Trendelenburg gait is an abnormal gait resulting from a defective hip abductor mechanism. The primary musculature involved is the gluteal musculature, including the gluteus medius and gluteus minimus muscles. The weakness of these muscles causes drooping of the pelvis to the contralateral side while walking. The gait gets its name from a German surgeon, Friedrich Trendelenburg, who first reported the test related to this gait in 1895. The physical examination test described by him is useful to uncover hip abductor weakness in a patient with developmental dysplasia of the hip.[1]
