Signature Duo

SCHALE MIT DUALER MOBILITÄT

Bewegung neu definiert

Verrenkung ist eine der häufigsten Ursachen für THA-Ausfälle bei Primär- und Revisionsverfahren.
Signature DUO, ein duales Mobilitätssystem von Biorad Medisys, wurde konzipiert, um einen größeren Bewegungsumfang zu bieten und das Risiko einer Verrenkung zu verringern. Es ist eine hervorragende Lösung sowohl für Primär- als auch für Revisions-THA, reduziert den Verschleiß und verbessert die Stabilität, ohne die natürliche Bewegung zu beeinträchtigen.

Signature Duo bietet aufgrund seiner einzigartigen Designphilosophie der dualen Mobilität mehrere Vorteile wie

  • Reduziertes Risiko von Verrenkungen
  • Höherer Bewegungsumfang
  • Reduzierte Verschleißrate

Frequently Asked Questions

What are the key features of the SIGNATURE DUO Cup?
The SIGNATURE Duo is a dual mobility cup designed to increase range of motion and reduce the risk of dislocation. Its acetabular cup features a plasma-sprayed titanium coating, four pegs, and four rows of serrations for fixation and rotational stability. The neutral liner uses XLPE and a chamfered edge to support longevity and higher range of motion.
What is the benefit of the plasma-sprayed titanium coating?
The SIGNATURE Duo acetabular cup has a plasma-sprayed titanium coating designed to provide primary fixation and support secondary bone integration. This coating creates a surface intended to facilitate biological fixation following initial implant stability, contributing to secure acetabular component fixation.
Who may benefit from a dual mobility hip replacement?
Dual mobility implants may be particularly beneficial for patients with an increased risk of hip dislocation, including selected patients undergoing revision THA. They may also be considered in primary THA where enhanced stability is clinically desirable. Patient selection depends on factors such as age, activity, anatomy, previous surgery, and individual risk factors.
Is a dual mobility hip replacement better?
Dual mobility hip replacement is not universally “better” than conventional hip replacement; its advantages depend on the patient and clinical situation. Evidence suggests dual mobility constructs can reduce dislocation risk while providing good functional outcomes, particularly in patients at higher risk of instability. The choice should be based on individual patient factors and the surgeon’s clinical judgment.
Does a dual mobility hip implant last longer?
Dual mobility implants are designed to provide low wear and long-term performance, and the SIGNATURE Duo uses an XLPE liner intended for reduced wear and greater longevity. However, current evidence does not establish that all dual mobility implants universally last longer than conventional hip implants. Implant longevity depends on factors including implant design, fixation, patient factors, surgical technique, and bearing wear.
