overview
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
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
Socket

Ball

Femoral neck

Smooth weight-bearing surfaces

Smooth cartilage

Femur

Anatomy
osteoarthritis oa
“Wear and tear” arthritis

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
Congenital disease that affects 1 in 1,000 people

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
Avascular necrosis (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

that depends on how you define minimally invasive
Soft Tissue

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 key benefits
Head size

Advanced bearing surface

Bone conservation

The key benefits
head size
Closely matches the size of your natural femoral head

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
Metal-on-metal implant

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
Preserves your natural 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
Revises to a primary

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 surgery27
You will undergo a rehabilitation protocol similar 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
