A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for low-grade degenerative spondylolisthesis.
A total of 239 patients who underwent posterior lumbar fusion between January 2011 and January 2015 were included in this analysis. We investigated patient characteristics, surgical characteristics, and radiographic characteristics.
The mean visual analog scale (VAS) score of LBP decreased dramatically after the operation. The mean preoperative VAS score was greater in patients with severe lumbar multifidus (LM) intramuscular adipose tissue (IMAT). The postoperative VAS score was dramatically lower in patients with shorter symptom duration. Postoperative LBP disappeared more often in patients with shorter symptom duration. LBP VAS changing showed significant differences in different symptom duration groups and LM IMAT groups.
LM IMAT and symptom duration were risk factors for postoperative LBP. Patients with severe LM IMAT reported more severe LBP before the operation. Postoperative LBP disappeared more often in patients with shorter symptom duration.
进行一项回顾性研究以阐明低度退行性腰椎滑脱症术后下腰痛（LBP）的危险因素。
本分析纳入了2011年1月至2015年1月期间接受后路腰椎融合术的239例患者。我们调查了患者特征、手术特征和影像学特征。
术后LBP的平均视觉模拟量表（VAS）评分显著下降。严重腰大肌（LM）肌内脂肪组织（IMAT）患者术前VAS平均评分更高。症状持续时间较短的患者术后VAS评分显著更低。症状持续时间较短的患者术后LBP更常消失。LBP的VAS变化在不同症状持续时间组和LM IMAT组中显示出显著差异。
LM IMAT和症状持续时间是术后LBP的危险因素。严重LM IMAT的患者术前报告的LBP更严重。症状持续时间较短的患者术后LBP更常消失。
