Randomized Controlled Trial Multicenter Study
The association between Modic changes and pain during 1-year follow-up in patients with lumbar radicular pain.
To examine whether Modic changes influence pain during a 1-year follow-up in patients with lumbar radicular pain. ⋯ Patients with lumbar radicular pain have a substantial pain reduction during 1-year follow-up, but Modic type I changes may imply a slower initial decrease in sensory pain.

The influenza vaccine is increasingly available to the general public and mandated by many employers in the United States. The prevalence of post-vaccination complications is likely on the rise. Complications are well known to general clinicians, but are under-reported in the imaging literature. ⋯ The most likely reason for a humeral intraosseous edema-like signal was presumed injection of vaccine substance directly into osseous structures that might lead to focal osteitis. In the published literature, there is little emphasis on the imaging of local injection site complications accompanying influenza vaccination. We intended to increase familiarity of MRI findings in the setting of prolonged or severe clinical symptoms following influenza vaccination through the imaging findings of these four cases.
