Product Overview
The ICONACY I-Hip offers a comprehensive total hip system that utilizes clinically proven geometries with advanced material technologies to provide a simplified, contemporary solution for the patient, surgeon, and hospital.
Key Features:
Clinically Proven Geometries
• Modernized tapered wedge femoral stem design used more than 30 years
• Designed for axial stability by creating cortical bone contact both at the medial and lateral endosteal cortices
• A complete and comprehensive offering of offsets in femoral stem and femoral head designs
Historically utilized poly liner locking mechanism with over 20 years of use
• Cup-to-head ratio designed to gain the largest size femoral head within a given cup without sacrificing bearing thickness
• Cup provided with a “Ring Secured” locking ring that will not spin during insertion and an industry leading secured torque and lever out ratio’s with a intraoperative
Large diameter head (36mm) promote increased stability
• For an identically placed cup and stem, a larger head provides increased range of motion before impingement and reduces the risk of dislocation
• Clinical studies show that large diameter heads (i.e., 32mm and greater) can be used to reduce the rate of dislocation
Advanced Material Technologies: Third-generation, highly cross linked (i.e., HXL) UHMWPE
• In vitro test results indicate acceptable wear rates with 36mm (I.D.) X 54mm bearing
• Cold Irradiated Mechanically Annealed (CIMA) hxl PATENTED technology with the potential for improved mechanical strength
Porous, titanium plasma spray coating provides initial press fit stability
• Cementless, titanium hemispherical socket fixation designs have historically had excellent clinical results at 8- to 10-year follow-ups
• Femoral components with circumferential porous coating have historically performed well in patients at an average follow-up period of 8 years
Contemporary Implant Designs: Recognized femoral stem design with progressive features offer surgical adaptability
• Designed to Gradually Transition between selected sizes by increasing in all dimensions as the size selected increases
• Narrowed femoral neck designed to allow increased range of motion before impingement
• Shortened femoral stem lengths (i.e., 15-20% less than historic designs with this geometry type) to accommodate various surgical approaches
Fully coated hemispherical cup designed for biologic fixation
• Familiar 180-degree hemispherical, forged Ti-6Al-4V alloy cups
• 2 & 3 hole cups (3 hole version approved) in both standard and finned provide immediate fixation with fins or cancellous bone screws. The ring is designed to eliminate “spinning” during the insertion process
Modular femoral heads facilitate functional versatility with various intraoperative bearing options
• Ceramic and Cobalt Chrome femoral heads available in 28mm, 32mm, and 36mm diameters to assist with ensuring adequate fit and stability
• Cobalt Chrome femoral Femoral heads in 5 different offset lengths (28mm, with short, medium, and long, with 32/36mm in short, medium, long and extra-long) to restore proper biomechanics and leg length
Simplified Instrument System: Friction-lock acetabular insert trials
• Acetabular insert trial friction interface to cup permit intraoperative flexibility during joint trial reduction
• Reduced trialing steps without the need for a screw to secure insert trial to cup, in situ
Intraoperative femoral stem offset selection with modular neck trials
• Modular neck trials in standard, lateral and reduced lateral offerings for intraoperative use from the top of the femoral stem rasp
• Fail-safe, “keyed” interface feature ensures that only the correct modular neck trial is matched to the associated femoral stem rasp
Dependable acetabular cup impactor
• 4-point tip provides enhanced, “blind” securing of impactor-to-cup for quick intraoperative capture and locking
• Solid lock interface to promote predictable cup placement
Condensed and comprehensive (flexible) set
• Complete instrument set condensed to three, double-stacked trays
• Instrument layout developed and aligned by acetabular and femoral prep for surgical simplicity (http://www.iconacy.com)
Surgical Technique: Acetabular Cup
