My family has a history of hip problems. Is there value in having my hips X-rayed to see if they are okay?

February 3rd — admin

My family seems to have a history of hip problems. We don’t all have the same condition but quite a few have arthritis. Is there any value in going in and having X-rays taken to see if my hips are okay? I don’t have any pain but I’m getting up there in age.

Research shows that about eight per cent of the general population develops arthritis. This is probably an under estimate as it is based on X-rays and many people don’t have routine X-rays that reveal this diagnosis. In an effort to prevent arthritis, there are some experts who suggest routine screening for problems that might result in arthritis. But the cost of performing X-rays and/or MRIs on everyone may not be cost-effective.One condition that can lead to early degenerative changes is called femoroacetabular impingement (FAI). Perhaps one or more of your family members has had this diagnosed as the predisposing factor for their arthritis.Impingement refers to some portion of the soft tissue around the hip socket getting pinched or compressed. Femoroacetabular tells us the impingement is occurring where the femur (thigh bone) meets the acetabulum (hip socket). There are several different types of impingement. They differ slightly depending on what gets pinched and where the impingement occurs.A recent study was done to see how many people in the general population have this problem. They took MRIs of the hips of 200 adult volunteers (ages 21 to 50) for a total of 400 hips. By examining the MRIs against other tests performed, they were able to see that 14 per cent of the people had femoroacetabular impingement and didn’t know it.In this study, they specifically looked at age, gender (male versus female), body-mass index (a measure of obesity), and ethnicity. These potential factors may put people at increased risk for impingement and then for going on to develop arthritis later.There were some significant findings from the measurements taken of each volunteer when compared with their MRI results. The elevated angle measured on X-ray (called the alpha angle) wasn’t diagnostic of femoroacetabular impingement by itself. (Though it was a predictor of hip pain and joint cartilage damage). When combined with restricted hip internal rotation, the alpha angle could be used to predict impingement. A positive impingement sign was a reliable indicator of a problem with the labrum (rim of cartilage around the hip socket).What this tells us is that your orthopedic physician can examine you and offer some direction as to whether or not an X-ray or MRI is even needed. If you are painfree and there are no clinical signs of impingement or arthritis, then it may be appropriate to just monitor your situation. This will avoid unnecessary costs and exposure to X-rays while still keeping an eye out for any signs of developing problems.

If you have femoroacetabular impingement, is it inevitable that arthritis will eventually set into that hip?

February 1st — admin

Is it always the case that if you have femoroacetabular impingement (which I have) that arthritis will eventually set into that hip?

Not necessarily though many individuals with femoroacetabular impingement (FAI) do indeed eventually develop degenerative changes that lead to arthritis. This is most likely to happen in cases of untreated FAI.Let’s define femoroacetabular impingement and talk about how it can lead to osteoarthritis of the hip joint. Impingement refers to some portion of the soft tissue around the hip socket getting pinched or compressed. Femoroacetabular tells us the impingement is occurring where the femur (thigh bone) meets the acetabulum (hip socket). There are several different types of impingement. They differ slightly depending on what gets pinched and where the impingement occurs.The cam-type of impingement is the most likely to set up conditions ripe for joint wear and tear. This type occurs when the round head of the femur isn’t as round as it should be. It’s more of a pistol grip shape. It’s even referred to as a tilt or pistol grip deformity. The femoral head isn’t round enough on one side (and it’s too round on the other side) to move properly inside the socket.The result is a shearing force on the labrum and the articular cartilage, which is located next to the labrum. The labrum is a dense ring of fibrocartilage firmly attached around the acetabulum (socket). It provides depth and stability to the hip socket. The articular cartilage is the protective covering over the hip joint surface. This abnormal contact between the femur and acetabulum is the leading cause of labral tears and degenerative hip arthritis.Treatment is advised when impingement is painful, limits function, and/or X-rays show potential for joint changes. You may be able to follow a conservative path by modifying activities and carrying out a program of strengthening and stretching exercises. In some cases, surgery is indicated to correct the problem.No one knows for sure who will develop arthritis. Studies are underway to determine how common is the problem and what factors might increase the likelihood of developing arthritis. Your orthopedic surgeon will follow your case and advise you if and when treatment (and what treatment) is appropriate.

Does femoroacetabular impingement (FAI) surgery work? What are my chances for a successful FAI operation?

January 30th — admin

My question for you today is: does surgical treatment for femoroacetabular impingement (FAI) work? I’m facing the decision whether or not to have this surgery, and I want to know what my chances are for a successful operation.

We may find some helpful information to answer this question from a recent systematic review of studies done regarding surgery for femoroacetabular impingement (FAI). The statistical significance of any conclusions from a systematic review is worth noting. That’s because such a review combines the results of many smaller studies to give an overall view of the results of treatment like surgery for FAI of the hip.Impingement refers to some portion of the soft tissue around the hip socket getting pinched or compressed. Femoroacetabular tells us the impingement is occurring where the femur (thigh bone) meets the acetabulum (hip socket). There are several different types of impingement. They differ slightly depending on what gets pinched and where the impingement occurs.Most studies on this condition are case studies. That’s because no one surgeon sees 100s or 1000s of patients with this problem. Case studies are good because surgeons have to start somewhere when trying to see the effects of treatment. The problem with published case studies is that this is considered a low level of evidence. A surgeon wouldn’t want to treat any patient with methods considered “successful” based on low levels of evidence. Conducting a systematic review like this one allowed the authors to examine the data on 970 different patients (collected from 23 reports of case studies). Now surgeons can see what the latest findings are and evaluate their own practices based on what is statistically significant.One of the questions specifically addressed in this review is the very same one you raise. Does surgical treatment for femoroacetabular impingement (FAI) work? The answer to this question may depend on how “success” is defined.If pain relief is the measured outcome, we know that the majority of the 970 patients included did have relief of painful symptoms. A second outcome was improved function. That was also a benefit of surgical repair for femoroacetabular impingement (FAI). Levels of patient satisfaction as an outcome measure were not so high. For those patients whose pain didn’t improve and especially those patients who ended up having a hip replacement, reported patient satisfaction was low. In some studies, the rate of dissatisfaction and/or conversion to hip replacement was as high as 30 per cent.The obvious next question is: can we predict who will have a poor result? That’s a simple question that doesn’t have a simple answer yet. One risk factor for worse outcomes with femoroacetabular impingement surgery is advanced joint arthritis at the time of the diagnosis. But there are two problems with relying solely on this factor.First, not everyone with severe damage has a poor outcome with surgery. Just as many patients with severe damage had good outcomes as those who had a failed treatment. The reasons for those differences remain unknown and will require further study. Second, even with X-rays and MRIs, it isn’t always possible for the surgeon to know the full extent of the damage. Sometimes, it isn’t until getting inside the joint that the surgeon can see what’s really going on. These tests are still important and the results should be discussed with you by your surgeon when making the final decision about the best treatment choice for you.

If I have one bad hip from osteonecrosis, does it necessarily follow that the other hip will go bad too?

January 26th — admin

If I have one bad hip from osteonecrosis, does it necessarily follow that the other hip will go bad too?

Osteonecrosis means “bone death”. Loss of blood supply, bone death, and collapse can occur over a period of months to years. The femoral head is the round ball at the top of the thighbone that fits into the hip socket. Osteonecrosis can be caused by steroid use, alcohol, trauma, and blood-clotting problems like Sickle Cell Disease. In some cases, no cause can be found. Many people who have been diagnosed with osteonecrosis of the femoral head already have the same problem in the other hip. They just don’t know it because the disease can be “silent” or asymptomatic. In other words, there’s no pain. If it wasn’t for the telltale signs on X-ray, the affected individual wouldn’t even know there was a problem.The majority of people who have femoral osteonecrosis in one hip will go on to develop the same problem in the other hip. But this isn’t always the case and even if it does happen, treatment may not be needed.So how does a person decide what to do? The first goal in treating symptomatic (painful, limiting) osteonecrosis of the femoral head is to save the bone. The second goal is to keep function while relieving pain. Your surgeon will be able to advise you as to the best course of action for you. That still doesn’t answer the question about what to do for that asymptomatic hip. Is treatment needed at all? What’s the natural history (i.e., what happens over time if it is NOT treated)? In a recent systematic review of the literature, surgeons who conducted the study concluded that large lesions along the outer two-thirds of the femoral head are in the greatest danger of further destruction and collapse. Those should be treated right away. Small-to-medium lesions can be watched carefully and treated conservatively at first. Any sign of progression of disease should be addressed immediately. Anyone with known risk factors (Sickle cell disease, prolonged use of steroids, alcohol abuse) should be watched closely as well.

Early treatment of hip disorders can prevent later complications

January 18th — admin

Ever since I was a young teenager (maybe around 13 or 14), I’ve had a snapping hip problem. The general consensus at that time was to just ignore it. Now I’m in my late 30s and it is still bothering me. Should I see someone about this before another 20 years go by — or is it still considered a benign problem (don’t worry about it)?

It might depend on the cause of the problem. If you have a femoroacetabular impingement, then early osteoarthritis is possible, even probable. Just the slightest change in the morphology (shape and structure) of the hip joint can cause problems like this. Femoroacetabular impingement refers to some portion of the soft tissue around the hip socket getting pinched or compressed. Femoroacetabular tells us the impingement is occurring where the femur (thigh bone) meets the acetabulum (hip socket).

There are several different types of impingement. They differ slightly depending on what gets pinched and where the impingement occurs. The first type of femoroacetabular impingement (FAI) is called pincer impingement. This type occurs when the rim of the acetabulum (hip socket) sticks out farther than normal. There are several causes of this problem. There can be an overgrowth of cartilage forming the rim or even extra bone that forms in the area. Sometimes the hip socket is tilted backward slightly. In either case, every time the athlete flexes the hip, the rim that’s sticking out too far pinches the labrum against the neck of the femur. The labrum is a fibrous rim of cartilage around the socket to help give it some depth. It is a normal part of the hip biology.

The second type of femoroacetabular impingement is called CAM impingement. Normally, the head of the femur is a smooth, round shape. It is even all around so it can rotate inside the socket evenly. But any change in the shape can cause it to hit one point of the socket more than the others as the head of the femur moves inside the socket. The asymmetrical rotation of the pistol-shaped femoral head is called the cam effect. Anytime something repeatedly rubs against something unevenly, there is uneven wear, tear, and damage. In this case, when the hip is flexed or bent, the unevenly shaped femoral head doesn’t glide over the labrum as it should. Instead, it bumps up against the edge of the cartilage. Over time, the labrum gets worn down to the bone.

And finally, the third type of femoroacetabular impingement is a combination of the two just described (pincer and cam). Cam impingement is more common in males and brings on symptoms earlier than the pincer type. The combination of both types together causes problems sooner than if only one type was present. The best thing to do is see an orthopedic surgeon for an examination and diagnosis. It may be good to do this before any more time passes by. Early recognition and treatment of most hip disorders involving the soft tissue structures help prevent serious complications later.

I’m a Catholic priest and every time I kneel down my hip replacement squeaks. What can I do?

January 12th — admin

I am a Catholic priest with a strange problem. Every time I kneel down and get back up, my hip replacement squeaks. And it’s loud enough to be heard by every one at Mass. What can I do about this?

You are not alone though your situation is certainly unique. The problem of squeaking hips after joint replacement has increased in the last 10 years with the increased use of hard-on-hard bearings. What do we mean by hard-on-hard bearings? The two main parts of the hip that are replaced include the round head at the top of the femur (thigh bone) and the cup-shaped hip socket.The materials used for these component parts can be ceramic-on-ceramic, metal-on-metal, or metal-on-polyethylene (plastic). Metal-on-metal and ceramic-on-ceramic are the hard-on-hard bearings. Ceramic-on-polyethylene and metal-on-polyethylene are considered hard-on-soft bearings.It appears that there are three main factors involved and usually more than one reason for the squeaking. Patient factors such as body size and mass (larger), height (taller), and activity (hip flexion) may be part of the problem. There’s not much a person can do about their height to change the squeaking. But they can be advised to avoid activities or movements that cause the squeaking. That’s a bit tricky for a priest who must genuflect (bend on one knee down and up) or kneel repeatedly. Whenever possible, replace kneeling with bowing. When genuflecting is required, try using the other leg as the bending side. And if possible, find the range-of-motion that is squeak-free and stay within that range. This may mean you don’t go down as far when genuflecting. Sometimes, it’s not the patient at all but rather the way the implant was placed in the hip. The wrong angle, a slight twist of the cup (socket) piece, or a little bit of both has been linked with squeaking.But the most likely factor is the implant itself and in particular, the materials it is made of. The newer implants made of titanium alloy are more flexible and less stiff. This feature could increase the vibrational force that creates friction and squeaking. Other contributing factors include loss of fluid lubricating the hip, tiny particles of metal or other debris from the implant, or damage to the surface of the implant.See your surgeon, if you are unable to find ways to avoid the squeaking. A simple revision surgery may be all that’s needed. Replacing the liner or altering soft tissue tension could make all the difference.

I’m heading into arthroscopic surgery. What kind of recovery should I expect?

December 29th — admin

I’m heading into arthroscopic surgery for my right hip. The surgeon is going to take a look around but for sure remove some pieces of cartilage that are floating around in there. What kind of recovery or rehab should I expect?

Hip arthroscopy is becoming a more common orthopedic procedure now with more and more hip injuries among the athletic crowd. Better imaging technology has also made it possible to find what’s wrong or what’s causing painful symptoms. Loose bodies in the joint is just one of the many reasons why arthroscopic procedures are used so successfully.But you are right — there is a postoperative program. And it’s important that patients complete this program in order to restore full joint motion, strength, flexibility, and function.The specifics of the program depend somewhat on the type of surgery that was done. For example, removing free-floating debris in the joint is a much simpler procedure than repairing deep holes in the cartilage. Likewise, repairing a torn labrum (fibrous rim of cartilage around the hip socket) may only require a simple home program. But there are some procedures that take longer to recover from and involve a slower pace of recovery.And competitive athletes will follow a four-step process of rehab progression. These four phases include 1) mobility and initial exercise, 2) intermediate exercise and stabilization, 3) advanced exercise and neuromotor control, and 4) return to activity.A physical therapist will show you what to do, how to do it, and how to advance or progress the program. You will probably start out on crutches for the first week to 10 days and gentle active motion of the hip. When you have full motion, the exercises assigned next are designed to restore strength and normal contract/relax sequences of all the muscles around the hip.Core (pelvis and trunk) stabilization exercises are recommended next along with balance training. And finally, if you are active in a sport or specific activity, you’ll be shown how to prepare to return to that sport. The goal is to participate fully without fear of reinjury.

Is a labra tear with impingement diagnosis really that complicated?

November 8th — admin

I finally got a diagnosis for my hip pain: a labral tear with impingement. Seems like they did every imaginable test to figure it out. Is it really that complicated?

The hip is a fairly complex joint. Problems that often seem like they are in the hip really originate from the low back, sacroiliac joint, and even the knee. True hip pain usually occurs in the groin and front of the thigh. But even knowing the problem is in the hip doesn’t identify the true cause. It could be the soft tissues in and around the joint, the articular cartilage inside the joint, or the rim of cartilage around the rim of the hip socket called the labrum.When the labrum is tored, frayed, or damaged in some way, it can get pinched between the head of the femur and the acetabulum (hip socket). This pinching or impingement is what causes the groin pain, loss of hip motion, and sometimes grinding, catching, or locking sensation with certain hip motions. Labral tears can be especially difficult to diagnose because there are often other changes going on in the hip at the same time. The physician relies on a standard physical exam, history, and then special tests to sort it all out. Joint range-of-motion, strength, and a postural assessment provide helpful information. The patient’s report of what makes it better and what makes it worse is also very useful.There is also a pain test that can be done. The surgeon injects a numbing agent similar to novocaine into the hip joint. If the pain goes away, it’s an indiction that the source of the pain is coming from inside the joint. If the pain doesn’t go away, it could still be something around or just outside the joint.But X-rays and sometimes MRIs are often needed to confirm the presence of a torn labrum. And even then, it isn’t until the surgeon performs an arthroscopic exam that the true extent (and possibly cause) of the problem are uncovered.

I’m just starting to research the idea of a metal hip joint resurfacing procedure. What can you tell me about this treatment?

April 29th — admin

I’m just starting to research the idea of a metal hip joint resurfacing procedure. What can you tell me about this treatment?

Hip resurfacing arthroplasty is a type of hip replacement that replaces the arthritic surface of the joint but removes far less bone than the traditional total hip replacement.

Because the hip resurfacing removes less bone, it may be used for younger patients. Hip joint resurfacing is a good idea for those who are expecting to need a second, or revision, hip replacement surgery. The need for a revision operation increases as they grow older and wear out the original artificial hip replacement.

During the procedure, the femoral head is dislocated out of the socket. Special powered instruments are used to shape the bone of the femoral head so that a new metal surface will fit snugly like a cap on top of the bone. The cap is held in place with a small peg that fits down into the bone. The hip socket may stay the same, but more often it is replaced with a thin metal cup.

The patient must have enough healthy bone to support the cap. The metal materials hold up well under the increased activity of a younger adult group of patients. There is a lower risk of hip dislocation after joint resurfacing compared with a total hip replacement. This may be because the fit is so much closer and better for hip resurfacing.

There have been some problems with metal-on-metal hip joint resurfacing. For example, tiny pieces of metal can fleck off the implant with prolonged wear and tear. Those metal ions can create irritating debris in the joint contributing to increased wear and tear.

Long-term reports of metal-on-metal hip resurfacing are fairly limited in number. Future research efforts are needed to observe the natural history after hip joint resurfacing and report on long-term results.

One study after 12-months reported a 75 per cent satisfaction rate. But this means that one-quarter of the patients were not happy with the results. Factors contributing to suboptimal recovery are unknown. It could be a lack of rehabilitation after the operation. It could be a different type of rehab is needed for hip joint resurfacing.

Tear in ligament often revealed only through arthroscopic surgery

September 30th — admin
I was in a car accident and broke my pelvis in two places. After the injury finally healed, I still had deep groin pain and my hip kept giving out on me. I had MRIs, X-rays, and CT scans done for my pelvis, and nothing ever showed up. Finally, I had arthroscopic surgery and the doctor found a tear in the ligamentum teres. Where is this and why doesn’t it show up on all these tests?

 
If you pull a chicken leg out of its socket, you’ll see a fibrous white ligament. That’s the equivalent of the ligamentum teres in the human. It helps hold the head of the femur (thigh bone) in the hip socket.

Traumatic or twisting injuries can cause this ligament to tear. Hip dislocation can stretch it to the tearing point, too.

Doctors don’t have a test to help them find this type of tear. In fact, it wasn’t until arthroscopic surgery came along that they even knew it occurs as often as it does. Now that we know it’s a problem, more studies will be done to find easier ways to diagnose it.
