Hip Replacement new development

People are living longer in the new century. They are more likely to outlive their hip replacements. Some materials for hip replacement although durable like metal on metal produced lot of side effects and were withdrawn. Researchers in their quest to discover newer material have now developed a new acetabular liner for hip replacement. See the link below.

MMATech  Ltd, developing an acetabular liner for total hip implants, produced with a revolutionarynovel, advanced, low-friction and wear-resistant polyimide material, will be opening an investment round after excellent clinical results in recent pilot studies.

An acetabular fracture refers to a broken hip socket. It results after road traffic or domestic accidents. Mostly young people are involved.  The initial treatment consists of internal fixation. When this fails, hip arthritis results.  This is called secondary osteo-arthritis. Acetabular fractures are a leading cause of hip arthritis in young people.
The head of the femur ( ball)  also develops avascular necrosis. When arthritic pain ensues, hip replacement becomes necessary. Total hip replacement has been the standard treatment. It can address the concerns of shortening. We have introduced short stem hip replacements as an option. This has the advantage of preserving bone stock. As these patients are young, they may require a redo operation later. Hence it is preferable to use durable implants & preserve bone.
Hip replacement in these patients is technically difficult and is best done by surgeons with lot of experience in acetabular fractures and arthroplasty.

We demonstrate  few cases here.  These patients underwent hip replacement.  Uncemented or cementless implants were used. Bone grafting was done. Please refer to the PDF link.http://www.scribd.com/doc/106726026/Hip-Replacement-in-neglected-Acetabular-fractures for more information.
In our series, both conventional and short stem hip replacements have been used. Uncemented or cementless hip arthroplasty was preferred.
Bone grafting has been done in two cases. A variety of bearings were used. These were ceramic on metal, ceramic on ceramic, metal on poly. Hard bearings are preferable in these young patients as they can last longer. All patients regained pain free mobility, restored limb length within three months after surgery.

Avascular necrosis treatment with stem cells in India

Avascular necrosis of the hip Stem cell cure for bone problemsis a frequently seen condition in young patients. It is of diverse origin and its treatment is controversial. Surgical treatment remains the key stone in late cases with hip replacement as the proved and tested method. Surgeons at the Madras Joint replacement center are proud to announce a novel form of biological treatment with stem cells. It can be performed for patients with the early stages of the disease.
When the disease is detected early by MRI scans, it is possible in India now to perform a biological treatment.

In fact a biological treatment option of early disease is a medical necessity and must be the treatment of choice whenever possible.

A novel approach to this condition is being mooted by a leading Orthopedic surgeon in Chennai, India. This is by means of stem cells. Stem cells have the potential to regenerate any tissue. In this case, bone forming stem cells are utilized to synthesize new bone over the dead bone. Stem cells are harvested from the pelvis of the patient.

There are two techniques being promoted. One is a three stage procedure and the other is a single stage procedure. Both procedures are done in India, implying that you will save thousands of dollars in treatment costs.

The first method is by stem cell culture in the lab to multiply the number of cells several million fold. These cultured stem cells are reinjected into a previous core decompression site.

In the second method, bone marrow obtained from the pelvis is centrifuged in the operating room to yield a Bone marrow concentrate rich in stem cells. These are injected into a core decompression site.

A paper presented at the recent American academy of surgeons meet in New Orleans highlighted the success story of stem cells.

Hip arthritis – Types & solutions

Hip arthritis is of two types. Young and middle aged persons suffer from secondary osteoarthritis. Primary osteoarthritis can affect middle aged and elderly. Surgery in this group of relatively younger patients requires newer techniques like hip resurfacing.

Hip Resurfacing is the preferred option in young & middle aged males with primary

Types of Hip arthritis

Hip arthritis is classified as Primary and secondary Osteoarthritis.

Primary osteoarthritis is age related wear and tear arthritis. It is rare in India.

Secondary osteoarthritis occurs at a younger age and is more common. Rheumatoid arthritis, avascular necrosis, traumatic arthritis and other connective tissue disorders like SLE, Psoriasis etc. all lead to secondary osteoarthritis.

Rheumatoid arthritis is an auto immune disorder, affects all joints particularly the small joints but also does not spare the hip and knees.

Avascular necrosis is a condition that reduces the blood supply to the end of the bone. It affects patients with excess alcohol intake, consuming steroids, connective tissue disorders like SLE. Systemic lupus erythematosus (SLE) is a connective tissue disorder affecting mainly young women A photo sensitive rash on the cheeks, renal involvement and arthritis are some notable features. Avascular necrosis affects a proportion of the patients with SLE.

Gaucher’s disease is a rare genetic storage disorder.

Post traumatic arthritis occurs after a severe injury to the hip. Fractures of the ball (top of the femur) or socket (acetabulum) can lead to arthritis after inadequate treatment.

Hip arthritis is very disabling as it is a small ball and socket joint. In advanced disease a total hip replacement was recommended by Orthopaedic surgeons until recently. The ideal age for a hip replacement is 74 years.

Surgical solutions

are the mainstay of treatment as conservative measures fail to relieve pain. Total Hip replacement (THR) is a time tested operation and has a success rate of 93 % survivor ship at 10 years.

Who needs a hip resurfacing?

In India, many young patients with ankylosing spondylitis, avascular necrosis, post septic arthritis, post injury suffer from hip arthritis and are advised a hip replacement for disabling pain. Thus many hip replacement operations are performed in younger patients. The surgery should cater to the enhanced demands on an artificial joint by younger and more active patients. Naturally an operation designed for Western elderly patients is not suitable for younger patients.

Hip resurfacing vs replacement

Hip Resurfacing vs Hip Replacement

In this operation the ball shaped upper end of the thigh bone (femur) and the socket (acetabulum) are replaced. The ball is replaced with a long metal stem that is fixed into the upper end if the thigh bone. Its upper spherical end articulates with a cup shaped polyethylene socket that is cemented into the pelvis.

Conventional hip replacements sacrifice a great deal of normal bone as the head, neck, and upper part of the thigh bone is removed for implantation of the prosthesis. Moreover wear debris from the poly-etheylene liner lead to osteolysis and bone loss. When this first hip is to be changed or revised after its lifespan more bone loss occurs. Conventional hips have a small ball to reduce friction and wear, but the ill effect of this is an increased risk of dislocation. An average dislocation rate of 3- 4 % has been reported. These implants do not last very longer than 20 years and revision rates of 50% at 20 years have been reported. Survival rates are less satisfactory for the relatively younger active patients. Thus a total hip replacement is not an ideal implant for younger patients less than fifty years old who need a new hip.

Problems with conventional total hip replacement:

  • Excessive bone sacrifice and loss
  • Increased risk of dislocation
  • Patients cannot squat or sit cross legged on the floor with out the risk of dislocation.
  • Range of movement is less
  • Patients cannot involve in sports
  • Poor survival in young and active patients they require earlier revision.
  • Revision surgery is difficult
  • The hip feels less like a normal hip
  • The cup wears with time and plastic from it harms bone
  • Change in length of the leg after surgery leading to leg length discrepancy.

Why remove normal bone when only the surface of the ball is bad?

This is the logic behind hip resurfacings. This bone preserving hip resurfacing involves replacing only the diseased bony surfaces of the head of femur and acetabulum. This involves sculpting the head of the femur and covering it with a metal cap and fixing an uncemented socket into the acetabulum to receive the head.

Hip Resurfacing- A bone preserving hip replacement!

Preservation of bone and less stress shielding makes it easy to revise this hip if needed. The large head size provides a very stable joint and recreates the sensation of a normal hip joint. Patients have gone back to playing Judo and Squash after this operation. Advances metallurgy makes the metal on metal articulation likely to survive longer in the young and active patient. With less metal inside the bone and less invasion of the medullary cavity of the femur, the risk of infection is reduced. Rehabilitation is faster and better.

Advantages of hip resurfacing:

  • Allows the patient to squat and sit cross legged on the floor safely
  • Allows a normal range of movement
  • Sacrifices only the surface diseased bone and preserves normal bone
  • Imparts a more normal sensation
  • The joint is likely to last longer even in younger and active patients.
  • Earlier and faster rehabilitation
  • Less risk of dislocation
  • Easier to revise if needed.
  • No leg length discrepancy.

In summary a Hip Resurfacing offers several advantages in young patients in young patients.

Hip resurfacing surgery- who needs it?

Are you suffering from hip arthritis? Has your surgeon advised you a hip replacement?Hang on! If you need a hip replacement, please read the following information on facts about the operation and a more advanced bone preserving option called hip resurfacing.

What is the hip joint? Watch video on hip joint anatomy and hip replacement operation

The hip joint is a ball and socket joint which connects the torso to your legs. It is formed by the upper end of the thigh bone ( femur) and the socket of your pelvic bone ( acetabulum). A natural shock absorber tissue called “articular cartilage” lines the ends of the bones and allows painless smooth movements.

What are the symptoms of hip arthritis?

The patient complains of pain and restriction of movement. Pain may often be felt in the knee alone with no hip symptoms. Occasionally the pain may be felt more in the buttock area rather than in front of the groin. Gradually you will loose your ability to retain a active life style through exercise and sports.

Diagnosis

Your doctor may advise x rays on which hip arthrosis is seen as a loss of joint space or narrowing of the gap. Loss of this lining shock absorber articular cartilage results in pain while you walk.

Treatment options

Initially your doctor may prescribe you pain killers and suggest you to perform exercises to retain flexibility of your joints.

When you have run out of non operative options like pain killers, physical therapy your orthopedic surgeon might advise you to seek a hip replacement.

The hip joint may need to be replaced with an artificial joint when it is irreversibly damaged and cannot be salvaged by alternate surgery. The patient complains of pain and restriction of movement.

Who needs a hip replacement?
In India, many young patients with rheumatoid arthritis, ankylosing spondylitis, avascular necrosis, post septic arthritis, post traumatic arthritis, are advised a hip replacement for disabling pain.

Thus many hip replacement operations are performed in younger patients. The surgery should cater to the enhanced demands on an artificial joint by younger and more active patients. Hip replacement is a successful operation for patients above 60 years

What is a total hip replacement?

In this operation the ball shaped upper end of the thigh bone (femur) and the socket (acetabulum) are replaced. The ball is replaced with a long metal stem that is fixed into the upper end if the thigh bone. Its upper spherical end articulates with a cup shaped polyethylene socket that is cemented into the pelvis.

Thus a total hip replacement is not an ideal implant for younger patients less than fifty years old who need a new hip. It is however the best option in elderly people.
Problems with conventional total hip replacement:
A total hip replacement is an excellent & time tested operation in the elderly. However in the young problems may arise. These are
(1) Excessive bone sacrifice and loss
(2) Increased risk of dislocation
(3) Patients cannot squat or sit cross legged on the floor with out the risk of dislocation.
(4) Range of movement is less
(5) Patients cannot involve in sports
(6) Poor survival in young and active patients they require earlier revision.
(7) Revision surgery is difficult
(8) The hip feels less like a normal hip
(9) The cup wears with time and plastic from it harms bone
(10) Change in length of the leg after surgery leading to leg length discrepancy.

Video shows comparison of Hip replacement and hip resurfacing

This is the logic behind hip resurfacing. This bone preserving hip resurfacing involves replacing only the diseased bony surfaces of the head of femur and acetabulum. This involves sculpting the head of the femur and covering it with a metal cap and fixing an uncemented socket into the acetabulum to receive the head.
What is Hip Resurfacing?
It is a bone preserving hip operation. In this operation only the worn out surface at the top of the femur bone is scraped and shaped into a cylindrical form from a spherical form. A metal spherical cap is glued or cemented over the cylindrical stump like a tooth crown over an old stump.
This restores the normal shape & size to the upper end of the thigh bone. Next the socket in the hip bone is scraped into a hemisphere. A metal cup is impacted after complete cartilage removal. This cup will integrate with the body’s bone on the back side as it has a layer of the same material as bone. The hip shape is thus restored to normal. Bone is preserved in the head of the thigh bone. If a hip resurfacing were to fail for some reason, it would be still possible to change this to a conventional hip replacement later on.
Preservation of bone and less stress shielding makes it easy to revise this hip if needed. The large head size provides a very stable joint and recreates the sensation of a normal hip joint. Patients have gone back to playing Judo and Squash after this operation. Advances metallurgy makes the metal on metal articulation likely to survive longer in the young and active patient. With less metal inside the bone and less invasion of the medullary cavity of the femur, the risk of infection is reduced. Rehabilitation is faster and better.

(4) Imparts a more normal sensation
(5) The joint is likely to last longer even in younger and active patients.
(6) Earlier and faster rehabilitation
(7) Less risk of dislocation
(8) Easier to revise if needed

So in conclusion although total hip replacements remain an excellent option in a specific elderly age group, Hip replacement alternatives like Hip surfacing should be strongly considered in young and middle aged patients ( less than 60 years) requiring a hip replacement in India.
