A spinal implant with an elongated shape formed by a plurality of sections (20, 30, 40, 50), the implant having a distal end that is initially inserted into a space between vertebral members and an opposing proximal end, a superior side, an inferior side and lateral sides (18, 19), a longitudinal centerline that extends through the ends (11, 12) and through the plurality of sections (20, 30, 40, 50), the said lateral sides (18, 19) extending along the longitudinal centerline, the implant further comprising: the plurality of sections (20, 30, 40, 50) each having a distal end and a proximal end, each of the sections also having a superior side (121, 131, 141, 151) and an opposing inferior side (122, 132, 142, 152), a first one of the sections including a receptacle bounded within an interior of the first section and having a fixed size and shape, the receptacle having distal, proximal and lateral side walls and being open on the superior and inferior sides (141; 142); and a plurality of hinges that pivotally join together the sections (20, 30, 40, 50) in an end-to-end and articulating arrangement, each of the plurality of hinges connecting together two of the plurality of sections (20, 30, 40, 50), wherein each of the respective two of the plurality of sections (20, 30, 40, 50) has lateral sides that extend between the distal and proximal ends of each section, wherein, when the implant is in a straight configuration, the plurality of hinges are aligned along a plane, and wherein the plurality of hinges extend through the lateral sides of each of the sections between the distal and proximal ends of each section, whereby the plurality of sections (20, 30, 40, 50) are allowed to pivot away from the plane upward in a first direction, and also are allowed to pivot away from the plane downward in an opposing second direction; the receptacle being aligned transverse to and extending across the plane, the receptacle being open in both directions that face away from the plane and wherein a second one of the sections includes another receptacle that is bounded within an interior of the second section and has a fixed size and shape with the receptacle being open on the superior and inferior sides. the plurality of sections (20, 30, 40, 50) each having a distal end and a proximal end, each of the sections also having a superior side (121, 131, 141, 151) and an opposing inferior side (122, 132, 142, 152), a first one of the sections including a receptacle bounded within an interior of the first section and having a fixed size and shape, the receptacle having distal, proximal and lateral side walls and being open on the superior and inferior sides (141; 142); and a plurality of hinges that pivotally join together the sections (20, 30, 40, 50) in an end-to-end and articulating arrangement, each of the plurality of hinges connecting together two of the plurality of sections (20, 30, 40, 50), wherein each of the respective two of the plurality of sections (20, 30, 40, 50) has lateral sides that extend between the distal and proximal ends of each section, wherein, when the implant is in a straight configuration, the plurality of hinges are aligned along a plane, and wherein the plurality of hinges extend through the lateral sides of each of the sections between the distal and proximal ends of each section, whereby the plurality of sections (20, 30, 40, 50) are allowed to pivot away from the plane upward in a first direction, and also are allowed to pivot away from the plane downward in an opposing second direction; the receptacle being aligned transverse to and extending across the plane, the receptacle being open in both directions that face away from the plane and wherein a second one of the sections includes another receptacle that is bounded within an interior of the second section and has a fixed size and shape with the receptacle being open on the superior and inferior sides.
