Product Overview
Inventors of Dual Mobility
Over 35 years of clinical history, more than any other Dual Mobility system.
The SERF Novae® Dual Mobility system is an acetabular bearing designed for both primary and revision total hip arthroplasty, offering increased stability and range of motion3 for patients at high risk of hip dislocation, femoral neck fracture, osteonecrosis of the femoral head, revision procedures where other treatments or devices have failed, or other related complications.
The first dual mobility concept was defined in the early 1970’s by Gilles Bousquet, Professor in Orthopaedics at the University Hospital of St. Etienne (France) and the first implantations were in 1975. Bousquet's historical series shows a dislocation rate of < 0.7%, verifying the potential to perform successfully and reduce the risk of dislocation.
Seamless Articulation
Unique innovation designed to increase high range of motion with less risk of dislocation.
The SERF Novae® Dual Mobility Cup construct consists of a cementless, solid back, stainless steel cup, polyethylene insert and a femoral head component. Together, these components result in a dual mobility device with two points of articulation— one between the polyethylene insert and metal cup (external bearing), and the other between the polyethylene insert and femoral head (internal bearing). Primary point of motion occurs at the internal bearing, providing the opportunity to minimize wear and improve longevity of the implant.
Clinical Advantages
Dual Mobility system has potential to restore stability, increase range of motion, and reduce risk of dislocation.
The polyethylene insert is available with shell sizes ranging from 43mm to 63mm outer diameter, providing increased jump distance - the distance a head must travel to dislocate after impingement. The greater the jump distance, the greater the stability of the hip; thus helping to reduce the risk of dislocation.4
Based on laboratory testing, when compared to a conventional total hip arthroplasty with the same cup size, the SERF Novae Dual Mobility Cup provides greater jump distance and increased range of motion.
