PRODUCT FEATURESHip & Knee SurgeryThe Tradition Hip SystemThe BioPro® Tradition Hip carries on CharlesTownley, M.D.’s Horizontal PlatformSupport design philosophy.The implant is designedto be physiologicallystress loaded and incorporatesa platform perpendicularto theresultant forces ofbody weight and muscleforces. The design isintended to eliminateadaptive bone remodelingand stress shielding,which is a known causeof bone loss followingjoint replacement. Thetime tested designcomes in porous coatedand non-porouscoated versions in three differentlengths and thirteen sizes.The extra-short stem, or the LivingHip, is an ultra-short femoral stem availablein nine sizes with a minimal increase inlength, ranging from 95 mm to 115 mm in length. Due to the shortlength, the stem does not extend into or beyond the natural anteriorbow of the femur. This allows for increased proximal fill withresultant increased stability proximally.The ultra-short stem helps address the issue of thigh pain. Theelasticity of bone is greater than that of metal. If a stem extendsinto the anterior bow, the femur bends around the implant, causingirritation and pain. The Living Hip is proximal to the area ofthe bend, causing minimal irritation to the femur.BioProTel: 800-252-7707www.bioproimplants.com/hips.phpVascuTherm Iceless ColdTherapy, Compression and DVTProphylaxis TherapyThe VascuTherm by ThermoTek delivers a unique and proprietarythermal compression therapy solution in one easily transportabledevice.

The coating, whichreportedly produces less wear and releases significantly fewer metal ions than CoCr, will be applied toAesculap's Columbus knee.The seven-layer coating is composed primarily of Zirconium Nitride, a durable ceramic material thatcreates a harder and more durable surface than traditional implant materials. In ISO wear testing, the surfacehas shown wear rates of just 3.5 mg/million cycles. ISO-certified laboratory testing also indicated thatthe release of Ni ions has been significantly reduced. Additionally, the design of the seven-layer coatingaids in the prevention of mechanical ablation, a separation of the coating from the substrate, which may bea shortcoming of some mono-layer coatings.The Columbus knee system features a full portfolio of AS-coated components, including Femur and Tibiacomponents as well as Tibial Augments and Stems.Aesculap Implant Systems, Inc.Tel: 866-229-3002www.aesculapimplantsystems.comNovember/December 2009 • ORTHOPAEDIC PRODUCT NEWS 47
