Mastering Precision in Implant Placement
Achieving precise implant positioning in total hip arthroplasty (THA) demands significant surgical skill. For the direct anterior approach (DAA), studies suggest a steep learning curve of around 100 cases before mastery. Navigation technologies have been shown to improve accuracy and reduce reoperation rates for dislocation, with inertial portable navigation systems (INS) offering additional benefits such as shorter operation times, simplified handling, and enhanced placement precision.
Evaluating INS as a Training Tool
This study explored whether the use of INS navigation (Navbit Sprint®) could improve acetabular implant placement accuracy among orthopaedic trainees, and whether repeated use would also enhance their manual skills over time. By tracking performance during a training rotation, the research aimed to assess INS as both a clinical and educational tool for developing surgical expertise in THA.
