Minimally Invasive Spine Surgery in Denver
Dr. Arias runs a robust spine surgery practice in Englewood, specializing in neck and lower back disorders. His approach begins with the most conservative, minimally invasive treatments and avoids spinal fusion whenever possible.
As a Denver Neurosurgeon, he uses advanced motion-preserving techniques such as disc replacement to help patients maintain mobility and recover faster.
Recognized as a Top Doctor in Neurosurgery by Castle Connolly and 5280 Magazine in both 2024 and 2025, Dr. Arias is known for his compassionate approach, surgical precision, and commitment to advancing the field of neurosurgery. His dual training in neurosurgery and endovascular neuroradiology allows him to offer both traditional and minimally invasive treatment options for complex brain and spine conditions.
Dr. Arias is trained as both a neurosurgeon and radiologist and is a recognized specialist in treating brain tumors, including meningiomas, glioblastomas, and pituitary tumors. Using minimally invasive, hair preserving approaches, Dr. Arias can achieve gross total resection of some of the most complex tumors. For appropriate tumors, Dr. Arias can offer Gamma Knife stereotactic radiosurgery, and endoscopic approaches.
Patients with lesions affecting the blood vessels of the brain and neck, such as aneurysms, arteriovenous malformations (AVMs), and carotid stenosis, greatly benefit from Dr. Arias’ sub-specialized training.
Traditionally, neurosurgeons provided open surgery for these lesions, while radiologists were able to present less invasive options by accessing arteries in the patient’s groin or wrist. Dr. Arias trained as both a neurosurgeon and radiologist, so he can provide both options in a single visit, giving an unbiased and comprehensive perspective.
