Cup Positioning Guide

for Total Hip Arthroplasty

Cup positioning is perhaps the most critical step in THR. Due to visibility challenges in THR the conventional method of reaming and position may have its limitation. We offer the cup positioner guide in form of  pin references  placed on peripheral of acetabulum which is perfectly aligned with desired version and inclination angle. Surgeon can use these reference for aligning the reamer. Key features of our products are :

Visualize

  • Making 3D visualization available on our website in shortest possible time after DICOM been uploaded
  • Optimizing the scanning technique for better segmentation outcome
  • Customization of 3D model based on surgeon’s feedback

Plan

  • Accurate 3d version and inclination angle calculation
  • Cup size templates for better decision making
  • Wall thickness analysis

3D print

  • Providing range of physical sizing template
  • Using unique propitiatory technique of printable planning we ensure all the valuable planning information engraved in the model
