Hello to everyone on the list. I am a former member of this list returned. For quite a time these conversations were utterly useful and I was grateful for this forum. I left after awhile just to give my mailbox a rest. However now I return with new necessity so I'll reintroduce myself saying once again how glad I am to have this resource available. I am 55 years old and have had PD since age 35. It has been a slowly progressive version which has ennabled me to adapt and retrain body memory over time in such a way that I could regain many of my losses of function. With the help of medication I have been able to function pretty much normally in my life. However in 1994, a severe attack of pain in my hip innitiated a process that I am still living out. Deterioration in my hip joint led to a total hip replacement, which began dislocating two months later, and had to be revised 3 months later. The revised joint captured the ball in the socket so that it couldn't fall out. As a consequence, it took three years for the dislocation to begin occuring in the form of pulling the socket away from the bone. This past August intense pain led to another revision with a five-screw insertion of a new socket which, within weeks began to dislocate. At present I am scheduled for a revision this coming week which will include an acetabular ring, I believe. My experience with this problem has been that no one understands the dangers until they have already occurred, so that we keep haviing to learn from mistakes rather than the experience of others. My participation in this forum the last time, turned up one or two people who had had hip replacements, and the literature has nearly nothing. I find nothing current on the internet. The problem has to do with the erratic firing of PD neurons and the unpredictable muscle changes that result. Things that appear stable on the surface on inherently unstable. Somehow there must be some way to systematically understand this combination of problems to prevent the repetition of this carnival of errors. Therefore, I want to ask all of you if there is anyone with a similar experience on this flist, or that you might know. Any input would be great. Thanks to all of you. Claudia Elliott Chicago, Ill.
