Biarticular Head characteristics
The biarticular head, also called a bipolar or bicentric head, was essentially designed to reduce the friction that occurs, in the majority of cases and early on, in the acetabular cartilage upon direct contact with the metal head of an endoprosthesis in a classic hemiarthroplasty.
The biarticular or bipolar system from Surgival is indicated for hip hemiarthroplasty in which the primary objective is to preserve the anatomical acetabulum and its joint cartilage. The design of this bipolar system offers the option for dual rotation thanks to the combination of two spherical geometries that help reduce friction and increase the life of the joint cartilage and, therefore, of the system.
The Biarticular Head is made up of a metal cup that is in contact with the acetabulum and a polyethylene insert that receives the femoral head for the stem. This therefore creates two joints: one between the acetabulum and the cup, and another between the insert and the femoral head.
The biarticular system is made up of the biarticular cup, the biarticular insert and the femoral head.
