Playing tennis after a total hip replacement

September 3rd — admin

My husband had a total hip replacement about six months ago. He’s back to running and playing tennis as if nothing ever happened. Is there any danger of being too active after  a joint replacement?

There isn’t a simple yes/no answer to this question. Many doctors caution their patients to avoid high-impact activities such as running and tennis. There’s some concern that the implant won’t last more than 10 to 15 years. That could mean another surgery on the same hip.

On the other hand, it’s clear that weight-bearing activities are important to maintain good bone strength and density. Studies show that patients who are less active and more sedentary actually lose bone. Bone loss around the implant can cause it to loosen and require revision surgery.

Your husband’s surgeon is probably the best one to ask this question. Knowing the type of implant and surgical procedure used can make a difference, too. When patients are educated and informed about their joint replacements, then they can make the best decisions about activity and lifestyle.

For active, healthy adults, being more active than is advised may improve their quality of life enough to make it worth the risk.

Partial hip replacement may result in fracture

August 26th — admin

My mother just had a partial hip replacement. I guess it was like having a tooth capped. Just the top of his femur was replaced. She ended up with a hip fracture afterward. Is this common?

It sounds like your mother had an operation called joint resurfacing. This type of operation has been around since the 1930s. It has come and gone based on problems afterward and materials available. Most recently, new metals have made it possible to resurface the head of the femur (thigh bone) with good results.

Fracture (usually of the femoral neck) is the most likely complication of hip joint resurfacing. It happens in up to four per cent of the cases. Studies show fracture occurs most often in the first 100 cases done by a surgeon. Fracture rates go down as the surgeon becomes more familiar with this technique.

Causes of fracture are both patient and technique-related. Obesity, decreased bone mass, and arthritis make a difference on the patient side. Anyone with a femoral neck cyst should get a total hip replacement instead of resurfacing. Putting the implant in with too much of a tilt or twist can also result in fracture.

Women seem to have a higher risk of fracture after hip joint resurfacing. The reason for this remains unknown at this time. Short-term results of hip joint resurfacing are good to excellent. Long-term studies aren’t available yet. Total hip replacement may be needed by patient who have a fracture after resurfacing.

Is a total hip replacement necessary for just one part?

August 23rd — admin

I just got the results of my hip X-rays. One hip has arthritis but just at the top of the thigh bone. The round ball in the socket is all broken down. It’s not really round anymore. Do I have to have a whole hip replacement just for one part?

Maybe not! You may have a couple choices. The first is called a hemiarthroplasty. The surgeon removes the round top of the femur (thighbone) and drills out some of the bone down inside the shaft. Then a replacement top and stem are inserted down into the bone.

Or if you are younger than 60 and have good bone stock, you may be able to have a hip resurfacing arthroplasty (HRA). In this operation, just the top or cap of the femoral head is removed and replaced. It’s a lot like having a tooth capped by the dentist.

Your surgeon will be able to tell you both what is possible and what he or she can do. Not all surgeons perform all types of joint implants. Experience is important so it’s a good idea to go with what your surgeon is skilled at doing. If you are a good candidate for a HRA, then you may want to go to a center where this operation is done routinely.

What’s the age of the average patient who gets a hip replacement?

August 13th — admin

What’s the age of the average patient who gets a hip replacement?

It used to be the average age of a total hip recipient was mid-60s or older. Because the typical implant lasts around 15 to 20 years, surgeons waited until patients were older before giving them a total hip replacement (THR).

That policy is slowly changing based on several factors. First is demand. As adults remain active longer, the need for joint replacement earlier is increasing. Second, the materials and methods used with THR have improved dramatically over the last two decades. Better and better long-term results are being reported. The age and type of patients eligible for THR is expanding every year.

According to a large 25-year prospective (looking back) study, the average age of patients getting their first THR has been around 69 years old. The age range was from 24 to 88 and older. If there are no complications, today’s THRs can last 25 years or more.

Some patients report pain, stiffness, and loss of physical function as time goes by. Most aging adults slow down their activity level anyway so the decline in function doesn’t impair their life style. Researchers hope that with improved implants, better long-term results will make it possible to stay active longer.

More hip replacements means more hip fractures

August 5th — admin

I’ve been a nurse on the med-surg floor for over 20 years. I think we are seeing more and more hip fractures in patients with a hip replacement. What’s causing this increase in numbers?

Several studies have confirmed your observations: the number of femoral (thigh bone) fractures after total hip replacement (THR) is on the rise. There may be several reasons for this change.

First of all, more people are having THRs. Good results from the surgery has also increased the number of people and types of problems that can be helped by THR.

Third, with more people having THRs, the number of revision operations is increasing, too. Patients who have had a THR 20 years ago are still alive and going strong. Increased physical activity decreases the life of the implant. Many of these patients have revision surgery to replace the first implant. Fractures are more likely and more common after revision surgery.

Finally, implant design may be a factor. A recent study from Sweden pointed out the fact that implants with a straight and short stem are more likely to loosen causing dislocation and/or fracture. Complications such as fracture and implant loosening may be further reduced with continued research and improved implant design features.

How common is revision hip replacement surgery?

August 2nd — admin

Both my parents have had total hip replacements. Both have had to have a second operation on the same hip. Is this a common thing or just a coincidence?

Reoperations after total hip replacement (THR) are not uncommon. The most common reasons for reoperation are loosening of the implant, repeated dislocation, or bone fracture around the implant.

Most patients report minor trauma before bone fracture. Spontaneous fracture (no known cause) is more likely after revision surgery. Revisions are done to repair or replace the primary (first) THR.

Other reasons for reoperation can include nonunion of the fracture or refracture. Sometimes infection or fracture of the implant can occur.

Researchers are collecting data to help sort out who is at risk for implant failure or reoperation. One way to do this is to create a national patient registry. For example in Sweden, anytime someone has a total hip replacement, the surgeon must report information about the case to the Swedish National Hip Arthroplasty Register.

This registry has three separate databases. Each one collects slightly different bits of information. This allows researchers to group data together for easier analysis. Information can be used to identify who has a reoperation, fracture or refracture, or other complications.

Patient selection, implant choice, and experience of the surgeon all seem to be important factors in THR surgery. Your parents’ situation could be the result of one of these factors — or it could indeed be just a coincidence. We still don’t always know how to tell exactly what caused the problem in order to prevent it.

Could soccer playing wear out my hip?

June 23rd — admin

I’m 45-years old and need a hip replacement because of arthritis. I played soccer from the time I was in pre-school all the way through college. Even as an adult I played on coed rec teams. Could the soccer playing wear my hip out?

Playing soccer may not be the issue. Studies show it’s the sports injuries players get that increase the risk of osteoarthritis. Ankle and knee injuries are common among soccer players. Since these two joints are in a direct line-up with the hip, it makes sense that such injuries can lead to arthritis later.

Another risk factor for injury and thus arthritis is left-leg dominance. At this point we know more about what isn’t a risk than what is. In studies of soccer players ages 12 to 18, there was no apparent increase in risk of injury linked with body size or type, balance, strength, or flexibility. Preseason play didn’t seem to make a difference either.

MRA more accurate than MRI for ddetermining cause of hip pain

June 18th — admin

What is magnetic resonance arthrography (MRA)? I’ve heard of MRI but not MRA. My doctor wants me to have an MRA to help figure out what’s wrong with my hip.

Magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) are very similar tools. MRA is basically MRI for the joints. It is more accurate in detecting joint problems. MRI can confirm there’s a problem in the joint. MRA shows exactly what is the abnormality.

CT scans work well for bone lesions around the hip. CT scan shows places where the bone might have a tumor, abnormal anatomy, or necrosis (dead cells).

If you ever need surgery on the hip, advanced imaging studies of this type are very important. The more details the surgeon can see ahead of time, the better the surgical plan with no (or very few) last minute surprises.

Double hip replacement an option?

June 7th — admin

I have pretty bad hip arthritis. The doctor is going to do a hip replacement on the worst side first. The other side isn’t really too good. How will I manage with one bum hip and the other one just operated on?

You may want to ask your doctor about having both hips done at the same time. If you are in good health and qualify, this may be the best option for you. Without the stiffness and pain on the nonoperative side after a single replacement, you can move along faster in rehab, too!

There’s also a cost savings. Even though you’ll be in the hospital longer than if only one hip was done at a time, the overall number of days is less when both hips are done together.

You can have bilateral hip replacements in one of three ways. First, they can both be done in the same surgery. Second, you could do one and finish rehab before having the second one done. There’s usually at least six to eight weeks between operations. Some people wait longer. Third, you could have one hip done and wait five to seven days. If your health is stable and you’re up for it then have the second one done. With this third method, you don’t leave the hospital between operations.

If you still opt for one hip replacement at a time, then a physical therapist will help you. Your home may need to be adapted to make toileting, bathing, sleeping, and household chores easier. You will likely need a family member or live-in assistant for a few days to weeks, depending on the speed of your recovery.

Mini-incision hip replacement can mean shorter hospital stay

June 2nd — admin

I heard the new mini-surgery for hip replacement takes less time and fewer days in the hospital. How much less?

The answer to your questions really depends on the surgeon. If the mini-incision method is fairly new to the surgeon, the operation itself can take longer. If all things are equal (the doctor has done the same number of both operations: open and mini), then the time is about the same.

Length of hospital stay also varies. The hope is that the newer mini-incision method will mean a shorter hospital stay. But hospitalization may be longer if there are any complications during or after the operation. For example, fractures and dislocations may happen more often when a surgeon is learning a new technique.

A recent study from the University of Missouri reports on this. An experienced surgeon had an overall rate of 42 percent for problems after a two-incision mini-invasive hip replacement. That was compared with six percent for the single-incision method. The surgeon also reported a 25 percent rate of nerve injuries. Any of these (or other) problems can extend a patient’s stay in the hospital.
