- W4328049058 abstract "To evaluate the effectiveness of modified recapping laminoplasty preserving the continuity of supraspinous ligament in the treatment of intraspinal benign tumors in upper cervical vertebrae and its influence on the stability of the cervical vertebrae.The clinical data of 13 patients with intraspinal benign tumors in upper cervical vertebrae treated between January 2012 and January 2021 were retrospectively analyzed. There were 5 males and 8 females, the age ranged from 21 to 78 years, with an average of 47.3 years. The disease duration ranged from 6 to 53 months, with an average of 32.5 months. The tumors located between C 1 and C 2. Postoperative pathology showed 6 cases of schwannoma, 3 cases of meningioma, 1 case of gangliocytoma, 2 cases of neurofibroma, and 1 case of hemangioblastoma. During operation the continuity of the supraspinal ligament were retained, the lamina ligament complex was lifted to expose the spinal canal via the approach of the outer edge of the bilateral lamina, and the lamina was fixed after the resection of the intraspinal tumors. Before and after operation, the atlantodental interval (ADI) was measured on three-dimensional CT; the effectiveness was evaluated by Japanese Orthopaedic Association (JOA) score, the neck dysfunction index (NDI) was used to evaluate the cervical function, and the total rotation of the cervical spine was recorded.The operation time was 117-226 minutes (mean, 127.3 minutes); the intraoperative blood loss was 190-890 mL (mean, 227.8 mL). The tumors were completely removed in all patients. There was no vertebral artery injury, aggravation of neurological dysfunction, epidural hematoma, infection, or other related complications. Two patients occurred cerebrospinal fluid leakage after operation, which were healed through electrolyte supplement and local pressure treatment of incision. All the patients were followed up 14-37 months, with an average of 16.9 months. Imaging examination showed no recurrence of tumor, displacement of vertebral lamina, loosening and displacement of internal fixator, and secondary reduction of vertebral canal volume. At last follow-up, JOA score significantly improved when compared with preoperative scores ( P<0.05). Among them, 8 cases were excellent, 3 cases were good, and 2 cases were medium, with an excellent and good rate was 84.6%. There was no significant difference in ADI, total rotation of the cervical spine, and NDI between pre- and post-operation ( P>0.05).The treatment of intraspinal benign tumors in upper cervical vertebrae with modified recapping laminoplasty preserving the continuity of the supraspinous ligament can restore the normal anatomical structure of the spinal canal and maintain the stability of the cervical spine.探讨保留棘上韧带连续性的改良椎板回植技术治疗上颈椎椎管内良性肿瘤的疗效及对颈椎稳定性的影响。.回顾分析2012年1月—2021年1月收治的13例上颈椎椎管内良性肿瘤患者临床资料。男5例,女8例;年龄21~78岁,平均47.3岁。病程6~53个月,平均32.5个月。肿瘤位于C 1、C 2之间。术后病理检查示神经鞘瘤6例、脊膜瘤3例、神经节细胞瘤1例、神经纤维瘤2例、血管母细胞瘤1例。术中保留棘上韧带的连续性,在椎板外缘切开后掀起椎板韧带复合体显露椎管,切除椎管内肿瘤后椎板回植固定。手术前后于三维CT上测量寰齿前间距(atlantodental interval,ADI),采用日本骨科协会(JOA)评分评价疗效,采用颈椎功能障碍指数(NDI)评估颈椎功能,并记录颈椎总体旋转度。.手术时间117~226 min,平均127.3 min;术中出血量190~890 mL,平均227.8 mL。患者肿瘤均完全切除,无椎动脉损伤、神经功能障碍加重、硬膜外血肿、感染等相关并发症发生;术后2例出现脑脊液漏,经补充电解质及切口局部加压处理后愈合。13例均获随访,随访时间14~37个月,平均16.9个月。影像学检查示肿瘤无复发,椎板无移位,内固定物无松动、移位,无继发椎管容积减小。末次随访时,JOA评分较术前显著改善( P<0.05),获优8例、良3例、中2例,优良率84.6%;手术前后ADI、颈椎总体旋转度及NDI比较差异均无统计学意义( P>0.05)。.采用保留棘上韧带连续性的改良椎板回植技术治疗上颈椎椎管内良性肿瘤,可恢复椎管正常解剖结构,较好地保持了颈椎稳定性。." @default.
