What is the Trendelenburg test?

The

Trendelenburg test may actually refer to two different medical examinations: one is given to determine any uncompension of valve in varicose veins, while the other is given to patients to evaluate the procedure of hip joints. In this way, the test has different purposes for musculoskeletal and circulatory systems. In both cases, the Trendelenburg test can be performed independently or with other medical tests to assess the health of the patient or the procedure of the current disease. The name of the test was in honor of Friedrick Trendelenburg, a perfect German surgeon in the 19th century, which introduced many surgical techniques and mentor several surgeons. This is to empty the veins of blood that flows into it. The doctor or the examiner then places the turnstile, a tool that helps stop blood flow, around the upper thigh. Once the turnstile is in place, the patient is asked to get up and then the doctor will observe the blood replenishment in the veins.

for normalThe emptied veins will be filled with blood from bottom to top in about 30 seconds, because the turnstile only slows down the filling and does not block it. If the veins have not been filled before or after 30 seconds or if the veins are filled from above, some holes or valves of the veins may be incompetent. Fast and sudden blood flow to the veins after the turnstile is removed can also be diagnosed as the incompetence of the valve. The Trendelenburg test can be repeated in different areas until a blocked or twisted vein is determined.

If the Trendelenburg test is to explore the hips, the first step for the patient is to stand or to balance on one leg without a foot, while the examiner puts his fingers on the front superior of the iliakal spine located just above the buttocks. In some cases, the examiner observes only from behind and does not touch the patient. To raise one leg, the patient should bend his knee, so the weight is fully supported by the sides and not the upper thigh. The patient may be asked to hold the position for a period of time30 seconds, or lift one leg at different angles.

The patient may have some hip problems if they lean too much towards the leg on which it stands, or if the hip in which the leg is attached is lower than the other side. A similar diagnosis can also be made if the patient cannot maintain the position for 30 seconds. The diagnosis can range from skeletal equalization, muscle weakness in the hip or even from the type of neurological disorder that prohibits man to balance.
