Long-term results of cervical interbody fusion with PMMA were evaluated in a retrospective study. X-ray films of 83 patients were obtainable. Post-operative follow-up in this series was between 15 and 20 years. The results show that PMMA is engrafted after about 2 years. Stable vertebral interbody fusion is obtained in about 90% of cases. Development of malignoma was not observed. Resorptive bone alterations, which can be seen in about 2% of cases one to two years after operation are shown not to be progressive. This process heals and stable fusion develops.
一项回顾性研究评估了聚甲基丙烯酸甲酯（PMMA）用于颈椎椎间融合的长期效果。可获取83例患者的X线片。该系列患者术后随访时间为15至20年。结果显示，PMMA在约2年后植入。约90%的病例获得了稳定的椎体间融合。未观察到恶性肿瘤的发生。术后一到两年约2%的病例可见的吸收性骨质改变并无进展。这一过程会愈合并形成稳定的融合。
