摘　　要：目的探讨单侧单节段Bioflex动态固定治疗腰椎间盘突出症的临床疗效.方法：47例暨南大学附属第一医院单节段腰椎间盘突出症患者行 Bioflex单侧单节段动态固定手术,记录手术耗时、术中出血量及术后住院时间等,并对比分析患者手术前后腰腿痛VAS评分、ODI评分、腰椎手术节段活动度、椎间隙高度等变化情况,分析手术治疗效果.结果：47例患者均获得随访, 随访时间16~26个月,平均（20±4）个月.腰痛VAS评分术前（7.54±1.65）,末次随访为（3.34±0.72）,有统计学差异（P 〈0.05）;腿痛VAS评分术前 （8.48±0.89）,末次随访（2.23±0.79）,差异有统计学意义（P 〈0.05）; ODI评分术前（84.21±6.48）,末次随访为 （25.71±6.23）,差异有统计学意义（P 〈0.05）;末次随访手术相邻节段ROM及椎间隙高度无明显丢失,无统计学差异（P 〉0.05）.随访期间未发现内固定松动、断裂、手术节段及临近节段不稳.结论：单侧单节段Bioflex动态固定治疗单节段腰椎间盘突出症中期临床疗效满意,可保留部分手术节段ROM及临近节段活动度,并降低手术后的腰椎不稳风险.Aim：To explore the therapeutic effect of single surgery segment unilateral Bioflex dynamic fixation in the treatment of degenerative disc disease （DDD）. Methods： 47 patients with the single segment DDD in the Department of Orthopedics, received unilateral Bioflex dynamic fixation. The clinical efficacy was evaluated by observing basic data such as operating time, blood loss, postoperative hospital days, VAS scores, ODI scores and imaging features such as the intervertebral range of motion （ROM）, intervertebral height and lumbar lordosis. Results： All patients had been followed-up over an average follow-up time of （20±4） months （16~26 months）, low back pain VAS score was significantly improved at the final follow-up （3.34±0.72）, compared with the preoperative （7.54±1.65） （P〈0.05）. Leg pain VAS score was significantly improved at the final follow-up （2.23±0.79）, compared with the preoperative （8.48±0.89） （P〈0.05）. ODI score was also improved at the final follow-up （25.71±6.23）, compared with the preoperative （84.21±6.48） （P〈0.05）. The vertebral height and ROM of adjacent segment showed no statistical significant difference between preoperative and final follow-up （P〉0.05）. During the follow-up period, there were no loosening or breakage of internal fixation and instability of operative level and adjacent segment. Conclusion：Unilateral Bioflex dynamic fixation can obtain satisfactory clinical efficacy in the treatment of single segment degenerative disc disease. The unilateral Bioflex dynamic fixation can preserve the operative level’s ROM to some degree and functional motion of adjacent segment, reduce the risk of lumbar instability caused by decompression at the same time.
