Utilizing an ultrasound guided 5-in-1 trigger point and hydrodissection technique for interscapular mid-thoracic myofascial pain: A retrospective review

Abstract

Poor posture can lead to excessive strain of the neck and upper back musculature, leading to irritation of the dorsal scapular nerve (DSN) and spinal accessory nerve (SAN). A 5-in-1 trigger point technique has been described that specifically target trapezius, rhomboids, levator scapulae, SAN and DSN in a single percutaneous injection. We modified the technique to include hydrodissecting the DSN and SAN to provide further pain relief from possible nerve entrapments. Our retrospective review revealed that the modified 5-in-1 technique is a safe and effective way to address medial periscapular pain, often seen with anterior head carriage and upper crossed syndrome. Patients who received the modified 5-in-1 technique had statistically significant pain relief, allowing them to participate in rehabilitation programs.
