Scaphoid replacement with patient-specific prostheses offers a solution for non-reconstructable scaphoid bone injuries. This technique aims to restore wrist stability, carpal alignment, and motion, improving patient outcomes.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Hand Surgery

Background:

  • The scaphoid bone is critical for wrist function, including stability, force transmission, and kinematics.
  • Non-reconstructable scaphoid injuries pose challenges to preserving wrist function.
  • Historically, scaphoid replacement has evolved, with recent advancements enhancing its efficacy.

Purpose of the Study:

  • To present a refined technique for scaphoid replacement using patient-specific prostheses.
  • To reconstruct intrinsic and extrinsic ligaments for optimal wrist stability and mobility.
  • To address the limitations of non-reconstructable scaphoid bone cases.

Main Methods:

  • Utilizing patient-specific implant design based on advanced imaging.
  • Employing additive manufacturing (3D printing) for prosthesis creation.
