RESUMO
Since its inception, medical training and practice are based primarily on the clinical experience provided by the mentors of each of the medical schools. In the 1990s, the first steps were taken for the construction of what we now know as evidence-based medicine. Evidence-based medicine is the set of studies, methods, and principles for the prevention of medical diseases, management guidelines, and algorithms used in sources of evidence. Neurosurgery based on evidence has emerged thanks to advances in neuroscience and information technology that allows the globalization of current scientific information. The results of important reviews on the levels of evidence in neurosurgery are low in percentages of high-quality evidence in this field of medicine. Based on the above, the aim of this manuscript was to describe the application of evidence in neurosurgery, the current state of the art in evidence-based medicine, and the steps needed to create evidence of the best quality in neurosurgery.

El condrosarcoma ocupa el tercer puesto dentro de las neoplasias óseas primarias, siendo la columna vertebral una localización inusual. Según su etiología se clasifican en condrosarcoma primario o secundario a lesiones subyacentes de tipo cartilaginosa como el encondroma u osteocondroma; siendo entre el 80-90% de bajo grado. Pueden presentarse en cualquier nivel de la columna vertebral, siendo más frecuente en la región torácica y cervical, comprometiendo los elementos posteriores de la vértebra, los cuerpos vertebrales o ambos, en un 40%, 15% y 45% respectivamente. El síntoma más común es el dolor localizado asociado a manifestaciones neurológicas. El método diagnóstico de elección es la biopsia por punción y el tratamiento se basa fundamentalmente en la resección quirúrgica
Chondrosarcoma occupies the third position within the primary bony neoplasia's, with an unusual location at the level of the spine. According to their etiology, they are classified as primary chondrosarcoma or secondary to underlying cartilaginous lesions such as the enchondroma or osteochondroma, being between 80-90% of low grade. They can occur at any level of the spine, being more frequent in the thoracic and cervical region, compromising the posterior elements of the vertebra, the vertebral body or both, by 40%, 15% and 45% respectively. The most common symptom is localized pain associated with neurological manifestations. The diagnostic method of choice is biopsy and treatment is based primarily on surgical resection.

Resumen La exposición repetitiva a traumas craneales es una de las características de la encefalopatía traumática crónica. Neuropatológicamente en esta patología encontramos depósitos de proteína hiperfosforilada tau (p-tau). Inicialmente fue descrita como demencia pugilística, pero se ha asociado a otros tipos de deportes, traumas por explosión entre otros. Los síntomas de esta enfermedad incluyen pérdida de memoria, alteración cognitiva, cambios de ánimo y demencia. Presentamos una revisión de la literatura sobre esta interesante enfermedad.
Abstract Repetitive exposure to cranial trauma is one of the hallmarks of chronic traumatic encephalopathy. Neuropathologically, hyperphosphorylated protein tau (p-tau) deposits are found. Initially it was described as pugilistic dementia, but it has been associated with other types of sports, explosive traumas among others. Symptoms of this disease include memory loss, cognitive impairment, mood swings and dementia. We present a review of the literature on this interesting disease.
