Coccydynia is a rare but painful disorder characterized by axial coccygeal pain which is typically exacerbated by pressure. Management includes physical therapy/rectal manipulation, use of anti-inflammatory medications, modality use, coccygectomy, and fluoroscopically guided steroid injections. There are no studies documenting the efficacy of fluoroscopically guided coccygeal steroid injections in patients with coccydynia. ⋯ Patients with acute pain (less then 6 months) are more likely to respond to fluoroscopically guided coccygeal steroid injections.

Neuropathy of the median nerve within the carpal tunnel (carpal tunnel syndrome) has an age adjusted incidence of 105 cases per 100,000 person years. Treatment of carpal tunnel syndrome ranges from conservative management with medication and exercise to surgical release of the median nerve. Conservative treatment accounts for a significant portion of resources utilized and includes splinting, nerve gliding, ultrasound, and carpal bone mobilization. ⋯ After a successful diagnostic median nerve block at the cubital fossa, pulsed radiofrequency of the median nerve was performed on the left side at the cubital fossa, under ultrasound guidance. Radiofrequency probe adjustment around the nerve was conducted under live ultrasound guidance and multiple pulsed treatments were applied at anatomically distinct sites over the nerve. A 70% reduction in pain was reported over the follow up period of 12 weeks.

Stellate ganglion block is utilized in the diagnosis and management of various vascular disorders and sympathetically mediated pain in the upper extremity, head and neck. The cervical sympathetic chain is composed of superior, middle, intermediate, and inferior cervical ganglia. However, in approximately 80% of the population, the inferior cervical ganglion is fused with the first thoracic ganglion, forming the stellate ganglion also known as cervicothoracic ganglion. ⋯ Real-time ultrasound imaging prevented inadvertent injury to the esophagus as well as the thyroid gland and vessels. Ultrasound-guided block may improve patient safety by avoiding the soft tissue structures in the needle path that can't be readily seen by fluoroscopy. This may be particularly useful in the patient with asymptomatic pharyngoesophageal diverticulum (Zenker diverticulum).
