Efficacy of Cage Placement Without Plate in Patients With Cervical Myelopathy With Single-Level Affection

Abstract

Objective: To determine the efficacy of PEEK (Poly-ether-ether-ketone) cage without plate for the treatment of single-level cervical spondylosis. Methods: Ten patients with cervical myelopathy data, with a single-level root condition, seen at the outpatient clinic of the Neurosurgery Service, operated in 2016, mean age 53 years, 6 (60%) female, 4 (40%) obese, 3 (30%) smokers. The Cloward technique was used by anterior approach, discectomy, and PEEK cage placement. Results: At six months of surgery, 100% of the patients had increased intervertebral space, with a 100% reduction in osteophytes; only one patient had dysphagia, no patient had lesion of the adjacent segment and 10% had persistent root pathology. Cervical lordosis was observed in 90% of the patients and arthrodesis in 100% of the cases. Conclusions: Anterior approach arthrodesis using PEEK cage without cervical plate is effective as a treatment of cervical myelopathy in a single level.Keywords: Cervical vertebrae; Arthrodesis; Cervical; Cervical spondylosis. RESUMO Objetivo: Determinar a eficácia da do uso de cage em PEEK (poli-éter-éter-cetona), sem placa para o tratamento de espondilose cervical em um único nível. Métodos: Dez pacientes com dados de mielopatia cervical com afecção radicular em um só nível, atendidos no ambulatório do Serviço de
