Ultrasonographic Imaging of Entrapment of the Palmar Cutaneous Branch of the Ulnar Nerve due to Accessory Abductor Digiti Minimi Muscle – Video 1

Video Author: Ke-Vin Chang
Published on: 04.22.2020

On the painful side, the accessory abductor digiti minimi muscle was observed. The muscle traveled through the Guyon’s canal and approximated distally to the abductor digiti minimi muscle. The palmar cutaneous branch of the ulnar nerve was seen arising from the radial side of its main trunk and radial to the ulnar artery and veins. The nerve was squeezed inside the Guyon’s canal by the accessory abductor digiti minimi muscle, rendering the nerve fascicle more flattened than that of the contralateral side.

Video#1- Detatchment of Posterosuperior Labrum in Dynamic US during abduction and external rotation in patients with posterosuperior labral tear.

Creator: Byung Joo Lee & Donghwi Park

Duration: 0:44

Video 1: This video shows dynamic ultrasound of a 60-year-old man with posterosuperior labral tear. Although there is not definite a posterosuperior labral tear in neutral posture, a detachment of posterosuperior labral tear were seen in dynamic ultrasound during abduction and external rotation posture. The abduction and external rotation motion of the glenohumeral joint usually induces the humeral head to rotate externally, which gives stress to the posterosuperior labrum. In a normal posterosuperior labrum, only a slightly blunted posterosuperior labrum without any detachment is detected during abduction and external rotation motion. However, this motion can induce posterior and medial detachment of the labrum in patients with damaged PS labrum.

Video 1: This is a dynamic ultrasonography of normal individual. Posterosuperior labrum appears as a fibrillary hyperechoic triangle, coursing around the shoulder joint capsule. During the ABER maneuver, there was no detachment of labrum or joint fluid leakage, although the PS labrum was pressed slightly by the pressure from ABER posture.

Video 2: This is a dynamic ultrasonography of a 36-year-old man with posterosuperior labral tear. Although the PS labrum appears as a fibrillary hyperechoic triangle in neutral position, hypoechoic lesion is distinct in PS labrum. During the ABER maneuver, leakage of the joint fluid through torn PS labrum can be seen. In this case the fluid flow through the tear is admittedly a subtle finding and the presence of a GHJ effusion (not seen in this case) may make this examination more difficult.

Adding a Transverse Scan in the Ultrasound Diagnosis of Extensor Tendinopathy

Creator: Yi-Chian Wang, Rachel J. Lew, Chia-Wei Lee, Yi-Pin Chiang

Duration: 3:37

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.

Creator: Carl PC CHEN

Duration: 2:14

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.

Ulnar nerve compression commonly occurs during elbow flexion due to its location in the aponeurotic arch of the flexor carpi ulnaris muscle, also referred to as the humeroulnar arcade. Ultrasonography is an easily accessible tool for dynamic examination of the ulnar nerve in different elbow positions. This video gallery presents a rare case of ulnar nerve compression during elbow extension revealed in dynamic ultrasonography.
