Crochet the Pain Away: A Case Study of Osteopathic Manipulation for Cervical Rib Induced Thoracic Outlet Syndrome

Abstract

\n \n \n Many people experience symptoms of thoracic outlet syndrome each year; one cause of these symptoms is the presence of cervical ribs. Cervical ribs have an estimated prevalence of 2% in the general population and 8.3% of those with thoracic outlet syndrome symptoms.1 Current treatment for thoracic outlet syndrome includes physical therapy and surgical resection. Techniques have been described for the treatment of thoracic outlet syndrome with osteopathic manipulation, but no specific treatment for cervical ribs was noted on a literature review.\n \n \n \n 25-year-old healthy female presents with intermittent hand numbness and tingling along the C8 distribution that worsened with crocheting. She had also noted for many years the presence of a hard-supraclavicular mass on her left side. Palpation of this mass showed a bony protrusion that stopped 2 cm posterior to the clavicle on the left, but no mass noted on the right. Records review revealed an x-ray confirming cervical rib on the left.\n \n \n \n After the treatment of surrounding dysfunctions without improvement in symptoms, the cervical rib was identified, manually isolated, and treated with direct myofascial release with respiratory assistance. This treatment provided immediate resolution of her symptoms. She remained asymptomatic for 10 days after treatment. A repeat treatment at two weeks resulted in resolution of her symptoms as far out as three months.\n \n \n \n Cervical ribs are common in patients with thoracic outlet syndrome, and treatment for these patients typically includes physical therapy followed by surgical intervention for non-responders. We propose that OMT, with a focus on direct myofascial release, may be effective in alleviating symptoms for patients with cervical ribs. A limitation of this study is that it is a case report of one young active female. A larger study that includes various ages, activity levels, and both sexes would be more generalizable.\n \n \n \n Direct myofascial release is an effective technique for treatment of cervical rib induced thoracic outlet syndrome when myofascial restrictions are present.\n
