Design Rationale

The Science of Simplicity “ he advanced features of the CORAIL® Stem, T and its bone-preserving surgical technique, have made it a great choice for minimally invasive hip surgery. More than thirty years ago, we began a revolution with the use of HA in orthopaedics. Today we face an exciting new era, and we look forward with confidence in sharing continued success with the world’s orthopaedic community.” ARTRO Group - Design Surgeon Team, Clinique d’Argonay International Visitation Centre - Annecy, France US Surgeon Team James Caillouette, MD; Charles R. Clark, MD; Mark Froimson, MD;...

Low-profile lateral shoulder design enables easy insertion in reduced incision techniques, including the anterior approach Available in collared and non-collared options Step geometry is designed to convert hoop stresses to compressive loads Tapered neck geometry and ARTICUL/EZE® Hip Taper designed to increase range of motion Multiple offset options aiming to restore hip biomechanics Vertical/horizontal grooves designed to provide rotational and axial stability “ ’ve used the CORAIL since 1998 and with its easyI to-use surgical technique, choose to use it on many types of patients,...

Proven Fixation The CORAIL Stem stepped geometry is oriented to reduce shear forces and improve compression loading in host cancellous bone. Proximal trapezoid cross section resists axial/torsional stresses and promotes initial stability. Distal quadrangular cross section provides rotational stability without cortical contact

Enhanced Biomechanics Corail Coxa Vara Corail STD 135° STD 125° Coxa Vara Stem Axis Corail STD Corail High Offset Corail Coxa Vara Corail STD 135° STD 135° High Offset Collarless and Collared Stem Options Short Neck, Standard Offset, and High Offset stems are available in both Collarless and Collared options to provide surgeons with options based on their preference. High offset options add +7mm of offset through direct laterilization to restore hip biomechanics in a wider range of patients. Collared Stem Options Coxa Vara High Offset option is available in a Collared version only. Coxa...

Neck Enhancements Narrowed anterior-posterior neck dimensions and optimized ARTICUL/EZE Taper increase range of motion and reduce risk of mechanical impingement. ARTICUL/EZE 12/14 Taper is fully captured by all nonskirted ARTICUL/EZE Heads, eliminating the creation of a false skirt due to trunnion protrusion. Polished neck is designed to generate less wear debris secondary to prosthetic impingement. “I use the CORAIL because of its ease of implantation and long track record. Used with the PINNACLE® Acetabular Cup System, it lets me select multiple options in order to optimize hip...

Bone Preserving Philosophy Compaction Broaching A philosophy of respecting and preserving patient anatomy, biology and physiology are key to the CORAIL Stem success. Compressing and compacting the cancellous bone during the broaching process maintains the medullary canal endosteum, preserving blood supply to the bone and the bone/implant interface. Compaction broaching creates an excellent bone/implant contact ratio and high pullout strength, and it increases prosthetic torsional stability.3 Compaction broaching preserves the blood supply to promote healing and growth of bone around the...

“Compaction broaching coupled with CORAIL creates ‘silent’ hip replacement. We haven’t seen any adverse, long-term radiographic changes.” James Caillouette, MD - Newport Beach, California “I find the CORAIL Stem and instrumentation facilitate ease of insertion using an anterior approach.” Joel Matta, MD - Los Angeles, Cali

Heritage The fully HA-coated CORAIL Total Hip System can be used in a variety of types and sizes of femora. Type A: Champagne Flute Type B: Proportional Shape “I find it to be reproducible and easy to implant, and use it on many different types of patients.” Sam Sydney, MD - Baltimore, Maryland “After independently reviewing the ARTRO Group CORAIL data in 1998, I decided to try the CORAIL Stem. I’m pleased with the results and now use it on many types of patients.” Mark Froimson, MD - Cleveland, Ohio
