Fifty patients who had spinal stenosis associated with degenerative lumbar spondylolisthesis were prospectively studied clinically and radiographically to determine if concomitant intertransverse-process arthrodesis provided better results than decompressive laminectomy alone. There were thirty-six women and fourteen men. The mean age of the twenty-five patients who had had an arthrodesis was 63.5 years and that of the twenty-five patients who had not had an arthrodesis, sixty-five years. The level of the operation was between the fourth and fifth lumbar vertebrae in forty-one patients and between the third and fourth lumbar vertebrae in nine patients. The patients were followed for a mean of three years (range, 2.4 to four years). In the patients who had had a concomitant arthrodesis, the results were significantly better with respect to relief of pain in the back and lower limbs.
对50例患有与退变性腰椎滑脱相关的椎管狭窄症患者进行了前瞻性的临床和影像学研究，以确定同时进行横突间融合术是否比单纯减压性椎板切除术能取得更好的效果。其中有36名女性和14名男性。接受融合术的25例患者的平均年龄为63.5岁，未接受融合术的25例患者的平均年龄为65岁。41例患者的手术节段在第四和第五腰椎之间，9例患者的手术节段在第三和第四腰椎之间。患者平均随访三年（范围为2.4至四年）。在同时进行融合术的患者中，背部和下肢疼痛缓解方面的效果明显更好。
