Hello, I am 53, have had PD for almost 20 years, and had total hip replacement surgery this past year--it was the pit of my life. My PD has been well managed all these years. I do almost everything I want, and have recovered many things that I couldn't do for awhile. I'm on low doses of meds: 2 25/100 Sinemet 8 to 10 Permax 1 Eldepryl 2 Amantadine per day. About two years ago a galloping inflamatory process started up in my right hip (my PD is on the rt. side only). There had been some arthritic changes and pain for several years prior. Within two years I could no longer walk or sleep at night for the pain. I had a series of cortizone injections that helped only slightly at first, and I think then precipitated a rapid decline, although no one else will admit to this. I think my joint became necrotic because of a combination of incoordination, PD changes, and cortizone. No one confirms this among my "caregivers." Sept. 14 a year ago, I had hip relplacement surgery--no cement. Two months later I began to dislocate--four times total. Each time the muscles lost strength, tone, and were damaged. December 14 I had a second surgery. This time a captured cup joint with screws, and I presume cement was inserted. My spasmy pyrformis muscles was also loosened. I spent four months in a body brace with crutches to get the joint stable. In April when I quit the crutches my abductors were all atrophied as well as the hip flexors, and the muscles of my trunk were very weak. I have always exercised and been in good shape. This was horrible for me. Despite my doctors advice I have been doing nautilus, and with his advice I have been swimming. My strength is returning, and I'm finally feeling better than I have in two or three years, although there is still weakness in those muscles and I will be working on this for some time to come. I also think that the intubation from the second surgery damaged my vocal chords, so I'm working on that too. I have posted on the Internet and the PD Bulletin Board for other peoples" experiences with this--there was no answer from a YPD with this problem.. The medline have very little on it as well. I am glad I did it. I probably would have become bedridden and be dead by now from pneumonia and other complications. However, I would suggest the most secure joint possible. One can regain muscle strength and tone from lack of movement. The vissitudes of rigidity, dystonia, etc. make the muscles surrounding the joint an unstable source of strength for a new joint. I hope this helps, and I wish my doctors and I had known about this before I went through those horrible dislocations that really undid me emotionally for a couple or three months. One finaly bit of advice is that you make sure your doctors are talking to each other. They don't like to take the time to do that, despite all the business about "team approach" etc. They don't talk and they don't know everything there is to know. Orthopedists don't know about neurological disorders, and neurologists don't knwo about mechanical matters. They protect themselves and each other--even the best of them, and I like my doctors very much. They also tend to get tunnel vision about people with a diagnosable phenomenon - PD - and attribute everything to that no matter what it wrong. Get second opinions. Good luck. Feel free to write or call me if you want to talk about it more. Claudia Elliott 1915 N. Wolcott Chicago, Ill. 60622 312-489-3607
