Front 1

The anterior portal for hip arthroscopy lies at the intersection of what two landmarks?

Back 1

Vertical line from ASIS
Horizontal line from the greater trochanter

Front 2

What two structures are at risk with the anterior portals?

Back 2

Lateral femoral cutaneous nerve
Femoral vessels

Front 3

What other two portals are commonly used and where do they lie?

Back 3

Anterolateral portal
Posterolateral portal
On either side of greater trochanter

Front 4

What two structures are at risk with the anterolateral portal?

Back 4

Superior gluteal nerve
Lateral femoral cutaneous nerve

Front 5

What two structures are at risk with the posterolateral portal?

Back 5

Sciatic nerve

Front 6

What patients are at highest risk for developing labral tears?

Back 6

Those with acetabular dyplasia

Front 7

What is the fundamental problem? How does this relate to acetabular version?

Back 7

Anterior over-coverage
Excess acetabular retroversion

Front 8
