Free Community Lecture in Colorado Springs

For about 11 million Americans, involuntary tremors are a constant problem that can interfere with just about everything…getting dressed, drinking a cup of coffee or using a cell phone.  This trembling can be caused by Parkinson’s disease and Essential Tremor, a benign often inherited condition.  Dr. Kara Beasley will discuss the latest information and advancements in deep brain stimulation therapy for tremor control.  To RSVP email:  or by calling Sarah at 303-938-5720.

Case Study Published

The World Neurosurgery Journal published a case study by Boulder Neurosurgical & Spine Associates (BNA) surgeons, Sharad Rajpal, MD, and Andrew Bauer, MD, BNA Director of Clinical Research, Sigita Burneikiene, MD, Boulder Community Health pathologist Robert C. Forsythe, MD, and Justin Parker Neurological Institute intern, Colson Tomberlin titled, “Chiari Malformation and Hydrocephalus Masking Neurocysticercosis.”  The report reviewed a case of a 55-year-old Hispanic man who underwent a Chiari decompression surgery, which was complicated with hydrocephalus.  Despite a ventriculoperitoneal shunt placement, he continued to have headaches and was soon found to have several skull base subarachnoid lesions, which were later diagnosed as the sequelae of an active neurocysticercosis infection. The paper highlights the importance of overlapping symptoms between diseases in a short temporal context.

First Surgery in Colorado for New FDA-Controlled Clinical Trial

Alan Villavicencio, MD performed the first surgical case for an FDA-controlled clinical trial to evaluate the LimiFlex™ Paraspinous Tension Band (Empirical Spine Inc., San Carlos, CA) for the treatment of degenerative spondylolisthesis with spinal stenosis. The surgery was performed on  December 12th, at Boulder Community Health.  Boulder Neurosurgical and Spine Associates is one of the study centers in the US participating in the study and the only approved site in Colorado for this procedure.  “Being at the forefront of new surgical techniques is an important part of our practice.  Participating in trials for investigational devices, allows us to bring the most advanced technology options to our patients, helping them return to their lives pain-free,” Alan Villavicencio, MD

The device is being studied as an alternative to the fusion procedure for the treatment of degenerative lumbar spondylolisthesis with stenosis, in which a vertebra has moved forward in relation to the vertebra below and the spinal canal narrows putting pressure on the spinal cord and nerves. The patient symptoms usually consist of low back and leg pain, numbness or weakness in the legs.

“The surgery is minimally-invasive and can be done through a small incision on the patients back.  The procedure took less than 2 hours and went extremely well: the patient left the hospital after only a few hours after surgery with her longstanding symptoms completely resolved.  We anticipate the patient to quickly return to her daily activities, including a planned family trip later this month to the Bahamas,” Alan Villavicencio, MD.

All patients with degenerative spondylolisthesis with lumbar spinal stenosis who are enrolled in the LimiFlex™ study will receive microsurgical decompression, a minimally invasive procedure in which the surgeon will remove bone and soft tissue, which are compressing nerves and causing symptoms. LimiFlex™ will be used to restore the range of motion and stabilize the spine at the level of decompression without the need to use pedicle screw fixation system.
