Hip: flexion

Lumbar spine: extension

45
Q

Posterior tilt effect on hip and back

A

Hip: extension

Lumbar spine: flexion

46

why use cane on contralateral side?

A

substantially less total joint force compared to ips side

47
Q

LE Closed Chain Pronation

A 
Femoral: IR
Knee: flexion
Tibia: IR
Talus: PF and add
Calc: eversion
*shortens limb
48

Closed: 10deg of IR of femur in last 30deg ext

50
Q

what is the screw home mechanism driven by?

A

shape of medial femoral condyle
passive tension of ACL
lateral pull of quads

resists valgus and extension forces

clip injury

52
Q

LCL fxn

A

resists varus and extension forces

53
