This video shows how ultrasound-guided cervical nerve root block (US-CRB) is done to the 5th nerve root level. The objective of CRB is to place the needle in the intertubercular groove situated between the nerve root and the posterior tubercle.

Extensor Tendinopathy (Tennis Elbow) is a common term used to describe pathology of the forearm extensor tendons that converge to anchor the muscles to the lateral elbow. During traditional ultrasonography using the longitudinal scanning method, it is difficult to determine which component of the common extensor tendon (CET) is affected. This video presents the addition of a transverse scan to better visualize the tendons that join and form the CET. Two cases seen in our ultrasound clinic were demonstrated. The findings from the transverse scan helped to provide modifications of specific wrist and hand activities to facilitate recovery.

AN ULTRASOUND VIDEO DEMONSTRATION FOR LUMBAR FACET JOINT INJECTION

The image revealed a flattened compressible mass superficial to the flexor tendon on the 3rd metatarsophalangeal joint. Slightly relocating the transducer toward the heel, we found another mass emerging from the 3rd intermetatarsal space, a common region for Morton’s neuroma. Under dynamic tracking, the connecting stalk between the intermetatarsal mass and the lesion overlying the 3rd toe flexor tendon might be considered as another hint for tendon-sheath related pathology. Its heteroechoic appearance and hypervasculairty were compatible with submetatarsal bursitis.

Needle electromyography in low cervical paraspinal muscles of a patient with EMG disease demonstrate increased insertional activity and myotonic discharges at 2 different sweep speeds; 20ms (video 1) and 500ms (video 2). Video 1: 20ms sweep displays a myotonic discharge that can appear as fibrillations and positive sharp waves or complex repetitive discharges. Video 2: 500ms sweep reveals the “wax and wane” characteristic specific to myotonic discharges. Myotonic discharges can have variable appearance and sound depending on sweep speed. By definition discharges need to last over 500ms and in 3 or more areas outside of an endplate.

Ulnar nerve subluxation or snapping triceps syndrome is the condition of anterior sliding of the ulnar nerve or part of the triceps muscle over the medial epicondyle during elbow flexion. This video presents the real-time dynamic visualization of the entire process of ulnar nerve subluxation and snapping triceps during joint movement of the elbow using ultrasonography.

This video showed dynamic scanning (transverse view) of two painful neuromas at the level of stump tip of a below-elbow amputee. After ultrasound-guided perineural steroid injections, the sizes of both neuromas decreased during follow up one month later. The patient also reported a marked reduction in pain and numbness of the stump tip and well tolerated an electronic arm prosthesis.

The authors demonstrated ultrasound-guided technique in treating carpal tunnel syndrome to avoid damaging the median nerve and adjacent soft tissue. Since the median nerve goes deeper at distal hamate level, distal approach may provide larger space for initial needle insertion. Under long-axial view, the whole stretch of median nerve could be visualized when the needle progressed proximally in the access of in-plane.

Injection treatment to the glenohumeral joint is often needed to treat shoulder problems such as adhesive capsulitis. This can be done through blind palpation technique, fluoroscopic or musculoskeletal ultrasound guidance. In recent years, ultrasound has been proven to increase the accuracy of needle placement into the glenohumeral joint.
Glenohumeral joint injection can be done through the anterior rotator interval approach or the posterior approach techniques. The posterior injection technique offers an easier and a more effective approach to the glenohumeral joint with less extravasation rate as compared with the anterior approach. The video demonstrates how the posterior injection approach is done through ultrasound guidance.
