Ossur customer service appears to have no time, Ossur Facebook censoring removes relevant request posts - so the company must do their darnedest to create the impression that their parts function and customers happy. It is indeed possible to work with Ossur parts though, despite what definitely comes across as questionable attitude and questionable engineering.
The system that I was set up with to use contains
- Ossur Upper X silicone liners, and
- Ossur Icelock pinlocks used for prosthetic arms (Icelock UX 721 and similar)
Both are problematic and yet, prices are massive.
This post is about the pinlock.
