摘要:

背景:目前不同地区修复原发性腰椎椎间隙感染的方式各不相同,主要方式分为前路、后路及前后路联合修复。而后路修复方式中,肌间隙入路方式得到不少同道的认可,该方案相较于传统后正中入路有其独特优势。
目的:评价经后路椎旁肌间隙入路行病灶清除植骨椎弓根螺钉置入内固定修复原发性腰椎椎间隙感染的临床效果。
方法:回顾性分析13例原发性腰椎椎间隙感染患者的临床资料,其中L2-L3 1例,L3-L4 2例,L4-L5 4例,L5-S1 6例。所有患者腰部疼痛明显,其中9例有下肢放射疼痛症状。13例患者均采用经后路正中切口椎旁肌间隙入路病灶清除植骨椎弓根螺钉置入内固定治疗,治疗后应用目测类比评分法及腰椎日本骨科协会(JOA)功能评分评价临床疗效。
结果与结论:患者随访12-18个月,无复发,所有患者X射线复查无内固定松动、断裂,均骨性融合。目测类比评分结果显示:平均目测类比评分治疗前8.15分,治疗后1周2.15分,末次随访1.00分,差异有显著性意义(P < 0.05),表明治疗前后疼痛对比差异有显著性意义,治疗后疼痛症状明显缓解。JOA腰椎功能评分结果显示,治疗后所有患者均显效,其中疗效优9例,良3例,中1例,总优良率为92%。提示一期经后路肌间隙入路病灶清除植骨椎弓根螺钉置入内固定为原发性腰椎椎间隙感染患者提供了一种良好的修复方法,可通过椎间孔可直接到达椎间隙,保留了中央的棘突和椎板,减少了对椎旁肌的损伤,同时保存了脊柱韧带复合体,而坚强的脊柱内固定有利于植骨融合,修复后保持了脊柱的稳定性。

Abstract:

BACKGROUND: The method in repair of primary lumbar intervertebral infection is different in different positions, mainly containing anterior, posterior and anteroposterior pathways. In posterior pathway, muscle gap approach is recognized by many fellows. This program has its special advantage compared with conventional posteromedial approach. 
OBJECTIVE: To evaluate the clinical effects of debridement, bone graft and internal fixation of pedicle screw placement in repair of primary lumbar intervertebral infection through posterior paraspinal muscle approach.
METHODS: Clinical data of 13 patients with primary lumbar intervertebral infection were analyzed retrospectively. There were one case of L2-L3, two cases of L3-L4, four cases of L4-L5 and six cases of L5-S1. Lumbar pain was 
obvious in all patients. Nine cases suffered from radioactive lower limb pain. All patients received debridement, bone graft and internal fixation of pedicle screw placement through paraspinal muscle approach via posteromedial incision. After treatment, clinical effects were evaluated using Visual Analog Scale and lumbar Japanese Orthopaedic Association scores.
RESULTS AND CONCLUSION: All patients were followed up for 12-18 months, no recurrence. X-ray review demonstrated bony fusion, so loosening and breakage were not found in all patients. Visual Analog Scale scores revealed that Visual Analog Scale score was 8.15 preoperatively, 2.15 at 1 week postoperatively, 1 at final follow-up, showing significant difference (P < 0.05). There was significant difference in pain between pre-treatment and post-treatment, and pain apparently relieved after treatment. Lumbar Japanese Orthopaedic Association score showed that effective outcomes were found in all patients after treatment, including nine cases of excellent effects, three cases of good effects, one case of average effects, with the excellent and good rate of 92%. Above findings confirmed that one-stage debridement, bone graft and internal fixation of pedicle screw placement through posterior muscle gap approach provides a good repair method for patients with primary lumbar intervertebral infection. It can achieve intervertebral space directly through intervertebral foramen, retain the central spinous process and lamina, reduce the injury to paraspinal muscle, and keep spinal ligament complex. However, strong spine fixation contributes to bone fusion, and keeps the stability of the spine after repair.
