MT: Intro to Bench

Question 1

Socket Ab/Adduction

Answer 1

• Adduction can accomodate more loading
• most pt will be adducted
• socket in AD we put hip AB on stretch

Question 2

Reference Points

Answer 2

• midsagittal mark: center of lateral wall
• mid coronal mark: at center of anterior or posterior wall

Question 3

Socket Position: Rotation

Answer 3

• orient the socket so that the LOP determined during static alighment is parallel to the foot plate
• posterior wall of the NURIC socket should be perpendicular to the LOP

Question 4

Socket Position: Angular

Answer 4

• sagittal plane we will increase the flexion by 5 degrees
• put hip extensors on stretch for loading response

Question 5

Linear Position: sagittal plane

*

Answer 5

• weight line (sagittal bisector) most times should be anterior to knee axis of rotation
• placing knee/foot more anteriorly reduces stability

Question 6

Linear Position: Coronal Plane

Answer 6

• weight line (bwteen coronal bisector and IT) should go through center of knee unit
• Positioning knee/foot more medially reduces stability

Question 7

Linear Position: Transverse Plane

Answer 7

knee unit should be externally rotated 5 deg

Question 8

Why position knee/foot more laterally

Answer 8

• shorter RL
• larger patients
• weaker abductors
