hérnia de disco

INTRODUCCIÓN: Los cambios en el ligamento flavum (LF) relacionados con la degeneración son secundarios al proceso de envejecimiento o a la inestabilidad mecánica. Estudios anteriores han indicado que LF con envejecimiento muestra pérdida de fibras elásticas y aumento del contenido de colágeno, la pérdida de elasticidad puede hacer que el LF se pliegue en el canal espinal, disminuyendo su espacio. MATERIAL Y MÉTODOS: Se incluyeron 67 pacientes operados de estenosis lumbar espinal (LSS), hernia de disco lumbar (LDH) y espondilolistesis degenerativa (LDS)...

INTRODUCTION: Dynamic magnetic resonance imaging (dMR) is useful to evaluate the unstable cervical spine; it evaluates soft components of the cervical spine and dynamic cervical movements. OBJECTIVE: To describe and analyze the frequency of presentation of herniated discs with static MRI and compare with dMR. METHOD: During December 2014 to February 2016, patients with cervicalgia and suspected cervical instability were evaluated. An observational, descriptive, cross-sectional study was performed, where images obtained in flexion and extension were analyzed using a device compatible with MRI...

Surgical nerve root decompression is rarely needed in the treatment of cervicobrachial neuralgia. In patients with prolonged and resistant pain or neurological deficits, or when signs of associated spinal cord suffering have been found, various surgical procedures can be used, but is most cases the disco-arthro-radicular conflict can be solved by the anterior approach with or without bone graft. This review of long-term résults in a series of 122 patients operated upon and re-examined more than 3 years later shows that the radicular symptoms were relieved in 95% of the cases...
