Congratulations to Rick Sasso, MD, a spine surgeon with Indiana Spine Group, who was just awarded his eighth patent!  This is patent number 7,727,266 for a method and apparatus for retaining screws in a plate.  
 

This patent is for an anterior cervical plate, now called Venture.  This plate is used in spine surgery for patients suffering from a herniated disc or stenosis (disc degeneration), or after trauma, tumors or other conditions causing neck instability.  The plate is used to stabilize the cervical spine after removing the disc. 

Below is an abstract of this patent:

A retention system for maintaining a screw to a vertebral plate. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture. A method of using the system is also included and comprises positioning the ring within a cavity in the plate, maintaining the position of the ring to the plate by attaching a cap, inserting a screw through the aperture and attaching the plate to a vertebral member, and positioning the ring over the screw head and preventing the screw from backing-out.

The Nutritionally Healthy Spine – This continuing medical education session, presented by Lori Petrie, RD, will continue to focus on a healthy spine and the importance of nutrition in achieving and maintaining a healthy spine. This session will provide important nutritional recommendations for a healthy spine.  In addition to diet and lifestyle other factors that will be addressed for a healthy spine will include popular over-the-count medications, and a review of herbal, vitamin and nutritional supplements. Ms. Petrie is an outpatient nutritional counselor with St.Vincent Hospital.

Back Pain | Chronic and Failed – It is estimated that approximately 40% of individuals that undergo back surgery continue to have back pain.  Jonathan Gentile, MD, a minimally invasive spine specialist with Indiana Spine Group will address this ongoing issue.  In this educational session he will address both chronic back pain and failed back syndrome and will discuss the differentiation factors, and the diagnostic perils.  Additionally, Dr. Gentile will discuss the treatment options, indications and patient selection for various treatment options.  One treatment option that will be highlighted will included the spinal cord stimulator, used as an option for failed back syndrome.

Following the educational tracks for Indiana Spine Group’s annual continuing medical education symposium Back Talk, we will then feature the keynote speaker. As previously blogged, our keynote speaker joins us from Salt Lake City, Utah. James McGreevy, MD, is a trauma surgeon and Professor of Surgery at the University of Utah Medical Center and Chief of Surgery for the Salt Lake City VA Medical Center. Additionally, he is a Colonel in the United States Air Force Reserve and the Commander of the 419^th Medical Squadron.

During Dr. McGreevy’s keynote address he will discuss medicine on the front lines – as he talks about his experiences in Iraq. A few things that will be discussed include the operations of the Balad Air Force Theater Hospital, the level of trauma care available to wounded military personnel and civilians. Additionally, he will discuss the common occupational health hazards associated with fighter types of operations in a deployed environment. 

Dr. McGreevy was deployed in 2005 and 2007, and has served as a flight surgeon in Balad at the Balad Air Force Theater Hospital. This is one of the largest U.S. military hospitals in Balad, a multi-specialty trauma hospital that treats soldiers, military personnel, civilians and sometimes insurgents.

Recently Rick Sasso, M.D., a spine surgeon with Indiana Spine Group,
co-authored a book chapter for a medical textbook. This chapter was titled “Anterior Lumbar Interbody Fusion.”  Anterior lumbar interbody fusion, usually referred to as ALIF, is a spine surgical procedure commonly used to treat discogenic low back pain - when non-operative measures are ineffective.

In this chapter, the historical background of anterior lumbar interbody fusion was reviewed. This spine surgery procedure was used as early as 1932 for the treatment of spondylolisthesis. Additionally, this chapter reviewed the biomechanics, patient selection, clinical studies, and imaging. To read this chapter, click here

One spine surgery research study that I participated in - compared the post-operative results of cervical arthroplasty and arthrodesis on approximately 500 patients. The objective of this study was to compare any side effects of patients undergoing a cervical arthroplasty with the implantation of a Bryan Cervical Artificial Disc to those patients that underwent a spinal fusion.

In this study, of which there were 31 institutions where patients underwent spine surgery, there were 242 patients who received the Bryan Cervical Artificial Disc and 221 patients that underwent cervical discectomy and spinal fusion. Patients that participated in this study were over 21 years of age, had single level cervical degenerative disc disease causing radiculopathy or myelopathy as well as a few other clinical indicators. Once identified, these patients were evaluated before spine surgery and post-operatively at regular intervals beginning one and one half months following spine surgery up to 2 years. 

This study concluded that both procedures are safe, and that there is not a significant difference in adverse effects with the newer arthroplasty procedure utilizing the Bryan Cervical Artificial Disc when compared to the traditional surgical option of spinal fusion.

In July 2009, an article that Dr. Kenneth Renkens co-authored was published in the Journal of the American College of Surgeons. This article was entitled “A Phase 3b, Open-Label, Single-Group Immunogenicity and Safety Study of Topical Recombinant Thrombin in Surgical Hemostatis”.

This study evaluated the affects of a topical hemostat during surgery. (Note:  a topic hemostat is used to control bleeding during spine surgery and other surgical procedures).   For an abstract of this study background and conclusions, link here. 

Dr. Kenneth Renkens is a neurosurgical spine surgeon with Indiana Spine Group. 

In May 2009, the Bryan Cervical Artificial Disc received FDA approval.  This approval was previously written about in Dr. Sasso’s blog.  The cervical artificial disc provides an alternative spine surgical treatment for cervical degenerative disc disease.

Dr. Rick Sasso, a spine surgeon with Indiana Spine Group, has been a principal investigator in the studies with this spine surgical device – the Bryan Cervical Disc.  A few of abstracts of his published research studies regarding the cervical disc are available on the U.S. National Library of Medicine / National Institutes of Health web site. 

These include:

• Cervical kinematics after spinal fusion and bryan disc arthroplasty 
  
• Motion analysis of bryan cervical disc arthroplasty versus anterior discectomy and spinal fusion: results from a prospective, randomized, multicenter, clinical trial 
  

Often time’s patients that have idiopathic scoliosis may also have a visible rib deformity that may be present following corrective spine surgery.  The traditional spine surgical procedure to correct this has been open thoracoplasty.  A newer, minimally invasive procedure used is video- assisted thoracoplasty.  This procedure is less invasive than the traditional spine surgical procedure.

The last few spine wellness blog entries have discussed the effects of smoking and the spine.  For example smoking can increase your risk for lower back pain, increasing healing time following spine surgery and increase your risk for osteoporosis. 

For a spine wellness fact sheet about smoking and your spine's wellness, click here.

Many times with scoliosis - no treatment is needed.  Once a patient is diagnosed with scoliosis it is important to observe and monitor the curve during the patient’s growing years.  Factors that affect what type of treatment is recommended include the age of the patient and how much growth they have left, the degree and pattern of the curve, and the type of scoliosis. 

Treatment options may range from observation to surgery.  If it is decided that the patient will be observed; they will be evaluated approximately every six months while the patient is still growing.  At this time, the degree of the curve will be assessed.

Bracing is a treatment option to prevent the curve from progressing.  This is recommended if the patient has an idiopathic curve, is still growing and:

• Has a curve greater than 25 degrees,
• Has two more years of potential growth remaining and the curve is between 20 and 29 degrees, (and if female has not had her first menstrual period) or
• Has a curve that is between 20 and 29 degrees and is progressing.   

This spine wellness blog entry will address more about the effects of smoking and your spine’s health.  In this Spine Universe article, it summarizes the negative effects of smoking and its impact on the spine surgery procedure of spinal fusions. 

A general definition of a spinal fusion is that it is a spine surgical procedure that joins bony segments of the spine (vertebrae) – this spine surgery can be performed at the lumbar, thoracic or cervical areas of the spine.  As a part of the healing / fusion process of this spine ssurgery there needs to be new bone growth.  Many factors can affect the success of a spinal fusion and can include the patient’s overall health, other medical conditions and smoking. Research has shown that habitual cigarette smoking results in less successful spinal fusions when compared to similar spine surgical procedures performed on nonsmokers.  Additionally, another study indicated that individuals that smoked had a higher post-operative infection rate than nonsmokers. 

Earlier this year, Dr. Rick Sasso and I were asked to write a spine continuing education chapter on “Controversies in Cervical Spine Surgery”, specifically about a newer spine surgical technology known as dynamic plating for cervical fusions.  Traditional plates, known as static plates, have a high success rate, but in reviewing the published reports of direct comparisons between the two plates, the dynamic plates have a slightly higher percentage which fuse.  It may be even more beneficial in longer fusions.

I have switched my practice to essentially using only the dynamic plates for cervical spinal fusions.  I have been very happy with the  results.  As with all new technology, it is important to carefully monitor results and compare them against established techniques.  I'm keeping an eye on continuing trials even as I incorporate this technology into my own practice.

In October, I was a faculty member at the 8^th Annual Symposium on “Innovative Techniques in Spine Surgery.” This continuing education meeting, hosted in Phoenix, addressed the innovative and emerging technologies of spinal surgery including; arthroplasty, minimally invasive procedures, motion sparring technologies and biologics.  At this meeting I gave a talk on Lumbar Artificial Disc Replacement, and presented the results of the FDA studies for the Cervical Artificial Disc.

This education program was sponsored by the Organization of Spinal Teaching and Research.  The purpose of this group is to facilitate education and discussion among spine care providers and industry and this organization includes leaders in the field of spine surgery and technology that utilize the most advanced and effective technology available for the treatment of spinal disorders.

When an individual continues to have chronic back pain and/or leg pain following back surgery; it is referred to as failed back syndrome. A few treatments for this can include physical therapy or non-steroidal anti-inflammatory medications (NSAID). If medical management is ineffective another treatment option available is a spinal cord stimulator.

A spinal cord stimulator is an implantable device that uses an electrical current to provide a tingling sensation that helps to mask the chronic pain. Dr. Gentile describes it as “a kind of pacemaker for pain.”

In this video, Dr. Gentile describes the procedure for implanting a spinal cord stimulator. Dr. Jonathan Gentile is a minimally invasive spine specialist with Indiana Spine Group.

This procedure is available at Indiana Spine Group. For more information, call 317.228.7000 or toll-free 866.947.7463.
