棘突间CoflexTM非融合固定的临床应用及疗效分析

Clinical application and efficacy analysis of non-fusion fixation using interspinous implantation CoflexTM

目的评价棘突间Coflex非融合固定治疗腰椎管狭窄症的临床效果及应用前景。方法对腰椎管狭窄症121例采用后路双侧椎板开窗减压,棘突间Coflex非融合固定手术。其中119例行单节段棘突间Coflex固定,2例行双节段棘突间Coflex固定。结果 121例术后症状均得到明显改善,平均手术时间40.24 min,平均失血量51.43 ml;术前下腰椎JOA评分平均为13.62分,术后为25.06分;术前ODI评分平均为67.36%,术后为14.33%;术前腰痛VAS评分为7.89分,术后为2.01分;术前腿痛VAS疼痛评分平均为8.44分,术后为1.22分。结论应用双侧椎板开窗减压,棘突间Coflex非融合固定治疗腰椎管狭窄症具有良好的近期临床疗效。

Objective To investigate the short-term clinical outcome of non-fusion technique using a kind of interspinous implantation Coflex treatment for lumbar spine degenerative diseases. Methods A total of 121 cases of stenosis or lumbar disc herniation were evaluated. Of which, 119 cases were implanted a single segmental interspinous Coflex fixation while 2 cases were implanted two segmental interspinous Coflex fixations. Results All cases achieved fairly good clinical outcome. The average operation time was 40.24 rain, and the average blood loss was 51.43 ml. The mean JOA score was 13.62 points preoperative while 25.06 points postoperative, the mean ODI score was 67.36% preoperative while 14.33% postoperative, the mean VAS score in low back pain was 7.89 points preoperative while 2.01 points postoperative, and the mean VAS score in leg pain was 8.44 points preoperative while 1.22 points postoperative. Conclusion The application of interspinous implantation Coflex treatment for lumbar spine stenosis showed fairly good short-term clinical outcome.
