增生后纵韧带切除扩大减压治疗脊髓型颈椎病

目的：观察颈椎前路增生后纵韧带切除治疗脊髓型颈椎病的疗效。方法：设计后纵韧带切除术式及相应器械，在颈椎前路前骨减压基础上切除增生肥厚的后纵韧带，行扩大减压并植骨融合治疗脊髓型颈椎病59例。根据JOA评分判定脊髓功能恢复程度及恢复率。结果：随访6－32个月，神经功能恢复率为64％－100％。结论：颈椎前路切骨减压后行增生后纵韧带切除使病变节段减压更加彻底，有利于脊髓型颈椎病患者的神经功能恢复。

Cervical Spondylosis with Myelopathy Treated by Anterior Expending Decompression with Removal of Hypertrophy Posterior Longitudinal Ligament

Objective:To observe the effect of removal of hypertrophy posterior longitudinal ligament(PLL)on the results of cervical spondylosis with myelopathy treated by anterior decompression.Method:The expending decompression was performed in 59 cases of cervical spondylosis with myelopathy by removal of hypertrophy PLL after the facts of bony compression were cleared.The JOA score was used to assess the degree of myelopathy and the rate of functional recovery.Results:The patients were followed up from 6 to 32 months.The rate of the functional recovery of myelopathy was from 64% to 100%.Conclusion:The complete decompression can be obtained by the removal of hypertrophy PLL.This technique is benefit to the patients with cervical spondylotic myelopathy for their function recovery.
