Thoracic Outlet Syndrome Treatment in Brea
Thoracic outlet syndrome (TOS) is a condition that occurs when blood vessels or nerves in the space between your collarbone and first rib—known as the thoracic outlet—become compressed. This compression can lead to neck and shoulder pain, numbness or tingling in the fingers, and weakness in the arm. For some patients, the symptoms can interfere with daily activities and reduce overall quality of life.
There are several common causes of TOS. Physical trauma, such as a car accident, can create scar tissue or misalignment that compresses nerves or blood vessels. Repetitive strain from sports or work-related activities—especially overhead movements—can irritate or inflame the thoracic outlet region. Certain anatomical variations, like having an extra rib (cervical rib), can narrow the space and make compression more likely. Pregnancy can also temporarily alter posture and muscle tension, increasing the risk of TOS.
Thoracic outlet syndrome is generally categorized into three types:
Neurogenic TOS – The most common type, caused by compression of the brachial plexus, the network of nerves controlling the shoulder, arm, and hand. Symptoms include numbness, tingling, and weakness in the affected arm or hand.
Venous TOS – Occurs when one or more veins under the collarbone are compressed, which may result in blood clots and swelling in the arm.
Arterial TOS – The least common type, caused by compression of the arteries under the collarbone, sometimes leading to aneurysm formation and impaired blood flow.
Dr. Tenckhoff provides non-surgical care for TOS using Cox Technic Flexion Distraction and Decompression to reduce pressure on nerves and vessels, improve spinal alignment, and relieve pain. Patients are also guided in stretching, strengthening, and posture strategies to maintain thoracic outlet space and prevent recurrence, promoting long-term relief and improved arm and shoulder function.
