- Trendelenburg Sign
Trendelenburg’s Test also known as Trendelenburgs sign is found in people with weak or paralyzed abductor muscles of the hip, particularly gluteus medius and minimus, usually due to an underling condition such as Osteoarthritis of the hip or hip fracture/dislocation.
- Patient stands, examiner instructs patient to stand on one leg & observes the iliac crests bilaterally.
- Normally when one leg is lifted the iliac crests should stay level.
- Test is repeated on other leg.
About 10% of patients with hip pain will demonstrate a false positive on Trendelenburg test (muscle weakness due to pain)
