Objective
To evaluate the impact of robotic-assisted THA software incorporating dynamic pelvic tilt and range of motion on implant positioning accuracy.
Methodology
Prospective study of 105 patients undergoing robotic-assisted THA with intraoperative adjustments based on individual spinal mobility and pelvic dynamics.
Key Findings
- Intraoperative plans were modified in 78% of cases due to robotic guidance.
- The system accounted for variable spinal mobility (stiff, normal, hypermobile).
- Without robotic assistance, many implants would have been placed outside established “safe zones.”
Conclusion
Robotic-assisted THA that factors in patient-specific pelvic kinematics improves implant alignment and may reduce complications related to malposition.
What Does This Mean for Providers?
- Incorporating robotic guidance with virtual range of motion can optimize implant positioning, particularly in patients with altered spinal biomechanics.
- This technology aids in personalized surgical planning, potentially decreasing postoperative instability and implant failure rates.
- Providers should consider robotic assistance to improve surgical precision and long-term outcomes in THA.
