To introduce a new technique using OsteoMed M3 titanium plate and screws for fixation of the posterior elements in the open position after expansive unilateral open-door laminoplasty and evaluate its clinical effect.
Sixteen patients with multilevel cervical disc herniation and canal stenosis were treated with an expansive unilateral open-door laminoplasty using OsteoMed M3 plate and screws, and the follow-up period lasted for over 6 months.
Most of the patients had marked neurological improvement after the surgery. The mean Japanese Orthopaedic Association (JOA) score of the patients increased significantly from 9.06-/+2.380 (range 5 to 13) before surgery to 13.63-/+1.408 (range 11 to 16) at the final follow-up (P<0.005), with a mean recovery rate of 57.5%. One patient without postoperative neurological improvement underwent an additional anterior multilevel corpectomy. Bone fusion of the surgical lamina was achieved in all the cases without canal stenosis.
Unilateral open-door laminoplasty with OsteoMed M3 titanium plate and screw fixation can effectively maintain the expansion of the spinal canal and resist closure while preserving the spinal alignment and stability. This modified technique is easy to perform and is associated with a low complication rate.
介绍一种在扩大性单侧开门椎板成形术后使用OsteoMed M3钛板及螺钉固定后方结构的新技术，并评估其临床效果。
16例多节段颈椎间盘突出症合并椎管狭窄患者接受了使用OsteoMed M3钛板及螺钉的扩大性单侧开门椎板成形术治疗，随访时间超过6个月。
大多数患者术后神经功能有明显改善。患者的日本骨科协会（JOA）评分均值从术前的9.06±2.380（范围5至13）显著提高至末次随访时的13.63±1.408（范围11至16）（P<0.005），平均恢复率为57.5%。1例术后神经功能未改善的患者接受了额外的前路多节段椎体次全切除术。所有无椎管狭窄病例的手术椎板均实现了骨融合。
采用OsteoMed M3钛板及螺钉固定的单侧开门椎板成形术能有效维持椎管扩大并防止闭合，同时保持脊柱对线和稳定性。这种改良技术操作简便，并发症发生率低。
