Overview l.jpg

Named for Birmingham, England, where the device’s creators practice medicine

Used globally since 1997; More than 65,000 implanted

Approved by the FDA in March 2006

In an international study of 1,626 hips, 99.5% of patients were “Pleased” or “Extremely Pleased” with the results of the BIRMINGHAM HIP Resurfacing (BHR) System.

Overview


Who is the typical candidate for bhr system l.jpg

Adults under age 60 for whom total hip replacement may not be appropriate due to an increased level of physical activity

Active adults over age 60 may be candidates, depending on their bone quality

Who is the typical candidate for BHR*System?


Anatomy l.jpg

Socket be appropriate due to an increased level of physical activity

Ball

Femoral neck

Smooth weight-bearing surfaces

Smooth cartilage

Femur

Anatomy


Diseases of the hip l.jpg

Diseases of the hip be appropriate due to an increased level of physical activity


Osteoarthritis oa l.jpg

“Wear and tear” arthritis be appropriate due to an increased level of physical activity

Joint becomes pitted, eroded, uneven…and painful

Bone spurs, or osteophytes, often form

The common activities of daily living become limited by extreme pain

Osteoarthritis (OA)


Hip dysplasia l.jpg

Congenital disease that affects 1 in 1,000 people be appropriate due to an increased level of physical activity

The hip doesn’t develop the normal wear patterns, which leads to early OA

Chief risk factor: family history

Women, first-born children and breech babies have higher rates of dysplasia

Hip dysplasia


Avascular necrosis avn l.jpg
Avascular necrosis be appropriate due to an increased level of physical activity(AVN)

  • Caused when there is a disruption of the blood supply to the hip

  • In time, the bone will die and the femoral head will collapse

  • Leading causes: Alcoholism, corticosteroids

  • Other risk factors: blood vessel blockage due to sickle cell anemia or fat particles, or from dislocation of the hip due to trauma


Non surgical alternatives l.jpg

Non-surgical alternatives be appropriate due to an increased level of physical activity


Non surgical alternatives10 l.jpg

Lifestyle modification be appropriate due to an increased level of physical activity

Exercise and physical therapy

Anti-inflammatory medication

Non-surgical alternatives


Risks l.jpg

Risks be appropriate due to an increased level of physical activity


Risks12 l.jpg
Risks be appropriate due to an increased level of physical activity

  • Thromboembolism

  • Infection

  • Pneumonia


The procedure l.jpg

Conventional vs bhr resurfacing l.jpg
Conventional vs. BHR be appropriate due to an increased level of physical activity*Resurfacing


Conventional vs the bhr system l.jpg
Conventional vs. the BHR be appropriate due to an increased level of physical activity*System

Total hip cuts

BHR System cuts


Is it minimally invasive l.jpg

Is it minimally invasive? be appropriate due to an increased level of physical activity


That depends on how you define minimally invasive l.jpg

Soft Tissue be appropriate due to an increased level of physical activity

No. Incision length of 6 to 8 inches

Bone

Yes. Preserves your body’s natural bone structure; It resurfaces rather than replaces

Conserved bone

That depends on how you define “Minimally Invasive.”


The implant l.jpg

The implant be appropriate due to an increased level of physical activity


The key benefits l.jpg

Head size be appropriate due to an increased level of physical activity

Advanced bearing surface

Bone conservation

The key benefits


Head size l.jpg

Closely matches the size of your natural femoral head be appropriate due to an increased level of physical activity

Larger than the head of a total hip replacement

Larger head means a reduced chance of dislocation after surgery—a leading cause of revision surgery

1-3% of total hips dislocate over the lifetime of the implant

0.3% of BHR* implants dislocated in the first 5 years after surgery (in a study of 2,385 hips)

Head size

Total hip head

BHR head

Healthy head


Advanced bearing surface l.jpg

Metal-on-metal implant be appropriate due to an increased level of physical activity

No plastic liner like most total hip replacements

All-metal total hip replacements reduce joint wear by 97% versus metal on plastic total hips; BHR* implants were found to be in this range

Plastic

Metal

Advanced bearing surface


Bone conservation l.jpg

Preserves your be appropriate due to an increased level of physical activitynatural femoral neck

Neck length and angle determine accurate leg length

With the BHR*System, you retain your original equipment; with a total hip, your femoral neck is replaced by the implant

Bone conservation

Hip with osteoarthritis

Bone cuts fora traditionalhip replacement

Bone cuts forBHR System


Bone conservation cont l.jpg

Revises to a primary be appropriate due to an increased level of physical activity

If you need “revision” surgery, you don’t get a revision implant

The follow-up procedure would be the same total hip replacement you would otherwise have received

Bone conservation (cont.)


After surgery l.jpg

After surgery be appropriate due to an increased level of physical activity


After surgery27 l.jpg

You will undergo a rehabilitation protocol be appropriate due to an increased level of physical activitysimilar to total hip replacement patients

During year-one: Low-impact activities as your bone and muscles adjust to the new stresses (swimming, walking, bicycling)

After year-one: Higher impact physical activity may be appropriate (singles tennis, jogging)

After surgery
