ABSTRACT

ABSTRACT Objective: Analysis of the use of polyetheretherketone (PEEK) cages for atlantoaxial facet realignment and distraction for treatment of basilar invagination by Goel technique. Method: Retrospective descriptive statistical analysis of the neurological status, pain, presence of subsidence and bone fusion with the use of PEEK cages in 8 atlantoaxial joints of 4 patients with basilar invagination. All patients were treated with atlantoaxial facet distraction and realignment and subsequent arthrodesis C1-C2 by the technique of Goel modified by the use of PEEK cage. Results: All patients showed improvement in Nurick neurological assessment scale and Visual Analogue Scale (VAS) of pain. There were no cases of subsidence, migration, or damage to the vertebral artery during the insertion of the cage. All joints evolved with bone fusion, assessed by dynamic radiographs, and computed tomography. Two patients developed neuropathic pain in dermatome of C2 and one patient had unilateral vertebral artery injury during C2 instrumentation treated with insertion of pedicle screw to control the bleeding. Conclusion: The results of the treatment of basilar invagination by the Goel technique with the use of PEEK cages shown to be effective and safe although further studies are needed to confirm this use.


RESUMO Objetivo: Análise do uso do implante tipo cage em poli-éter-éter-cetona (PEEK) no realinhamento e distração facetária atlantoaxial da invaginação basilar pela técnica de Goel. Método: Análise estatística descritiva retrospectiva de estado neurológico, dor, presença de fusão óssea e subsidência com o uso do cage em PEEK em 8 articulações atlantoaxiais de 4 pacientes portadores de invaginação basilar, todos tratados com distração, realinhamento atlantoaxial e artrodese posterior C1-C2 pela técnica de Goel, modificada pela utilização do cage em PEEK. Resultados: Todos os pacientes apresentaram melhora na escala de avaliação neurológica de Nurick e na Escala Visual Analógica (EVA) de dor. Não ocorreu caso de subsidência, migração ou dano à artéria vertebral decorrente da colocação do cage. Cem por cento das articulações evoluíram com fusão óssea, avaliada por radiografia dinâmica e tomografia computadorizada. Dois pacientes evoluíram com dor neuropática no dermátomo de C2 e em um paciente houve lesão unilateral da artéria vertebral durante a instrumentação de C2, tratada com inserção do parafuso pedicular para controle do sangramento. Conclusão: Os resultados da redução vertical da invaginação basilar pela técnica de Goel com a utilização de cage em PEEK mostrou ser eficaz e segura, porém ainda são necessários estudos para confirmar essa utilização.


RESUMEN Objetivo: Análisis del uso del implante tipo caja en poli-éter-éter-cetona (PEEK) en el realineamiento y distracción facetaria atlantoaxial de la invaginación basilar por la técnica de Goel. Métodos: Fue realizado un análisis estadístico descriptivo retrospectivo del status neurológico, dolor, presencia de fusión ósea y hundimiento con el uso de la caja en PEEK en 8 articulaciones atlantoaxiales de 4 pacientes que presentaban invaginación basilar, todos tratados con distracción y realineamiento atlantoaxial y artrodesis posterior C1-C2 mediante la técnica de Goel. Resultados: Todos los pacientes presentaron mejoría en la escala de evaluación neurológica de Nurick y en la Escala Visual Analógica (EVA) del dolor. No hubo casos de hundimiento, migración o daño a la arteria vertebral debido a la colocación del implante. El 100% de las articulaciones evolucionaron con fusión ósea evaluada por radiografía dinámica y tomografía computarizada. Dos pacientes evolucionaron con dolor neuropático en el dermatomo de C2, y en un paciente hubo lesión unilateral de la arteria vertebral durante la instrumentación de C2, tratada con inserción de un tornillo pedicular para control del sangrado. Conclusión: Los resultados de la reducción vertical de la invaginación basilar por la técnica de Goel con el uso de caja en PEEK han demostrado ser eficaz y segura pero se necesitan más estudios para confirmar este uso.

ABSTRACT

At the craniocervical junction, developmental anomalies of the axis may produce clinical symptoms by compressing the upper cervical cord during movements of the head and neck. The present study aimed at investigating several varieties and deformities of the axis on skeletal specimens of Eastern Anatolian origin. On 76 specimens, developmental anomalies and the variants of the second vertebrae (axis) were investigated. Hypoplasia of the dens axis in one specimen, the dens axis of a child with a bifid apex in another specimen and an arthrotic formation located on the apex of the dens in six axes were found. A bone protrusion narrowing the transverse foramen was also observed. The types of absence of the dens axis and clinical symptoms that may be caused by them are discussed. It was concluded that the frequency of arthrotic formations might reflect the possibility that the individuals suffered less commonly from neck pain due to arthrotic degeneration

ABSTRACT

A rare case of the complete absence of the posterior elements of C2 is reported. The patient presented with neck pain without any neurological deficits and radiology revealed a mobile, partially reducible dislocation of the C2 over C3 vertebra. A posterior fusion utilizing a contour rod, sublaminar wire fixation, and onlay bone grafts between the occiput and the C3 vertebra was performed for spinal stability.
