Clinical Forum Spinal Deformity: Tips and Tricks Harry L Shufflebarger MD, Miami, FL Vertebral Level Determination during Surgery In any spinal surgery, exact determination of vertebral levels is mandatory. Many methods have been employed to determine what levels are exposed, instrumented, and fused. Anatomic methods have been employed. Identification of the short transverse process on thoracic 11 and the mamillary body of thoracic 12 have been helpful in level determination. The change in facet orientation at the thoracolumbar junction has also been of value. However, these anatomic landmarks are not 100% constant and reliable as determinants of vertebral levels. Radiographic methods have also been used. Usually an instrument (towel clip or Kocher clamp) is placed on a spinous process and a plain radiograph made. This may be difficult to interpret as the spinous process and vertebral body are not always easily identified. And, it takes time to process the radiograph. An infallible method employs image intensification. The C-arm is used in all deformity cases, and is always in the room and draped. The 12th thoracic vertebra (or 11th or 1st lumbar) is tentatively identified. An awl is then placed at the entrance to the pedicle. This area is viewed on AP fluoroscopy. By observing the ribs and the pedicle with the awl, accurate identification of the level is assured, as illustrated below. Juvenile Rheumatoid
Arthritis Case History & Summary of Spinal Manifestations Joseph O’Brien, MD Johns Hopkins University, Baltimore, MD Case History: History and Examination A 15 year-old male presented to the emergency department with a chief complaint of neck pain after sustaining a fall from standing. His past medical history was significant for systemic juvenile rheumatoid arthritis (JRA) diagnosed at age 8. His medical sequalae from JRA included pericarditis, avascular necrosis of his left hip and boutonniere deformity of his digits. On examination, he had posterior midline tenderness, but no neurologic deficits. His reflexes were normal. No pathologic reflexes were present and sensation was normal as well. Radiographic Studies Computed tomography (CT) and magnetic resonance imaging (MRI) of his cervical spine demonstrated atlanto-axial subluxation with rheumatoid panus (figures 1-4). The space available for the spinal cord at C1-C2 was 6mm as measured on CT scan. Extension radiographs showed that the atlanto-axial interval was not reducible (figure 5). Posterior instrumentation and fusion was recommended.
Operative Treatment A standard posterior approach was made to C3-C1. Subperiorsteal dissection was performed using monopolar cautery starting at the lateral mass of C3 and proceeded rosterally to expose the posterior elements of C2 and C1. Bipolar cautery and a Penfield number 1 was then use to expose the arch of C1 1.5 centimeters from midline bilaterally. Dissection along the pars of C2 then proceeded along its medial and superior borders using an irrigating bipolar. After exposure of the pars of C2, attention was directed at exposing the C2 nerve root. Dissection then proceeded under the C2 nerve root using irrigating bipolar cautery until the C1-C2 joint was exposed. Attention was then directed to the inferior border of the C1 arch. Preoperative measurements on the CT scan showed that the center of the lateral mass was 1.2 cm from midline. This roughly corresponded to point where the arch met the inferior portion of the lateral mass. This was palpated with a Penfield number four and irrigating bipolar electrocautery was used to expose the lateral mass of C1. A posterior cervical fusion was performed. X-ray was used to confirm reduction of C1 and C2. The wound was irrigated. Interoperative neuromonitoring showed excellent signals. The patient awoke and was found to be in excellent condition with 5/5 strength in all myotomes. Postoperative CT scans showed excellent reduction. Introduction and Classification Childhood arthritis is the most common chronic disease of childhood3. According to the International League of Associations for Rheumatology (ILAR) criteria, the term juvenile rheumatoid arthritis has given way to juvenile idiopathic arthritis (JIA) as part of a larger classification, which includes ankylosing spondylitis and psoriatic arthritis5. JIA is subclassified according to onset, associated sequalae, and the presence of blood markers (HLA-B27, Rheumatoid Factor). Table 1 lists the subtypes of JRA and JIA. Regardless of classification, one or more joints must be affected for at least 6 weeks with an age of onset less than 16 years for the diagnosis to be made3,5. For the purpose of clarity, JRA will be discussed in this review.
Table 1: Nomenclature for childhood arthritis. RF, rheumatoid factor. Epidemiology JRA is more common in females than males. In a series reported by Hensinger, et al, 69% of the patients were female (1986). The overall incidence of JIA is 5-18/100,000 with a prevalence of 1 per 1,000 children6. Presentation Juvenile rheumatoid arthritis presents on average at 6 years of age1,3. This presentation varies according to the subtype, for instance, pauciarticular patients tend to present at a younger age. In a study of 121 children with JRA, 11% had systemic arthritis, 42% had polyarthritis, and 47% had pauciarticular disease1. The subtypes present differently and have different manifestations of the disease with respect to the spine. Systemic JRA presents with daily spiking fevers and one or more of the following: rash, myalgias, generalized lymphadenopathy, hepatosplenomegaly, and serositis (inflammation of the pleura, pericardium, or peritoneum)3. Joint arthritis may present long after the systemic manifestations of disease. Pauciarticular JRA is the most common subtype. It tends to present earlier (1-4 years of age). Between 1-4 joints will be affected by the disease. Approximately 20% of children will develop anterior uveitis3,6. One should examine the child’s pupils to ensure that they are round. If they are not, referral to ophthalmology should be made. Polyarticular JRA is defined by having 5 or more joints affected within the first 6 months of disease. Uveitis may occur, but at a much lower incidence than pauciarticular JRA6. It is important to note that a large proportion of children with JRA will have disability into adulthood. Approximately half will have active arthritis 10 years after diagnosis6. Up to 17% will require a walking aid. In addition to the appendicular manifestations, many children will develop changes in the spine. Spinal manifestations Involvement of the cervical spine is more common in JRA, while the lumbar spine is involved mostly with ethesiopathy-related arthritides (ankylosing spondylitis)1,3,6. With regard to the cervical spine, Hensinger, et al, described seven characteristic changes.
In the lumbar spine, one may encounter sclerosis of the vertebral corners, loss of disc height, syndesmophyte formation or bony ankylosis (as with ankylosing spondylitis). In children with chronic steroid use, compression fractures or osteopenia may be notable in the thoracic and lumbar spine2. Sacroilitis may be noted as well. Magnetic resonance imaging may show marrow edema and enhancement around the joint space. In summary, JRA is a common disease of childhood. Children presenting to the practicing spine surgeon should have their cervical spine imaged to rule out instability. References: 1. Hensinger R. DeVito P. Ragsdale C.

Shah, MD, AI DuPont Hospital for Children DS: How important is the versatility of a spine system when determining your approach to treating complex spinal pathologies? SS: "Versatility, apart from reliable support from the local sales force and the manufacturer, is probably the single most important feature of a spine system for a surgeon that treats complex spinal pathologies, such as deformity, trauma and tumor. The EXPEDIUMDS: Talk a little bit about design history/lineage, and how that impacts your decision with respect to using a particular spine system? SS: "The EXPEDIUM Spine System, at its foundation, is based on MOSS DS: Oftentimes surgical technique is limited by the capabilities of instrumentation. What has your experience been with the EXPEDIUM Spine System, and do the instruments and implants facilitate your surgical goals? SS: "On the contrary, EXPEDIUM has afforded me possibilities that push the envelope in terms of correction capability of even the most rigid, severe scoliosis. My experience with the system has been a pleasure; there is really no case that I feel will surmount the capabilities of the system. My favorite innovations of the system are the top notch feature, the uniplanar screw and the high strength stainless steel rods. The top notch feature allows the reduction tools to easily capture the screw head and facilitate engagement with the rod. The uniplanar screw accommodates the sagittal plane, but still allows control of the coronal and axial plane for correction and derotation; the derotation instruments attach intuitively to the screw heads and securely transfer corrective forces. The higher strength stainless rods have truly redefined control of severe deformities." DS: What are some of the most common challenges you face intra-operatively when correcting complex deformities, and how has your spine system-of-choice helped you to mitigate these issues? SS: "The most common challenges I face in pediatric spinal deformities are sagittal plane issues in the thoracic spine, correction of pelvic obliquity and small stature patients. In adolescent idiopathic scoliosis, a goal is to restore thoracic kyphosis to the scoliotic spine, which at the apex of the curve may be lordotic; the EXPEDIUM uniplanar screws and high strength rods have been very helpful in this effort. Correction of pelvic obliquity and rigid pelvic fixation in neuromuscular scoliosis, until now has been elusive. The various sacropelvic implant options and pelvic obliquity control apparatus will set the system apart from anything available. Young patients and those with skeletal dysplasias requiring instrumentation pose challenges with implant size and prominence; EXPEDIUM 4.5 mm will offer a superior solution for the small patient with challenging spinal pathology with virtually every implant style and feature in the current EXPEDIUM line.The educational opportunities offered by the company for complex pathology do an excellent job of teaching the newest surgical techniques and proper use of the instrumentation that fill a doctor’s bag with everything needed to treat this spinal pathology. A Look Back – 2007 Educational Events Highlights2007 Pre-Fellowship Bioskills Workshop
In April and May of this year DePuy Spine hosted the 4th annual Pre-Fellowship
Bioskills Workshop. By all accounts this was the most successful year yet! This unique course is designed specifically for the incoming 2007-2008 spine fellows. Participation is limited to fellows who are attending programs that are supported in part by educational grants from DePuy Spine this academic year. During the course, the participants had the chance to learn surgical techniques and anatomic approaches from their fellowship directors and other instructors prior to beginning their fellowship year. The goal of this program is to enhance the participants’ surgical skills and accelerate their progress along the learning curve. This training course is designed to comprehensively cover anterior and posterior approaches to the cervical, thoracic and lumbar spine. This year DePuy Spine contributes to approximately 38 fellowship programs, which include nearly 70 fellows. Given the large number of faculty and participants this workshop was hosted on two different weekends this year. Each course was very well attended, with approximately 19 faculty members and 21 participants in Las Vegas and 22 faculty members and 28 participants in St. Louis. The participants truly appreciated the opportunity to participate in this unique educational opportunity! ![]() A Look Ahead – Upcoming Education / Events

Practice Related Tips & TricksJennifer Beaver, Zupko & AssociatesSurgeon Decoder Kit for EOB’s KarenZupko & Associates, Inc. www.karenzupko.com Surgeons Decoder Kit for EOBs Given the complexity of today’s reimbursement process and ever-changing coding rules it can seem impossible to get paid for services. But surgeons need look no further than the payment/denial notices sent by plans in response to physician claims. These documents, called EOBs – explanation of benefit forms - hold the key to understanding and monitoring payment. What can EOBs tell a surgeon?
KZA recommends surgeons review 15 surgical case EOBs each month; these should include those with payments and those with denials. Fellows and surgeons in private practice should be able to easily request copies of EOBs from the administrator. Those in hospital or academic settings may not be able to obtain the actual hard copy EOB printout, but can often receive a file of the same information listed in a Microsoft
Excel spreadsheet. Physicians in both practice settings will need an introduction
to the information they are reviewing, but that is especially true for those receiving
an electronic file as the headers may not be clear. When reviewing EOBs surgeons should focus on the claim adjustment reason and remittance advice remark (i.e., denial) codes. It is these codes and their definitions which are usually provided at the end of the EOB, that alert surgeons to reimbursement or coding problems. If EOBs do not include a "key" to decipher the codes, they can be referenced at the following website: http://www.wpc-edi.com/codes (click on claim adjustment and remittance advice links and check both lists). Ongoing education is the logical next step in the continuous improvement cycle of coding and reimbursement education. Both NASS and the AANS offer coding courses which review spine coding and reimbursement issues in depth. While the NASS course for the year was offered in March this year, the AANS offered the first advanced course on June 29-30) and the next one is slated for August 24-25, and the introductory course for September 7-8, 2007 (visit http://www.aans.org/education/educational/07coding_courses.asp ). Bonus – NPI Update! In the last issue of Practice Related Tips & Tricks we discussed the importance of obtaining an NPI – national provider identifier – and the fact that delays in deadlines were possible. Although over 2 million NPIs have been issued, some providers and plans were not prepared for the May NPI deadline. In addition, errors in the new CMS 1500, which was to be mandatory at about the same time as the NPI implementation, resulted in concerns about timely claim processing and payment. As a result, CMS and many other plans issued contingency plans which require that claims for services be submitted with BOTH the NPI and the physician’s former provider ID number. Contact your insurance plans to see their requirements, which may or may not mirror CMS requirements. Plans will notify providers when they may begin submitting claims with just the NPI; Medicare notes it may provide such notification as early as July 1, 2007. Remember that individual physicians, as well as private practice groups, must obtain an NPI. Visit https://nppes.cms.hhs.gov to apply for an NPI. In addition, physicians are encouraged to share their NPIs with other physicians and health care entities when requested. CMS has also announced it will create an online searchable database of physician NPIs. DePuy Spine 2nd Annual Clinical Research Paper ChallengeWe are very pleased to announce the launch of the 2nd Annual DePuy Spine Clinical Research Paper Challenge. The goal of this exciting contest is to support and encourage clinical research endeavors that will increase the clinical data available to surgeons and patients, helping to maximize spinal surgeon awareness and patient care.This Challenge is open to all spine surgery fellows currently enrolled in a fellowship program supported in part by DePuy Spine, as well as all spinal surgeons who completed a fellowship program supported in part by DePuy Spine within the last three years. We invite you to take part in this exciting new program.
