Retrospective.
To compare the clinical and radiological outcomes of posterolateral lumbar interbody fusion (PLIF) and posterolateral lumbar fusion (PLF) in monosegmental vacuum phenomenon within an intervertebral disc.
The vacuum phenomenon within an intervertebral disc is a serious form of degenerative disease that destabilizes the intervertebral body. Outcomes of PLIF and PLF in monosegmental vacuum phenomenon are unclear.
Monosegmental instrumented PLIF and PLF was performed on 84 degenerative lumbar disease patients with monosegmental vacuum phenomenon (PLIF, n=38; PLF, n=46). Minimum follow-up was 24 months. Clinical outcomes of leg and back pain were assessed using visual analogue scales for leg pain (LVAS) and back pain (BVAS), and the Oswestry disability index (ODI). The radiographic outcome was the estimated bony union rate.
LVAS, BVAS, and ODI improved in both groups. There was no significant difference in the degree of these improvements between PLIF and PLF patients (p>0.05). Radiological union rate was 91.1% in PLIF group and 89.4% in PLF group at postoperative 24 months (p>0.05).
No significant differences in clinical results and union rates were found between PLIF and PLF patients. Selection of the operation technique will reflect the surgeon's preferences and patient condition.
回顾性研究。
比较后路腰椎椎间融合术（PLIF）和后路腰椎融合术（PLF）治疗单节段椎间盘真空现象的临床和影像学结果。
椎间盘内的真空现象是一种严重的退行性疾病形式，会使椎体不稳定。PLIF和PLF治疗单节段真空现象的结果尚不清楚。
对84例患有单节段真空现象的退行性腰椎疾病患者进行单节段器械辅助PLIF和PLF手术（PLIF组，n = 38；PLF组，n = 46）。最短随访时间为24个月。使用腿痛视觉模拟量表（LVAS）和背痛视觉模拟量表（BVAS）以及Oswestry功能障碍指数（ODI）评估腿痛和背痛的临床结果。影像学结果为估计的骨融合率。
两组患者的LVAS、BVAS和ODI均有所改善。PLIF组和PLF组患者在这些改善程度上无显著差异（p>0.05）。术后24个月，PLIF组的影像学融合率为91.1%，PLF组为89.4%（p>0.05）。
PLIF组和PLF组患者在临床结果和融合率方面无显著差异。手术技术的选择将反映外科医生的偏好和患者的病情。
