Without seeing the person with the prosthesis it is impossible to accurately
diagnose this particular condition. This sounds very much like subcutaneous
cyst formations. My experience has shown that socket designs that emphasize
high proximal A-P compression (typical of exaggerated PTB designs) cause
soft-tissue compression/stress posteriorly just inferior to the socket
margin. Just superior to the socket margin is a very low pressure condition.
The transition area is where the cyst problems typically occur - from
extravasation of fluid from high pressure to the low pressure area.
(this can be complicated by a residual-limb that has a reduced surface area
for weight-bearing, causing the socket design to increase the compression
posterior proximal). I would seriously evaluate socket design - or find a
Prosthetist who can accurately evaluate socket design to rule this out
first. An alternative is to instruct the amputee to not wear the prosthesis
for one-three days. If the area improves, there is a good indication that
socket design is the causal factor.
