30
Pathomechanically, is there more force on the hip joint with a larger degree of anteversion or retroversion?
Anteversion - femoral surface experiences majority of pressure on superolateral surface
31
What direction does the force on the acetabulum shift from and then to with gait?
IC/landing is posterolateral surface to propulsion on the anterolateral surface
32
What are three pathological indicators for labral tears and/or loose bodies?
1) sharp pain 2) giving way 3) catching/clicking 4) locking
33
What are differential diagnoses for groin pain with 1) coughing 2) sneezing 3) straining?
Hernia, pubic symphyseal afflication, tendinopathy of adductor magnus/rectus abdominis
34
How many provocation tests need to be positive to include SIJ as potential diagnosis?
3
35
Name the SIJ provocation tests - which is most sensitive, which is most specific?
1) SIJ distraction **most specific 2) SIJ compression 3) Thigh thrust ** most sensitive 4) Gaenslens 5) FABER 6) sacral thrust 7) ASLR
36
When is the ASLR considered positive?
When patient feels weakness and/or pain that limits ability to adequately complete maneuver (lift at least 8 inches/20 cm) -> clinician applies compression to innominates and will result improved ability and less pain
37
What isometric force should be applied to identify adductor longus and/or gracilis tendinopathy?
Hip in 0 deg flexion with adduction
38
What isometric force should be applied to identify tendinopathy of the symphysis pubis?
Hip in 45 deg of flexion with adduction
39
What isometric force should be applied to to identify tendinopathy of the pectineus muscle?
Hip in 90 deg flexion with adduction
40
What is the capsular pattern for the hip OA?
IR > flexion > extension > abduction (variability with flex, exten, abd)
41
What are the 5 predictor variables for OA for the hip?
1) self-reported pain with squatting 2) active hip flexion causes lateral hip pain 3) scour test with adduction causes lateral hip/groin pain 4) active hip extension causes pain 5) passive IR = 25 deg **biggest predictor 3 of 5 variables necessary
42
Which gender has more severe cases of hip OA?
Women > men
43
What two factors are predictors of good ambulation after THA?
Preoperative hip abduction and knee extension strength
44
What is the Drehmann sign?
Obligatory abduction and ER with passive hip flexion

Calcific tendonitis of glute med
57
What position is the hip put in for the Hip Lag Sign to be positive?
Sidelying; affected hip on top - 10 deg extension, 20 deg abduction, maximal IR with 45 deg of knee flexion - drops greater than 10 cm = positive
58
What diagnosis is consistent with pain or burning in the perineal area that worsens with sitting, improves with standing?
Pudendal nerve entrapment
59
What are three contributing factors for pudendal nerve entrapment?
Childbirth Pelvic surgery Bicycling (narrow saddle pressure)

How does one rule in/out a rectus abdominis strain with pain in groin region?
Perform resisted trunk flexion in supine
62
In cases of symphyseal separation, how can one MMT to aid with ruling in this diagnosis?
Resisted hip adduction with hip in 45 deg of flexion
63

Where do most labral lesions occur due to compromised mechanical properties?
Anterior superior - posterior superior | Superior region
66
Which form of FAI is due to a nonspherical femoral head/neck relationship?

Pincer
68
What form of FAI is typically associated with retroversion / profunda or protrusion?
Pincer
69
Stress fractures are clinically diagnosed with three tests:
1) WB pain and NWB pain relief 2) One legged hop test 3) Fulcrum test: clinician exerts progressive downward force to distal thigh with forearm under proximal thigh - reproduce sxs
70
