What is the prevalence of Thoracic Outlet Syndrome?
How many people does Thoracic Outlet Syndrome affect? Does it have the same prevalence in men and women? And in the different countries?
Thoracic Outlet Syndrome (TOS) is a relatively rare condition affecting the upper body. While exact prevalence rates are challenging to determine due to underdiagnosis and varying definitions, it is estimated that TOS affects approximately 0.3% to 8% of the population. The condition is more commonly observed in women and individuals involved in repetitive arm movements or occupations requiring prolonged overhead activities. TOS can cause symptoms such as pain, numbness, and weakness in the neck, shoulder, and arm. Early diagnosis and appropriate treatment are crucial for managing this condition effectively.
Thoracic Outlet Syndrome (TOS) is a condition characterized by compression of the nerves and blood vessels in the thoracic outlet, which is the space between the collarbone and the first rib. It can cause pain, numbness, and weakness in the upper extremities.
The prevalence of TOS varies depending on the population studied and the diagnostic criteria used. However, it is estimated that TOS affects approximately 1 to 2% of the general population. It is more commonly seen in women than men, with a female-to-male ratio of about 3:1.
TOS can be classified into three main types: neurogenic, venous, and arterial. Neurogenic TOS is the most common form, accounting for about 95% of cases. Venous TOS is less common, comprising around 3-4% of cases, while arterial TOS is the rarest, making up less than 1% of cases.
Although TOS can occur at any age, it is most commonly diagnosed in individuals between the ages of 20 and 50. Certain risk factors, such as repetitive arm movements, poor posture, trauma, and anatomical variations, may increase the likelihood of developing TOS.
Early diagnosis and appropriate treatment are crucial for managing TOS and improving patient outcomes. If you suspect you may have TOS, it is important to consult with a healthcare professional for a proper evaluation and personalized treatment plan.
