In recent decades cervical arthroplasty, or cervical disc replacement, has been steadily increasing in popularity as a procedure for the treatment of degenerative pathologies of the cervical spine. This is based on an evolving body of literature that documents superior outcomes in cervical disc replacement over fusion, for both single and double level pathologies, in well selected patients. One of the more recent and popular implants currently on the market is the Mobi-C cervical artificial disc (LDR Medical; Troyes, France). In this paper we report on two cases where focal hypermobility was observed following total disc replacement using the Mobi-C cervical artificial disc. This is followed by a discussion as to potential contributing factors to this hypermobility in relation to both implant design, and operative technique, suggesting potential changes that might prevent this in future patients.
近几十年来,颈椎关节成形术,即颈椎间盘置换术,作为治疗颈椎退行性病变的一种手术,其受欢迎程度一直在稳步上升。这是基于不断发展的文献资料,这些资料表明,在精心挑选的患者中,无论是单节段还是双节段病变,颈椎间盘置换术的效果都优于融合术。目前市场上较新且受欢迎的植入物之一是Mobi-C颈椎人工椎间盘(LDR Medical;法国特鲁瓦)。在本文中,我们报告了两例使用Mobi-C颈椎人工椎间盘进行全椎间盘置换术后出现局部活动过度的病例。随后讨论了与植入物设计和手术技术相关的导致这种活动过度的潜在因素,并提出了可能在未来患者中预防这种情况的潜在改变。
