To observe the preliminary clinical outcome of using a new instrumentation Diapason system and to introduce the characterization and surgical technique of this new system for treatment of unstable lumbar spinal stenosis.
16 patients with unstable spinal stenosis who were treated by decompression, posterolateral intertransverse arthrodesis and transpedicle instrumentation of Diapason system, were analyzed retrospectively.
Lower back pain (LBP) of 16 patients were significantly alleviated after surgery (scores of LBP before operation: 47.5 +/- 0.8; scores of LBP after operation: 31.9 +/- 2.3, P < 0.001). There was no implant failure, no early or later infection and no neurological complications in 16 patients at an average of 6.2-month follow-ups. No pseudoarthrosis was observed on roentgenography.
Our short-term follow-up and limited cases study showed satisfactory preliminary result of treating unstable lumbar spinal stenosis with Diapason internal fixation.
观察使用新型器械Diapason系统的初步临床疗效，并介绍该新型系统治疗不稳定型腰椎管狭窄症的特点及手术技术。
回顾性分析16例采用减压、后外侧横突间融合及Diapason系统椎弓根内固定治疗的不稳定型椎管狭窄症患者。
16例患者术后下腰痛（LBP）明显缓解（术前LBP评分：47.5±0.8；术后LBP评分：31.9±2.3，P<0.001）。16例患者平均随访6.2个月，无内固定失败、无早期或晚期感染及无神经并发症。X线检查未发现假关节形成。
我们的短期随访及有限病例研究表明，Diapason内固定治疗不稳定型腰椎管狭窄症的初步结果令人满意。
