Delayed Bone Infarct in the Ilium Following a Pelvic Crush Injury and Embolization: A Case Report.

Case: We present a case of delayed osteonecrosis of the ilium. After receiving embolization and multiple orthopaedic procedures following a complex pelvic crush injury, the patient subsequently developed posterior pelvic pain and tenderness over the posterior superior iliac spine, along with pain on sacroiliac joint compression. Magnetic resonance imaging of the pelvis demonstrated a bone infarction in the left ilium adjacent to the sacroiliac joint.

Herpes zoster radiculopathy treated with fluoroscopically-guided selective nerve root injection.

Background: Varicella-zoster virus, a member of the herpes virus family, is a neurotrophic virus that primarily affects afferent sensory neurons. Reactivation of latent virus within the dorsal root ganglion and axoplasmic transport to epithelial nerve terminals causes the segmental cutaneous rash and neuralgic pain characteristic of herpes zoster.

Setting: Outpatient orthopedic practice.
