From 1985 to 1994, 66 patients who had symptomatic degenerative spondylolisthesis of lumbar and lumbosacral levels managed by modified technique for decompressive laminectomy and postero-lateral spinal fusion. There were six males and sixty females with a mean age of 58.5 years (range, 47-73). Fifty- five patients had spondylolisthesis at L4-L5 level (51 were grade I and 4 were grade II), nine patients had spondylolisthesis at L5-S1 level (7 were grade I, 2 were grade II). There were two patients who had spondylolisthesis of both levels. Mean follow-up time was 48 months (range, 12-120 months). There were excellent and good results in 57 cases (86.4%), fair in 6 cases (9.1%). Three cases (5%) had poor results; 2 cases developed non-union, one case had L4 and L5 roots injury during operation. The overall fusion rate was 96 per cent. Solid spinal fusion occurred within 6 months. No further slip occurred in any cases in this study.
1985年至1994年，66例有症状的腰椎及腰骶部退行性椎体滑脱患者采用改良减压椎板切除术及脊柱后外侧融合术治疗。其中男性6例，女性60例，平均年龄58.5岁（范围47 - 73岁）。55例患者为L4 - L5节段椎体滑脱（I度51例，II度4例），9例患者为L5 - S1节段椎体滑脱（I度7例，II度2例）。2例患者为两个节段均有椎体滑脱。平均随访时间为48个月（范围12 - 120个月）。优良结果57例（86.4%），尚可6例（9.1%）。3例（5%）结果差；2例出现不愈合，1例术中发生L4和L5神经根损伤。总体融合率为96%。6个月内实现了牢固的脊柱融合。本研究中所有病例均未再发生滑脱。
