颈前路分节段减压融合治疗多节段颈椎病

摘要

Objective To evaluate the clinical value of the segmental anterior cervical decompression with fusion for treating multilevel cervical myelopathy.Methods 24 patients of multilevel cervical myelopathy with 3 or 4 consecutive segments were treated with segmental anterior cervical decompression with fusion.All patientst' cervical plain films,magnetic resonance imaging( MRI ) on preoperation and cervical plain films on postoperation were ohserved.The JOA scores of preoperation and 3 months postoperatively were collected.Results 24 cases were followed up from 3 months to 48 months, average 28 months.All patients improved their functional status in different degree.No complications such as graft nonunion and graft suhsidence occurred.The mean preoperative JOA score of all patients was ( 8.20 ±2.26 ),the postoperative of 3 months was ( 13.50 ± 1.28 ) , the average JOA recovery rate was 60.2％.Fusion rate was 100％.Conclusions The segmental anterior cervical decompression with fusion for treating multilevel cervical myelopathy appears to be effective in decompressing spinal cord, improving nerve functional status and restoring lordosis to the cervical spine with high fusion rate and fewer complications.%目的 评价颈前路分节段减压植骨融合术治疗多节段颈椎病的临床疗效.方法 对24例连续3或4个节段病变的颈椎病患者采用分节段减压融合术治疗.均行术前X线、MRI和术后X线片检查.均于术前及术后3个月进行JOA评分.结果 24例均获随访,时间3～48(28±20)个月.患者功能均有不同程度的改善.无植骨块不愈合、内置物下沉等并发症发生.JOA评分术前平均为(8.20±2.26)分,术后3个月平均为(13.50±1.28),改善率为60.2%,植骨融合率100%.结论 颈椎前路分节段减压融合术具有减压彻底、术后神经功能恢复好、恢复颈椎曲度、融合率高、并发症少等优点.
