3D-printing medical device company ZSFAB has reported the first clinical use of its Cervical Interbody System for anterior cervical discectomy and fusion (ACDF).
Dr Fernando Villamil, an orthopaedic surgeon, used the system in the clinical procedure at the Center for Orthopedic Reconstruction and Excellence (CORE) Hospital in Jenks, Oklahoma, US.
Villamil is the chairperson of ZSFab medical advisory board. He is also the leading surgeon in the cervical and lateral design teams.
Villamil said: “The design of the ZSFab Cervical Interbody device allows for bony ingrowth with its optimized lattice throughout and for generous biologic material placement, without sacrificing strength or subsidence performance.”
The ZSFab Cervical Interbody System comprises a porous titanium implant which was produced using additive manufacturing. The implant comes with an improved triply periodic minimal surface (TPMS) lattice structure to lower subsidence and enhance stress distribution.
The cervical implant also features rigid teeth on the inferior and superior surfaces to prevent migration following its insertion. In addition, the rigid teeth will increase the contact surface area with the vertebral endplates.

ZSFab is offering the interbody device in different sizes for ACDF.
The cervical interbody was already used in clinical cases in China before the first US clinical application.
ZSFab CEO Dr Jing Zhang said: “The device is designed with interconnected porous structures, engineered for bony integration, minimal debris, high fatigue strength and minimised subsidence.
“As we expand our spine solutions, our team is dedicated to providing products of the highest quality to improve patient outcomes with shortened recovery time and reduced revision rates.”
