  2. 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

  3. 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?

  4. Socket Ball Femoral neck Smooth weight-bearing surfaces Smooth cartilage Femur Anatomy

  5. Diseases of the hip

  6. “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)

  7. 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

  8. 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

  9. Non-surgical alternatives

  10. Lifestyle modification Exercise and physical therapy Anti-inflammatory medication Non-surgical alternatives

  11. Risks

  12. Risks • Thromboembolism • Infection • Pneumonia

  13. The procedure

  14. Conventional hip replacement Healthy hip Cuts Implant components Implanted

  15. The BHR*System Healthy hip Cuts Implant components Implanted

  16. Conventional vs. BHR*Resurfacing

  17. Conventional vs. the BHR*System Total hip cuts BHR System cuts

  18. Is it minimally invasive?

  19. 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.”

  20. The implant

  21. Head size Advanced bearing surface Bone conservation The key benefits

  22. 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

  23. 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

  24. 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

  25. 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.)

  26. After surgery

  27. 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
