Innervation: anterior rami of spinal nerves C4 to C6īlood supply: ascending cervical artery branch of the inferior thyroid artery.įunction: bilateral contraction- neck flexion unilateral contraction- neck lateral flexion (ipsilateral), neck rotation (contralateral), elevation of the first rib. Insertion: anterior scalene tubercle of the first rib, superior border of the first rib (anterior to subclavian groove) Origin: anterior tubercle of transverse processes of the vertebrae C3 to C6 The phrenic nerve crosses its anterior surface. It is also located between the subclavian vein and the subclavian artery. It is deeply located and lying behind the Sternocleidomastoid. This muscle is one of the lateral sides of the neck muscle, it belongs to the scalene group. Sometimes a fourth muscle, the scalenus minimus, is present behind the lower part of the scalenus anterior.

Trigger points radiate pain to the affected area when pressure is on sensitive points and sometimes spontaneously with no pressure, and sometimes in seemingly not related body parts. This pain is related to trigger points in muscles. Fascia is thin and white animal tissue wrapped around all the muscles. It’s a chronic pain condition that causes pain within the system. “Myo” means muscle and “fascial” means fascia. Moreover, clinical findings for this syndrome are “pathognomonic”. In scenarios, patients may commit to surgical intervention. It is often diagnosed as being another pain related to radiculopathies, like thoracic outlet syndrome, cervical spinal stenosis, and cervical disc herniation.īecause this syndrome causes cervical radiculopathy, this condition may additionally result in mismanagement which ends in pain and suffering. Despite this, scalene myofascial pain syndrome could be a well-known medical entity. Scalene myofascial pain syndrome may present as primary or secondary to essential cervical pathology. Scalene myofascial pain syndrome could be a regional pain syndrome wherein pain originates over the neck area and radiates down toward the arm. What Is Scalene Myofascial Pain Syndrome?
