As i just checked past correspondence it turns out that I had written to the sales contact of Ossur Europe on December 14th 2009.
I had informed them their product Ossur Upper X (which I was equipped with) causes me both eczema at the stump end and, furthermore, constriction of my arm at the elbow – simply because they mass produce stump liners for cylindrical shape rather than my real stump shape which obviously is more conical.
In other words, their liners fit a stump that has the same circumference at any position (cylindrical shape) – whereas my stump is a bit more muscular, thick and wide at the elbow and thin and bony at the end (conical shape). That is the case because I am very active and keep fit, because I move a lot and do sports.
Now, Ossur advertises to be “the go-destination for athletes that want to be active” but that is not met by their products – the liners are geared towards amputees that, in fact, have cylindrical stumps. Legally, Ossur cannot be held responsible as they advertise to be a manufacturer for people that “want to be” active much rather than catering towards people that actually “are” active.
So given all that, I had asked them to produce the liner with a conical shape.
More specifically, I had written them the following text (in German, just for the record):
Mit dem Upper X Groesse 14, der vorne am Stumpf zu locker ist, habe ich nun vorne am Stumpf deswegen kleine Taschen, in denen der Schweiss sammelt und wo die Haut daher zu Ausschlag, Pilzinfekt und Ekzem neigt. Am Oberrand neben dem Liner ist dieser viel zu eng, dort habe ich vom starken Druck auch schon kleine Blasen gehabt.
Daher meine Bitte: – koennten Sie die Upper X Liner alternativ leicht konisch anbieten, vorne beim Pin sollte er etwas enger sein als hinten
In other words, I explained serious dermatological consequences of their liner design.
Rather obviously, I never got an answer.
