ALL ABOUT SQUEAKING NOISES.
(seeing and hearing...? Click here)
Also called peeping, called by Dr.De Smet the “peepcreep”. The squeaking noises are produced due to a temporary lack of lubrication, a dry running of the metal-on-metal prosthesis. . It sounds as a non-lubricated creaking hinge of a door. The duration of the noise is normally less then 24 hours, and a one-time incidence.
It starts when the patient has an increase or change in activities. Stair climbing always generates or increases the noise. (Possible provoking activities: mountain climbing, mountain walking, chopping wood,…)
It does not occur any more 2 years after surgery. Two year is the time interval that equals the running in period of a metal-on-metal friction couple. Running in means that the prosthesis is polishing itself. Immediately after surgery, the lubricant (lubrication film) between the 2 components of the prosthesis is blood. This will change to serum with our own proteins after a while. The percentage of patients where squeaking noises appear is about 1.5%.
It is a benign incident that goes away spontaneously and do not need any panic. (let it know to your surgeon for statistical reasons!).
The clunking noises and clicking feeling in the first 6 months after surgery is a temporary decoaptation of both components. This means that the two big metal parts of the prosthesis come apart and come together again. Having a large diameter this gives no wear of the prosthesis and will not destroy anything. Because of the release of the capsule around the hip to be able to do a resurfacing procedure without sawing the head of, the hip joint is looser at the beginning. This is even more because of the badly trained muscles of the preoperative condition and all the fluid around the newly placed joint.
The clunking is painless and subsides once the capsule and muscles around the hip are fully healed. It occurs in the first 6 months after surgery and disappears progressively.
The incidence can be around 20% of all patients!
This finding should not be confused with local conflict problems with prosthesis or bone because of less ideal inserted implants. These will stay even after 6 months, will not become better, is painful and should be diagnosed by your physician.
For example if I have a complication after a month or an infection during the operation or I’ll have continuous pain. What will you do in such cases, what is your responsibility and liability?
In complications, problems known to happen in hip surgery there is nothing to be called liability. For a patient the surgeon has always the responsibility to help him as much as he can, this with answering questions, giving advice and if you are at the hospital, or you come back to the hospital give you a treatment. For all complications needing more treatment and including a higher cost, patient has to pay for this.
