LE Joints Rest Position and Concave/Convex

Question 1

Hip

Answer 1

Rest: 30 degrees flexion, 30 degrees abduction, slight lateral rotation

Convex: femur
Concave: acetabulum

Question 2

Tibofemoral

Answer 2

Rest: 25 degrees flexion

Convex: femur
Concave: tibia

Question 3

Patellofemoral

Answer 3

Rest: 25 degrees flexion

Convex: patella
Concave: femur

Question 4

Proximal Tibiofibular

Answer 4

Rest: 0 degrees plantar flexion

Convex: tibia
Concave: fibula

Think of concave fibular head at top

Question 5

Distal Tibiofibular

Answer 5

Rest: 0 degrees plantar flexion

Convex: fibular
Concave: tibia

Think of concave fibular head at top, opposite here

Question 6

Talocrual

Answer 6

Rest: 10 degrees plantar flexion, midway between maximum inversion and eversion

Convex: talus
Concave: tibia and fibula

Question 7

Subtalar

Answer 7

Rest: midway between extremes of ROM

Convex: anterior and middle talus (JUST REMEMBER THIS, THE ANTERIOR+MIDDLE TALUS LEADS THE WAY AND STICKS OUT)
Concave: anterior and middle calcaneus

Convex: posterior calcaneus
Concave: posterior talus

Question 8

Intermetatarsal

Answer 8

Rest: midway between extremes

Convex: more medial metatarsals
Concave: more lateral metatarsals

Question 9

Metatarsophalangeal

Answer 9

Rest: neutral

Convex: metatarsals
Concave: phalanges

Question 10

Interphalangeal joints of toes

Answer 10

Rest: slight flexion

Convex: proximal phalanges
Concave: distal phalanges
