人工颈椎间盘置换术的研究进展

前路融合术是目前治疗颈椎病的常规术式,但颈椎前路融合术后邻近节段的退变加速越来越受到人们的重视。融合术还引起脊柱的生物力学改变,且存在植骨和内固定器械的并发症及供骨区慢性疼痛等。此外,颈椎前路手术的主要目标是解除脊髓的压迫而不是融合,这些都是困扰脊柱外科医师的难题。人工颈椎间盘置换术可在进行脊髓减压并提供稳定的同时保持手术节段颈椎的活动度,为颈椎病的外科治疗开辟了新的途径。本文结合最新文献对该技术的发展和前景进行综述。

Progress in artificial cervical disc replacement

Although anterior cervical fusion has been a conventional surgical treatment for cervical spondylosis, concerns for the possible accelerated degeneration of adjacent segments after fusion have been growing. Fusion can also lead to other drawbacks, such as alteration of spinal biomechanics, graft and hardware complications, and chronic pain at the harvest site. In addition, it must be realized that decompression, not fusion, is the primary goal of anterior cervical surgery. Since the artificial cervical disc replacement can preserve enough motion after neural decompression with adequate stability, it provides a new surgical therapy for cervical spondylosis. This paper summarizes the progress in the related research field and makes comments on the current developments and future prospects of cervical arthroplasty.
