Problemi di sostituzione del cinorrodo

Come con tutti gli ambulatori importanti, una procedura della sostituzione del cinorrodo è associata con parecchi complicazioni e rischi, alcuni di cui possono anche essere pericolosi. Il rischio di complicazioni è basso, ma alcuni esempi dei problemi potenziali includono:

  • Dislocazione della giunzione
  • Allentamento della giunzione
  • Usura
  • Irrigidimento unito
  • Coagulo di sangue
  • Infezione

Giunzione di lussazione dell'anca

L'articolazione dell'anca è spostata dal suo socket dentro intorno 3% dei casi. Dopo una procedura della sostituzione del cinorrodo, può prendere a dodici settimane per i tessuti molli intorno alla giunzione per guarire dopo che sono stati tagliati durante la chirurgia. Durante questo periodo, la giunzione è supportata male e la testa femorale può funzionare esente il suo modo dal socket, piombo alla dislocazione. Il rischio di lussazione dell'anca è diminuito quando meno tessuto è tagliato, se il tessuto del taglio è riparato o se la protesi capa femorale ha un grande diametro. Quando le teste con un più di diametro basso sono utilizzate, le tariffe più basse della dislocazione inoltre sono vedute con l'anteriore piuttosto che l'approccio posteriore a chirurgia, ma questa ancora non è stata dimostrata per le procedure che comprendono le teste con un più grande diametro. I pazienti possono fare diminuire il loro rischio di dislocazione evitando determinate posizioni durante le prime parecchi mesi che seguono la chirurgia. L'uso dell'alcool nei pochi mesi che seguono la chirurgia è associato con un rischio aumentato di dislocazione.

Allentamento della giunzione

Ciò è la complicazione più comune della sostituzione del cinorrodo ed accade quando l'asta cilindrica della protesi diventa sciolta nel socket dell'osso della coscia o dell'osso che circonda gli inizio dell'innesto assottigliarsi. Ciò può piombo per fare soffrire e una sensazione che la giunzione è instabile. Se la giunzione allenta, accade solitamente 15 - 20 anni dopo che l'ambulatorio ha avuto luogo, cui a punto un ambulatorio della revisione può essere richiesto.


L'usura dell'articolazione dell'anca artificiale è un'altra complicazione comune di questa procedura. L'uso della protesi può indurre la giunzione a diventare liberamente, richiedendo ulteriore ambulatorio se il problema è severo. le protesi del Metallo-su-metallo sono pensate per diventare conforme ad usura più presto di quanto preveduto ed il controllo annuale di questi innesti è raccomandato.

Irrigidimento unito

I tessuti molli che circondano un innesto possono stare bene allo stiff e piombo a mobilità diminuita, sebbene questo non causi solitamente il dolore. Il problema può essere impedito facendo uso di radiotherpay o del farmaco.

Sensibilità al metallo

Qualche gente può essere sensibile o allergica al metallo negli innesti, inducenti l'infiammazione locale a svilupparsi o la guarigione in ritardo, per esempio. L'ambulatorio può anche venire a mancare complessivamente.

Sintomi severi

Un po'più di tipi rari ma seri di complicazioni che possono accadere dopo che una procedura della sostituzione del cinorrodo include:

La formazione di coaguli di sangue

Durante le settimane primissime dopo chirurgia, c'è un piccolo rischio di sviluppo di trombosi. I due posti che principali un coagulo di sangue può formarsi comprendono il cosciotto (trombosi venosa profonda), o il polmone, nel qual caso, il grumo si riferisce a come embolia polmonare. Nei casi in cui l'uno o l'altro è sospettato, il primo soccorso immediato dovrebbe essere cercato. Il rischio di formazione del coagulo di sangue può essere diminuito usando le terapie dell'anticoagulante quale warfarin.


I pazienti delle sostituzioni del cinorrodo sono ad un piccolo rischio di infezione batterica che accade all'articolazione dell'anca artificiale. I pazienti dovrebbero cercare urgentemente il primo soccorso se sviluppano i sintomi quali febbre, freddi, dolore o infiammazione persistente del cinorrodo/scarico al sito della chirurgia.

  1. Linda Tipton Linda Tipton United States says:

    My mother had her first hip implant shortly after my father passed away. After which she developed a very small tremor, barely noticable, but is now to the point after 20 some yrs. of being very debilitating. She cannot Write or even feed herself . She has dealt with repreated and ongoing infections of the bacterial type for many years & cannot seem to fully get rid of them. She is currently in a nursing home & requires 24/7 care. She has had eight children & a hard life & we think she may have some kind of a metallosis reaction to her first hip implant as she has always been allergic to cheap jewelry. She is 80 yrs. old now & we just see her slippimg away more every day & doctors say she is too old to have any surgeries for anything. So what to do,when you think that removal of the old hip replacement could significantly improve her life? I am requesting a metal test for high levels of cobalt & chromium in the blood to see what that shows since I have just read this article on it here. THANKS! Wish us luck! Linda M. Tipton on behalf of mom Della M. Bevins  Defiance,Oh 43512 at TWIN RIVERS Nursing Home.

    Knee replacement, or knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve the pain and disability of osteoarthritis. It may be performed for knee diseases such as rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long standing osteoarthritis, the surgery may be more complicated and carry higher risk.

  3. Geoffrey Hughes Geoffrey Hughes Belgium says:

    I  have had BOTH hips replaced. One 12 months ago and the other six months ago . Twelve month hip is 85% ok. The other hip the knee has become stiff. Can not find information for people who have had BOTH hips replaced.. Thank you Geoff Hughes.

    • Karen Lupinetti Karen Lupinetti United States says:

      I've had both hips replaced; the right one in 2012, and the left one a year later. The surgeries were fine, I had a super easy recovery and was back to work in 6 weeks after each one. I honestly believe that my positive attitude about needing to have them done, as well as a fantastic surgeon were the keys to my success.

      Two days ago, the right hip dislocated,  which put me in excruciating pain until it accidentally went back into place by itself. I'm being careful the last two days, and am planning to see the ortho surgeon soon to see if anything may be wrong. The X rays showed no damage, but I'm just being proactive. The ER doc Friday said Zumba may be out for a while, but not to cancel my gym membership yet!

      I'm in my early 60s, and this isn't going to slow me down or stop me from teaching part-time.

      See what's going on...and hang in there!

  4. Cathy Simmons Thorn Cathy Simmons Thorn United States says:

    I am having a very strange symptoms.  Eleven months after having a hip replacement, I am having a faint redness (circular) on the incision with bruising that has followed the incision line starting at the bottom of the incision toward the foot and moving up the incision line to the top.  This is very puzzling.  Anyone else out there ever had this situation?

  5. Barbara Rodriguez Barbara Rodriguez United States says:

    Was curious... has anyone else feel like where the bone in your leg meets the metal from your new hip does it feel like its going to snap?does anyone else have extreme amounts of pain after your total hip replacement and lots of problems? I want to know if this is normal ?

  6. Veronica Ralston Veronica Ralston United States says:

    i had hip replacement last May 2015 after i went home after 2weeks, my hip popped out of joint. This kept happing  every 2-3 weeks my doctor said i have loose joints. I had never heard of this.  He finally went and put a collar on the hip.  It has not popped out of joint any more but it makes a lot of noise.  Have you ever heard of this or is he trying to cover up for something he done wrong.

  7. Robin Smith Robin Smith United States says:

    In July 2013 I had left hip replacement.  Over the last 2-3 weeks I am experiencing pain very similar to what I had before the hip was replaced.  The hip is especially painful at night again. I have no difficulty walking or standing from seated position.  "Sometimes" I feel like the hip is going to give out climbing stairs.  I had absolutely no complications after surgery.  My right hip was replaced last Sept. 2015 with no complications immediately after surgery or to this day  I have a one year check up appointment with my surgeon in a couple weeks.  I definitely plan on discussing the left hip pain with him at that appointment.  In the meantime, what could be causing the pain?

    • Ellen Wise Ellen Wise United Kingdom says:

      Yes, me too.  Hip operation about same time as you Robin.  No complications, BUT from day one, it never felt right.  I think the 'wrong' mattress in hospital does not help, but there are not enough of the right ones to go round.  Also, the folk who shout the loudest get them!  Cannot sit comfortably for longer than 15 minutes and travel in a car is excruciating.  I can walk, but when I rise I have to hold the front of the hip and groin to get up at all!  Not happy one bit.  Surgeon?  Nice man, shame about the attitude - "I don't make mistakes" - really?......

  8. Linda Jones Friedel Linda Jones Friedel United States says:

    I fell in 2012 and broke (shattered) my right hip. Went to the ER, had to lay there for 13 hours before a surgeon finally came.  He did the surgery, not a total hip replacement. That only lasted a couple of months before it became unattached.  I went back for a total hip replacement, and have had pain ever since, also I loose my balance a lot. I can walk for about a half hour, then the pain starts.
    I've always slept on my right side, but when I do this, I wake up in extreme pain.  I've gone to see other doctors, but they say it's just fine!!!  No one wants to clean up someone else's mess, it seems.
    The pain goes down to my foot.   I also have Osteoporosis.
    My scar is 13 inches long, and the muscle never grew back, like the doctor said it would.
    Is there any hope for me????   I want my life back.

  9. Norma Johnson Norma Johnson United Kingdom says:

    I had my left hip replaced 2 years ago and my right one this January. Since having the 2nd one done I am not confident walking about as I feel I am unbalanced but my consultant says I am fine as the hips are both the same. Today when I was out I suddenly felt the right hip clicking as I walked and although I have no pain I feel somethings wrong. It sounds like a ratchet being wound up when I walk.Has anyone had this happen and could it be a warning f the hip dislocating? Any info would be welcome as I cant find anything online about it.

  10. Bettye Short Bettye Short United States says:

    I am wondering how often this happens.

  11. Don Yvonne Ryder Don Yvonne Ryder Canada says:

    i had my left hip replaced for the third time three years ago which left my leg numb from the knee down .i was told it would get better but it isn,t . so i have to walk with a walker. I was wondering if anyone else has this problem

  12. Alecia Papineau Parker Alecia Papineau Parker United States says:

    I had both hips replaced in 2014. I'm still having problems standing and sitting. While sitting I feel like I'm sitting on golf ball's. Is anyone else having or had this problem?

    • Kathy Radford-Scarale Kathy Radford-Scarale United States says:

      Hi had left replaced and never been quite right. Feels like I am sitting on something and when I stand up I usually have to stand still and get juices flowing before I can take a step. Sometimes have to hold onto things and then after a few steps gets a little better. Doc still can't figure what is wrong and is now talking about revision surgery....

  13. Melanie K Kelley Melanie K Kelley United States says:

    I had a total hip replacement and have had a lot of pain that started about a year ago and have not had any luck with getting the doctor to even look at it.  Get really sharp pain in pelvis when I sneeze cough or just move to fast.  Climbing stairs or hills also causes a lot of pain, and have numbness in lower leg.  Does anyone else have those problems.

    • Preston Ricks Preston Ricks United States says:

      I'm still having pain after walking 20 min or so and the numbness in my thigh is still very present. I see I'm not the only one going through this and somehow I feel better sorry! But this has been worrying me for sometime now and not trying to be a baby about it or that's how the surgeon makes me feel. Sorry your going through this but in short you are not alone. A bone density scan is the next procedure they want to run now to narrow down why I'm having so much trouble

  14. Michael Kennedy Michael Kennedy United States says:

    I had a total hip replacement on my right side in May of 2014.  Starting in August of 2014 I have had pain or spasms in my right thigh. I have talked to my hip Surgeon and no luck there and have even been to a spin surgeon to see if this could be related to the bad disks in my spin. He ran tests and nothing showed.  This pain does not show up all of the time, but when it does it stops me dead in my tracks.  Anyone else experiencing this type of thigh pain?

  15. Keith Herbert Keith Herbert United Kingdom says:

    I have a titanium hip replacement done in may 2017 I am getting irritation in my stomach area and throat. My emissions are affected. I experience a different a smell. I get what I call the titanium aroma emitting from my body. Does any one know what is the best treatment. please.

  16. Cate Muegge Cate Muegge United States says:

    My 92 year old mother had hip surgery and after 3 days in hospital she went to a rehab center where they continued to get her out of bed and sit her up, and try and make her stand up.  Is that right to do?  Also they did not cover the procedure where they stapled her back together.  Within a week she was back in the hospital with a severe infection and another surgery.  Her incision was not covered the whole time she was in the rehab.  Shouldnt it have been covered with bandages and medication to prevent infection?  What did they do to you when they closed the incision and sent you packing out of the hospital?

  17. Robert Gann Robert Gann United States says:

    I had my right hip replaced last may 2017, I have been walking since the day of the replacement. I went through what the doctor called three weeks of hell. You all remember that. They went through the front of my leg. I healed up pretty good no oozing or anything. The hip has never quit hurting. My surgeon quit two weeks after my surgery so I had to do my check ups with another doctor in the same office. I tried to tell him that I couldn't sleep and that the hip was still killing me. I had just quit taking the prescribed pain pills. I just wanted to let him know what was going on and what can I do to try to sleep at night. I lived in a rural area that was a hundred mile round trip. My surgeon told me that due to where I lived it would be difficult to do physical therapy so my wife became my therapist. We had everything we needed from the therapist for exercising and complied religiously. Anyhow went to see this other doctor and he went off on us and told us that he didn't want to hear anything from us and that's why my doctor wasn't here anymore. Then got into my wifes face and told her that he wasn't going to loose his license due to pain pills which we were not even asking for. That was last June we have since moved to the Oregon coast. I walked on the beach a lot until my hip seemed to get worse clicking in the hip my groin pain getting worse and my femur hurts like walking on a broken leg all of which never went away. I have a new primary care doctor here and I have to go every three months to have my A1C checked because I'm also a diabetic type 2. Needless to say I haven't worked since March 14th 2017 due to this hip. I have been telling my new doctor what is going on. She decided to do a white blood cell count in my new labs. The labs came back and I have an elevated white blood cell count. She say's due to my pain in my new hip and elevated white blood cells that I have now got an infection in my new hip. I'm wondering if this has been there since the replacement. Now I don't walk on the beach it hurts too much now. Cant sit for long and cant walk or stand for too long my groin is still killing me and to add to all of this I have bad head aches sick to my stomach and the chills. Now I have to go to corvalis Oregon now to get fluid pulled out of this new hip (more pain) meanwhile I'm not on anything for pain not even asprin just toughing it out. Waiting to see these people and will keep you folks updated.

  18. Paula West Paula West United States says:

    I have an abscessed tooth that is still hurting despite an extended antibiotic treatment with amoxicillan...about 2 weeks. I am waiting for the insurance company to let me know if a tooth implant will have any insurance coverage and if the extraction would at least be covered. I went onto amoxicillin as soon as the tooth started to hurt. It took a few days before my dentist could see me.  It's not getting a lot better.  I still have tooth pain in the tooth.  My dentists thinks the tooth might be cracked. Now I have developed a stabbing pain in the area of my left front leg where the groin and the leg/hip come together.  This is an artificial joint.  I had it done 4 years ago and have never had any issues with it. It is a stabbing pain right where the pulse in that area is located.  It comes and goes without any rhyme or reason.  I am afraid the infection may have spread to my artificial hip joint.  But the pain is definitely in the groin area.  Any ideas?

  19. anita slater anita slater United States says:

    Had Total left hip replacement 5 months ago. Dislocated it 2 times within first 2 weeks, Have had severe pain in lower neck,,& shoulder on opposite side. But pain radiates down to lower back into middle of buttocks into groin area down middle of thigh then toward outer side of left hip where surgery was done. I’m Limping now & pain is awful sitting, standing,or walking. Hip has been x-rayed showing healing is fine but this pain persists. I also fell once during this time. I’ve had sciatica problems in the past & had nerve endings (burned) which helped for a year or so then procedure was repeated 2 more times over several years. I have degenerative disk disease with both knees replaced. Do I need a cat scan done or go back to pain management dr. to see what he thinks is wrong? I’ve hurt for months now with no relief. I’ve tried heat, cold, all kinds of ointments & pain just persists. Please help as Hospiceishelping mew/my terminal ill husband who has cancer. I’ve just got to find out what’s wrong & FIX IT!
