摘　　要：目的:探讨单节段镜下融合术治疗合并骨质疏松症的腰椎退变性疾病的临床疗效。方法:纳入2018年6月~2022年2月因腰椎退行性疾病接受腰椎单节段镜下融合手术,且住院期间完善双能X线吸收法(dual-energy X-ray absorptiometry,DXA)骨密度检测的病例24例,其中男7例、女17例;年龄44~80岁,平均66.0±9.9岁,术后随访时间21.6±12.6(3~47)个月。按是否合并骨质疏松症分为2组,其中8例合并骨质疏松症(骨质疏松组),16例不合并骨质疏松症(对照组)。骨质疏松症病例及时予抗骨松治疗。镜下融合手术均采用工作内径7.1mm的同轴水介质大通道脊柱内镜。比较两组患者一般资料及围手术期指标,术前、术后3d及末次随访时使用疼痛视觉模拟量表(visual analogue scale,VAS)评分、日本骨科协会(Japanese Orthopaedic Association,JOA)评分及Oswestry功能障碍指数(Oswestry disability index,ODI)评价临床疗效。术后3d复查腰椎数字X线摄影(digital radiography,DR)及腰椎计算机体层摄影(computed tomography,CT)评价减压与内固定情况;末次随访时行腰椎DR者,评估螺钉松动及融合器沉降情况;术后随访超过6个月且复查腰椎CT者,判断融合情况。记录并比较两组患者并发症发生情况。结果:两组患者的年龄、性别、术前诊断、术前椎间隙高度、手术节段,术前VAS、JOA评分及ODI等均无统计学差异。骨质疏松组最低骨密度平均值T=-3.2±0.6,明显低于对照组T=-1.4±0.8(P=0.000)。骨质疏松组平均手术时间为429.9±135.2min,对照组平均手术时间327.4±68.2min,差异具有统计学意义(P=0.020)。术中影像辅助方式、出血量、单侧入路双侧减压(unilateral laminotomy for bilateral decompression,ULBD)例数、术后椎间隙高度、住院天数两组间无统计学差异。两组术后3d及末次随访时腰痛/腿痛VAS评分、JOA评分及ODI均较术前明显改善,差异有统计学意义(P<0.05);但两组间比较均无统计学�Objectives:To explore the clinical outcomes of single-level full-endoscopic lumbar interbody fusion for degenerative lumbar spine disorders combined with osteoporosis.Methods:24 consecutive patients with degenerative lumbar spine disorders who underwent single-level full-endoscopic lumbar interbody fusion and were detected by dual-energy X-ray absorptiometry(DXA)during hospitalization for bone mineral density(BMD)from June 2018 to February 2022 were enrolled,including 7 males and 17 females with an average age of 66.0±9.9 years old(range 44-80 years).The follow-up period was 21.6±12.6(3-47)months after operation.And the patients were divided into two groups of osteoporosis group(containing 8 osteoporotic cases)and control group(containing 16 non-osteoporotic cases).Anti-osteoporosis therapy was initiated on the diagnosis of osteoporosis.The surgery was performed using a 7.1mm inner-diameter full-endoscope.The general data and perioperative parameters were compared between the two groups.Before operation,on 3d after operation and at final follow-up,visual analogue scale(VAS)score for back and leg pain,Japanese Orthopaedic Association(JOA)score and Oswestry disability index(ODI)were used for evaluating clinical outcomes.Digital radiography(DR)and computed tomography(CT)were performed on postoperative 3d for neural decompression and implant position assessment.For patients who received DR examination,cage subsidence and screw loosening were recorded at the final follow-up;For patients who were followed-up for 6 months and more and examined with CT,fusion rate was evaluated.The complications were recorded and compared between the two groups.Results:No significant differences were found in age,gender,diagnosis,preoperative intervertebral height,surgical segment,preoperative VAS scores,JOA scores and ODI between the two groups.The average of the lowest T value was-3.2±0.6 for osteoporosis group,lower than the-1.4±0.8 for control group(P=0.000).The mean operative time was 429.9±135.2min for osteoporosis group,more
