The objective of this study was to select factors related to the prognosis and curative effect for posterolateral fusion (PLF) of lumbar low-grade isthmic spondylolisthesis (LGIS). Of 125 patients who accepted PLF treatment, 119 obtained solid union in this prospective study. Statistical analysis was used to evaluate factors related to the prognosis and curative effect. Spondylolisthetic position (L4, L5), gender and postoperative percent disc height were not significant factors for the prognosis and curative effect. Length of disease history (LDH), preoperative Japanese Orthopaedic Association (JOA) score and postoperative percentage of slipping (% slip) were significantly related to postoperative JOA score and postoperative improved JOA score. LDH and postoperative % slip were significantly related to postoperative recovery rate. LDH, preoperative JOA score and postoperative % slip were independent related factors for the prognosis and improvement of LGIS. LDH and postoperative % slip were independent related factors for the curative effect. However, age, gender, spondylolisthetic position and postoperative percent disc height were not significant factors.
本研究的目的是筛选出与腰椎低度峡部裂性椎体滑脱（LGIS）后外侧融合术（PLF）预后及疗效相关的因素。在这项前瞻性研究中，125例接受PLF治疗的患者中有119例获得了牢固融合。采用统计学分析来评估与预后及疗效相关的因素。椎体滑脱位置（L4、L5）、性别及术后椎间盘高度百分比并非影响预后及疗效的显著因素。病程长度（LDH）、术前日本骨科协会（JOA）评分及术后滑脱百分比（% slip）与术后JOA评分及术后JOA评分改善情况显著相关。LDH及术后% slip与术后恢复率显著相关。LDH、术前JOA评分及术后% slip是LGIS预后及改善情况的独立相关因素。LDH及术后% slip是疗效的独立相关因素。然而，年龄、性别、椎体滑脱位置及术后椎间盘高度百分比并非显著因素。
