Hi all,
Thanks to everyone who have answered and provided wonderful suggestions for the steady stream of questions that many of us post on this site.  It's a great way for us to all contribute to eachother. 
 
I have another situation where I could use some help.  I am refitting a prosthesis on a very active 77 year old woman who recenlty fractured her distal femur on the amputated side.  After convincing the surgeon to not simply make her an AKA, she is healing well after ORIF.  She is now ready for refitting because the limb is larger and the knee alignment has changed. 
 
Interestingly, prior to the fracture she had a significant amount of valgus in the knee.   We were able to align the prosthesis with the valgus but when the knee was rodded and pined, the surgeon did not know about the valgus and set the leg in such a way that the knee is now in neutral. 
 
She has a fair degree of osteoporosis and she may have twisted in the prosthesis.  I would like to reduce the shock and rotation stress in the leg by providing a shock / rotation unit.  She is not very big and something like the Ossur Reflex Rotate would be quite heavy for her.  Any suggestions for a very light weight rotator with or without vertical shock? 
I have 10 inches to work with from the distal lock pyramid to the floor.  Thanks again to anyone who has any suggestions.
 
Sincerely,
Karl W. Entenmann, CPO
