Q

Open packed position of the hip

A

FABER
One of the only joints where openpacked position is optimal articular contact, not the closed packed position.
Flexion and external rotation tend to uncoil the ligaments and make them slack

Q

How do you distinguish Synovitis from septic arthritis

A

Septic arthritis:
Will present with fever, malaise and decreased appetite. Young: two years old, Hip held an open pack position to due to pain
Tx: Aspiration, IV and antibiotics.

Synovitis
inflammation of synovial lining
Not medical emergency like septic arthritis. Usually has upper respiratory infection. Can lead to AVN. Decreased hip IR due to pain, fever LESS than 101
Tx: managed with partial weight-bearing now and imaging needed due to soft tissue origin

Q

Diagnosis of Labral tear anterior vs posterior. Which is more common?

A

Rule out labral tears using FABER, if (-) than tear isnt there. FABER is a intra-articular sign. Clicking is a good way to rule in, moderate association

Resisted SLR tests the posterior labrum. Test position is in ER and ABD

Femoral impingement test: will test the anterior and superior labrum, position of IR and ADD for test.

25
What does the sciatic nerve branch into
L4-S3 Branches off to the tibial nerve and common peroneal nerve. -Common peroneal nerve goes to short head biceps and and splits into the superficial (innervates lateral leg muscles) and deep peroneal nerve to innervate anterior leg muscles
26
what is the sciatic nerve innervation and what the relationship to the pirifomris
L4-S3, Sciaitc N runs through the piriformis and superior gluteal nerve innervates the piriformis
27

Must rule out lower back pain Relief with sitting may occur due to decreased pressure on inguinal nerve Tests: Pelvic compression test to decrease pain, Femoral N neuro dynamic testing
29
How can you distinguish: Bursitis, Glutemedius and minimus tendinopathy, tendon tear, and IT band, snapping hip syndrome
-Bursitis will feel boggy to palpation - Tendinopathy will react to activity and will have muscle based signs such as weakness, trendelenburg and + ER derotation test -Tear will have a related MOI and *dramatic weakness* - IT band syndrome/ snapping hip will have + Obers test, TFL hypertrophy, snapping will distinguish it from IT band pathology -Internal snapping hip is also known as coxa sultans and affects the femoral head and the illiofemoral ligament
30
What is Coxa Sultans
- Internal snapping hip is a syndrome - Caused by the snapping of the iliopsoas tendon over the underlying hip capsule and femoral head. - Popping with repetitive active hip flexion and extension - doen't have to snap to make the diagnosis
31
What is elys test
Patient lays prone and you flex one knee. Also called Thomas test. Positive for rectus femoris tightness if the hip of the leg that is flexed pops up off the table
32
What is the FAI progression
FAI can be associated with labral tears. Impingement and related tears can lead to joint arthritis Labral tears are due to bony issue or abnormality and can lead to FAI or developmental dysplasia
32
What are types of hip impingement
CAM - "Fat neck" aspherical femoral head with bony prominence at antero-lateral head and neck junction impinges on rim. Lleads to superior OA. Seen in young athletic males FADIR causes pain and is better test than FABER. PINCER- over coverage of head by acetabulum, which pinches neck. Can lead to posterior-inferior or central OA. Middle aged females Ext and ER cause pain
33
What is the imaging gold standard for FAI

Hip weakness, anterior pelvic tilt, shortened hip flexors, weak core
48
What would you expect to find in a patient with hip microinstability
Hyper-mobility controbutign the micro instability, pain, apprehension, possible connective tissue disorder with at least four out of five score on Bighton score for mobility
49
A patient with underlying hip micro instability would have familiar symptoms with which motions?
External rotation + extension is a feeling of apprehension. Will present with ER and shortened hip flexors Cluster: or Abduction Hyperextension External Rotation Test (AB-HEER performed in SL), prone instability, HEER tests (pretty much the thomas test)
50

Nordic hamstring exercise in superior exercise warm-up, strengthening, RTS movement
60
How to distinguish ishiofemoral impingement from hamstring injury
distinguish impingement from hamstring using active and passive range of motion of knee flexed and extended. Hamstring MMT shouldn't recreate symptoms in impingement.
61
What are differential diagnosis for greater trochanteric pain syndrome and how to distinguish
Bursitis, external snapping hip, Glute minimus/medius tendon apathy or can be distinguished from one another with palpation. GTPS will have aggravating factors of pain with active adduction, hip weakness, pain with direct pressure such as laying on the side prolonged activities of walking
62
What is the underlying cause of GTPS
Tissue compression over GT due to overuse, leads that TFL hypertrophy and/or weak ABductors ,tissue compression and poor frontal plane control (Trendelenburg). This leads to impairments such as TFL hypertrophy and pain cycle.
63
Patient profile GTPS and differential diagnosis
Females in 40s to 50s and athletes. Rule out hip OA. Related to muscular impairments excess IR and ADD may cause TFL adn IT issues aggravation with laying on side and prolonged activities

Gluteal tendinopathy will present in middle/older woman with weak abductors and external rotators. Trendelenberg sign will be present pain, single leg stance with less than 30 seconds positive the rotation test Glute tear: Will present with more severe weakness with the potential for severe pain and Echymosis if a cute. To be treated with irritability level based interventions
65
What is return to sport criteria for hip flexion and abduction injuries
Adductots strength greater than 80% of hip abductors
66
What are the short term, intermediate and long-term goals for hip hamstring injury rehab progressions
Acute: symmetrical ROM, normalized gait, no pain with submaximal isometrics Subacute: symmetrical hamstring strength, adequate control, eccentric exercises OK, symptom free jogging Late RTS goals: strong and pain-free all ROM, no apprehension with H - test, plyos high velocity and perturbation training
67
What is the pain monitoring model for hamstring injury rehab progressions
<4/10 pain during tx for optimal strength gains
68
Characteristics of femoral nerve neuropathy versus saphrenous nerve neuropathy
Femoral nerve neuropathy: quad weakness, entrapment is at the hip flexor if hip flexor weakness is present. hip flexion is spared if the entrapment is under the inguinal ligament. Decreases patella DTR and sensation in thigh and saphrenous pattern (medial knee, lower leg, medial foot, first MTP) Saphenous nerve neuropathy sensation only in saphenous nerve pattern
69
Distinguish obturator nerve neuropathy from lateral femoral cutaneus nerve neuropathy
Obturator nerve neuropathy will affect adductors and sensation at the medial thigh. Entrapment at adductors. Expect aggravation with hip extension and adductor stretch LFCN No weakness sensation loss ONLY over lateral thigh Aggravated with tight belts/clothing. + tinel test at ASIS or just medial to it. Also known as meralgia persthetica
