Alpha liner problem

Alpha liner problem

Listservers,

I could use some input on this situation:
I am seeing an amputee who has a long, mature AKA with a normal shape,
with no unusual crevices or contours. I'm using a lanyard system with
the exit through the lateral/distal wall of the socket and frame. I'm
having problems with gel cracking/splitting (~5mm) on the medial seam,
at the junction of the umbrella attachment. This, in turn, leads to air
wicking through the fabric, creating a pocket of air in the liner. Type
of liner: I've used 3mm Original and Spirit locking Alpha liners. The
liner size is appropriate.

My guess is the side-pulling of the liner is causing the problem, but
I've done these previously without this problem. Thinking pistoning and
lack of distal contact may be the problem, I've tried gel endcaps, and
distal pelite pads to no avail. The socket fits well.
Any ideas? Thanks in advance.
