To explore the clinical and radiological outcomes of Discover artificial cervical disc arthroplasty and the range of motion status on adjacent segments for cervical spondylosis causing radiculopathy or myelopathy.
A total of 18 consecutive patients underwent cervical arthroplasty with the Discover artificial cervical disc at our hospital. Clinical and radiological follow-ups were conducted. Their radiographic parameters of treatment and adjacent segments were evaluated at Month 1, 3, 6, 12, 18 post-operation. And the Japanese Orthopedic Association (JOA) score, visual analog scale (VAS) pain score and Odom's scale were recorded and analyzed.
During follow-ups over an average of 15 months, there was no occurrence of vascular injury, severe complications or prosthesis displacement and loosening. The score of JOA was 7.2±1.8 at preoperation and 16.7±4.5 at postoperation. And the score of VAS was 8.15±1.65 at preoperation and 2.03±1.12 at postoperation.
Discover artificial cervical disc arthroplasty is efficacious and the patients recover quickly. Targeted cervical segments may be stabilized and their physiological ranges of motion preserved.
探讨Discover人工颈椎间盘置换术治疗神经根型或脊髓型颈椎病的临床及影像学疗效，以及相邻节段的活动度情况。
我院连续18例患者接受了Discover人工颈椎间盘置换术。进行了临床及影像学随访。在术后1、3、6、12、18个月评估其治疗节段及相邻节段的影像学参数。记录并分析日本骨科协会（JOA）评分、视觉模拟量表（VAS）疼痛评分及奥多姆量表。
平均随访15个月期间，未发生血管损伤、严重并发症或假体移位及松动。术前JOA评分为7.2±1.8，术后为16.7±4.5。术前VAS评分为8.15±1.65，术后为2.03±1.12。
Discover人工颈椎间盘置换术疗效显著，患者恢复快。可稳定目标颈椎节段并保留其生理活动度。
