Up to 20% of all patients with pectoral symptoms have an underlying orthopedic problem. The most common orthopedic conditions that may mimic chest pain radiating into the left arm include slipped disc, cervicothoracic tension syndrome, blockage of intervertebral or rib joints, and intercostal neuralgia. Less common causes of such pain are arthrosis of the shoulder, spondylocystitis, osteoporotic fractures or tumors of the bone. Management is oriented to the underlying cause, and treatment extends from physiotherapeutic measures (rest, heat treatment) via medication (non-steroidal anti-inflammatory drugs, myotonolytic agents) to operative interventions.
