METHODS: A retrospective review was performed of a consecutive case series of patients who underwent either prone or lateral, single-position LLIF by a single surgeon. All cases involved the L4-L5 level. Demographic data, perioperative details, clinical outcomes, and preoperative and postoperative lumbar lordosis were recorded.
RESULTS: Sixty-three patients underwent lateral and 16 patients underwent prone single-position LLIF. Demographics and average interbody size were similar between groups. Operative time, change in lumbar lordosis, and length of hospital stay did not differ between the 2 positions. Both groups performed similarly in terms of preoperative and postoperative visual analog score pain score and complications. Patients who underwent lateral position LLIF ambulated farther on postoperative day 1 (250 feet vs. 200 feet, P = 0.015). Average time to follow up was 53 weeks.
CONCLUSIONS: This study demonstrates promising preliminary results indicating that single-position LLIF performs well, even at the L4-L5 level, in both the prone and lateral positions.
方法:对连续病例系列患者进行回顾性分析,这些患者接受了俯卧或侧卧,所有病例均涉及L4-L5水平。人口统计数据,围手术期细节,临床结果,记录术前、术后腰椎前凸。
结果:63例患者接受侧卧位,16例患者接受俯卧单位置LLIF。各组之间的人口统计学和平均椎体间大小相似。手术时间,腰椎前凸的改变,两个位置之间的住院时间没有差异。两组患者术前和术后VAS疼痛评分相似,和并发症。在术后第1天接受侧卧位LLIF的患者走得更远(250vs.200英尺,p=0.015)。平均随访时间为53周。
结论:这项研究显示了有希望的初步结果,表明单位置LLIF表现良好,即使在L4-L5级别,在俯卧和侧卧位。
