A New Zero-profile Implant for Stand-alone Anterior Cervical Interbody Fusion

M. Scholz MD, K. J. Schnake MD, A. Pingel MD, R. Hoffmann MD, F. Kandziora MD

Several studies suggest fusion rates are higher with anterior cervical discectomy and fusion procedures if supplemented with a plate. However, plates may be associated with higher postoperative morbidity and higher rates of dysphagia. This led to the development of a cervical stand-alone cage with integrated fixation for zero-profile segmental stabilization.

Neurocentral Synchondrosis Screws to Create and Correct Experimental Deformity: A Pilot Study

Hong Zhang MD, Daniel J. Sucato MD, MS

Unilateral pedicle screw epiphysiodesis of the neurocentral synchondrosis (NCS) can produce asymmetric growth of the synchondrosis to create scoliosis in an immature animal model.

The Development and Evaluation of the Subaxial Injury Classification Scoring System for Cervical Spine Trauma

Peter G. Whang MD, Alpesh A. Patel MD, Alexander R. Vaccaro MD, PhD

Fractures and dislocations of the subaxial cervical spine may give rise to devastating consequences. Previous algorithms for describing cervical trauma largely depend on retrospective reconstructions of injury mechanism and utilize nonspecific terminology which thus diminish their clinical relevance add to the difficulty of educating doctors and performing prospective research.

Does Smoking Influence Fusion Rates in Posterior Cervical Arthrodesis With Lateral Mass Instrumentation?

Jason David Eubanks MD, Steven W. Thorpe MD, Vinay K. Cheruvu MSc, MS, Brett A. Braly MD, James D. Kang MD

Smoking is associated with reduced fusion rates after anterior cervical decompression and arthrodesis procedures. Posterior cervical arthrodesis procedures are believed to have a higher fusion rate than anterior procedures.

Percutaneous Vertebroplasty Relieves Pain in Metastatic Cervical Fractures

S. Masala MD, G. C. Anselmetti MD, M. Muto MD, M. Mammucari MD, T. Volpi MD, G. Simonetti MD

Percutaneous vertebroplasty is currently an alternative for treating vertebral fractures of the thoracic and lumbar spine, providing both pain control and vertebral stabilization. In the cervical spine, however, percutaneous vertebroplasty is technically challenging because of the complex anatomy of this region.

Increased In-hospital Complications After Primary Posterior versus Primary Anterior Cervical Fusion

Stavros G. Memtsoudis MD, PhD, Alexander Hughes MD, Yan Ma PhD, Ya Lin Chiu MS, Andrew A. Sama MD, Federico P. Girardi MD

Although anterior (ACDF) and posterior cervical fusion (PCDF) are relatively common procedures and both are associated with certain complications, the relative frequency and severity of these complications is unclear. Since for some patients either approach might be reasonable it is important to know the relative perioperative risks for decision-making.

An Observational Study of Patient-rated Outcome After Atlantoaxial Fusion in Patients With Rheumatoid Arthritis and Osteoarthritis

Dieter Grob MD, Andrea Luca MD, Anne F. Mannion BSc, PhD

Fusion is used to address several types of abnormality of the atlantoaxial segment. Traditionally, outcome has been assessed by achieving solid bony union. Recently, however, patient-rated outcome instruments have been increasingly used, although these may be influenced by concomitant comorbidity.

CT Angiography for Anterior Lumbar Spine Access: High Radiation Exposure and Low Clinical Relevance

Michaela Gstöttner MD, Bernhard Glodny MD, Johannes Petersen MD, Martin Thaler MD, Christian Michael Bach MD

Some spine surgeons perform CT angiography for detailed planning of anterior access to the lumbar spine. However, the value of this imaging method and its influence on surgeons’ decisions are unclear.

RUNX2 Polymorphisms Associated with OPLL and OLF in the Han Population

Yang Liu MD, Yongfei Zhao MD, Yu Chen MD, Guodong Shi MD, Wen Yuan MD

Runt-related transcription factor 2 (RUNX2), BMP-2, COL6A1, and VDR are four genes that may be related to ossification of the spinal ligament. However, their pathogenetic relevance remains unclear. Most cases of ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF) have been reported in Asian populations, but the polymorphic loci in these genes may vary among people of different races.

Case Reports: Painful Limbs/Moving Extremities: Report of Two Cases

Tsuyoshi Miyakawa MD, Mitsunori Yoshimoto MD, Tsuneo Takebayashi MD, Toshihiko Yamashita MD

Painful limbs/moving extremities is a relatively rare condition characterized by aching pain in one limb and involuntary movement in the affected fingers or toes. Its pathomechanism is unknown. We report two patients with painful limbs/moving extremities. In one patient with a painful arm and moving fingers, the symptoms were resolved after surgery.
