Variable fixation bone plates

A suprapectineal or infrapectineal bone plate system, comprising:

• bone fasteners including a first fastener and a second fastener;
• and
• a suprapectineal or infrapectineal bone plate comprising:
• a brim segment coupled to a quadrilateral surface (QLS) segment via at least one bridge, wherein the brim segment is configured to be affixed to one of a portion of a pelvic brim or the quadrilateral surface (QLS) below the pelvic brim of a patient, the QLS segment is configured to be arranged directly adjacent to the QLS of the pelvis;
• a plurality of slots arranged on the brim segment, at least a portion of the plurality of slots configured to receive the first fastener to affix the bone plate to the pelvic brim or the quadrilateral surface (QLS) below the pelvic brim, the plurality of slots comprising at least one elongated slot configured to receive the second fastener to non-rigidly affix the bone plate to the pelvic brim or the quadrilateral surface (QLS) below the pelvic brim to facilitate adjustment of the bone plate in a first adjustment direction during an implantation procedure;
• and
• a plurality of slots arranged on the QLS segment including at least one elongated slot arranged on the QLS segment,
• wherein each elongated slot comprises a short dimension with opposing sides that are in contact with the second fastener when the second fastener is arranged within the elongated slot to prevent movement of the bone plate in a short direction, and a long dimension configured to allow linear movement of the bone plate in a second adjustment direction when the bone plate is non-rigidly affixed to the pelvic brim or the quadrilateral surface (QLS) below the pelvic brim, and
• wherein the at least one bridge is malleable and configured to allow pre-operative and/or inter-operative changing of a position of the brim segment relative to the QLS segment.
