1259 The Position of the Aorta Relative to the Spine: Is It Mobile or Not?
Geertje C. Huitema, MD; Erwin M. J. Cornips, MD; Martijn H. Castelijns, MD; André van Ooij, MD, PhD; Henk van Santbrink, MD, PhD; Lodewijk W. van Rhijn, MD, PhD
This study is a CT and MRI evaluation of the mobility of the aorta relative to the spine performed in 50 patients. Aorta-vertebral angle and aorta-vertebral distance were evaluated. A substantial difference in the position of the aorta relative to the spine in prone and in supine position was most markedly seen at levels T4 to T8.

1265 Increase of 200-kDa Neurofilament-Immunoreactive Afferents in the Substantia Gelatinosa in Allodynic Rats Induced by Compression of the Dorsal Root Ganglion.
Kazuyuki Watanabe, MD; Shin-ichi Konno, MD, PhD; Miho Sekiguchi, MD, PhD; Nobuhisa Sasaki, MD, PhD; Takashi Honda, MD, PhD; Shin-ichi Kikuchi, MD, PhD
In DRG compression rats, allodynia was demonstrated by decrease of mechanical withdrawal threshold and c-Fos expression in the superficial spinal dorsal horn induced by non-noxious stimulation. In addition, increase of RT97-immunoreactive afferents in the superficial spinal dorsal horn was observed. These changes may be related to allodynia induced by DRG compression.

1272 BDNF, NT-3, and NGF Released From Transplanted Neural Progenitor Cells Promote Corticospinal Axon Growth in Organotypic Cocultures.
Naosuke Kamei, MD, PhD; Nobuhiro Tanaka, MD, PhD; Yosuke Oishi, MD, PhD; Takahiko Hamasaki, MD; Kazuyoshi Nakanishi, MD, PhD; Norio Sakai, MD, PhD; Mitsuo Ochi, MD, PhD
Transplantation of neural progenitor cells promoted axon growth from the brain cortex into the spinal cord in organotypic cocultures. In addition, the axon growth promoted by NPCs was significantly suppressed by the addition of neutralizing antibodies against BDNF, NT-3, and NGF. These findings suggest that BDNF, NT-3, and NGF secreted by transplanted NPCs are involved in the promotion of corticospinal axon growth after transplantation of NPCs.

1279 Association of Gene Polymorphisms With Intervertebral Disc Degeneration and Vertebral Osteophyte Formation.
Yoshihito Sakai, MD; Yukihiro Matsuyama, PhD; Yukiharu Hasegawa, PhD; Hisatake Yoshihara, MD; Hiroshi Nakamura, MD; Yo***o Katayama, MD; Shiro Imagama, MD; Zenya Ito, MD; Naoki Ishiguro, PhD; Nobuyuki Hamajima, PhD
In 387 elderly persons, disc degeneration and osteophyte formation were evaluated. In the polymorphism of alcohol dehydrogenase (ADH2), prevalence of osteophyte formation without disc height narrowing was less in His/Arg and Arg/Arg than His/His. The 47Arg polymorphism in the ADH2 may act to suppress osteophyte formation unaffected by disc degeneration.

1287 Cell Polarity in the Anulus of the Human Intervertebral Disc: Morphologic, Immunocytochemical, and Molecular Evidence.
Helen E. Gruber, PhD; Jane Ingram, BS; Gretchen L. Hoelscher, MS; H James Norton, PhD; Edward N. Hanley Jr, MD
The specialized lamellar anulus organization implies directed secretion of extracellular matrix components by polarized disc cells. Morphologic, immunocytochemical, and molecular evidence for expression of the polarity-related genes PAR3, PAR6, and claudin-1 and -11 by disc cells is presented. Findings advance our knowledge of anulus cell function in creating a tissue-specific extracellular matrix.

1295 The Presence of Pleiotrophin in the Human Intervertebral Disc Is Associated With Increased Vascularization: An Immunohistologic Study.
William E. B. Johnson, PhD; Angela M. Patterson, PhD; Stephen M. Eisenstein, FRCS, PhD; Sally Roberts, PhD
The human intervertebral disc is largely avascular but is invaded by blood vessels (sometimes accompanied by nerves) as it degenerates or following prolapse. We show here that the presence of pleiotrophin, a potentially angiogenic and neurotrophic cytokine, is associated with the extent to which pathologic human intervertebral discs are vascularized.

1303 Recombinant Human Osteogenic Protein-1 Upregulates Proteoglycan Metabolism of Human Anulus Fibrosus and Nucleus Pulposus Cells.
Yoshiyuki Imai, MD, PhD; Kei Miyamoto, MD, PhD; Howard S. An, MD; Eugene J.-M. A. Thonar, PhD; Gunnar B. J. Andersson, MD, PhD; Koichi Masuda, MD
Recombinant human osteogenic protein-1 is effective in stimulating the cell proliferation and proteoglycan metabolism by human intervertebral disc cells cultured in alginate beads. These effects were confirmed in disc cells obtained from individuals of widely varying ages. Recombinant human osteogenic protein-1 may prove useful for the biologic repair of the intervertebral disc.

1311 Multidirectional Testing of One- and Two-Level ProDisc-L Versus Simulated Fusions.
Manohar Panjabi, PhD; Gweneth Henderson, BASc; Celeste Abjornson, PhD; James Yue, MD
One- and 2-level ProDisc-L were compared with the corresponding simulated fusions in flexion-extension, and bilateral lateral bending and torsion, using the Hybrid test method. ProDisc-L caused no significant increases in rotations at the nonoperated levels, while the simulated fusions did.

1320 Preliminary Study on Biomechanics of Vertebroplasty: A Computational Fluid Dynamics and Solid Mechanics Combined Approach.
Jeremy Teo, MEng; Shih Chang Wang, FRANZCR; Swee Hin Teoh, PhD
This paper describes a technique that can develop patient-specific finite element models. These models are capable of intraosseous PMMA cement flow visualization using computational fluid dynamics. The subsequent export of PMMA distribution for postvertebroplasty stress-strain analyses is also possible for in-depth parametric studies.

1329 Influence of Pain Distribution on Gait Characteristics in Patients With Low Back Pain: Part 1: Vertical Ground Reaction Force.
C Ellen Lee, PhD, PT; Maureen J. Simmonds, PhD, PT; Bruce R. Etnyre, PhD, PT; G Stephen Morris, PhD, PT
Pain distribution of people with low back problems differentially influences the vertical ground reaction force they experience during walking. People with referred leg pain and those with back pain only experience variable and different amount of vertical ground reaction force than their pain-free counterparts depending on the walking speed condition.

1337 Superiority of Multilevel Cervical Arthroplasty Outcomes Versus Single-Level Outcomes: 229 Consecutive PCM Prostheses.
Luiz Pimenta, MD; Paul C. McAfee, MD; Andy Cappuccino, MD; Bryan W. Cunningham, MSc; Roberto Diaz, MD; Etevaldo Coutinho, MD
This prospective study of cervical arthroplasty is the first report showing significantly improved clinical outcomes for multilevel cervical arthroplasty compared with single-level cervical total disc replacement using an FDA-validated outcome instrument. This compares favorably with multilevel fusions, which consistently show deteriorating outcomes as the number of levels of treatment increases.

Marie Beauséjour, MASc; Marjolaine Roy-Beaudry, MSc; Lise Goulet, MD, PhD; Hubert Labelle, MD
We compared the current referral patterns in orthopedics with those documented before discontinuation of school scoliosis screening programs. The current case-mix is displaying lack of appropriateness with 42% of suspected cases considered as inappropriate referrals and 32% of confirmed adolescent idiopathic scoliosis patients referred late with regards to brace treatment indications.

1355 Analysis of Sagittal Alignment in Thoracic and Thoracolumbar Curves in Adolescent Idiopathic Scoliosis: How Do These Two Curve Types Differ?
Vidyadhar V. Upasani, MD; John Tis, MD; Tracey Bastrom, MA; Jeff Pawelek, BS; Michelle Marks, PT, MA; Baron Lonner, MD; Alvin Crawford, MD; Peter O. Newton, MD
An analysis of pelvic parameters and sagittal alignment, comparing patients with thoracic curves (Lenke 1A, B), patients with thoracolumbar curves (Lenke 5), and normal adolescents, demonstrated an increased pelvic incidence in patients with adolescent idiopathic scoliosis and different patterns of sagittal alignment for the 2 curve types.

1360 Sex Differences in Consequences of Musculoskeletal Pain.
Hanneke A. H. Wijnhoven, PhD; Henrica C. W. de Vet, PhD; H Susan J. Picavet, PhD
Women with any musculoskeletal pain report more healthcare use for musculoskeletal pain, while men report more work disability (ever in life) due to low back pain. These sex differences cannot be explained by general risk factors, but associations between these factors and consequences of musculoskeletal pain show some sex differences.

E348 The Position of the Aorta Relative to the Spine in Patients With Left Thoracic Scoliosis: A Comparison With Normal Patients.
Todd A. Milbrandt, MD, MS; Daniel J. Sucato, MD, MS
The position of the aorta in left-sided scoliosis is in the concavity but in a relative safe position; in the larger left-sided-scoliosis, the aorta is in a more dangerous position for laterally malpositioned pedicle screws and directly in-line with the tip of anterior vertebral body screws.

E358 Combined Extraforaminal and Intradiscal Cement Leakage Following Percutaneous Vertebroplasty.
Jung-Kuei Chen, MD; Hung-Maan Lee, MD; Jui-Tien Shih, MD; Sheng-Tsai Hung, MD
This work describes the first case of radiculopathy and severe low back pain following percutaneous vertebroplasty with polymethylmethacrylate. Radiographs showed extraforaminal and intradiscal cement leakage in different vertebral levels resulting in compression of nerve root and acute adjacent compression fracture. Motor and sensory deficits were relieved after surgical intervention.
