Hip Acetabular Cup

Name: Hip Socket Implant & Acetabular Cup for Total Hip Repair – Frigate
Price: 249.00 USD
Availability: InStock

Hip Acetabular Cup failure often results from micromotion that exceeds physiological limits, hindering proper bone ongrowth and long-term stability. To address this, the cup design incorporates a high-porosity titanium substrate combined with plasma-sprayed surface coatings that limit micromotion to under 50 µm.

Non-Destructive Testing

Ultrasonic Testing (ASTM E2375), X-ray Inspection (ASTM E2662), Dye Penetrant (ASTM E1417)

Technical Advantages

Securing a Hip Acetabular Cup in variable pelvic bone quality requires a fixation strategy that accommodates multiple trajectories and cortical interfaces. This Hip Acetabular Cup offers a multi-hole shell configuration with angularly distributed screw holes and threaded locking mechanisms, engineered for bicortical screw engagement. Load paths are optimized to reduce cantilever forces on the ilium, enhancing construct durability under high patient activity levels.

Hip Acetabular Cup performance is heavily influenced by the wear rate of the articulation interface. This system utilizes precision-machined internal geometry with sub-10 micron tolerances, compatible with cross-linked UHMWPE and ceramic liners. The taper-lock mechanism and anti-rotation features in the Hip Acetabular Cup mitigate micromotion at the liner-shell interface, significantly reducing wear particle generation and polyethylene creep.

Industry Applications

Orthopedic Joint Replacement Surgeries

Hip Acetabular Cup is used in total hip arthroplasty to restore joint articulation and load-bearing functionality.

Trauma and Fracture Management

Applied in post-traumatic hip reconstruction to stabilize acetabular defects and support femoral head articulation.

Revision Hip Arthroplasty

Utilized during complex revisions to replace failed or loosened primary implants, ensuring biomechanical restoration and implant longevity.

Osteoarthritis Treatment

Deployed to manage degenerative joint disease by replacing the damaged acetabulum and enabling low-friction joint movement.

Avascular Necrosis Cases

Implanted when femoral head collapse compromises joint stability, enabling effective articulation with the new acetabular interface.

Developmental Dysplasia Correction

Used to address congenital hip deformities by providing stable anatomical reconstruction and precise socket alignment.

Anatomical Fit and Geometric Modularity

Restoring the native hip biomechanics demands a Hip Acetabular Cup that adapts accurately to individual pelvic morphologies. This design provides hemispherical and asymmetric geometries with controlled polar offset to restore the center of rotation. Each Hip Acetabular Cup offers fine-size increments and low-profile rims to ensure complete bone contact while minimizing impingement risk during deep flexion.

Repetitive loading across millions of gait cycles subjects the Hip Acetabular Cup to complex stress states. Manufactured from HIP-processed Ti-6Al-4V ELI, this cup demonstrates superior fatigue resistance validated by ISO 7206 testing protocols. The bulk microstructure and optimized wall thickness of the Hip Acetabular Cup enable it to resist plastic deformation and failure under extreme torsional and axial loads.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure precise interference fit during Hip Acetabular Cup manufacturing?

Frigate uses high-precision CNC turning and 5-axis milling machines to maintain tight tolerances on outer diameters. These tolerances ensure a consistent interference fit in the acetabular cavity during surgery. Dimensional checks using CMM validate radial roundness and sphericity. This precision avoids micromotion and enhances implant longevity.

What surface treatments does Frigate offer for Hip Acetabular Cups to improve osseointegration?

Frigate applies titanium plasma spray or HA (hydroxyapatite) coatings using controlled thermal spray processes. These coatings increase surface roughness to enhance bone ongrowth. Scanning electron microscopy (SEM) is used to validate coating morphology and thickness. Consistent coating adhesion meets ASTM F1147 and ISO 13779 standards.

How does Frigate handle fatigue strength requirements for Hip Acetabular Cup shells?

Frigate uses FEA-based fatigue simulations to validate component performance under cyclic load scenarios. Material selection, typically Ti-6Al-4V ELI, supports high-cycle fatigue life. Manufacturing routes like hot isostatic pressing (HIP) reduce internal porosity. Finished parts undergo cyclic load testing per ISO 7206-4 to ensure compliance.

What post-machining inspections does Frigate perform on Hip Acetabular Cups?

Frigate uses coordinate measuring machines (CMM) for dimensional inspection of hemispherical geometry and locking groove features. Surface roughness is checked using profilometers, ensuring Ra values match surgical requirements. Dye penetrant testing is used to detect surface cracks post-machining. All measurements are recorded for traceability as per ISO 13485 standards.

How does Frigate validate the locking mechanism compatibility of the Hip Acetabular Cup with polyethylene liners?

Frigate performs assembly force testing to measure the push-in and pull-out forces of the liner-locking system. Precision gauges simulate liner insertion and assess deformation under mechanical stress. Finite element analysis verifies stress distribution around locking tabs. Compatibility tests comply with ASTM F1820 guidelines.
