例为Ⅱ级，融合率为12/13。

结论

UBE技术是治疗LBS的一种有效、安全、可行的手术方式。
