Summary
Custom 3D-printed Trabecular Titanium (TT) hip implants offer improved outcomes for complex revision surgeries. These patient-specific implants significantly enhance pain relief, function, and joint mobility, restoring biomechanical parameters effectively.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- Medical Device Technology
Background:
- Hip revision surgery following multiple previous reconstructive procedures presents significant challenges.
- Customized implants may offer a viable solution for complex acetabular reconstruction.
- 3D printing technology enables the creation of patient-specific implants with intricate designs.
Observation:
- Four patients (2 male, 2 female) underwent acetabular revision using custom Trabecular Titanium (TT) implants manufactured via 3D printing.
- The mean age of the patients at the time of surgery was 51.5 years.
- Clinical and radiographic follow-up was conducted for a mean duration of 43.5 months.
Findings:
- A significant improvement in the mean Harris Hip Score was observed, increasing from 13.9 preoperatively to 75.8 at the final follow-up.
- Patients reported enhanced pain relief, improved function, and greater joint mobility.
- Radiographic assessment revealed no signs of implant instability, migration, or tilting.
Implications:
- 3D-printed custom Trabecular Titanium implants demonstrate efficacy in complex hip revision cases.
- The use of patient-specific implants and surgical tools facilitates good clinical results.
- This technology effectively restores biomechanical joint parameters in challenging revision scenarios.
