Trendelenburg sign
The Trendelenburg sign (after the surgeon Friedrich Trendelenburg ; English Trendelenburg's sign ) is the name given to the clinical picture of paralysis of the glutei medius and minimus muscles , which can be caused by damage to the superior gluteus nerve . A congenital dislocation of the hip joint as well as a coxa vara , hip joint arthrosis , Duchenne muscular dystrophy or Perthes disease can also be the cause of a positive Trendelenburg sign.
The Trendelenburg sign is considered positive as soon as the patient cannot keep his pelvis in balance while standing on one leg - whereby the muscles of the supporting leg are affected. When walking you can recognize the Trendelenburg sign by tilting the pelvis to the healthy side with simultaneous flexion of the free leg in the hip and knee. It creates the impression that the patient is "waddling".
Strengthening and coordination exercises as well as stretching the hip-stabilizing muscles (gluteal muscles and tensor fasciae latae muscles ) can counteract the Trendelenburg sign.
The Trendelenburg test , also developed by Friedrich Trendelenburg, on the other hand, is the name for a test in the field of phlebology and is used to detect valve insufficiency in the perforating and stem veins on the lower leg.
