Calcific tendinitis is a common source of musculoskeletal pain in adults; however, it is rarely encountered in children. Calcific tendinitis is the most commonly encountered manifestation of hydroxyapatite deposition disease, in which calcium hydroxyapatite crystal deposition occurs in tendons. It may cause acute or chronic pain, or may be entirely asymptomatic. We describe a case of acute calcific tendinitis of the flexor pollicis longus tendon in an 8-year-old boy, who initially presented to our department for workup of a mass felt along the volar aspect of the right wrist.

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.

To evaluate technical success, complications, and effective dose in patients undergoing CT fluoroscopy-guided iliosacral screw placement for the fixation of unstable posterior pelvic ring injuries. ⋯ CT fluoroscopy-guided screw placement for the treatment of posterior pelvic ring instabilities can be performed with high technical success and a low complication rate. This method provides excellent intrainterventional visualization of iliac and sacral bones, as well as the sacral neuroforamina for precise screw placement by applying an acceptable effective patient dose.
