各种内固定在颈椎不稳症外科治疗中的应用

回顾因颈椎不稳而采用各种内固定治疗的病例共53例，其中上颈椎30例，下颈椎23例。内固定器械为枕 颈CD或Cervifix,Apofix,Mage rl法 空心钉，Orionak或“AO”钢板，空心螺钉等。随访6－23个月，平均12个月。结果内固定术后骨性融合52例，1例Apofix寰枢椎后弓间骨块吸收。1例枕颈CD环椎后弓未切除，减压不彻底，再次行后弓切除手术。临床神经症状按JOA脊髓损伤功能17分法评定标准，术后功能改善率为14.3%-100%，平均为80％。

SURGICAL TREATMENT OF UNSTABLE CERVICAL SPINE WITH DIFFERENT INTERNAL FIXATION METHODS

53cases of patients were treated a variety of internal fixation apparatuses, including the occipito-cervical CD (OCCD), the Cervifix, Apofix, Orion or AO cervical plates and screws, and were followed-up for 6 to 23 months (average 12 months). Good osteal fusion was obtained in 52 cases of patients after the internal fixation. Absorption of grafted bone was observed in one patient who had the atla-axis fusion with the Apofix fixation. Secondary operation of decompression was done in one patient who had the occipito-cervical fusion with the fixation of OCCD without removal of the postenor arch of the atlas. According to the JOA criterion for spinal function, the improvement rates were 14.3% to 100% (average 80%).
