OBJECTIVE Several large-scale clinical trials demonstrate the efficacy of 1- and 2-level cervical disc arthroplasty (CDA) for degenerative disc disease (DDD) in the subaxial cervical spine, while other studies reveal that during physiological neck flexion, the C4–5 and C5–6 discs account for more motion than the C3–4 level, causing more DDD. This study aimed to compare the results of CDA at different levels. METHODS After a review of the medical records, 94 consecutive patients who underwent single-level CDA were divided into the C3–4 and non-C3–4 CDA groups (i.e., those including C4–5, C5–6, and C6–7). Clinical outcomes were measured using the visual analog scale for neck and arm pain and by the Japanese Orthopaedic Association scores. Postoperative range of motion (ROM) and heterotopic ossification (HO) were determined by radiography and CT, respectively. RESULTS Eighty-eight patients (93.6%; mean age 45.62 ± 10.91 years), including 41 (46.6%) female patients, underwent a mean follow-up of 4.90 ± 1.13 years. There were 11 patients in the C3–4 CDA group and 77 in the non-C3–4 CDA group. Both groups had significantly improved clinical outcomes at each time point after the surgery. The mean preoperative (7.75° vs 7.03°; p = 0.58) and postoperative (8.18° vs 8.45°; p = 0.59) ROMs were similar in both groups. The C3–4 CDA group had significantly greater prevalence (90.9% vs 58.44%; p = 0.02) and higher severity grades (2.27 ± 0.3 vs 0.97 ± 0.99; p = 0.0001) of HO. CONCLUSIONS Although CDA at C3–4 was infrequent, the improved clinical outcomes of CDA were similar at C3–4 to that in the other subaxial levels of the cervical spine at the approximately 5-year follow-ups. In this Asian population, who had a propensity to have ossification of the posterior longitudinal ligament, there was more HO formation in patients who received CDA at the C3–4 level than in other subaxial levels of the cervical spine. While the type of artificial discs could have confounded the issue, future studies with more patients are required to corroborate the phenomenon.

Abstract BackgroundCervical disc arthroplasty (CDA) has been demonstrated in clinical trials as an effective and safe treatment for patients diagnosed with radiculopathy and/or myelopathy. However, the current CDA indication criteria based on the preoperative segmental range of motion (ROM), comprise a wide range of variability. Although the arthroplasty level preserved ROM averaged 7°-9° after CDA, there are no clear guidelines on preoperatively limited or excessive ROM at the index level, that could be considered as suitable for CDA in any given trials.MethodsPatients who underwent CDA between January 2008 to October 2018 using Prestige-LP discs in our hospital, were reviewed retrospectively. They were divided into the small-ROM (≤5.5°) and the large-ROM (> 12.5°) groups according to preoperatively index-level ROM. Clinical outcomes, including the Japanese Orthopedics Association (JOA), Neck Disability Index (NDI), and Visual Analogue Scale (VAS) scores, were evaluated. Radiological parameters, including cervical lordosis, disc angle (DA), global and segmental ROM, disc height (DH), and complications were measured.ResultsOne hundred and twenty-six patients, with a total of 132 arthroplasty segments were analyzed. There were 64 patients in the small-ROM and 62 in the large-ROM group. There are more patients diagnosed with cervical spondylosis in the small-ROM than in the large-ROM group (P=0.046). Patients in both groups had significantly improved in JOA, NDI, and VAS scores after surgery, but the intergroup difference was not significant. Patients in the small-ROM group increased dramatically in cervical lordosis, global and segmental ROM postoperatively (P < 0.001). However, global and segmental ROM paradoxically decreased in the large-ROM group postoperatively (P < 0.001). Patients in the small-ROM group had lower DH preoperatively (P=0.012), and a higher rate of heterotopic ossification (HO) postoperatively (P=0.037).ConclusionPatients with preoperatively limited or excessive segmental ROM could achieve satisfactory clinical outcomes at 3 years postoperatively. Patients with limited segmental ROM had more, and severe HO and significantly increased segmental mobility, which decreased in patients with excessive segmental ROM after surgery.
