Objectives The aim of this study was to evaluate the value and long-term effect of laminectomy or laminoplasty in spinal cord tumor surgery. Patients and methods Patients with spinal cord tumor treated in Department of Neurosurgery from January 2016 to October 2019 were included in this study. Posterior median approach tumor resection was preceded in 94 cases. Vertebral plate and ligament composite replant (laminoplasty group) was proceeded in 34 cases, and vertebral plate resection (laminectomy group) was proceeded in 60 cases. All patients were followed up and neurological function imagings were conducted 1 week, 3 months, and 6 months postsurgery to evaluate the surgical efficiency and spinal stability. Results Total resection was achieved in 84 patients (89.0%); subtotal resection was achieved in 10 patients (11%). There was no significant difference between thelaminectomy group and laminoplasty group in terms of operative time, surgical site, infection rate, cerebrospinal fluid (CSF) infection, CSF leak, and length of hospitalization ( P > 0.05). The incidence of postoperative spinal deformity was 15.0% in the laminectomy group and 11.7% in the laminoplasty group ( P > 0.05). Laminoplasty vs laminectomy was associated with a similar risk of progressive deformity. However, for the cervical patients, there is significant difference ( P < 0.05) in the spinal deformity. For the patients with incision vertebral segments >3, there is no significant difference in the spinal deformity ( P > 0.05). Bone fusion was achieved in 7 (20%) patients in the laminoplasty group. Laminoplasty vs laminectomy was associated with a similar risk of progressive deformity. Conclusion Vertebral plate and ligament composite replant is a simple and practical method in spinal cord tumor surgery. Neither every case got bone fusion nor positive results turned out in survival analysis, but it is still valuable in reducing spinal deformity, especially in cervical vertebra spinal cord tumor surgery.

椎板韧带复合椎板成形术在脊髓肿瘤手术中的应用:94例患者分析

目的 本研究的目的是评估椎板切除术或椎板成形术在脊髓肿瘤手术中的价值和长期效果。患者与方法 2016 年 1 月至 2019 年 10 月在神经外科接受治疗的脊髓肿瘤患者纳入本研究。94 例患者行后正中入路肿瘤切除术。行椎板韧带复合再植术(椎板成形组)34例,行椎板切除术(椎板切除组)60例。所有患者均在术后1周、3个月、6个月进行神经功能影像学检查,评价手术效率和脊柱稳定性。结果 84例(89.0%)患者实现全切除;10 例患者(11%)实现了次全切除。椎板切除组与椎板成形术组在手术时间、手术部位、感染率、脑脊液(CSF)感染、脑脊液漏出、住院时间等方面差异均无统计学意义( P > 0.05)。椎板切除组术后脊柱畸形发生率为15.0%,椎板成形术组为11.7%( P > 0.05)。椎板成形术与椎板切除术与进行性畸形的风险相似。但对于颈椎病患者,脊柱畸形存在显着差异(P<0.05)。切口椎体>3节的患者,脊柱畸形差异无统计学意义(P>0.05)。椎板成形术组 7 名 (20%) 患者实现了骨融合。椎板成形术与椎板切除术与进行性畸形的风险相似。结论椎板韧带复合再植是脊髓肿瘤手术简单实用的方法。在生存分析中,虽然不是每个病例都获得了骨融合,也没有出现阳性结果,但它在减少脊柱畸形方面仍然有价值,特别是在颈椎脊髓肿瘤手术中。
