The ideal surgical treatment of spondylolisthesis still remains controversial. There are several methods of treatment and posterior lumbar interbody fusion (PLIF) is one of them. We analyze the results of spondylolisthesis treated by PLIF in term of radiological union, improvement of pre-operative symptoms like back pain, radiating pain and return to normal activities including that of employment, by the review of the medical records. Total of 72 patients, 20 male and 52 female and the age ranges from 15 to 68 years with the mean age being 44.38 years were included in the study. Thirty (41.66%) patients had isthmic spondylolisthesis, 26 (36.12%) had congenital spondylolisthesis, and 16 (22.22%) cases had degenerative spondylolisthesis. There were 38 (52.77%) cases of grade I, 14 (19.44%) cases of grade II and 20 (27.77%) cases of grade III according to the grading criteria of Meyerding. According to the evaluation criteria used by Stauffer and Coventry, 59 patients (81.94%) got good results, eight patients (11.11%) belonged to the fair group and five cases (6.94%) had the poor results. This study showed that PLIF is one of the effective and reliable techniques for the management of spondylolisthesis.
腰椎滑脱的理想手术治疗方法仍存在争议。治疗方法有多种，后路腰椎椎间融合术（PLIF）是其中之一。我们通过查阅病历，从影像学融合、术前症状如背痛、放射痛的改善以及恢复正常活动（包括工作）等方面分析了PLIF治疗腰椎滑脱的效果。本研究共纳入72例患者，其中男性20例，女性52例，年龄范围为15至68岁，平均年龄为44.38岁。30例（41.66%）患者为峡部裂性腰椎滑脱，26例（36.12%）为先天性腰椎滑脱，16例（22.22%）为退变性腰椎滑脱。根据Meyerding分级标准，I级38例（52.77%），II级14例（19.44%），III级20例（27.77%）。根据Stauffer和Coventry使用的评估标准，59例（81.94%）患者效果良好，8例（11.11%）属于一般组，5例（6.94%）效果较差。本研究表明，PLIF是治疗腰椎滑脱有效且可靠的技术之一。
