摘要:

背景:神经鞘瘤切除方式的选择关系着瘤体能否切净、能否有效避免肿瘤切除过程中牵拉损伤脊髓神经,最终关系着治疗的预后。
目的:分析椎管内、椎间孔区域神经鞘瘤行椎板关节突切除复合单侧或双侧钉棒系统置入内固定后的脊柱稳定性。
方法:对颈、胸、腰不同部位椎管内、椎间孔区神经鞘瘤48例患者行椎板关节突切除复合钉棒系统置入内固定治疗,其中管内神经鞘瘤34例行双侧螺钉固定,椎间孔区域神经鞘瘤14例行单侧螺钉固定。
结果与结论:内固定后3 d及内固定后3,6,12个月X射线复查结果示:内置物位置良好,植骨融合,无脊柱失稳、椎体滑脱现象。治疗后神经功能Bodford(1997)评分及生活质量评分均较治疗前显著提高(P < 0.01);治疗后Lovett分级评估肌力较治疗前显著提高(P < 0.01);治疗后疼痛程度分级(VRS)法疼痛较治疗前明显好转(P < 0.01)。48例患者神经鞘瘤均完全切除,内固定后有6例出现脑脊液漏,1例出现脑脊液感染,有1例因脑脊液感染行二次手术,3例因肿瘤侵蚀神经根行肿瘤神经根一并切除。表明对椎管内神经鞘瘤采用椎板切除双侧钉棒内固定、椎间孔区域神经鞘瘤采用部分椎板关节突切除单侧钉棒能够充分暴露肿瘤所在区域的视野,完整切除神经鞘瘤,有效避免损伤脊髓神经,更能有效维持脊柱稳定性,防止出现椎体滑脱、椎体失稳,其远期效果尚需进一步研究。

Abstract:

BACKGROUND: The choice of schwannoma resection is strongly associated with whether the tumor was completely resected, whether stretch during resection injures spinal nerves, and finally with the prognosis of treatment.
OBJECTIVE: To evaluate the spinal stabilization after laminectomy combining unilateral or bilateral nail-rod system for schwannoma in the spinal canal or intervertebral foramen.
METHODS: A total of 48 cases of schwannoma in the spinal canal or intervertebral foramen of neck, chest and waist underwent laminectomy combining unilateral or bilateral nail-rod system. 34 cases in spinal canal received bilateral nail-rod system, and 14 cases in the intervertebral foramen received unilateral nail-rod system.
RESULTS AND CONCLUSION: At 3 days and 3, 6, 12 months after internal fixation, radiograph results demonstrated that location of implants was good. Bone graft fusion was found. No spinal instability and vertebral slippage occurred. Neural functional score Bodford (1997) and quality of life score were significantly increased
after treatment (P < 0.01). Muscle strength assessed by Lovett grade was significantly elevated after treatment (P < 0.01). Pain evaluated by Virtual Rescan grade was significantly lessened after treatment (P < 0.01). Schwannoma was completely resected in 48 patients. After treatment, six patients affected leakage of cerebrospinal fluid. One case experienced infection of cerebrospinal fluid. One case had to undergo secondary operation due to the infection. Three cases received nerve root resection due to tumor erosion. These experimental results confirmed that laminectomy combining unilateral or bilateral nail-rod system for schwannoma in the spinal canal or intervertebral foramen has the advantage of the tumor fully exposed to the operator, which can help completely resect schwannoma and effectively avoid spinal nerve injury. Even more important thing is that the spinal stability is reconstructed by unilateral or bilateral nail-rod system, which prevents the occurrence of vertebral slippage and vertebral destabilization. Long-term effect still needs further research.
