Q

Describe innervation of the superficial muscle group of the gluteal region?

A 
Gluteus maximus is supplied by inferior gluteal nerve. 
All others (gluteus medius, gluteus minimus and tensor fascia latae) are supplied by the superior gluteal.

Q

What is Trendelenburg’s gait?

A

A clinical sign. When you lift a leg, the pelvis tilts and the muscles pull it back into alignment. In Trendelenburg’s gait, the superior gluteal nerve has been damaged, allowing the pelvis to tilt to the unsupported side. The contralateral side then drops. The limb is now too long. The patient leans to the opposite side to shorten the limb.
