Magnetic resonance imaging (MRI) is frequently used in the evaluation of degenerative conditions in the lumbar spine. The relative interrater and intrarater agreements of MRI findings across different pathologic conditions are underexplored, as most studies are focused on specific findings. ⋯ Even in a study using standardized evaluation criteria, there was significant variability in the interrater and intrarater agreements of MRI in assessing different degenerative conditions of the lumbar spine. Clinicians should be aware of the condition-specific diagnostic limitations of MRI interpretation.

Anterior cervical discectomy and fusion using cervical plates has been seen as effective at relieving cervical radiculopathy and myelopathy symptoms. Although it is commonly used, subsequent disc degeneration at levels adjacent to the fusion remains an important problem. However, data on the frequency, impact, and predisposing factors for this pathology are still rare. ⋯ We found that over the long term, at a minimum follow-up point of 10 years, a plate-to-disc distance of less than 5 mm, having spondylosis, and undergoing multilevel fusion were predisposing factors for the occurrence of clinical adjacent-segment pathology. Nevertheless, the incidence of clinical findings of adjacent-segment pathology was much lower than the incidence of radiographic findings. Also, the rate of follow-up surgery was low. Therefore, anterior cervical discectomy and fusion using cervical plates can be considered a safe and effective procedure.

The Internet is frequently used by patients to aid in medical decision making. Multiple studies display the Internet's ineffectiveness in presenting high-quality information regarding surgical procedures and devices. With recent reports of unacceptably high complication rates and poor outcomes with the X-Stop device, it is important that online information is comprehensive and accurate. This study is the first to examine Internet information on the controversial X-Stop. ⋯ Our study demonstrates the Internet's ineffectiveness in reporting quality information on the X-Stop. Information was often incomplete and potentially misleading. Significant controversy exists within primary literature regarding the safety and efficacy of the X-Stop. Yet, publicly available Internet information largely provided misinformation and did not reflect any such controversy. This raises the concern that such information lends itself more toward patient recruitment than patient education. Medical professionals need to know how this may affect their patients' decision making.
