Guest guest Posted January 19, 2004 Report Share Posted January 19, 2004 You make the statement that surface replacement does not have long term research to prove that it is better than THR. Then you say that " hearing that a THR could last 35-40 years is encouraging " doesn't make sense. There is over ten years of results from hip resurfacing that shows great success. Something that " could " give you 35-40 years in the form of SROM-THR has a long way to go before it proves itself to be real. You also state that " previous surface devices were not good. " Most of these early failures were in the US because they didn't get the materials in the right combination as the Birmingham scientists did with far less early failures. In any case the early failures paved the way for the fabulous results that I and many other surface hippies have been enjoying for a long enough time. The failure rate for resurfacing is far less than THR as you can research in our archives. Believe me, if anything has a chance to last 35-40 years it will be a hip resurface device, not a THR. Of course I'm talking about the procedures in general. I know that there have been isolated cases of THR's that have lasted an extraordinarily long time, but on the whole they cannot compare to the percentages of success of resurfacing-not to mention the obvious superiority in holding up in the stresses of impact sports.

Guest guest Posted January 19, 2004 Report Share Posted January 19, 2004 By recommendation of my Phy Therapist and Chiropractor I went to see Dr. Sampson in S.F. In runs a clinic and performs many THR a year. He said he has his refined his method and felt a THR with a SROM could last me my lifetime. He says the method and experience of the sugeon was very important in success and the device had many years of research to support it. Wondering what others think of this. Having 1 surgury to last a lifetime even without some expectations surface replacement hopes for seems very desirable. I would appreciate hearing thoughts and this. thank you kindly happeehip Quote Link to comment Share on other sites More sharing options...

Needless to say it was very enlightening and convinced me that hip resurface was the way to go. My THR OS never did this. The THR device will never give you the range of motion that the hip resurface gives you and you will always have to worry about dislocation. There are MANY reasons why the hip resurface is superior to THR. Do your research and believe what is written about hip resurface. It is not too good to believe but is really is a wonderful device which all on this site will attest to. Also, quality of life is important to us all which is why I got the surgery and continue to post and encourage others to get the hip resurface if possible.

Guest guest Posted January 20, 2004 Report Share Posted January 20, 2004 Jeff: I believe the Conserve Total Hip System with the Big Femoral Head provides almost the same range of motion as a resurface - both are metal on metal. I believe the same is true for the other metal on metal THR systems since the size of the femoral head is the key to range of motion. > > By recommendation of my Phy Therapist and Chiropractor I went > > to see Dr. Sampson in S.F.

Guest guest Posted January 20, 2004 Report Share Posted January 20, 2004 I really hope that this talk about THR's not lasting as long as resurfacing does not include the new MOM THR. I unfortunately had to have a revision of my resurfacing after 15 months due to the development of AVN under the cap. I went in for exploratory and came out with the Corin component large ball MOM. My cup was in great shape and did not have to be replaced. At first I was not happy. I really believed that loosing my resurf meant disaster for me. After three weeks I am very encouraged. I have no more pain except a bit of soreness, and my recovery time has been minimal. I still need to follow the 50% weight rule for six weeks, but after that I can do what ever I feel I can do. My surgeon told me that he believes that my THR will have as long a life as the resurf. I looked at him in the eye and asked him if he was being totally truthful or if he was trying to make me feel better and he again stated that this is what he believes. I know of several others on this list that have also had revision to a THR and are very happy with the result. I believe all of these revisions are the large headed component made by Corin or the C+. Please let us not dismiss the possibility that this new large headed MOM THR may be a winner and that it may be the best choice for some people. I will have to have another surgery for my left hip and becasue of my experience will go right to the THR. I put faith in my surgeon, Dr. Stachniw, and believe him about the longevity of the device I have. This baby I have right now is going to last my lifetime.......I just feel that it will.

Guest guest Posted January 21, 2004 Report Share Posted January 21, 2004 Hi Jan Hope you're making progress with your research - I know how stressful it is when you're aware of the impact this decision has on what your life will be like. One point you should bear in mind when comparing THR and resurf is that even if the 2 devices last for the same number of years,there are significant differences when it comes to revision. At least with a resurf your bone is conserved. Good luck! Kathy > I really hope that this talk about THR's not lasting as long as resurfacing > does not include the new MOM THR.

Guest guest Posted January 21, 2004 Report Share Posted January 21, 2004 I think it is a good idea to believe that nothing lasts a lifetime. What better proof then our own darn hip/s that gave out with OA or AVN or other problems? Even we, mortal beings, have a lifespan that runs it's course when destiny says it must. THAT said, let's all be hopeful that our respective devices (ahem, now that we are a tad older) might perhaps last as long as our own personal end. I say this with optimism, not grimness. While I have a resurf, I was just a breath away from a large head MOM. I have to say I honestly didn't care. While the resurf was my first choice, the THR large head was my second. What was the most important issue? That I get something wonderful and extraordinary that was going to give me back quality of life. I totally put my trust in G-d and a excellent surgeon and I promised to do my part with exercising, following the precautions and helping my body heal. I repeat again....getting back quality of life is primary. No one can predict the exact future whether it's the stock market or the weather. When it comes to body part implants all one can do is select what seems to be the best part as well as an excellent surgeon. Sometimes " things happen " and we don't know until we get there. I would still choose resurf first, but other choices are great too. However, logic and research tells me that resurf makes the best sense, with large ball MOM available if resurf isn't a possibility.

Guest guest Posted January 21, 2004 Report Share Posted January 21, 2004 Happeehip, There are some things you need to bear in mind: 1) How long a hip lasts depends on a lot of factors, not the least of which is how much you do with it. We have triathletes, runners, climbers, martial artists, etc. here. If your idea of vigorous activity is actually getting up out of your chair to change channels rather than using the remote, then pretty much *any* hip will last a long time. Ask your doc about post-recovery activity restrictions. I really doubt if he'll tell you it's okay to ski moguls. ;-) To my knowledge, no resurfacing has *ever* " worn out " . They've failed for other reasons (although still at a much lower rate than THRs), but they've never worn out. Go to the Midland web site (the folks who make the BHR). Look at 's case study. He won the World Championship in Judo in his age division five years after a resurfacing. He's still competing at a world-class level (9 years post-op). Ask your doc how many SROM patients are world-class athletes 9 years after a THR. Ask for their *names*. 2) While it's certainly true that BFH (that's big FEMORAL head) metal-on- metal THRs have many of the advantages of resurfacing (low wear, more natural range of motion), the SROM-THR is not such a device. It is a modular metal-on-plastic or ceramic-on-plastic (depending on which head you select) device. The largest head size available for the SROM is 32mm. BFH and resurfacing typically run about 50mm, and they're available in sizes even larger than that. The larger head provides two major advantages: a) better range of motion Reduced risk of dislocation. The clinical data available suggests that resurfacings and BFH MoM THRs are 50 to 100 *times* less likely to dislocate than a metal-on-poly THR The metal-on-metal articulation in both these devices produces much less wear, and hence less debris, than a conventional metal on polyethylene articulation. One of the major causes of failure in conventional (metal-on-plastic) THRs is osteolysis - a loss of bone around the implant due to inflammation caused by (plastic) debris. To my knowledge, there's never been a reported case of debris-induced osteolysis in a resurfacing or BFH MoM patient. 3) According to the manufacturer's website, the SROM has been on the market for 10 years and has been implanted in 15,000 patients. That's actually roughly the same as the BHR. Based on that, I don't think it's reasonable for *anyone* to claim that the SROM will " last a lifetime " . I'm sure it's a fine product, but there's just no basis for such a claim. If you want comparative data for resurfacing and THR, you might want to check out the Swedish Hip Register data for implant survival in patients under age 55. It's a real eye-opener. 4) If you have a resurfacing and it fails (unlikely, but it happens), you can *always* get a *primary* (as opposed to a *revision*) THR. Primary THRs have a higher success rate than revisions. If all the resurf does is save you a revision later in life, you will still have done yourself an enormous favor. THRs, on the other hand, cannot be revised to resurfacings. Once they've cut the head off your femur, it's *gone* and there's no going back. 5) All THRs (even BFH MoM) suffer from a problem called " proximal stress shielding " . This causes bone at the top of (what's left of) your femur to atrophy and weaken, which contributes to loosening of the stem. This is caused by the way load is transferred in a THR (down the metal stem into the center of the femur) versus a natural or resurfaced hip (compression on the outside of the bone), and your body's natural response to this (which is to strengthen bone that's subject to load and to weaken bone that isn't). 6) Recovery from a resurf is typically 2 to 3 times faster than a THR Resurfacing is not without its risks: you need good bone quality and it's possible that the procedure may damage the head of the femur in ways that will cause the implant to loosen. A couple of people here have had this happen, but the incidence of these problems has declined dramatically as surgeons have become more experienced. The incidence of resurfacing failures is *lower* than the incidence of THR failures - and when such failures occur they can be revised to a primary THR. It's your hip, and it's your decision. You owe it to yourself to research this carefully, because you'll be stuck with the consequences for the rest of your life. If I were you (and I'm not, of course), I'd find out if I was a candidate for a resurfacing before I committed to a THR. If not, I'd see if I could get a BFH MoM THR. Just my 2 cents worth.

My $.02 here: Pre-op I could not move for a couple of years and had marked loss of bone in the hip and thigh (no or weird loading = bone loss). At the 2 year mark I had a bone density scan and even though part of the hip was obscured by the implant, I had actually increased my bone density significantly ( meaning I was back in line with a normal thigh, rather than falling out the bottom of the normal range). Some years back I had much thicker thigh bones than most folks because I did long distance running. The unoperated side still has much thicker bone than the operated side. I'm just happy that my risk of fracture is more in line with the general population now. --> No I did not take Fossamex (sp?) just calcium supplements and I make it a point of walking 2 miles a day during the week (1 mile each way to and from work). I am otherwise quite active too, so your mileage may vary. Bottom line, yes you should take Steve's claim quoted above seriously! -- Jeff rBHR Aug. 1, 2001 Mr. McMinn ================== " Rudeness is the weak man's imitation of strength.

Guest guest Posted January 22, 2004 Report Share Posted January 22, 2004 hi- ---------------------------------------------------------------------------- steve, wonderful overview of the hip resurf rationale, in one page you touch on it all.....it should be a flyer to send all new people who have managed to stumble across this goldmine of a message board. --------------------------------------------------------------------------- happeehip- trust me, you'll really be a happy-hip after you get your " new " hip. i think it's important for you to realize that YOU are in the driver's seat on this issue. you have the benefit of the fact that your hip condition is not an emergency......it's just that it is necessary, and is on the horizon. this means that you have the luxury of some time to investigate all your options.....as you are obviously doing. i'm sure that your doctor's favorable demeanor is comforting to you as you have probably been dealing with the way that your hip is affecting your life. my advice is simply " don't sell yourself short " because you allowed yourself to be easily led by the words of any guy with " Dr. " in front of his name. scrutinize and compare, you have nothing to lose and much to gain. there is a whole lot of information here, and it's all free and at your fingertips. i'm sure you wouldn't buy the first car that the first salesman showed to you. and, if it's the wrong car, you can't just trade it in for a new one. bedside manner doesn't have anything to do with experience, skill and intelligence......but those things have alot to do with a succesful surgery. happy shopping, jeff lbhr desmet (65 days ago and giggling about it) Re: SROM-THR lasts a life time Happeehip, There are some things you need to bear in mind: 1) How long a hip lasts depends on a lot of factors, not the least of which is how much you do with it. We have triathletes, runners, climbers, martial artists, etc. here. If your idea of vigorous activity is actually getting up out of your chair to change channels rather than using the remote, then pretty much *any* hip will last a long time. Ask your doc about post-recovery activity restrictions. I really doubt if he'll tell you it's okay to ski moguls. ;-) To my knowledge, no resurfacing has *ever* " worn out " . They've failed for other reasons (although still at a much lower rate than THRs), but they've never worn out. Go to the Midland web site (the folks who make the BHR). Look at 's case study. He won the World Championship in Judo in his age division five years after a resurfacing. He's still competing at a world-class level (9 years post-op). Ask your doc how many SROM patients are world-class athletes 9 years after a THR. Ask for their *names*. 2) While it's certainly true that BFH (that's big FEMORAL head) metal-on- metal THRs have many of the advantages of resurfacing (low wear, more natural range of motion), the SROM-THR is not such a device. It is a modular metal-on-plastic or ceramic-on-plastic (depending on which head you select) device. The largest head size available for the SROM is 32mm. BFH and resurfacing typically run about 50mm, and they're available in sizes even larger than that. The larger head provides two major advantages: a) better range of motion Reduced risk of dislocation. The clinical data available suggests that resurfacings and BFH MoM THRs are 50 to 100 *times* less likely to dislocate than a metal-on-poly THR The metal-on-metal articulation in both these devices produces much less wear, and hence less debris, than a conventional metal on polyethylene articulation. One of the major causes of failure in conventional (metal-on-plastic) THRs is osteolysis - a loss of bone around the implant due to inflammation caused by (plastic) debris. To my knowledge, there's never been a reported case of debris-induced osteolysis in a resurfacing or BFH MoM patient. 3) According to the manufacturer's website, the SROM has been on the market for 10 years and has been implanted in 15,000 patients. That's actually roughly the same as the BHR. Based on that, I don't think it's reasonable for *anyone* to claim that the SROM will " last a lifetime " . I'm sure it's a fine product, but there's just no basis for such a claim. If you want comparative data for resurfacing and THR, you might want to check out the Swedish Hip Register data for implant survival in patients under age 55. It's a real eye-opener. 4) If you have a resurfacing and it fails (unlikely, but it happens), you can *always* get a *primary* (as opposed to a *revision*) THR. Primary THRs have a higher success rate than revisions. If all the resurf does is save you a revision later in life, you will still have done yourself an enormous favor. THRs, on the other hand, cannot be revised to resurfacings. Once they've cut the head off your femur, it's *gone* and there's no going back. 5) All THRs (even BFH MoM) suffer from a problem called " proximal stress shielding " . This causes bone at the top of (what's left of) your femur to atrophy and weaken, which contributes to loosening of the stem. This is caused by the way load is transferred in a THR (down the metal stem into the center of the femur) versus a natural or resurfaced hip (compression on the outside of the bone), and your body's natural response to this (which is to strengthen bone that's subject to load and to weaken bone that isn't). 6) Recovery from a resurf is typically 2 to 3 times faster than a THR Resurfacing is not without its risks: you need good bone quality and it's possible that the procedure may damage the head of the femur in ways that will cause the implant to loosen. A couple of people here have had this happen, but the incidence of these problems has declined dramatically as surgeons have become more experienced. The incidence of resurfacing failures is *lower* than the incidence of THR failures - and when such failures occur they can be revised to a primary THR. It's your hip, and it's your decision. You owe it to yourself to research this carefully, because you'll be stuck with the consequences for the rest of your life. If I were you (and I'm not, of course), I'd find out if I was a candidate for a resurfacing before I committed to a THR. If not, I'd see if I could get a BFH MoM THR. Just my 2 cents worth.

The alignment of the artificial piece that replaces the femoral head in a THR will hit the sides of the cup when the joint is radically bent which causes a slightly less range of motion to be available for the person that has the THR versus the BHR. I believe he was saying approx. 135 degrees versus 180 degrees range of motion. I don't want to be passing along incorrect data though so I'm curious what you saw from a demonstration of the joints pieced together in the bone structures and moved around in 180 degree type contortions from one side to the other. With the small pin on the bottom of the hip resurface there is basically no limiting range of motion versus the artificial femor head causing this problem of hiting the side. However, with all this said as you stated possibly I was looking at a small head femoral head versus the big femoral head but I don't believe so. Also, the metal on metal is key either way you go and the fact that the THR has the potential to loosen up in the femor with jumping and other activites that more active people do I definitely would get a second opinion before going right into a THR.

Guest guest Posted January 22, 2004 Report Share Posted January 22, 2004 I continue to be amazed at what I read from this group. The generalizations and the statements of fact are just preposterous, 5) All THRs (even BFH MoM) suffer from a problem called " proximal stress >Â Â shielding " . This causes bone at the top of (what's left of) your femur >Â Â to atrophy and weaken, which contributes to loosening of the stem. >Â Â This is caused by the way load is transferred in a THR (down the >Â Â metal stem into the center of the femur) versus a natural or resurfaced >Â Â hip (compression on the outside of the bone), and your body's natural >Â Â response to this (which is to strengthen bone that's subject to load >Â Â and to weaken bone that isn't). How can anyone make this statement. " All " " Lifetime " " Never " " Best " should not be used in any statements about hip replacements. There is no perfect procedure for everyone. The only perfect procedure is one that bring a quality of life back to oneself. It may be Resurfacing or THR. Not everyone is a candidate for resurfacing and there are other good options. For someone who is not a candidate for resurfacing than THR can give that person the same benefits as resurfacing. I am one who has a MOM large ball THR that I have concluded is better than the resurfacing that I received. For the few people who wrote the above I must bring you back to reality and remind you that the femur ball on a resurfacing is cemented. My cement lasted one year!
