AMPUTATION-PTB SOCKET PROS & CONS

SUMMARY

PROS
1. Accommodates various stump shapes.
2. More accommodating of volume changes: can be selectively packed with additional padding.
3. Designed to accommodate the dynamic changes in pressure through the gait cycle.
4. Gait can look essentially normal except for the lack of plantar-flexion/push-off.
5. Cosmetically acceptable than thigh lacer prostheses, and easier to don.

CONS
1. “Round peg” in a triangular hole: risk of pressure/constriction of the stump.
2. Localized areas of pressure may contribute to vascular compromise, eg. popliteal area, anterior distal tibia.
3. Risk of skin irritation due to shear forces over high pressure areas.
4. Relief may allow areas for dependent fluid build up.
5. May not provide a sufficient sense of stability.
6. The popliteal shelf must sit equal or higher than the patellar tendon bar in order to provide counter-pressure, and can cause irritation to skin and limit knee flexion range for sitting and stairs mobility.
7. Patients complaint of pressure in the popliteal fossa and over the patella.
