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 http://www.cdc.gov/chronicdisease/resources/publications/aag/arthritis.htm

Arthritis in the Hip Normal Hip Arthritic Hip

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 www.arthritis.org

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 www.arthritis.org

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 http://www.cdc.gov/chronicdisease/resources/publications/aag/arthritis.htm

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

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

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

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

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.

SuperPath® vs. Typical Posterior Approach

Total Hip Surgical Procedure The SuperPath® Hip Technique vs.Traditional Posterior Hip Technique SuperPath® Incision: 2.5-3.5 inches* *Incision size will vary but the SuperPath advantage is its gentle treatment of your joint tissues. Traditional Incision: 8-10 inches

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. † Chow J, Penenberg B, Murphy S. Modified Micro-Superior Percutaneously-Assisted Total Hip: Early Experiences & Case Reports. Curr Rev Musculoskelet Med (2011) 4:146-150

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.

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.
