Trendelenburg Test for Hip Stability The Trendelenburg test assesses for hip stability The examiner sits behind the patient and places thumbs in the posterior superior iliac spines and hands on the iliac crests to check for level height. The patient then stands on one leg with raised unsupported leg flexed at the knee and hip. In normal function, the unsupported pelvis elevates slightly, indicating the gluteus medius muscle appropriately abducts the supported hip. If the pelvis drops on the unsupported side or remains level, it's considered a positive Trendelenburg, indicating a weak gluteus or intra-articular pathology in the supported hip.
