Q

Describe the Trendelenburg/Hip Drop gait and the key anatomy behind it.

A

This abnormal gait arrises from weakness of the hip abductor muscles and is characterized by the opposite/contralateral hip dropping during ambulation.
Weakness of the hip abductors, primarily gluteus medius makes it unable for the pelvis to remain stable during movement.
