Today, let's discuss the selection of implants and instruments during the revision process.

1.Revision Acetabular Cup:

HARMONY Acetabular Cup (Revision)

• Customized for Hip Revision patients
• Surface with dual plasma-sprayed Ti+HA coatings, unilateral coating thickness of 0.375mm for optimal initial press fit, clinically certified for over 15 years
• Designed for multiple liner options
• Mirror-polished inner cup surface with friction-reducing properties
• High dome support for maximum polyethylene-cup contact, minimizing micromotion and wear
• Perimeter and dome screw holes for immediate stability during surgery

3D SEE Trabecular Acetabular Cup (Revision)

• "Starry Sky" design for screw holes
• 9 peripheral and 6 dome screw holes evenly distributed for flexible intraoperative positioning
• Suitable for severe acetabular bone defects and irregularities
• Matching the design of the cup and bone cement high cross-linked liner: Allows adjusting cup placement based on acetabular condition and modifying anteversion and abduction angles within a safe range using bone cement liner to prevent dislocation
• Covers the requirements of various types of acetabular side revisions and complex primary replacements from size 48# to 66#

3D JCT Trabecular Acetabular Cup (Revision)

• 6 peripheral and 6 dome screw holes evenly distributed for flexible intraoperative positioning
• Titanium metal bone beam structure with excellent biocompatibility
• Outstanding initial stability: 1.08 coefficient of friction, close press fit design, 180° hemisphere design
• Excellent bone integration performance: 600-800μm pore size, 75%-80% porosity, 3D interconnected porous structure
• The cup and liner are connected and fixed by snap lock, compatible with existing HPE-10° and Harmony 10° liners to meet clinical revision needs
• Sealing without implanting screws to increase cup contact area and overall strength

1. Revision Supports with Wings

1. Revision Supports without Wings (Metal Hip Cup)

Metal Hip Cup with Winged Support:

• Groove-shaped design on the outer edge of the acetabulum for better adherence of the prosthesis to the acetabular rim, leading to improved postoperative outcomes. Differentiation between left and right sides conforms better to human anatomical characteristics, ensuring strong attachment.
• Posterior upper cement buttress to minimize unsupported cement, maximizing the cement's supportive function.
• Three-flange design enhances the fixation effect of the support and offers multiple screw options for increased stability.
• Thoughtful screw-hole arrangement to meet the implantation needs of various clinical cases.
• 3mm wing thickness facilitates intraoperative adaptability and shaping.
• Rough surface promotes optimal adhesion of bone cement and near-perfect bone bonding.
