Is Intraoperative CT of Posterior Cervical Spine Instrumentation Cost-effective and Does It Reduce Complications?
Symptomatic multilevel cervical myelopathy is often addressed using posterior decompression using two-dimensional fluoroscopy. Intraoperative three-dimensional fluoroscopy provides more accurate information on the position of instrumentation to prevent screw-related complications.
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.
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
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?
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 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.
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
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.
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.
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.
