The pair of lumbar interbody implants is designed to be pushed laterally in a space between adjacent vertebrae for replacing the disc between these vertebrae. Each implant comprises a first and a second saggital wall and an anterior wall at one end and a posterior wall at the other end. The two implants are asymmetric to each other and are therefore more appropriate for the trans-foraminal lumbar interbody fusion. Preferably a first implant has a first saggital wall with an outer surface that is curved and a second saggital wall that is essentially plane.
