Press Release

Dr. Jatana Returns to Denver Spine Surgeons

I am pleased to announce that I will be returning to Denver Spine Surgeons in October. I value the support and understanding that I have received during my absence and want to thank everyone for their patience during this time.

After a lot of thought I have come to the decision that upon my return, I will be restructuring my practice. I have decided to shift the focus of my practice to specializing in the treatment of the cervical spine. The treatment of cervical spine ailments has always been my passion and I feel that this is where my attention should be focused. I will be scheduling new and established patients that require evaluations and surgical consultations for their cervical spine issues beginning October 9, 2017. 

With regard to my prior patients that were being treated for their lumbar spine, I realize this change may be difficult and I hope to make this transition in care as smooth as possible for you. So I am pleased to let you know that Dr. Okezie Aguwa has recently joined Denver Spine Surgeons and will be available for consultation.

New study: Denver Spine Surgeons Begin Enrollment in United States Stem Cell Therapy Study

Denver Spine Surgeons announced that it has enrolled its first patient in a nationwide FDA- cleared adult stem cell study testing novel treatment for chronic low back pain. The study will test the use of Mesenchymal Precursor Cells (MPCs) – adult stem cells derived from bone marrow that will be directly injected into the lumbar disc.

Minimally invasive spine surgery effective for many indications, but difficult to learn

Techniques and procedures for minimally invasive surgery of the spine have developed considerably in recent decades and have since become more popular among spine surgeons, in some cases even more so than the traditional open approaches, according to sources who spoke with Spine Surgery Today.

Gary Ghiselli, MD, said he finds minimally invasive surgery (MIS) of the spine more cost-effective than open surgery. It does more to address the quality of life for patients during the immediate recovery period, “as well as the long-term viability of the muscles and tissues overlying the spine,” he said.
