From 1978 to 1983, 54 consecutive patients with unstable degenerative spondylolisthesis were treated by medial facetectomies and posterolateral fusion with combined distraction and compression rod instrumentation. The average period of follow-up observation was 30 months. Twenty-five patients had a combination of disc herniation or instability, excluding olisthesis. Single-level fusion was performed in 29 patients, two-level in 23, and three-level in two. Preoperative low-back pain in 87.0% and sciatica in 66.7% were reduced to 7.5% and 5.6%, respectively, at follow-up treatment. Preoperative neurogenic intermittent claudication in 63.0% and neurogenic bladder in 11.1% disappeared completely in all patients at follow-up examination. The solid fusion rate was 96.3%. Difference between the values of %-slip and slip-angle before surgery and those at follow-up examination was not statistically significant. Rod breakage occurred in two patients with pseudarthrosis. The overall clinical results were satisfactory relief of clinical symptoms and regression of physical signs, with a high rate of solid fusion.
1978年至1983年，对54例连续性不稳定退变性腰椎滑脱患者行小关节内侧切除术及后外侧融合术，并采用撑开加压棒内固定。平均随访观察期为30个月。25例患者合并椎间盘突出或不稳定，但不包括腰椎滑脱。29例行单节段融合，23例行双节段融合，2例行三节段融合。随访时，术前87.0%的下腰痛和66.7%的坐骨神经痛分别降至7.5%和5.6%。随访检查时，术前63.0%的神经源性间歇性跛行和11.1%的神经源性膀胱功能障碍在所有患者中完全消失。坚固融合率为96.3%。术前滑脱百分比和滑脱角与随访检查时的值之间的差异无统计学意义。2例假关节患者发生棒断裂。总体临床结果为临床症状得到满意缓解，体征消退，坚固融合率高。
