Existing studies suggest a relatively high incidence of dysphagia after anterior cervical decompression and fusion (ACDF). The majority of these studies, however, are retrospective in nature and lack a control group.
Odontoid fractures are the most common odontoid injury and often cause atlantoaxial instability. Reports on postoperative status of patients who underwent surgery for such injuries are limited to small case series, and it is unclear whether any one technique produces better outcomes than another.
Spinal cord injury (SCI) is a devastating event often resulting in permanent neurologic deficit. Research has revealed an understanding of mechanisms that occur after the primary injury and contribute to functional loss. By targeting these secondary mechanisms of injury, clinicians may be able to offer improved recovery after SCI.
Cervical spondylotic myelopathy is increasingly prevalent in the elderly and is the leading cause of spinal cord dysfunction in this population. Laminectomy with fusion and laminoplasty halt progression of myelopathy in these patients; however, both procedures have well-documented complications and associated morbidity and it is unclear which might be most advantageous.
Anterior cervical discectomy and fusion (ACDF) represent the standard treatment for cervical spondylolytic radiculopathy and myelopathy. To achieve solid fusion, appropriate compressive loading of the graft and stability are essential. Fusion may lead to adjacent segment degeneration. Artificial discs have been introduced as motion-preserving devices to reduce the risk of fusion-related complications.
Patients With Cervical Metastasis and Neoplastic Pachymeningitis are Less Likely to Improve Neurologically After Surgery
Although many patients with cervical spine metastases are treated surgically, it is unknown whether certain subsets achieve better pain relief and improvement of neurologic function.
The Cloward anterior interbody fusion is commonly performed for cervical disc herniation or spondylosis. In followup studies, various authors have noted clinically relevant adjacent-level degeneration. However, factors associated with adjacent-level degeneration are not well known.
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.
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.
