A system including an implant having a structure in the form of a plate for compressing together first (O1) and second bone parts separated by a joint, the implant comprising: the plate having a top surface, a bottom bone-contacting surface, and a plurality of holes formed through the top and bottom surfaces, wherein a first hole of the plurality of holes can be positioned on a first side of the joint, and a second hole of the plurality of holes can be positioned on a second side of the joint, the first and second holes being adapted to receive first and second fixation members , respectively, a central axis of the first hole extending into the first bone part (O1) but not the second bone part , and a central axis of the second hole extending into the second bone part but not the first bone part (O1); and a formation made of a rib forming an angled hole (1a1) extending through the plate at an angle between 30° and 60° with respect to the bottom bone-contacting surface, the angled hole (1a1) being formed on a location on a determined portion of a length of the plate and adapted to receive a third fixation member , a central axis of the angled hole (1a1) being angled with respect to a longitudinal axis of the plate, such that when the third fixation member is inserted through the angled hole (1a1), it is arranged to extend into the first bone part (O1), across the joint, and into the second bone part and to compress together the first bone part (O1) and the second bone part in a direction along the longitudinal axis of the plate, characterized in that the system further comprises a template of the plate for use in determining the positioning of the formation against bone, wherein the template does not include any rib. the plate having a top surface, a bottom bone-contacting surface, and a plurality of holes formed through the top and bottom surfaces, wherein a first hole of the plurality of holes can be positioned on a first side of the joint, and a second hole of the plurality of holes can be positioned on a second side of the joint, the first and second holes being adapted to receive first and second fixation members , respectively, a central axis of the first hole extending into the first bone part (O1) but not the second bone part , and a central axis of the second hole extending into the second bone part but not the first bone part (O1); and a formation made of a rib forming an angled hole (1a1) extending through the plate at an angle between 30° and 60° with respect to the bottom bone-contacting surface, the angled hole (1a1) being formed on a location on a determined portion of a length of the plate and adapted to receive a third fixation member , a central axis of the angled hole (1a1) being angled with respect to a longitudinal axis of the plate, such that when the third fixation member is inserted through the angled hole (1a1), it is arranged to extend into the first bone part (O1), across the joint, and into the second bone part and to compress together the first bone part (O1) and the second bone part in a direction along the longitudinal axis of the plate, characterized in that the system further comprises a template of the plate for use in determining the positioning of the formation against bone, wherein the template does not include any rib. <EOS>
