IPPA MST 2 Flashcards
Describe Non-weight bearing activity of the hip
Open chain
Head of femur moves on acetabulum
Convex on concave
Roll and glide in opposite direction
Describe weight bearing activity of the hip
Closed chain
Acetabulum moves on head of femur
Concave on convex
Roll and glide in same direction
What is medial collapse pattern caused by weak abductors?
Contralateral pelvic drop

What is the difference between compensated and uncompensated trendelenberg?
Uncompensated- pelvic drop
Compensated- trunk to ipsilateral side to compensate for contralteral pelvic drop
What are the big signs in differentiating inter articular hip pain and lumbar structure?
HOPC- Valgus, internal rotation, young person sporting vs heavy lifting/sedentary
Aggs- kicking/cycling compared to bending over/walking
Special Q’s- clicking vs pain in cough and sneeze

What is the difference between alta and baja?
Alta is superior displacement of the patella
Baja is inferior displacement
What is varus and valgus?
Valgus knock kneed
Varus opposite
What degree of flexion/extension is the ACL vulnerable?
30 degrees flexion
How is arthrokinematics different in the knee?
Open chain concave tibia on convex femur, same direction
Closed chain convex femur on concave tibia, opposite direction
When does the locking mechanism occur?
Final 30 degrees extension
What 4 things could cause lateral glide of patella?
Overactive VL
Tight ITB
Shallow trochlear groove
Genu valgus/femoral anteversion increasing Q angle
What 2 things could cause medial glide of the patella?
Weak/delayed activation VMO
Stretched medial retinaculum
What 2 things could cause lateral tilt of the patella?
Tight ITB
Overactive VL
What 2 things could cause medial tilt of the patella?
Ruptured or stretched medial retinaculum
Loss of tone VMO
What is the Q angle and when does it increase?
Angle formed by a line between the ASIS and patella, and tibial tuberosity and patella
It increases with genu valgus, femoral anteversion and external tibial rotation
What is the difference between joint effusion and hemarthrosis?
Effusion- gradual onset, worse next morning, synovial irritation or inflammation
Hemarthrosis- rapid 1-2 hours, blood
What does it mean if walking downstairs is an aggs?
Patellofemoral pain syndrome as quads are in more control
What forces damage the MCL and LCL?
Valgus- MCL
Varus- LCL
When is the ACL injured?
Hyperextension
Decelerating, pivoting with some flexion
When is the PCL damaged?
Forced hyperflexion
What movements cause supination?
Inversion, adduction and plantarflexion
What movements cause pronation of the foot?
Eversion, abduction, dorsiflexion
Break down the subtalar joint?
Posterior joint: Convex calcaneal dome on concave inferior talus, calcaneus fixed in weight bearing
Anterior joint: concave calcaneal facets on convex inferior talar surface, calcaneus fixed in weight bearing
Which ligament is most commonly injured in inversion?
Anterior talofibular ligament (ATFL) (inversion/plantar flexion)
Calcaneofibular ligament less so (inversion/dorsiflexion)
What are some modifiable risk factors for lateral ankle sprain?
Reduced dorsiflexion ROM
Reduced proprioception
Body mass index
When is the posterior talofibular ligament injured?
Dorsiflexion/external rotation
When is the MCL of the foot injured?
Rarely injured but can in eversion/pronation
Which arch is higher and takes more weight bearing?
Medial
What does foot pronation help with?
Mobility: Shock absorption, changing direction
What does foot supination help with?
Stability
What does cavus/planus mean?
Cavus = supination
Planus = pronation
What does calcaneovarus and calcaneovalgus mean?
