Objective
To evaluate how robotic-assisted software, which considers pelvic movement, can improve implant positioning during total hip arthroplasty (THA).
Methodology
105 patients underwent robotic-assisted THA with dynamic modeling based on pelvic tilt and range of motion. The surgical plan's adjustments were tracked during the procedure.
Key Findings
- In 78% of surgeries, the original surgical plan was modified using robotic guidance.
- The robotic system helped adjust for individual spinal mobility types (stiff, normal, hypermobile).
- Many patients would have had their implants positioned outside traditional "safe zones" without robotic assistance.
Conclusion
Robotic tools that factor in patient-specific pelvic movement can significantly improve implant alignment during THA, reducing the risk of complications due to poor positioning.
What Does This Mean For Patients
If you're undergoing hip replacement surgery, robotic-assisted technology may help ensure more accurate implant placement, improving the long-term success of your procedure.
