1. Treating Osteoarthritis Through the SuperPath® Hip Replacement

2. What Are The Major Causes of Joint Pain?
Osteoarthritis
Post Traumatic Arthritis
Rheumatoid Arthritis
Avascular Necrosis
Paget’s Disease
Systemic Lupus
Trauma

3. What is Arthritis? “Arthritis” literally means “joint inflammation”
Arthritis refers to over 100 diseases that cause:
Joint Pain
Joint Stiffness
Joint Swelling
Symptoms worsen with age
Affects more than 50 million Americans
Two most common forms of arthritis:
Osteoarthritis
(Degenerative Joint Disease)
Rheumatoid Arthritis

4. Arthritis in the Hip
Normal Hip
Arthritic Hip

5. Osteoarthritis
Osteoarthritis (OA) is a degenerative joint disease in which the cartilage covering the ends of the bones deteriorates.
Most common form of arthritis
Affects 27-million Americans
Usually found in knee, hands, or hips
Contributing factors:
Advanced age
Weight
Lack of exercise
Previous injury
Cause is unknown

6. Osteoarthritis of the Hip
Healthy Hip
Arthritic Hip
Ligaments
Femur
Diseased Femoral Head
Pelvis
Femoral Head

7. Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disease which causes chronic swelling of the joints
May also affect tissues around joints May lead to destruction of cartilage, bone, and ligaments Typically found in several joints in body at once (systemic) Hands, wrists, feet, knees are most common Affects approximately 1.5 million people in the United States* Is 3 times more common in women than men Cause is unknown

8. Existing Treatments Change of lifestyle Modify alcohol consumption
No physically demanding jobs
Reduction in physical activity
Increase stretching and flexibility
Weight reduction
Anti-inflammatory medications

9. Existing Treatments Total Hip Replacement
Historically very successful procedure
Over 10,000,000 hips have been implanted globally
Aging demographic driving up number of implants
Treatment option more prevalent for younger patients (40s-50s)
*Millenium Research Group Report, 2005

10. Total Hip Replacement Purpose: Relieve pain and restore mobility
Performed routinely since 1960’s
Approximately 300,000 performed each year in U.S.*
Hip replacement implants are designed to replicate the anatomy
*Millennium Research Report. 2011

11. Total Hip Replacement Healthy Hip Post-Surgery Acetabular Cup
Ligaments
Femoral
Stem
Femur
Pelvis
Femoral Head

12. Materials Used to Make Total Hip Replacements
UHMW Crosslinked Polyethylene – Replaces cartilage and has optimal wear characteristics
Cobalt Chrome
Harder than titanium.
Used in articulating surfaces.
Titanium
Biocompatible
Modulus of Elasticity= flexibility is closer to host bone.
Surface promotes bone contact
Note: The same basic materials have been used for 30+ years

13. Total Hip Surgical Procedure: Traditional
Incision
Femoral Head Cut
Femoral Implant
Acetabular Cup

14. General patient concerns with THR
Traditional THR Concerns
Pain
Discomfort
Post-operative recovery
Return to normal life

15. What is the SuperPath® Approach?
This approach addresses typical THR concerns. The SuperPath® hip technique is a tissue-sparing approach where no muscles or tendons are cut. The SuperPath® approach requires none of the typical postoperative restrictions to your hip range of motion.

16. SuperPath® vs. Typical Posterior Approach

17. Total Hip Surgical Procedure
The SuperPath® Hip Technique vs.Traditional Posterior Hip Technique
SuperPath® Incision: inches*
*Incision size will vary but the SuperPath advantage is its gentle treatment of your joint tissues.
Traditional Incision: 8-10 inches

18. Why the SuperPath® Hip Technique?
Fast Hospital Recovery†
Muscle-preserving technique
No typical hip movement restrictions
It’s possible to walk within hours of surgery.

19. Fast Forward back to the things you love!
Fast hospital recovery
Muscle-preserving technique
No hip movement restrictions after surgery

20. Indications / Contra-Indications
The hip joint is worn and torn due to the natural aging process, trauma, rheumatic diseases or deformity
Fracture or ischemic necrosis
Correcting or replacing a previous operation, e.g.: joint reconstruction (osteotomy), fusion, segmental or total hip arthroplasty (THA)
Contra-Indications
Acute/chronic local or systemic infection
Severe diseases of muscles, nerves or blood vessels that could endanger limbs.
Inadequate bone stock around the joint, making it difficult or impossible for implantation
Joint disease which may require alternative reconstruction (osteotomy)
Youth with immature skeletons
Hepatitis or HIV infection
Local bone tumor or bone cyst
For additional risks, please consult your doctor.

21. Possible Risks
Component risks from having a Hip Replacement include: allergic reaction, loosing of the components, wear, corrosion, dislocation, breakage, and revision.
Other Risks
Progressive bone degenerations (osteolysis)
Infection, delayed healing
Drop in blood pressure during surgery
Bruising or nerve damage
Unstable, loose joint
Extra bone formation
Limited mobility or range of motion
Broken bone or bruising of knee cartilage during surgery
Unintended shortening/lengthening of the leg
Aggravated problems of either leg due to complications
Pain
For additional risks, please consult your doctor.
