In Chronic Smoker the mineral deficient vertebrae with reduced bone blood supply facilitate the fail in bone fusion, traumatic vertebral injury and degenerative bone process.

A recent extensive review of the results of conventional percutaneous thermo-coagulation indicated that it is the most effective percutaneous technique with the highest residual morbidity. The present communication is the summary, results and recommendations of our original method, designed to minimize unnecessary morbidity of the procedure. It is based on 31 years of experience in 370 procedures, most of the last 167 performed with our method and technique.

Extraforaminal herniated disc have a relative frequency of presentation and are not described in our setting because they are probably not suspected. Magnetic resonance imaging is the test with the lowest risk of false negatives. In cases of suspicion, where they do not differ from the psoas muscle, tomography with discography should be performed. The paramedian and microsurgical approach is an excellent technique, with better advantages than the medial way.

In the treatment of sciatica due to lumbar disc herniation, multiple surgical techniques have been used, from the traditional open surgeries to remove part of the intervertebral disc for decompress and reduce the pressure of this on the root, until its evolution into smaller incisions that allow decompression using the surgical microscope or through the use of endoscopy to access the disc. In some patients, however, even less invasive methods may be used for decompression.

The relationship between encephalocranial trauma and traumatic epilepsy has been known since the time of Hippocrates (460-357 BC), who in his treatise 'Cranial Trauma' observed that a wound in the left temporal region of the skull produced convulsive seizures in the right hemisphere and viceversa. With industrialization and particularly with the advent of motorized vehicles, residences with different levels of height and unprotected and violent sports practices, the number of cranioencephalic injuries and traumatic epilepsy has increased alarmingly.
