Context: Cervical disc arthroplasty (CDA) was developed for the treatment of cervical disc disease with the potential advantages of preservation of physiological motion at a discal level, thereby potentially reducing adjacent level stresses and degeneration, which were a known complication of anterior cervical arthrodesis. The objective of this study was the assessment of long‑term functional and radiological outcomes overtime in all the patients who underwent CDA from 2011 to 2019 at our institute. Materials and Methods: Forty‑eight patients who underwent CDA (2011–2019) with a minimum 2‑year follow‑up were retrospectively evaluated. The functional outcome included the Visual Analog Score (VAS) and Neck Disability Index (NDI). Radiographs were assessed for range of motion (ROM) at the index surgical level, presence of heterotopic ossification (HO), and adjacent segment degeneration. Results: The mean follow‑up was 5.79 ± 2.96 (2.16–11.75) years. Significant improvement (P < 0.05) was observed in the VAS (8.91 ± 2.52 [preoperative] to 0.89 ± 1.27 [follow‑up]) and NDI (65.5% ±23.06% [preoperative] to 4.79 ± 3.87 [follow‑up]) score. Motion at index level increased significantly from 5.53° preoperatively to 7.47°, and 92% of the implanted segments were still mobile (referring to the threshold of ROM> 3°). HOs are responsible for the fusion of 4/50 (8%) levels at the last follow‑up. Distal and proximal adjacent disc degeneration occurred in 36% and 28% of patients, respectively. No migration of the implant was observed on the radiograph. Conclusion: Our study showed favorable clinical outcome of CDA with preservation of ROM at the index surgical level. CDA can be a promising alternative to anterior cervical arthrodesis when properly indicated. [ABSTRACT FROM AUTHOR] |
