【摘要】 目的:评价内窥镜下微创颈椎管扩大成形术(cervical microendoscopic laminoplasty,CMEL)治疗多节段脊髓型颈椎病的中长期治疗效果。方法:2010年1月~2013年1月我院采用CMEL治疗多节段脊髓型颈椎病患者19例,其中男12例,女7例,年龄56.0±10.5岁(38~72岁),病程15.0±6.3个月。其中三节段者3例,四节段者6例,五节段者10例,共166个椎板行双侧开槽微型钛板固定。比较患者术前和术后1周、3个月、1年、2年及末次随访时的JOA评分、手术节段椎管/椎体矢状径比值、颈椎活动度及颈椎曲度(C2~C7 Cobb角)。结果:19例手术时间为49~133min(114.0±19.9min),术中出血量100~375ml(219.0±70.5ml)。1例术中发生硬脊膜破裂,术后出现低颅压头痛,给予补液及止痛治疗5d后头痛逐渐缓解。19例患者均获得随访,随访5~8年,平均7.00±0.76年。术后1周、3个月、1年、2年及末次随访时的JOA评分与术前比较均明显增加(P<0.05),末次随访时JOA评分改善率为(70.0±6.9)%。术后1周、3个月、1年、2年及末次随访时的手术节段椎管/椎体矢状径比值与术前比较均明显增大(P<0.05),颈椎活动度、C2~C7 Cobb角与术前比较均无显著性差异(P>0.05)。在行双侧开槽微型钛板固定的166个椎板中,术后3个月发生骨性愈合有112个,愈合率为67.5%;术后1年发生骨性愈合有122个,愈合率为73.5%;末次随访时发生骨性愈合有128个,愈合率为77.1%。末次随访时微型钛板及螺钉位置良好,无钛板、螺钉断裂及螺钉松动。结论:CMEL治疗多节段脊髓型颈椎病具有较好的中长期治疗效果,是一种安全、可靠的手术方式。 |

【Abstract】 Objectives: To evaluate the mid-long-term effect of minimally invasive expansive laminoplasty for cervical spondylotic myelopathy by using microendoscopy. Methods: From January 2010 to January 2013, 19 patients with cervical spondylotic myelopathy treated by cervical microendoscopic laminoplasty(CMEL) in our hospital were reviewed in this study. There were 12 males and 7 females with a mean age of 56 years (range, 38-72 years). The mean course of disease was 15 months(range, 8.7-21.3 months). Among these patients, 3 segments, 4 segments and 5 segments laminoplasty were performed in 3, 6 and 10 cases respectively. A total of 166 vertebral laminae was bilaterally slotted and fixed. The JOA score, the sagittal diameter of spinal canal/body rate of surgical segment, the range of motion(ROM) of cervical spine and the alignment of cervical spine were analyzed at preoperation, 1 week after surgery, 3 months after surgery, 1 year after surgery, 2 years after surgery and the final follow-up respectively. Results: The mean operation time was 114.0±19.9min(range, 49-133min). The mean blood loss was 219.0±70.5ml(range 100-375ml). Dural rupture occurred in 1 case during operation and then it appeared hypotensive cranial pressure headache after operation, headache gradually eased after which was given rehydration and analgesic treatment for 5 days. All of the 19 patients achieved average 7.00±0.76 years followed-up(range, 5-8 years). The mean JOA scores at 1 week after surgery, 3 months after surgery, 1 year after surgery, 2 years after surgery and the final follow-up were significantly increased compared to the preoperative ones(P<0.05), and the improvement rate at the final follow-up was (70.0±6.9)%. The mean surgical segment sagittal diameter of spinal canal/body rate at 1 week after surgery, 3 months after surgery, 1 year after surgery, 2 years after surgery and the final follow-up were significantly increased compared to the preoperative ones(P<0.05). The mean cervical vertebra activity at 1 week after surgery, 3 months after surgery, 1 year after surgery, 2 years after surgery and the final follow-up showed no significant difference compared to the preoperative ones(P>0.05). The mean C2-C7 Cobb angle at neutral position at 1 week after surgery, 3 months after surgery, 1 year after surgery, 2 years after surgery and the final follow-up showed no significant difference compared to the preoperative ones(P>0.05). A total of 166 vertebral laminae was bilaterally slotted and fixed. At 3 months after surgery, 112 laminae were observed bone healing and the bone healing rate was 67.5%. At 1 year after surgery, 122 laminae were observed bone healing and the bone healing rate was 73.5%. 128 laminae were observed bone healing at the final follow-up and the bone healing rate was 77.1%. The micro-titanium plate and screw were fixed in good position, no titanium plate, screw fracture and screw loosening were found at the final follow-up. Conclusions: CMEL is a safe and reliable surgical method, which has a good mid-long-term therapeutic effect on cervical spondylotic myelopathy. |
