Decompression and stabilization surgery using custom-made 3D printed cages

Abstract

The paper describes a method for three-dimensional printing of сustom-made interbody cages accounting for biomechanical parameters of the intervertebral disc (anteroposterior size, anterior and posterior disc heights), which provides the implant with unique characteristics. An example of using custom-made cages providing optimal conditions for the formation of interbody bone-metal block due to the extra tight fit of the combined implant is given. It is shown that custom-made cages have a beneficial effect on the spine support recovery time, significantly reduce the surgical injury, and shorten the time of surgery. The manufacturing of each developed implant which has its own form and architecture is not a serial but a piece production not requiring additional registration procedure. The use of custom-made spinal cages allows optimizing the process of surgical treatment and improving short- and medium-term results.
