BIARTICULAR HEAD

Product catalog summary
Overview of Biarticular Head: The Biarticular Head, also known as Bipolar or Bicentric, is designed to reduce friction in the acetabular cartilage caused by the metallic head of an endoprosthesis in classic hemiarthroplasty. It consists of a metallic cup and a polyethylene insert, creating two articulations: one between the acetabulum and the cup, and another between the insert and the femoral head.
Specifications: The metallic cup is made of stainless steel (AISI 316 LVM) and comes in 15 sizes ranging from 41 to 55 mm. The polyethylene insert is made of ultra-high molecular weight polyethylene (UHMWPE) and is available in four sizes with an internal diameter of 28 mm.
Implants and Components: Various references are provided for different neck lengths and diameters of the femoral head, all made from stainless steel AISI 316 LVM. The document lists specific references for each size and type of component.
Surgical Technique: The procedure involves several steps, including femoral head exposure, osteotomy of the femoral neck, exploration of the medullary cavity, and implantation of the chosen stem. Trial reductions can be performed using trial heads and cups. The assembly of components is recommended to be done on the instrumentation table, but can also be done directly on the femoral stem if necessary.
Instrumentation: The document details a complete set of biarticular instrumentation, including trial heads, tester discs, positioner-extractor, mortising chisel, and extractor for biarticular inserts. It also includes references for various sizes of trial acetabular cups and other surgical tools.
Distribution and Contact Information: The document provides contact details for Surgival, the distributor, including addresses, phone numbers, and email addresses for their commercial and international departments.
