Ultrasound-Guided Needle Release Combined with Corticosteroid Injection for the Treatment of Supinator Syndrome
May 26th, 2023
The deep branch of the radial nerve can easily be compressed at the arcade of Frohse due to its anatomical features. Ultrasound-guided needle release combined with corticosteroid injection is an effective and safe treatment for deep branch radial nerve adhesion.
Our research direction is musculoskeletal ultrasound. The protocol showed our process of an ultrasound-guided needle release combined with a corticosteroid injection to treat supinator syndrome. With the help of real-time ultrasound guidance, we can observe the nerve and its surrounding tissues and the safety compared with the convention and the safety compared with the convention the entire treatment is compensated with the syndrome.
The deep branch of the radial nerve can easily be compressed at the arcade of Frohse due to its anatomical features. Ultrasound-guided needle release combined with corticosteroid injection is an effective and safe treatment for deep branch radial nerve adhesion. Ultrasound-guided needle release plus corticosteroid injection for treating the supinator syndrome provides smaller incision, less cost, less treatment time, and faster recovery than open surgery.
Ultrasound-guided needle release plus corticosteroid injection is better for clinical application. In the future, we will use ultrasound-guided needle release post-corticosteroid injection and treat more peripheral nerve entrapments. Begin the ultrasound instrument setup by entering the patient ID number and the patient's name to save the images.
Sanitize the ultrasound probe using equipment disinfectant wipes. Perform all the procedures with the probe covered with surgical gloves. To set the image of the DBRN in the middle of the screen, perform cross-sectional scanning along the patient's supinator muscle to find the DBRN.
Then rotate the probe at 90 degrees to obtain a long axis section. Under continuous ultrasound guidance, separate the adhesion between the surrounding tissue of the posterior spin muscles and the DBRN. Ask the patient to sit and place the patient's arm in a flexed 20 degrees position on the examination bed.
Perform ultrasound to check for DBRN adhesion to the surrounding tissue. To begin the ultrasound examination, disinfect the patient's skin three times using complex iodine. Then place a sterile surgical towel on the patient's arm.
After providing the local anesthesia, identify the radial nerve by transversely using the probe at the level of the lateral epicondyle of the humerus. The radial nerve is located between the humerus muscle and the brachial radial muscle. Then move the probe distally to find the deep branch of the radial nerve between the deep and superficial layers of the supinator.
Use a 5 mL syringe to separate the adhesion between the surrounding tissue of the posterior spin muscles and the DBRN under continuous ultrasound guidance. Perform needle release from the DBRN distal area to the proximal area. Prick the adhesion tissue back and forth with the tip.
Control the probe and the needle accurately and ensure the tip is visible during the entire operation. Stop if there is resistance between the syringe and the tissues around the DBRN to avoid damaging the DBRN. After the procedure, inject a mixture of 1 mL of corticosteroid betamethasone and 2 mL of 2%lidocaine into the superficial area of the DBRN.
One month after the treatment, the finger joints were fully straightened. Upon fully straightening the fingers, the dorsal extension of the ring and little fingers was significantly improved by 15 degrees and 25 degrees respectively. Three months after the treatment, the range of DBRN adhesions was significantly reduced compared to DBRN adhesions before the treatment.
The dorsal extension of the ring and little fingers was also improved by 10 degrees and 15 degrees respectively. After one month, when the same treatment was performed for the second time, the joints of the fingers were fully straightened with the ring finger and little finger at zero degrees, indicating the dorsal extensions of the ring and the little fingers were normal.
