“…We would like to suggest an increase in the area of TPS and HA layers at each endplate of the Discover disc. HO was found in ten cases of Grade I or II (18.2 %) at the last follow-up, and its incidence was obviously less than in other studies [20][21][22]. Because the contribution of sagittal balance to operative and adjacent segmental longevity is likely to be more important than preservation of ROM [15], artificial cervical Fig.…”

Purpose The aim of this current study was to analyze the clinical outcomes after Discover cervical disc replacement and its effects on maintaining cervical lordosis and range of motion (ROM). The possible factors influencing postoperative ROM were analyzed. Method 27 men and 28 women with a mean age of 46.4 ± 8.7 years were prospectively followed up for 2 years. Clinical outcomes were assessed using Japanese Orthopedic Association (JOA), Neck Disability Index (NDI), visual analog scale (VAS) and Odom's criteria. Radiographic information including segment and overall alignment, functional spinal unit (FSU) and overall ROM, and disc heights were prospectively collected during the follow-up. The correlations between the postoperative FSU ROM at last follow-up and influencing factors were analyzed. Results Mean NDI, JOA and VAS scores showed statistical improvements at last follow-up. Anterior migration of the prosthesis was detected in six cases. Heterotopic ossification was observed in ten patients. Mean FSU angle, endplate angle of the treated level and mean overall cervical alignment were all improved significantly at last follow-up (P \ 0.001). However, mean FSU ROM of the treated segment significantly decreased postoperatively (P = 0.008), while mean overall ROM showed no significant differences. A significant correlation was found between preoperative FSU ROM and postoperative FSU ROM by the Pearson correlation coefficient (r = 0.325, P = 0.034). Multiple linear regression analysis confirmed that preoperative FSU ROM contributed independently to a model with a coefficient of determination of 0.37 (P = 0.034). Conclusions In the 2 years follow-up, the Discover cervical disc arthroplasty has provided satisfactory clinical outcomes. It was able to substantially restore segment and overall cervical alignment while partially maintaining segment and overall cervical ROM. Additionally, we found that postoperative FSU ROM positively correlated with preoperative FSU ROM.

“…This is reconfirmed by recent studies that compare outcomes of fusions and clinical results after prosthesis implantations. 17 The cervical spine disc prosthesis also shows good results, short-and medium-term, in cases with pre-existing defects of the spinal cord. This is reconfirmed by our study.…”

Study design: Comparative prospective study. Objectives: To determine functionality of the cervical spine when using ProDisc C in comparison with the conventional method of treatment (decompression and fusion) in paraplegics. Setting: Spinal Cord Injury Centre in Germany. Methods: Two homogeneous groups were studied. The patients were treated with ventral decompression and either had a fusion with an iliac bone graft and plate (group 1) or had received a disc replacement (group 2). Pre-and postoperatively, the subjective scores of SF 36 and Neck Disability Score were determined. Also, objective data of the Spinal Cord Independence Measure (SCIM) III and mobility of the cervical spine, using the neutral-0-method, were evaluated. Prosthesis implementation and union or fusion were monitored by X-rays. Complications and alterations of the neurology were recorded according to the American Spinal Injury Association Score. Results: Neurological remissions of the radicular syndrome that caused the operation were observed. In one case, the dislocation of the prosthesis necessitated an alternative treatment. Mobility of the cervical spine after 6 months was higher in group 2. Both groups showed signs of improvement in the Neck Disability Score and in SF 36. None of the two groups had changes in their SCIM score. One case in group 2 showed ventral blocking; all cases of group 1 fused successfully. Conclusion: Usage of prostheses results in improved total mobility of the cervical spine in comparison with the outcomes of a fusion. This study also confirmed these results in tetraplegics.

“…Nossos resultados foram semelhantes ao de diversos estudos multicêntricos atuais. Alguns desses utilizaram a artrodese anterior após dissectomia como grupo controle e que os resultados da artroplastia em curto prazo foram iguais ou até superiores ao da artrodese [20][21][22][23][24] . Os índices de complicações, segundo eles, foram em média mais frequentes na artroplastia, no entanto foram mais graves na artrodese (lesão medular, pseudoartrose e outros) 25 .…”

OBJETIVO: Avaliar resultados da artroplastia total disco cervical com a prótese de Bryan para tratamento da cervicobraquialgia (radiculopatia) e da mielopatia compressiva. MÉTODOS: No período de 2002 a 2007, a equipe da CECOL operou 65 pacientes. Somente 28 pacientes foram localizados em 2010 para uma nova coleta de dados. Foi feita avaliação pré e pós-operatória, utilizando-se o questionário CSOQ (Cervical Spine Outcomes Questionnaire). Os critérios de Odom foram utilizados somente na avaliação pós-operatória. Ambos foram traduzidos e adaptados para cultura local. RESULTADOS: Houve melhora funcional e sintomática significativa na maioria dos pacientes. A atenuação da dor cervical (axial) e braquial (radicular) foi semelhante. Os critérios Odom indicaram 82,1% de bons e ótimos resultados, 10% satisfatórios e 7% ruins. Houve apenas uma complicação (3%), que foi revertida com a artrodese anterior. CONCLUSÕES: A artroplastia total de disco cervical demonstrou ser um método seguro e eficaz para tratamento de casos selecionados de hérnia de disco cervical associada a radiculopatia e/ou mielopatia a curto e médio prazo.
