XU Hip Joint System
The XU Hip Joint System is a comprehensive solution for total hip replacement, featuring diverse components and innovative designs to meet clinical requirements.
Component Diversity
Acetabular Implants
Surface Coatings & Configurations: Available in types such as titanium-coated (with/without holes), titanium-bead-coated (with holes), and titanium + hydroxyapatite (HA)-coated (with holes).
Liners: Support the "one cup with multiple liners" compatibility design, including ceramic liners and XPE liners (0°/20°), enabling flexible matching with different ball heads.
Ball Heads
Materials & Types: Offer metal ball heads (cobalt-chromium-molybdenum alloy) and ceramic ball heads.
Sizes: Provide large-size options (e.g., 28mm, 32mm, 36mm, 40mm) to expand the range of motion.
Femoral Stems
Coatings & Types: Include titanium/HA-coated stems, titanium-bead-coated stems, cemented stems, titanium-coated stems, high-polish cemented stems, Type II cemented stems, and revision stems. These can adapt to different surgical scenarios (e.g., primary replacement, revision surgery).
Core Design Advantages
"One Cup with Multiple Liners" Design
A single acetabular cup can be matched with different types of liners (ceramic liners, XPE 0° liners, XPE 20° liners). This design has the following features:
Easy installation: Equipped with high-edge markers to provide installation guidance.
Enhanced stability: The 20° high-edge design prevents dislocation.
Support for personalized configuration: Liner types can be adjusted according to the patient's specific conditions.
Large-Size Ball Heads
Expanded Range of Motion: Large-size ball heads delay cup-neck impingement, effectively reducing collisions between hip joint components and improving hip mobility (the larger the ball head size, the higher the mobility).
Diverse Material Options: Available in cobalt-chromium-molybdenum alloy and ceramic, meeting different requirements for durability and biocompatibility.
Cobalt-Chromium-Molybdenum Alloy Bipolar Head (Integrated Component)
Material & Surface: Made of cobalt-chromium-molybdenum alloy with a micron-level high-polish surface, reducing friction with the acetabulum.
Mechanical Design: Transfers the shear force between the acetabular cartilage and the prosthesis from the outer cup of the bipolar head to the liner, significantly reducing relative movement at the interface between the bipolar prosthesis and the acetabulum.
Anti-Rotation Design: The integrated structure minimizes micromotion between the outer cup of the bipolar head and the liner.
Clinical Flexibility
The system adopts a modular design (diverse components, compatible matching), enabling personalized solutions for primary hip replacement, revision surgery, and different patient anatomical structures. This improves surgical adaptability and long-term efficacy.
