Short-term findings of a custom-made 3D-printed titanium partial scaphoid prosthesis and scapholunate interosseous ligament reconstruction

Abstract

Following wrist trauma due to a karate accident, an 18-year-old male patient developed non-union of the scaphoid with proximal pole necrosis and significant scapholunate gap from an evident scapholunate interosseous ligament (SLIL) injury. A custom-made 3D-printed titanium implant was used for scaphoid replacement and SLIL reconstruction. Good clinical and radiographic outcomes were observed at his 2-year follow-up. Custom-made 3D-printed titanium implants are thought to provide a surgical solution for patients requiring site-specific scaphoid replacement while allowing the reconstruction of the scapholunate ligament.
