    AbstractThe scaphoid bone is essential for wrist stability, force transmission, and movement, being crucial for maintaining carpal kinematics. In cases where the scaphoid is non-reconstructable, a complete replacement can serve as a treatment option to preserve carpal alignment and motion. This approach has evolved since its first descriptions in 1945, benefiting significantly from advancements in patient-specific implant design, additive manufacturing/3D printing, and material use in recent years. We present a technique for scaphoid replacement using a patient-specific prosthesis and reconstruction of intrinsic and extrinsic ligaments to achieve optimal stability and mobility.© 2024.
