Hip Replacement

1) To make it easy for the patient to understand the use, warnings, and directions.

2) OTC medication might have significant drug interactions with the prescription drugs the patient may be taking so the warnings should be clearly stated.

3) To make it less likely that the patient will need to seek counseling from the pharmacist.

There's a tv commercial that says to get a lawyer they have millions set aside for you!

A hip replacement consist of a cup, and a stem (that sits in the femur). Typically a surgeon will either press fit a hip replacement in (fit in tight, and allow the bone to grow into it), or use a bone cement to secure the implant in position.

A hybrid typically means he will cement one component in, and press fit the other.

You should limit yourself to swimming or stationery bikes at least at first if you need the exercise.

The surgeon will need surgical blades, saws, drills, rasps, reamers (like a file, and a cheese grater), as he has to cut away the bad pieces of bone, which are pretty hard (you've seen a butchers shop right!?).

I had a very large amount of swelling in my legs, ankles and feet after hip surgery. It became worse after walking. A regime of pumping my feet up and down (point toes out, then flex) as many times a day as possible, plus elevating them for at least 20 minutes after walking helped enormously.

If she 'just' had surgery, it is because they have just cut through her skin, muscle fat, and cut the bone and probably used a large metal mallet a lot. Nothing unusual, should subside with time.

Sure, at the most you might need some minor modifications to the pedals.

I had hip replacement surgery 2 years 2 1/2 months ago and my upper thigh is still numb! I was told it could be up to three years until I get the numbness to go away! I have until 2013 to look forward to finding out.

I think you can but it has to be a serious accident to break the implant from the bone. I think usually people refer to breaking a hip as an explanation for dislocation which happens more commonly and with less force needed

When i get hold of u all

I had a total hip replacement when I was 28 and it was the best decision I ever made. I am totally pain free and more active now than ever. That was almost six years ago. BEST ortho doctor is Dr. Hozack from the Rothman Hozack Institute, they operate out of Thomas Jefferson - Philadelphia

For young patients with good quality bone stock but are effected by osteoarthritis then there is no better solution than the Birmingham Hip Resurfacing (BHR).

A BHR is a bone conserving alternative to a Total Hip Replacement (THR) is hip resurfacing. The BHR is an implant aimed at young active patients who want there quality of life back!

Patients who have had BHRs have gone on to run marathons, climb mountains and much more due to the success of their implants.

Instead of replacing the old worn out joint, a BHR resurfaces the femoral head with a Cobalt-Chrome component and inserts a Cobalt-Chrome cup into the acetabular socket. This metal on metal technique last longer and has less wear than the traditional Metal on Plastic THR.

By conserving the bone at the femoral head, revisions should they be needed are much simplier than they are if a THR has been carried out at first.

The BHR was pioneered by Derek McMinn in Birmingham, UK. The implant has a high success rate currently at 97% at 13 years which compared to similar statistics for a THR, they are staggering.

Derek McMinn has received accollade from the world over and has lectured to some of the biggest names in Orthapaedics. Mr McMinn is known internationally for his work and continues to operate on patients from all corners of the globe.

This should not limit you much, though I would avoid career that involve a lot of bending over.

Normally, the hip replacement will 'deteriorate' due to wear, as the particles can lead to a body reaction leading to osteolytic loosening. Though some patients don't get this.

This is a question you should best ask your DOCTOR. It could be something she would really need to know.

The old view was always to leave the operation as long as possible but thinking has now changed. A painful, arthritic hip will continue to deteriorate whilst waiting for surgery with the possibility that the operation will become more difficult. In addition the other hip is likely to be affected as it will be doing most of the work.

Quality of life is now the best indicator. How much is your hip condition affecting your ability to work and play. Can you still take a stroll in the park, eat out in a restaurant or sit through a movie? Can you still pick up your children when they need a hug? How far are your daily activities hindered because of your hip?

The current thinking is that the best time to have a hip replacement is when the loss of quality of life outweighs the pain you are experiencing.

Only if you are sitting on the hob!

Hip replacements are made of different parts.

The stem (portion that goes into the thigh bone)

The head and cup (the bearing surface)

The socket (portion that holds the cup into the pelvis).

The stem is always metal. Usually a cobalt chrome alloy. This may either be coated with titanium or a cermaic such as hydroxyapatite (rough surface) which allows bone to grow onto the stem and hold it fixed in place. Or the stem can be highly polished and cemented in place with polymethylmethacrylate cement.

The socket can either be all polyethylene (usually UHMWPE) and cemented into the pelvis directly (i.e. the cup and socket are one), or the socket can be metal and bond to the pelvis in the same way as the rough stems, with or without the use of screws.

The bearing surface (ball and cup) can vary -

The ball can either be metal or ceramic (alumina), and the socket can either be metal, ceramic or polyethylene (UHMWPE). The polyethylene cups can either be an all in one cup/socket, or a polyethylene liner to a metal socket.

The bearing combinations typically used are:

Metal on polyethylene

Metal on Metal

Ceramic on Ceramic

Ceramic on polyethylene

All have their pros and cons.

There are quite a few variables here

1. There are two versions of each. Metal on metal and metal on polyethylene and ceramic on ceramic and ceramic on polyethylene

2. Polyethylene wears out quicker then either metal or ceramic

3. There is currently a massive recall of metal on metal hip implants. These tend to shed minute particles which can cause rejection of the implant and can enter the bloodsream. The plus side for metal on metal is that they can use larger cups (pelvis side of the joint) which means they are less likely to dislocate. Though rate of dislocation will depend on other factors as well e.g. surgical approach used.

4. Ceramic has a long life span but in a few cases makes a horrible squeaking noise and in even rarer cases they can shatter - known as catastrophic failure! Like metal on metal they can use a larger cup size.

Ceramic and ceramic is probably now the current favourite

If I had to chose I'd definitely go for ceramic on ceramic.

Whether they have a new hip or not, you are putting a magnetic strip into an incredibly strong magnetic field. The MRI should be enough to wipe or corrupt the data in the strip.
