纳入标准:

Inclusion criteria

排除标准:

1: 任何一次SINRB前或手术前疼痛不明显,或患者主要症状为下肢无力、麻木 2: 手术效果无法证实责任神经根:例如拟行手术的减压或固定范围超过一个节段或者非单一神经根减压; 3: 同一神经根的神经纤维在两个或以上节段均存在可疑压迫,例如某节段侧隐窝狭窄伴其头侧节段中重度中央管狭窄(Lee 2级或3级),或L4-5侧方椎管狭窄伴同侧L5-S1极外侧突出或椎间孔重度狭窄(Lee 3级); 4: 孕妇、恶性肿瘤患者,或其他因具有手术禁忌症而不能进行手术的患者 5: 无法配合活动障碍的评估,例如合并严重听力障碍、精神疾病或其他语言交流障碍,或合并髋部或下肢器质性病变、脑梗后遗症、帕金森综合征、小儿麻痹症或其他可导致行走障碍的疾病

Exclusion criteria:

1.Absence of significant pain prior to SINRB or surgery, or lower limb weakness/numbness as the primary symptom; 2.The surgical outcome can't confirm the responsible nerve root: for example, the intended decompression or fusion scope involves more than one spinal segment, or non‑single nerve root decompression is planned; 3.Suspected compression of nerve fibers originating from the same nerve root exists at two or more segments. Examples include lateral recess stenosis at one level combined with moderate‑to‑severe central canal stenosis (Lee grade 2 or 3) at the cephalad adjacent level, or lateral spinal stenosis at L4‑5 combined with extreme lateral disc herniation or severe foraminal stenosis (Lee grade 3) at the same side of L5‑S1; 4.Pregnancy, active malignant tumor, or other surgical contraindications precluding elective surgery; 5.Inability to cooperate with activity impairment assessment, including but not limited to: concurrent severe hearing impairment, mental illness, language communication barriers, hip/lower limb organic lesions, cerebral infarction sequelae, Parkinson’s syndrome, poliomyelitis, or other diseases causing walking dysfunction.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

责任神经根判定的金标准参照既往文献,具体如下:术前腰椎影像学显示该神经根存在可疑压迫,对该神经根进行单一节段、单一神经根减压手术后,患者术后早期评估(下地活动第二天)中疼痛基本缓解或原有活动障碍消失。 非腰源性坐骨神经痛的判定标准参照既往文献:患者存在可疑坐骨神经痛,腰椎影像学显示腰5或骶1神经根存在可疑压迫,但行腰5和骶1神经根阻滞后患者疼痛或活动障碍仍明显残留,效果不满意,而在梨状肌局部封闭治疗、髋部疾病对症治疗、下肢外周神经阻滞等症治疗后症状获得更明显的改善。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

The gold standard for determining the responsible nerve root was referenced from previous literature as follows: Preoperative lumbar imaging showed suspected compression of the nerve root, and after performing single-level, single-nerve root decompression surgery, the patient's pain was substantially relieved or the original movement impairment disappeared during early postoperative evaluation (the second day after ambulation). The diagnostic criteria for non-lumbar sciatica were referenced from previous literature: The patient presented with suspected sciatica, and lumbar imaging showed suspected compression of the L5 or S1 nerve roots. However, after L5 and S1 nerve root blocks, the patient's pain or movement impairment remained significantly unresolved with unsatisfactory effects. In contrast, symptoms showed marked improvement after piriformis muscle local block therapy, symptomatic treatment for hip disorders, or lower extremity peripheral nerve block therapy.

盲法:

本研究采用盲法设计以控制偏倚。在选择性神经根鞘内阻滞(SINRB)诊断评估期间,受试者与独立结局评估者均实施完全设盲。 受试者与评估者均不知晓每一次注射的靶点为疑似症状性责任神经根,还是非责任神经根。仅向受试者告知预设临床规则:若单次 SINRB 后疼痛完全缓解,则终止后续阻滞操作。 此外,研究亦可对非责任神经根进行注射以作为阴性对照,受试者并不知晓责任神经根与非责任神经根的注射先后顺序。 独立评估者依据单独录制的视频资料,对每次 SINRB 操作前后进行临床评估。视频文件顺序经随机化处理,确保评估者无法知晓每位受试者接受 SINRB 操作的次数。

Blinding:

Blinding design was adopted for bias control. Both participants and independent outcome assessors remained fully blinded during diagnostic SINRB evaluation. Neither subjects nor assessors knew whether each injection targeted the suspected symptomatic responsible nerve root or a non‑responsible nerve root. Participants were only informed of the predefined clinical rule: once complete pain relief was achieved following a single SINRB, subsequent blocking procedures would be discontinued. In addition, an injection may also be administered to non‑responsible nerve roots to serve as a negative control, and participants would remain unaware of whether the responsible or non‑responsible nerve root was injected first. Independent assessors performed clinical evaluations before and after each SINRB using separately recorded video footage. The order of video files was randomized to ensure that assessors remained unaware of how many SINRB procedures each participant had undergone.
