Cervical arthroplasty lead to better overall success compared to anterior fusion .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(19):42 J Bone Joint Surg Am. 2011 Sep 21;93(18):1684-92. doi: 10.2106/JBJS.J.00476463 patients suffering from single-level degenerative disc disease were included in this trial to compare the outcomes of cervical disc arthroplasty and anterior cervical discectomy and fusion (ACDF). This publication aimed to assess the midterm safety and effectiveness of the Bryan cervical disc arthroplasty. 463 patients were randomized to receive either the Bryan disc or anterior cervical discectomy and fusion. The assessment at 48 months revealed that the cervical disc arthroplasty led to superior results in terms of pain, function, and overall success when compared to ACDF.

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Cervical arthroplasty can be an alternate treatment option to anterior cervical discectomy and fusion for patients suffering from single-level degenerative disc disease. A previous publication by the same authors reported the 2 year results from a trial that compared the Bryan cervical disc arthroplasty with anterior cervical discectomy and fusion. While cervical disc arthroplasty lead to better overall success, a longer follow-up study was required. Thus, this publication aimed to compare the 4 year clinical and functional outcomes of cervical disc arthroplasty versus cervical discectomy and fusion from the same trial.
ما هو سؤال البحث الرئيسي؟
Which method - cervical spine arthroplasty or anterior cervical discectomy and fusion - led to better overall success for the treatment of radiculopathy or myelopathy caused by single-level cervical disc disease, assessed at 48 months?
- At 4 years, the overall success was better in the arthroplasty group (85.1%) compared to the fusion group (72.5%) (P = 0.004).
- At 4 years, the mean NDI was lower in the arthroplasty group (13.2 (95% CI: 10.9 to 15.6)) in comparison to the fusion group (19.8 (95% CI: 16.5 to 23.2), P < 0.001).
- In terms of neurological success, the mean rates were 92.8% for the arthroplasty group and 89.9% for the fusion group; there was no significant difference (P > 0.05).
- The arm pain score improved rapidly for both groups, from a preoperative score of 71.2 in both groups to 16.6 (95% CI: 13.1 to 20.2) in the arthroplasty group and to 22.4 (95% CI: 17.7 to 27.1) in the fusion group at 4 years; the improvement was significantly better in the arthroplasty group (P = 0.028).
- Neck pain improved from 75.4 to 20.7 (95% CI: 17.0 to 24.4) in the arthroplasty group and from 74.8 to 30.6 (95% CI: 25.5 to 35.8) in the fusion group at 4 years; the improvement was significantly greater in the arthroplasty group at all time points (P < 0.05).
- At 4 years, the mean SF-36 physical component score improvement was significantly better (P = 0.007) in the arthroplasty group (from 32.6 to 48.4 (95% CI: 46.8 to 49.9) compared to the fusion group (from 31.8 to 44.9 (95% CI: 43.0 to 46.9).
- The rates of total and serious adverse events were similar between both groups.
ما الذي يجب أن أتذكره أكثر؟
This study demonstrated that cervical disc arthroplasty continued to provide superior results at 4 years in comparison to anterior cervical discectomy and fusion. The arthroplasty treatment led to significantly higher rate of overall success and greater improvements in NDI, neck and arm pain, and SF-36 physical component scores.
كيف سيؤثر ذلك على رعاية مرضاي؟
This study suggests that cervical disc arthroplasty provides better clinical improvement compared to cervical fusion. However, a longer-term follow-up study is required in order to investigate the potential problems related to bearing surface wear. Additionally, an assessment of adjacent-level disc degeneration and secondary surgeries should be conducted in the long-term follow-up.
