Should soccer player get hip joint resurfacing?

October 13th — admin

I’m a 45-year-old avid soccer player. But my right hip is wearing out. If I go for the newer hip joint resurfacing, how soon could I get back on the field?

Hip joint resurfacing was introduced several years ago to help younger patients who are more active and who would likely dislocate or wear out a total hip replacement. Surgeons found a way to replace the surface of the joint without removing the bone and replacing the entire joint. Bone is saved because the femoral head (round ball at the top of the thighbone) isn’t cut off. And it isn’t necessary to put a long stem down into the canal of the femur since the head isn’t replaced. All of these features of joint resurfacing make it possible for patients to extend the life of their own joint before a full joint replacement is needed.

There is also some thought that joint resurfacing may preserve a more normal load transfer during gait (walking and running). If that is true, gait recovery could be added to the list of advantages for joint resurfacing over total hip replacement.

These are just a few of the many reasons why joint resurfacing has advantages over a total hip replacement for younger, more active adults. Research is underway to find ways to further maximize these benefits. Scientists are studying all aspects of the implant design, surgical technique, and rehab protocols.

Each surgeon has his or her own way to perform the operation. The approach, type of implant, incisions made, and fine-points of surgical technique can vary. So, it’s the surgeon who ultimately must answer your question. You don’t want to do anything to compromise what would otherwise be a perfect result.

You can expect at least a 12 week postoperative recovery time. Six months of concentrated rehab is not unreasonable for someone who wants to participate in competitive sports such as soccer. Ask your surgeon for a timeline to guide you. Make sure you understand what (if any) motions or activities are not advised and how long these restrictions should last. Participation in high-impact activities may be always restricted in order to protect and preserve the joint for as long as possible. Find out what your particular restrictions may be when making your final decision about this procedure.

Size matters in reducing hip dislocations

October 11th — admin

I was raised by my grandparents and now find myself helping to take care of them as they get older. Grandad had a hip replacement two months ago that just won’t stay in the socket. The surgeon wants to take it out and put one in with a larger femoral head. It seems to me that a larger head in the small socket would make the problem worse instead of better. Can you explain this to me?

A larger femoral head size has been shown to reduce hip dislocations and minimize instability. There are several reasons why they work.

First, they provide a larger surface area in contact with the acetabular cup (socket).

Second, a larger head gives a better ratio of size from the head of the femur to the neck. That’s important in allowing a larger arc of motion and preventing impingement or pinching of the femoral neck against the rim of the cup.

The surgeon usually puts a polyethylene (plastic) liner inside the cup (between the cup and the femoral head). With this liner in place, the larger head can sit deeper inside the cup, making it more difficult for the head to jump out of the cup and dislocate. Studies have verified that a thinner liner can hold up while still accommodating the larger femoral head. And improved materials have extended the wear on these heads. That’s important because larger heads do tend to wear more potentially reducing their long-term survival.

Finally, larger heads can potentially eliminate the risk of early dislocation with implants of all kinds (e.g., ceramic, metal-on-metal, polyethylene). That makes them useful for a large variety of patients who need a hip replacement or revision surgery such as your grandfather requires.

What happens if a hip replacement dislocates?

October 6th — admin

My mother fell and dislocated her new hip replacement. They took her back into surgery and put the joint back in place. She’ll be going to a step-down transition unit. What should we expect for a prognosis? Will it hold? What happens if it doesn’t?

Dislocation is every patient’s fear after getting a new hip replacement. The surgeons call it instability. No matter what name you give it, the problem is troublesome for the patient and a complex challenge for the surgeon. Conservative (nonoperative) care is usually tried first. Once the hip is back in the socket, a brace may be applied and the patient is sent to physical therapy.

Not all surgeons use bracing in these situations. If they do, the brace used is called an abduction brace. It holds the hips apart and in a neutral position (not turned in or rotated out). The physical therapist will help your mother learn how to move safely while strengthening the muscles around the hip.

A special focus of treatment is to restore normal joint proprioception (sense of joint position) and kinesthesia (awareness of movement). Balance training is also very important. Before discharging her to home, the therapist will interview the family to find out what kind of changes need to be made at home. For example, throw rugs will have to be removed, additional lighting (especially for at night) may be needed, grab bars installed in and around the bathroom, and so on.

If a conservative approach doesn’t work and the hip dislocates again and again, then surgery may be needed. The surgeon may have to tighten up loose tissue and restore a balance to soft-tissue tension on all sides of the hip joint. If the implant is improperly positioned, it must be removed and realigned. The surgeon may need to replace the femoral head with a larger one. The goal is to prevent a recurrent (second) hip dislocation.

The good news is that only 10 per cent of patients who dislocate the hip after receiving a total hip replacement will dislocate it a second time. Your surgeon and the rehab team will help you navigate through this difficult time. Don’t hesitate to bring up your concerns and questions. They have knowledge of your mother’s health and hip condition that they can draw on to provide you with answers.

Hip resurfacing vs. hip replacement

October 4th — admin

I’m looking into the possibility of having a hip joint resurfacing procedure done instead of a total hip replacement. I’ve heard all about the positives of this operation from my surgeon. Could you fill me in on any down sides there might be?

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 preferable for younger patients that are expected to need a second, or revision, hip replacement surgery as they grow older and wear out the original artificial hip replacement.

You are asking, how well do they work? And what are the potential problems or complications? Using data from the 1000s of hips done outside of the United States along with studies done in the states, it’s clear that the overall revision rate is still higher for resurfacing than for standard total hip replacements. But the rate is still small enough to make it worth having the procedure for the many patients who aren’t ready yet for a complete total hip replacement.

The most common complications are femoral neck fracture, implant dislocation, and metal ion hypersensitivity. Because the component parts of the implant are metal, tiny pieces of metal ions flake off and get trapped inside the joint forming a tumor-like cyst or entering the blood stream. This could become a problem for anyone with metal hypersensitivity.

Studies show that women are more likely to have a failed resurfacing procedure. So are patients who’ve had a previous hip surgery or anyone who has osteonecrosis (loss of blood supply to the top of the femur or thighbone causing death of bone cells). And anyone with inflammatory arthritis or developmental dysplasia of the hip is at increased risk for implant failure.

Joint resurfacing is a stop-gap measure for patients with painful arthritic conditions. By preserving as much bone as possible, it buys them some time before converting to a total hip replacement. This plan allows younger patients to remain active and put off the inevitable hip replacement.

Fast-track program for hip replacement

September 30th — admin

Have you ever heard of a fast-track program for total hip replacements? That’s what my father is on, and we are just wondering what it means.

Patients and surgeons are both interested in a speedy, painless recovery from surgery after a total hip replacement. To reach that goal, surgeons have introduced something called a minimally-invasive surgery (MIS). Minimally invasive surgery refers to any operation where the surgeon changes how long or how deep the cut is made into the tissue. With some minimally invasive approaches, the surgeon can avoid cutting into most of the muscles around the hip that are normally removed from the bone during the standard hip replacement surgery. The hope is that with less trauma to the soft tissues (especially the muscles around the hip), the patient will be able to recover that much faster.

There are also some efforts to speed up the rehab or postoperative recovery process. A program called the fast-track has been designed to accomplish this. Several studies have shown that patients who are on the fast-track after surgery get better faster. The fast-track means they get a patient-controlled pump to manage their pain. They start rehab sooner, and the therapist provides a more aggressive program. In studies so far, patients in the fast-track groups are discharged sooner, can walk better, and are more satisfied than patients following the standard rehab protocol. This is true no matter what type of incision or approach was used to do the surgery.

Not everyone can participate in a fast-track program. Patients are selected based on general health, motivation, and compliance level. Complications after surgery such as infection, dislocation, or fracture can put an end to someone’s fast-track status. But for those who are able to complete the program, the results have been very impressive.

Patient wants tiny incision

September 28th — admin

I’m going to have a total hip replacement next week with the new minimally invasive surgery. The surgeon has explained how this is to my advantage, but mostly, I’m just interested in having a tiny incision. Am I going to be sorry I didn’t have the standard type of incision? Will my vanity come around and bite me in the butt, so-to-speak?

You’re not alone in your concern about form over function. Even if the minimally-invasive approach doesn’t yield better functional outcomes, patients like how it looks. A shorter incision just looks better, and patients are asking for that. Patients also want an implant that will last as long as possible. And that factor is more important to them than the length of the scar or how long they are in the hospital.

There are many advantages to a minimally-invasive approach. And we’re not talking about just a shorter incision line. Minimally invasive refers to the fact that the group of muscles usually cut to remove the old hip joint aren’t touched. The gluteus maximus (buttock) muscle is split to get to the hip joint, but the length of the split is much shorter. The incision into the joint capsule is also smaller and repaired without any negative effects.

Studies are ongoing to assess the results of minimally-invasive surgeries. There are mixed reviews as to outcomes. In some studies, the operating time is shorter and there’s less blood loss. In others, the operation is complex and may take more time if the surgeon hasn’t done quite a few of them. But the long-term results (a year or more later) don’t really show much of an advantage of the minimally invasive approach over the standard incision. Walking distance, walking speed, and muscle strength appear to even out between the two surgical approaches. There are still plenty of factors to consider when comparing the two approaches. Patient education, preoperative counseling, analgesia, and rehabilitation programs may be the real keys to recovery. While the surgical approach might make a difference, there’s at least enough preliminary information to suggest that the postoperative treatment process may be equally (if not more) important.

Soccer player chooses surgery for snapping hip syndrome

September 20th — admin

After a very long and unsuccessful attempt at treating my snapping hip syndrome, I finally decided to have surgery to release the hip tendons on both sides. I’m hoping to be through rehab by the time soccer season starts again. How long does it take to get my full strength and motion back?

Some athletes are bothered by a painful snapping at the hip when moving the leg from a flexed to an extended position. There can be a variety of reasons why this happens. Some occur outside the joint such as when a tendon rubs over a bony prominence. Others are caused by something going on inside the joint. It could be a tear in the labrum (rim of cartilage around the hip socket) or a loose fragment inside the joint. The most common cause is the iliopsoas tendon rubbing over a bony bump called the iliopectineal eminence. Many times there is also a fraying or a tear of the labrum contributing to the problem.

Whatever the cause, treatment is needed to help the athlete get back into action. At first, conservative care with rest, stretching exercises, and antiinflammatory drugs is advised. A nonoperative approach should be tried for at least six months. Sometimes a steroid injection with a numbing agent into the iliopsoas bursa helps. When none of these approaches reduces or relieves painful snapping symptoms, then surgery may be advised. The surgeon can partially or fully cut the iliopsoas tendon away from the bone. The tendon retracts and reattaches to the nearby soft tissue.

Recovery and rehab takes at least 10 to 12 weeks. At first, you won’t be able to bend the hip. This makes you unstable when trying to walk or use coordinated movements of the legs. This new symptom will last two to four weeks until the tendon reattaches and heals in its new location. You’ll be given some simple exercises to do at first. You will probably work with a physical therapist who will supervise how much weight you put on the leg(s), how to use crutches or canes, and a progression of leg control exercises. Eventually stretching exercises will be included, then coordination exercises, and finally, sport-specific movements. When you can control your motion, have 90 per cent strength, and can handle impact activities, then you will be released to return to the soccer field.

What is a cervical hip fracture?

September 14th — admin

Have you ever heard of a cervical hip fracture? What is that? I thought the cervical bones were in the neck, not in the hip.

There are many types of hip fractures, usually named for their location. A basic understanding of the hip anatomy will help visualize where the fractures occur.

The hip joint is one of the true ball-and-socket joints of the body. The hip socket is called the acetabulum. It forms a deep cup that surrounds the ball of the upper thighbone, or femoral head. The femoral head is attached to the rest of the femur by a short section of bone called the femoral neck. A bony bump on the outside of the femur just below the femoral neck is called the greater trochanter. A smaller bony bump on the femur called the lesser trochanter is located on a diagonal from the greater trochanter.

These two bumps on the femur are where some of the hip muscles attach. A cervical hip fracture refers to the fact that the break is inside the joint itself. Either the top of the femur (called a subcapital fracture) or the acetabulum (hip socket) have a break. Another term for the location of these fractures is intracapsular or cervical.

When the break affects the hip, but is not right inside the hip, the fracture is referred to as an extracapsular hip fracture. The fracture may occur in the neck of the femur (femoral neck fracture), between the two trochanters (intertrochanteric fracture), or in the main shaft of the femur just below the lesser trochanter and may extend down the shaft of the femur. This last type of hip fracture is called a subtrochanteric fracture.

Dislocate hip to fix it?

September 12th — admin

I saw a surgeon who wants to do surgery to dislocate my hip in order to fix it so it won’t keep pinching the joint cartilage when I bend and rotate my leg. I’m thinking, no thanks. Is there a better way to take care of this problem?

It sounds like you might have a condition called femoroacetabular impingement (FAI). With FAI, the top of the femur (thigh bone) pinches the rim of the hip socket. The area that gets compressed is referred to as the acetabular rim. This type of impingement occurs most often when the hip is flexed and internally rotated.

Surgery is often recommended as the most successful treatment for this problem. There are three surgical choices: 1) surgical hip dislocation, 2) periacetabular osteotomy, and 3) hip arthroscopy. Surgical hip dislocation is considered the current gold standard, though some experts expect improved arthroscopic techniques will change that in the future. Surgical dislocation refers to taking the femoral head out of the socket and making adjustments and repairs as necessary, and then putting the head back in place. The operation can be done without cutting through the muscles and with the least amount of trauma possible.  Any damage to the labrum (rim of cartilage around the hip socket) can be repaired. Any problems with mismatch of the femoral head and neck with the acetabulum (hip socket) can be taken care of. This type of surgery allows for preservation of the joint, which is important in young, active adults.

Periacetabular osteotomy corrects the retroversion (tipped or tilted position of the acetabulum). The capsule surrounding the hip joint is cut open. The femoral head and neck are reshaped by shaving or cutting off portions of the bone. The goal is to correct the placement of the femoral head in the hip socket.

The third surgical option (hip arthroscopy) to treat FAI allows the surgeon to gain access to the inside of the joint without cutting it open. This avoids pulling the femoral head away from the socket. Arthroscopic surgery also makes it possible to reattach (rather than remove) a torn labrum.

Studies show that the best way to approach this problem is by restoring as normal hip anatomy as possible. Surgical hip dislocation is used with good success for patients with mild to moderate (but not severe) degeneration of the joint cartilage, surface, and surrounding capsule. It sounds like your surgeon is right on track with current evidence for best practice. You can always seek a second opinion to help you understand your condition and the various treatment options available.

Even loose-jointed yoga instructor has hip pain

September 8th — admin

I am a yoga instructor with a very painful hip. I can’t figure it out because my joints are very loose. But every time I flex my hip past 90-degrees or try to cross my legs, I get a very sharp pain deep in my hip. What could be causing this?

Hip pain with limitations on full hip motion in an active adult requires special attention — especially if you are in your 20s or 30s. Early diagnosis and treatment is imperative to avoid degenerative changes in the hip joint later in life. There are many possible causes of this type of hip pain.

Given your description, one of the most likely would be femoroacetabular impingement (FAI). Femoroacetabular impingement (FAI) describes a condition where the top of the femur (thigh bone) pinches the rim of the hip socket. The area that gets compressed is referred to as the acetabular rim. This type of impingement occurs most often when the hip is flexed and internally rotated. For a long time, it was believed that FAI only occurred in people with some kind of abnormal anatomy of the hip. There was either a backward tilted angle of the hip socket called retroversion, a larger socket than the ball (head of the femur) inside the socket, or flattening of the femoral head. One type of abnormal shape of the hip was labeled a pistol grip because of the resemblance to the grip of a handgun.

More recent studies have shown it’s possible to develop FAI even when the hip structure and anatomy are essentially normal. But, in general, more people with acetabular retroversion end up with hip pain and problems leading to degenerative hip osteoarthritis than any others.

To get to the bottom of the cause of hip pain, a thorough history and examination are required. An orthopedic surgeon is the best one to see. The physician will look at your foot position, leg angles, leg length differences from one side to the other, hip motion, and muscle strength. Gait (walking) patterns will be evaluated. Special tests such as the impingement test are done to identify the presence of an underlying FAI as the cause of the painful symptoms and restricted motion. X-rays, CT scans and/or MRIs may be used to confirm the diagnosis.

The results of all of these tests are important pieces of information when deciding on the best treatment approach. With early diagnosis and treatment of young, active patients with FAI the problem can be managed by conservative measures. Surgery may be needed to restore as normal hip anatomy as possible. But before jumping to any conclusions, make an appointment and see a specialist to find out for sure what might be causing the problem. If you’ve had this for a while and it hasn’t gone away (even with your yoga practice), don’t wait any longer.
