A spinal dural arteriovenous fistula (DAVF) is a known cause of venous congestive myelopathy. These lesions are thought to be acquired. There exist two prior reports that describe DAVF presenting with slowly progressive myelopathy years after lumbar disc surgery. ⋯ This represents the first case of an occult spinal DAVF becoming acutely symptomatic after lumbar disc surgery. Although the etiology of the lesion and its symptomatic progression remains unknown, an alteration of blood flow through the DAVF as a result of surgery may have resulted in progressive venous congestive myelopathy. The present case highlights the importance of considering a spinal DAVF in the differential diagnosis of any patient with signs of myelopathy or conus medullaris syndrome after lumbar discectomy. In addition, this case underscores the gravity of recognizing subtle features that suggest the presence of an occult vascular malformation on preoperative imaging, as symptomatic progression of these lesions carries significant potential morbidity.

The utilization of motion-preserving implants versus conventional instrumentation systems, which stabilize the operative segments, necessitates improved understanding of their comparative biomechanical properties and optimal biomechanical method for surgical revision. ⋯ The findings highlight a variety of important trends at the operative and adjacent levels. In terms of revision strategies, posterior pedicle screw reconstruction combined with an existing Charité was not found acutely to be statistically different from pedicle screws combined with FRA.

An ideal classification system for thoracolumbar (TL) spine fractures should facilitate communication between treating physicians and guide treatment by means of outlining the natural history of injuries. The classification scheme should also be comprehensive, intuitive, and simple to implement. At the present time, no classification system fully meets these criteria. In this review, the authors attempt to describe the evolution of TL fracture classification systems from their inception to the present day. ⋯ The classification of TL injuries has evolved significantly over the course of the last 75 years. Most of these schemes were limited by their complexity, relevance, and/or poor reliability. The TLISS classification system represents the most recent evolution as it combines several important factors capable of guiding the management of TL injuries. Nonetheless, more research regarding this rating scale remains to be performed.

Chronic back pain is a condition characterized by high rates of disability, health-care service use, and costs. ⋯ Factors other than disability were associated with satisfaction with chronic LBP visits. Understanding the role of medication in satisfaction and its implications for the health behaviors of this highly disabled population may be particularly important.

Large, prominent osteophytes along the anterior aspect of the cervical spine have been reported as a cause of dysphagia. Improvement of swallowing after surgical resection has been reported in a few case reports with short-term follow-up. The current report describes outcomes of a series of five patients with surgical treatment for this rare disorder, with a long-term follow-up. ⋯ Although rarely indicated, surgical resection of anterior cervical osteophytes from DISH causing dyphagia produces good clinical and radiographical outcomes. After thorough evaluation to rule out other intrinsic or extrinsic causes of swallowing difficulty, surgical treatment of this uncommon condition might be considered.
