目的：探讨经改良后路单开门侧块螺钉悬吊技术联合微型钛板固定治疗多节段脊髓型颈椎病的临床疗效。方法对58例颈椎病患者常规行后正中入路单开门椎管扩大成形术，门轴一侧3、5、7侧块采用Magerl方法置入直径3.2 mm、长度12 mm施乐辉带线锚钉，螺钉置入侧块后一端经棘突根部的预穿孔穿过，开门后拉紧丝线并打结，使椎板保持开门状态，同时4、6采用施乐辉微型钛板固定，术后颈部围领保护2周。结果平均随访15个月（7～19个月），术前JOA评分7.8分，40分法14.6分，术后平均评分15分,40分法35.4分。术后2个月颈部僵痛和后动受限者：轻度30例，中重度20例，术后6个月仅13例患者仍有轻度颈部疼痛、僵硬及活动受限，未见固定松动和再关门现象。结论改良后路单开门侧块螺钉悬吊技术联合微型钛板固定单开门椎管扩大成形术操作简单，安全有效，维持开门确实。术后患者颈部症状缓解明显，早期效果满意。

Objective To evaluate the clinical outcome of modified open door laminoplasty using an anchor system and titanium plate. Methods The clinical data of 58 patients with single door treatment of multiple segmental cervical spondylotic myelopathy using an anchor system and titanium plate ifxation remain the door in the opening position. Soft collar protection was applied for two weeks after operation.Results 58 cases of cervical spondylotic myelopathy were included in the study. The mean follow up was 15 months (7 to 19 months).the average pre-OP JOA score was 7.8 and 40 score was 14.6, post-OP JOA score was 15 and 40 score was 35.4.13cases had slingt axial symptom like neck pain, stiffness and restriction of neck movement tow months after operation. There was no cases of ifxation loosening and door reclosure.ConclusionThis modiifed open door laminoplasty using anchor system and titanium plate fixation method has the advantages of easy performing, good maintaining of elevate lamina, less neck symptoms and early commencing of mobilization.
