Ambispective study of fusion and subsidence in degenerated L4–5/L5–S1 discs treated with oblique lumbar interbody fusion/anterior lumbar interbody fusion using 3D-printed titanium open arch cages

Surgeons have many options when selecting an interbody cage for treating a degenerative disc. While surgical technique is fundamental to interbody fusion efficacy and safety, the cage design has been shown to influence these factors since the cage design itself can promote bone growth and reduce the risk of subsidence. The current study reporting fusion and subsidence rates for the open-arch designed cages supports this novel design's efficacy and safety. The results of this study support the efficacy of the open-arch cage design, which has focused on promoting interbody fusion and minimizing subsidence while maintaining implant safety.
