Video 1: Ultrasound-Guided Caudal Epidural Injection
CAUDAL epidural anesthesia is the injection of medications into the epidural space via the sacral hiatus. It is useful when anesthesia of the lumbar and sacral dermatomes is needed. Successful caudal anesthesia relies on the proper placement of a needle in the epidural space. This technique is also useful in treating patients with low back pain. This video demonstrates how ultrasound-guided caudal epidural injection is performed.

Video 2: Ultrasound-Guided Piriformis Muscle Injection
Piriformis syndrome is considered by many clinicians as a condition in which the piriformis muscle physically irritates the sciatic nerve because of strain, overuse, or anatomic anomaly. Persons with this syndrome often present with ipsilateral numbness, tingling, and pain in the buttocks, thigh, and leg, resembling features of sciatica. Approximately 6 - 8% of low back pain can be attributed to the piriformis syndrome, which remains a diagnosis of exclusion, after other etiologies such as spinal nerve root compression have been ruled out. This video demonstrates how ultrasound-guided piriformismuscle injection is performed.

Video 3: Ultrasound-guided Injection Treatment of Retrocalcaneal Bursitis
Inflammation of the retrocalcaneal bursa can limit function and causes pain in the heel and ankle joint areas. Pain anterior to the Achilles tendon and superior to the calcaneus is the hallmark of retrocalcaneal bursitis. Retrocalcaneal bursitis is common in runners because repetitive ankle dorsiflexion augments stress on the bursa. Patients with hindfoot varus and rigid plantarflexed first ray are also susceptible to retrocalcaneal bursitis. When bilateral retrocalcaneal bursitis is present, the diagnosis of inflammatory arthritis is highly possible. Treatment options of retrocalcaneal bursitis includethe application of ice on the painful area, modifying one’s activities, taking nonsteroidal anti-inflammatory drugs, and wearing orthoses. This video demonstrates how ultrasound-guided injection treatment of retrocalcaneal bursitis is performed.

Video 4: Ultrasound-guided Sacroiliac Joint Injection Technique
Sacroiliitis is an inflammatory process frequently involving one or both sides of the sacroiliac (SI) joints. It is one of the major clinical features of spondyloarthropathies. Treatments for sacroiliitis include taking nonsteroidal anti-inflammatory drugs, and the application of physical modalities. However, in severe painful cases, local treatment of the SI joint through intra-articular corticosteroid injection can provide fast and considerable clinical improvements. This video demonstrates how ultrasound-guided sacroiliac joint injection technique is performed.
