Overview

Comparative analysis shows patient-specific guides enhance translation and operative efficiency in scaphoid non-union repairs.

Key Points

  • This research compares patient-specific instrumentation to conventional techniques for scaphoid reconstruction.
  • Retrospective analysis of 115 scaphoid reconstructions (89 cases included)
  • Comparison of 45 cases with patient-specific instrumentation and 44 using conventional techniques
  • Assessment of distal-fragment rotation and translation using a Cartesian coordinate system.
  • PSI achieved greater absolute correction in distal-fragment rotation parameters.
  • Sagittal flexion improved by 8.9° with PSI compared to 5.8° with conventional, p = 0.007.
  • Ulnar inclination significantly improved by 3° with PSI, p = 0.017.
