摘要
目的：研制钛合金颈椎空心螺纹式内固定器并将其用于治疗颈椎不稳的患者，包括颈椎病及急性颈椎间盘突出症行颈前路减压术后患者。方法：采用无磁性的医用钛合金加工成空心螺纹状结构，其壁多孔，有利于骨组织长入，促进椎间融合。用于颈椎病及急性颈椎间盘突出症前路减压术后稳定融合者４２例。术后摄颈椎Ｘ线片及ＣＴ检查，观察手术节段的稳定性和融合情况。结果：术后次日可下床活动。随访３～２６个月，手术节段稳定，术后３～６个月融合。结论：颈椎空心螺纹式内固定器使施术节段立即获得制动，方便术后护理并早日重返工作岗位。该术式安全简便，并且避免了取自体髂骨所引起的多种并发症。
bjective:Cervical hollow threaded fixator(CHTF) was designed and applied for the treatment of instability of the cervical spine following anterior decompression for cervical myelopathy or acute cervical discherniation. Methods: Titanium for medical use with no magnetism was made into hollow threaded structure with holes on the wall of the fixator. These holes faciliate bone growth easily and fusion of the bone segments in a short time. Fortytwo patients with cervical spondylosis and acute cervical disc herniation were stabilized using this technique after anterior decompression. X-ray films and CT were taken after operation to observe the stability and fusion of the segments. Results: The patients were allowed to walk next day after operation and followed up from 3 months to 26 months. The operated segments were stable and solid fusion was observed in 3-6 monthsafter operation. Conclusions: The immediate stability of the operated segments can be obtained by using CHTF technique. The patients were easy to be nursed and returned to their jobs early. The CHTF technique is safe and simple and eliminates the complications of autograft.
