Description of Research Interests/Activities

Dr. Ortiz's research interests are primarily in the field of percutaneous diagnostic and therapeutic spine interventions. He is currently participating in several clinical research trials that are assessing new and novel approaches towards the treatment of painful osteoporotic vertebral compression fractures. Other topics of interest include pathologic vertebral compression fractures with application of local therapies such as radiofrequency ablation and coblation. Other topics of interest and activity include: treatments such as percutaenous lumbar decompression
2. treatment of sacroiliac joint pain with radiofrequency neurolysis
3. disc interventions such as percutaneous discectomy
4. facet joint syndrome
5. discography and functional anesthetic discography
6. Radiation exposure during percutaneous spine interventions
