Tantalum metal cups and augments versus custom-made 3D-printed trabecular titanium implants for Paprosky 3A and 3B acetabular defects: mid-term results.

Key Points

• The aim is to compare the effectiveness of tantalum metal cups and 3D-printed titanium implants for severe acetabular defects.
• Compared two implant types: tantalum metal cups and custom 3D-printed trabecular titanium implants.
• Assessed mid-term survival rates and functional outcomes post-surgery.
• Measured surgical time for both implant types.
• Both implant types demonstrated excellent survival rates for acetabular defects.
• Custom 3D-printed implants resulted in better functional outcomes compared to tantalum cups.
• Patients with 3D-printed implants experienced shorter surgical times.
