Hip COPY Flashcards
FAI: CAM
Morphological abnormality of superior-anterior aspect of the femoral head neck
FAI: Pincer
Excessive bone growth of the superior anterior aspect of the acetabulum
FAI: Demographics
- 20-40 years old
- male
- groin pain w/ hip rotation, in sitting position or after sports
FAI: Clinical Exam
- loss of hip IR
- limited flexion
- grinding/popping w/ hip ER
Labral tear:
- most common MOI?
- most common location?
- MOI: rotation in weightbearing
- location: anterior
4 types of labral tears:
- radial flap
- longitudinal peripheral
- radial fibrillated
- abnormally mobile
What is the most valid test for dx of a stress fracture?
- fulcrum test
Snapping Hip Syndrome:
- AKA:
- Sx:
- External vs Internal:
AKA: Coxa Saltans
- Sx:
- snapping sensation in and around hip when it is in motion
- External vs Internal:
- external (most common) IT band; snapping over the greater trochanter
- internal: iliopsas tendon snapping over the bony prominence of the pelvis (Femoral triangle, lesser trochanter)
Most common injury to the lateral knee?
IT band syndrome
- inserts on gerdy’s tubercle & proximal aspect of the fibular head
Sports hernia:
AKA:
Treatment:
AKA: Athletic Pubalgia
Chronic, conservative management doesn’t work
Define femoral anteversion
- Test?
Anything greater than 15 degrees
Craigs Test: measures femoral antversion and retroversion
What are possible compensations of femoral anteversion?
- external tibial rotation
- lateral rotation at the knee
- lumbar rotation to the same side
What is an indicator that a hamstring injury will take longer to rehabilitate?
Injury to the proximal free tendon
- ie. Semimembranous during kicking or dancing
What is an indicator that a hamstring injury will take LESS time to rehabilitate?
Injury to intramuscular tendon or aponeurosis
- ie. Biceps femoris during high speed running
What are the borders of the femoral triangle?
Superiorly: inguinal ligament
Medially: medial border of adductor longus
Laterally: medial border of sartorius
Floor: Adductor longus, Pectinus, and iliopsas
What is a precipitating factor in adductor strains?
Adductor strength
When do you initiate eccentric hamstring activation in hamstring strain rehab?
Phase II
What is the normal angle of inclination?
125-130 degrees
What does the center edge angle measure?
Normal seating of the femoral head (normal = 20-25 deg)
Less than 20 deg = acetabular dysplasia
Pincer FAI on XRay: what sign would you see?
Cross over sign
CAM FAI on XRay: what would you see?
pistol grip deformity on femoral neck
Frontal plane pelvo-femoral stability is mediated by what muscle groups?
Gluteus medius
tensor fascia latae
adductor complex
quadratus lumborum
What is the most significant risk factor for SCFE?
Obesity
What mechanical version will you see in a patient w/ SCFE?
Femoral or acetabular retroversion
How should a SCFE be managed? Stable or Unstable
ORIF
