Case Reports
Neurogenic claudication and radiculopathy as delayed presentations of retained spinal bullet.
Firearm injuries to the spine may cause injury to the neurological structures and/or to the spine, including ligaments and bones. ⋯ These cases illustrate that retained intraspinal bullets can present with delayed neurological findings secondary to reactive changes around the bullet.

From a biomechanical perspective, the successful outcome of total disc replacement is largely based on the mechanisms of acute fixation obtained at the index procedure and the extent of porous biological osseointegration at the prosthesis-bone interface, ensuring long-term device fixation. ⋯ The present study represents the largest analysis to date of any retrieved porous ingrowth disc replacement prostheses. A trend was observed of increase porous osseointegration with improved implant positioning; however, the small sample size and high standard deviations account for lack of statistical significance. Although osseointegration occurs despite nonideal intraoperative positioning, it remains imperative that surgeons strive for Ideal implant position.

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.

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.
