GENERAL PROSTHETIC QUESTIONS FOR
ABC WRITTEN EXAM QUESTIONS AND
ANSWERS UPDATED (2024/2025)
(VERIFIED ANSWERS)
Pressure on Scarpa's Triangle provides - ANS ✓-relieves pressure at initial
contact
-comfort for sitting
-relieves the ADDUCTOR longus tendon
-controls rotation
-keeps pelvis from rotating
-IT on the seat
Anterior-posterior forces - ANS ✓-concentrated in the anterior distal tibia and
posterior proximal soft tissue
-Socket provides even pressure distribution in the popliteal area and anterior
distal relief to prevent excessive pressure
Media-lateral forces - ANS ✓-forces at the proximal medial and distal lateral
area force a varum moment at midstance
-Socket must have relief for the distal lateral fibula and lateral stabilizing
pressure over the shaft of the fibula and anterior compartment.
Sheer force - ANS ✓-Occurs when the socket moves in a direction opposite to
the residual limb's motion.
Torque - ANS ✓-Tendency of the socket to rotate on the residual limb

Joint Location for TT J&C designs - ANS ✓-2 1/4" inches superior to the patella
tendon protuberance, and slightly posterior to the sagittal midline.
-joints must be square to each other and an equal height from the floor
-line through JCs would be roughly perpendicular to LOP
-slight anterior tilt
-extension stop strap can prolong joint life.
Corset Location and Configuration - ANS ✓- generally 8" long
-Proximal lateral border 1" higher
-Anterior distal edge is proximal to patella
-opening is 1" wide
- When sitting tissue should not be pinched between proximal socket wall and
distal corset aspect. 1" clearance needed.
Voluntary Opening TD - ANS ✓-Closed at rest
-Body motion and effort used to open TD
-Max force regulated by the # of rubber bands or springs (1 rubber band = 1lb of
pinch force)
-requires 2 1/2 times the pinch force to open the TD
Voluntary Closing - ANS ✓-Open at rest
-Body motion and effort used to close the TD
-Max force regulated by the patient effort and the mechanics of the device
-requires user to overcome the spring/elastic cord

NYU-Muenster - ANS ✓-A-P compression
-short to very short limbs
-light to moderate duty
-unilateral
-LL =1 1/2" to 5 1/2"
-achieve 70* ROM from 35* to 110*
Northwestern Design - ANS ✓-Supracondylar suspension
-low anterior timelines
-longer limbs, greater than 55%
-good for bilaterals
Otto Bock - ANS ✓- mid range limbs
-M-L & A-P compression
-dynamic casting technique
Elbow Flexion Attatchment Adjustment - ANS ✓-more proximal = less
required excursion
-more distal = less required force
Proximal Base Plate Retainer - ANS ✓-more posterior and distal = less
required excursion
-more proximal and lateral = less required force
-must be 25mm proximal to the cut end of the humerus
Cable Housing and Length - ANS ✓-Cable Length -- extend arm and pronate TD
(3mm clearance between hangar and proximal housing)
