The purpose of this study was to compare the clinical outcome of surgery using robot-assisted posterior interbody fusion with that using freehand posterior interbody fusion in patients with degenerative spinal disease.
78 participants with degenerative spinal disease were randomly allocated (1:1) to the minimally invasive (MIS), posterior lumbar interbody fusion (Robot-PLIF) or conventional, freehand, open-approach, posterior lumbar interbody fusion (Freehand-PLIF).
The baseline-adjusted scores on the Oswestry Disability Index (ODI) in both groups at 1 year after surgery were not different (P = 0.688). However, the decrease in disc height at the proximal adjacent segment was significantly less in the Robot-PLIF group than in the Freehand-PLIF group (P = 0.039).
One-year surgical outcomes including Visual Analog Scale, ODI and Short Form-36 did not differ between the two groups. The disc height in the proximal adjacent segment was significantly less decreased in the Robot-PLIF group than in the Freehand-PLIF group.
本研究旨在比较机器人辅助后路椎间融合术与徒手后路椎间融合术治疗退行性脊柱疾病患者的临床疗效。
78例退行性脊柱疾病患者被随机（1:1）分配至微创（MIS）后路腰椎椎间融合术（机器人辅助PLIF）组或传统徒手开放入路后路腰椎椎间融合术（徒手PLIF）组。
术后1年两组患者经基线调整后的Oswestry功能障碍指数（ODI）评分无差异（P = 0.688）。然而，机器人辅助PLIF组近端相邻节段椎间盘高度的降低明显少于徒手PLIF组（P = 0.039）。
两组患者术后1年的手术效果，包括视觉模拟评分、ODI和简明健康状况调查量表36项评分，并无差异。机器人辅助PLIF组近端相邻节段的椎间盘高度降低明显少于徒手PLIF组。
