Q

Name the 3 Gluteus muscles with actions and innervations

A

Gluteus Maximus - Extensor of thigh - Inferior Gluteal Nerve
Gluteus Minimus - Abducts and medially rotates - Superior Gluteal Nerve
Gluteus Medius - Abducts and medially rotates, secures pelvis during gait (trendelenburg sign if not functioning) - Superior Gluteal Nerve

2
Q

Name gluteal region muscles (tip - there are 9) and innervations

A

Tensor Fascia Lata - superior gluteal nerve
Gluteus Medius - Superior gluteal nerve
Gluteus Minimus - Superior gluteal nerve
Gluteus Maximus - inferior gluteal nerve
Piriformis - Nerve to piriformis
Gemeli Superior - Nerve to obturator internus
Obturator internus - Nerve to obturator internus
Gemeli inferior - nerve to Quadratus femoris
Quadratus femoris - nerve to Quadratus femoris
Obturator externus (anterior thigh) found below quadratus femoris
NB - piriformis To quadratus femoris is in the order above (inferior to superior)

Remember by: The 3 Queer Gladiators Performed Generally Okay.
For order: P - Go Go - Q

Q

What laterally rotates within the gluteal region?

A

Piriformis (also abducts)
Obturator internus (also abducts)
Gemeli Superior and inferior (also abducts)
Quadratus femoris
Gluteus Maximus (also abducts and extends)

4
Q

What nerve exits the gluteal region posteriorly and what is its route?

A

Sciatic nerve - inferior to the piriformis. It then passes down the back of the leg splitting into the tibial and common fibular (peroneal) Nerve.

5
Q

What are the 3 bones of the hip and what to they form?

A

Pubis, Ischium and ilium

Form the acetabulum

6
Q

What creates the fibrocartilagnious collar of the hip joint?

A

Acetabular labrum

7
Q

What is the common dislocation of the hip and what are the clinical features?

A

Posterior Dislocation - femoral head forced posteriorly where the joint capsule is weakest
Leg will be shortened and medially rotated - can have sciatic nerve injury

8
Q

What is the common movement of muscles of the gluteal region?

A

Abduction of the leg
