TT Troubleshooting

Question 1

Lateral & distal redness

Answer 1

• socket too large

* add socks, or pads

Question 2

Proximal lateral & Distal medial redness

Answer 2

• adducted socket
• abduct socket
• socket ML too large
• add ML pads @ condyle
• foot too outset
• inset foot

Question 3

Anterior proximal & posterior distal pressure/redness

Answer 3

• insufficient initial socket flexion
• shoe change w/ decreased heel height
• heel lever too short / toe lever too long
• heel bumper cushion too soft

Question 4

Patient bottoming out/vericose hyperplasia

Answer 4

• Pt decreased limb volume
• inappropriate sock ply
• socket made too big initially
• lack of distal contact

Question 5

Fib Head Redness

Answer 5

• greater proximal pressure than distal pressure
• inadequate relief built into socket
• inappropriate donning of liner

Question 6

Anterior Pain/pressure & distal lateral pressure (heel of pt is off the ground)

Answer 6

• insufficient socket flexion/PF foot (causes pt to hyperextend in stance so the compensate with hyperflexion
• Flex socket

Question 7

Proximal medial pressure & distal lateral pressure

varus moment

Answer 7

• foot too inset
• socket too abducted
• shift socket medially
• adduct socket

Question 8

Distal medial pressure, proximal lateral pressure

valgus moment

Answer 8

• foot too outset
• socket too adducted
• shift socket laterally
• abduct socket

Question 9

Proximal patella pain, distal posterior pain

pt toe coming up on midstance

Answer 9

• foot too anterior/socket too posterior to foot
• heel cushion too soft
• move socket forward
• add firmer heel wedge in px foot

Question 10

Anterior distal tibial pressure

Answer 10

• AP too big
• posterior brim too low
• insufficient relief
• excessive use of knee extension
• heel lever too long
• excessive initial socket flexion
