The B.O.P. biocopolymer is a bioresorbable, biocompatible product which can ossify. It has been used in 45 spinal arthrodesis, 42 times in cervical region but three in lumbar spine. The authors report their results after a follow-up period of 8 to 28 months. Persistent cervical pain has been noted in 9 cases. This was the most important postoperative complaint. Graft ossification has nevertheless been observed only in 40% of cases, as proved by simple X rays or/and scanner examination over a 26 months period. An osseous overproduction with posterior osteophytes could otherwise be observed. The authors remains cautious about using moreover this kind of graft, at least in its actual presentation, though the clinical results can be compared with these obtained with osseous autograft.
B.O.P.生物共聚物是一种可生物吸收、生物相容且能骨化的产品。它已用于45例脊柱融合术，其中42例用于颈椎区域，3例用于腰椎。作者报告了8至28个月随访期后的结果。9例出现持续性颈部疼痛，这是最重要的术后主诉。不过，通过简单X线或/和26个月期间的扫描检查证明，仅40%的病例观察到植骨骨化。否则可观察到伴有后骨赘的骨质过度增生。尽管临床结果可与自体骨移植获得的结果相比较，但作者对于使用这种移植物仍持谨慎态度，至少就其目前的形式而言。
