Pelvic fixation device

A pelvic fixation device comprising:

• a first fixation member pair configured to anchor to a pelvic bone on a right side of the medial plane at two points, the first fixation member comprising a first main member and a first interlocking member,
• the first main member having a proximal section comprising a hole therethrough configured to obliquely receive and couple to the first interlocking member and comprising a distal section configured to anchor to the pelvic bone on the right side of the medial plane and
• the first interlocking member comprising a proximal section that is configured to couple to the first main member and comprising a distal section configured to anchor to the pelvic bone on the right side of the medial plane;
• a second fixation member pair configured to anchor to the pelvic bone on a left side of the medial plane, the second fixation member comprising a second main member and a second interlocking member,
• the second main member having a proximal section comprising a hole therethrough configured to obliquely receive and fixedly couple to the second interlocking member and comprising a distal section configured to anchor to the pelvic bone on the left side of the medial plane and
• the second interlocking member comprising a proximal section that fixedly couples to the second main member and comprising a distal section configured to anchor to the pelvic bone on the left side of the medial plane;
• a connecting rod configured to extend between the first and second fixation members and not to infix any bony structure of the pelvis or joint space therein, the connecting rod having two ends configured to fixedly couple with the proximal section of the first fixation member pair at one end of the connecting rod, and the second proximal section of the second fixation member pair at other end of the connecting rod, thereby fixing the relative position between the first main member and the second main member.
