摘要(Abstract)：
[目的]探讨Bryan人工颈椎间盘置换术缓解颈椎病神经症状和体征,提高患者的生活质量,并保持颈椎稳定和节段活动。[方法]对19例23个椎间盘的人工颈椎间盘置换术进行了随访。随诊时间:8~76个月,平均29个月。其中脊髓型颈椎病15例,其他4例。男12例,女7例;年龄35~52岁,平均40.5岁。单节段置换16例,双节段2例,3节段1例。[结果]术中或术后没有神经和血管损伤的并发症。JOA评分从平均8.6分增加到15.8分。没有假体下沉和明显偏移。置换节段稳定并部分恢复了颈椎正常的活动范围,前屈和后伸活动范围是4.68°(3.6°~6.1°);左右侧屈的活动范围是3.51°(2.5°~4.6°)、3.42°(2.6°~4.3°)。CT和MRI随访表明2/23节段的假体偏移<1.5 mm。颈椎的生理弧度没有明显的丢失。置换节段假体周围没有骨化。[结论]19例人工颈椎间盘置换术取得了满意的近期疗效。与颈椎前路椎间盘摘除植骨融合术最大的不同点是患者恢复快,没有颈椎活动受限的缺陷。但至少需要5年的长期随访来评价假体的功能和对邻近节段的影响。
