Personalized Hip Solutions – Designed for Your Unique Anatomy

Hip pain. It’s personal.

Not only is your body different from anyone else’s, so is your pain.How your chronic hip pain affects you is unique to you and the way you live your life. That’s why at Stryker we’ve designed Personalized Hip Solutions. We have provided the following information to help you better understand how personal your hip solution can be.

A better fit for you.

Personalized Hip Solutions offer you and your doctor an extensive, technologically advanced, and customizable number of options for helping to get you and your hip functioning again. Your doctor can now choose, and more finely tune, very specific treatment options to meet your unique needs. Personalized Hip Solutions are designed to take into account every aspect of your lifestyle, your pain, your loss of function, your anatomy, your age, your gender and your overall health. Personalized Hip Solutions offer a wide combination of products, so your doctor can better match the implants to your unique anatomy and help you meet your lifestyle recovery goals.

Designing a Solution Around You

Personalized Hip Solutions from Stryker provide a portfolio of surgical products and advanced technologies from which your doctor may build a treatment approach for your unique anatomy and lifestyle. Whether you are a candidate for hip resurfacing or total hip replacement, these innovative technologies enable your doctor to better match your specific needs.

New Technology: Tritanium – the pure 3-D titanium surface that encourages excellent fixation through ingrowth.¹

Tritanium is a three-dimensional surface on the acetabular cup that helps hold the implant into the bone. The new Tritanium technology was designed to resemble trabecular bone, a type of spongy bone tissue that provides skeletal support.

Tritanium technology allows for bone to grow into the component¹ providing enhanced fixation.² Tritanium is made from commercially pure Titanium, and studies have shown that it improves bone ingrowth when compared to other alloys.³ This technology may be especially beneficial for patients with low bone density and the 55% of Americans age 50 and older diagnosed with osteoporosis.⁴

Cormet Hip Resurfacing – conserving bone for younger and more active patients.

Hip resurfacing is bone conserving – meaning more of your healthy bone is kept intact. In this innovative process, the end of the thigh bone (femur) is capped with metal covering – a strong cobalt chromium metal – much like the capping of a tooth. This fits neatly into a metal cup that sits in the hip socket.With hip resurfacing, there is a lower chance of dislocation than with total hip replacement.⁵

Anatomic Femoral Heads – designed for more natural fit and performance.

Stryker's Anatomic Femoral Heads are larger in size, similar to the top of your femur, so they are anatomically sized for more natural hip performance. The result is a total hip replacement designed to help minimize dislocation and increase your range of motion.

Femoral Stem Options – a variety of femoral stem options for a better fit.

Your doctor will consider several factors when determining the appropriate femoral stem for you. Design, as well as fixation, are two important considerations. Some implants require bone cement to help secure the implant in place. Others have special coatings that encourage your natural bone grow onto them⁶ helping achieve cementless fixation. The femoral stem your doctor chooses depends on your bone quality, age, and clinical factors as well as his or her preference. Some femoral stems, such as Accolade, have a slimmer profile for minimally invasive surgery.

Bearing Technologies – designed to be long lasting.

The durability of hip replacement depends on many things including patient weight, activity level and bearing surface. Scientifically, the bearing surface is defined as the two elements of the hip implant that are designed to glide together throughout motion – the femoral head and the acetabular insert. These advanced bearing technologies can help reduce wear:

X3

Stryker's patented advanced bearing surface, called X3, has demonstrated up to 97% decrease in wear in laboratory testing.⁷ This decrease in wear may extend the life of your hip implant.

Ceramic

In laboratory testing, Biolox delta ceramic is up to 50% stronger than earlier generation ceramics.⁸ The strength of this material allows manufacturing of increased sizes of femoral heads so your surgeon has a broader implant selection to choose a better fitting implant.

Ceramic-on-Ceramic

Alumina ceramic bearings have demonstrated significantly lower wear versus conventional plastic-on-metal hip systems in the laboratory.⁹ It is, therefore, anticipated that the improved wear characteristics of alumina ceramic may result in a longer lasting implant.¹⁰

Stryker® Orthopaedics Trident® Acetabular Inserts made of X3® UHMWPE (unsterilized), 721-00-32E, show a 97% reduction in volumetric wear rate versus the same insert fabricated from N2\Vac™ gamma sterilized UHMWPE, 620-00-32E. The insert tested was 7.5mm thick with an inner diameter of 32mm. Testing was conducted under multi-axial hip joint simulation for 5 million cycles using a 32mm CoCr articulating counterface and calf serum lubricant. X3® UHMWPE Trident® Acetabular Inserts showed a net weight gain due to fluid absorption phenomena but yielded a positive slope and wear rate in linear regression analysis. Volumetric wear rates were 46.39 ± 11.42mm³/10⁶ cycles for N2\Vac™ gamma sterilized UHMWPE inserts and 1.35 ± 0.68mm³/10⁶ cycles for X3® UHMWPE (unsterilized) Trident® Acetabular Inserts. Although in-vitro hip wear simulation methods have not been shown to quantitatively predict clinical wear performance, the current model has been able to reproduce correct wear resistance rankings for some materials with documented clinical results.^{a, b, c}
