Artroplastia total de disco cervical com prótese de bryan. Resultados Clínicos e funcionais

Abstract

Objective: To evaluate results of cervical disc arthroplasty with the bryan prosthesis for treatment of cervicobrachial pain (radiculopathy) and spinal cord compression (myelopathy). Methods: From 2002 to 2007, the CECOL surgical staff has operated 65 patients. Only 28 patients were found in 2010 to a new data collection. The pre- and post-operative evaluation was conducted using the CSOQ questionnaire (Cervical Spine Outcomes Questionnaire). Odom criteria were used only in the postoperative evaluation. both were translated and adapted to local culture. Results: There was a significant symptomatic and functional improvement in most patients. The reduction of neck pain (axial) and brachial pain (radicular) was similar. Odom criteria showed 82.1% good and excellent results, 10% satisfactory and 7% poor. There was only one complication (3%) which was reversed with anterior arthrodesis. Conclusions: The total cervical disc arthroplasty has proved to be a safe and effective method to treat selected cases of cervical disc herniation with radiculopathy and/or myelopathy in the short and medium term.
