Revision acetabular prosthesis Bencox® Mirabo Cup

cementless

Two-in-one cup bearing system ­Ceramic and PE liner Secure Locking Mechanism ­Patented locking mechanism allows for secure fixation with superior congruency for push-out, rotation and tilting. Surface treatment option: TPS coating and Laser 3D coating ­Clinically proven Ti-Plasma Spray Coating World 1st laser 3D Coating Technology Secure Peripheral Fixation of Cup. ­Flattened dome establishes physiological load transfer throughout the periphery of the cup 2.Acetabular Exposure and Reaming The acetabular rim must be exposed, and the remains of the capsule must be cleaned. Initiate the reaming with a small, starting reamer to deepen the acetabulum all the way to the medial floor of the acetabular fossa, while at the same time, retaining the subchondral bone in the superior region of the acetabular dome. The whole cartilage should be removed, along with the osteophyte on the acetabular fossa, and the osteophyte on the rim. It is advisable to use reamers in 1-2 mm increments when approaching the definitive acetabular size. During the reaming procedure, hold the reamer in the same direction in which the acetabular cup will be implanted. Clean the acetabulum of all remaining cartilage and soft tissues, down to the bleeding subchondral bone. 3.Positioning of the Acetabular Cup Trialing The quality of press fit can determine whether the real cup is appropriate, using the trial acetabular cup. It is important to understand that all Bencox Cup system is marked with true dimensions. (54mm trial cup is same as real cup 54mm in diameter) Insert the 1-2mm bigger size of trial cup than last reamer into the reamed acetabulum.
