This document discusses cervical rib, including its structure, symptoms, diagnosis, treatment options, and physiotherapy management. Cervical rib is an extra rib that grows from the base of the neck above the collarbone. It can compress nearby blood vessels and nerves, causing pain, numbness, and reduced circulation in the arm. Diagnosis involves imaging tests and physical exams like Adson's test. Treatment may include anti-inflammatory drugs, surgery to remove the rib, or physiotherapy focused on exercises to improve strength and mobility.
