The invention provides an intersomatic implant suitable for containing at least one bone graft and for being inserted in the intervertebral space along a predetermined direction. It comprises: a first portion (10) of generally annular shape surrounding an aperture (11) and presenting a top first edge (12) and a bottom first edge (14); and a second portion (16) of elongate shape along its main axis (A) presenting a bottom second edge (18) and a top second edge (20), and interconnecting two facing opposite regions of said first portion (10) along said predetermined direction, thereby dividing said aperture (11) into two housings suitable for containing said bone graft, at least one of said bottom and top second edges projecting from the space defined by said bottom and top first edges (14, 12) of the first portion (10).
