The CORAIL Revision Stem is an evolution of the KAR™ stem, specifically for revision surgery.1-2 Manufactured from forged titanium alloy,3 it shares the CORAIL hip’s design rationale of stereostability, macro and micro surface detailing, HA coating, ARTICUL/EZE® 12/14 Mini Taper and is compatible with the range of DePuy Synthes’ High Performance Bearing options. The CORAIL Revision Stem offers the surgeon a range of stems for mild to moderate situations (types 2 and 3A of Paprosky’s Classification4) making it suitable for the majority of revision cases. The CORAIL Revision Stem is also indicated for primary implantation in a cavernous femur.
The surgical technique shares a similar straightforward procedure for implantation as the primary CORAIL stem. During femoral preparation, reamers are used to calibrate the distal cavity of the femur. Machined diamond-tooth broaches remove cement and/or debris and re-shape the metaphyseal region to a quadrangular envelope with the correct anteversion.
A trial stem is also used to allow verification of the correct preparation of the femur to ensure easy insertion of the final stem.
