A system for causing compression between bone elements (1440, 1442, 1444), the system comprising: an apparatus for causing compression between bone elements (1440, 1442, 1444), comprising: an elongated shaft (102, 1402) comprising a longitudinal inner bore; at least one static fixation aperture (108, 1412), at least one compression slot (106, 1406), the at least one compression slot (106, 1406) in communication with the longitudinal inner bore, and the at least one compression slot accepting at least one transverse bolt (226, 228); at least one tensioning cable clearance slot, the at least one tensioning cable clearance slot offset from the at least one compression slot (106, 1406); the system further comprising: a targeting arm (1240, 1460) including multiple apertures which (i) correspond to apertures of the at least one compression slot (106, 1406), and the static fixation apertures, and which, (ii) when the targeting arm is coupled to the apparatus, indicate the proper points at which to drill holes through tissue and/or bone elements to permit insertion of transverse bolts through at least one compression slot and the at least one static fixation aperture, a tensioning cable operatively connected to the at least one transverse bolt (226, 228); and a tensioning device configured to apply a tension to the tensioning cable, and the at least one tensioning cable clearance slot is operable to allow the tensioning cable to bow radially outward from the longitudinal inner bore to avoid interfering with an insertion of the at least one transverse bolt into the at least one compression slot. an apparatus for causing compression between bone elements (1440, 1442, 1444), comprising: an elongated shaft (102, 1402) comprising a longitudinal inner bore; at least one static fixation aperture (108, 1412), at least one compression slot (106, 1406), the at least one compression slot (106, 1406) in communication with the longitudinal inner bore, and the at least one compression slot accepting at least one transverse bolt (226, 228); at least one tensioning cable clearance slot, the at least one tensioning cable clearance slot offset from the at least one compression slot (106, 1406); the system further comprising: a targeting arm (1240, 1460) including multiple apertures which (i) correspond to apertures of the at least one compression slot (106, 1406), and the static fixation apertures, and which, (ii) when the targeting arm is coupled to the apparatus, indicate the proper points at which to drill holes through tissue and/or bone elements to permit insertion of transverse bolts through at least one compression slot and the at least one static fixation aperture, a tensioning cable operatively connected to the at least one transverse bolt (226, 228); and a tensioning device configured to apply a tension to the tensioning cable, and a targeting arm (1240, 1460) including multiple apertures which (i) correspond to apertures of the at least one compression slot (106, 1406), and the static fixation apertures, and which, (ii) when the targeting arm is coupled to the apparatus, indicate the proper points at which to drill holes through tissue and/or bone elements to permit insertion of transverse bolts through at least one compression slot and the at least one static fixation aperture, (i) correspond to apertures of the at least one compression slot (106, 1406), and the static fixation apertures, and which, (ii) when the targeting arm is coupled to the apparatus, indicate the proper points at which to drill holes through tissue and/or bone elements to permit insertion of transverse bolts through at least one compression slot and the at least one static fixation aperture, a tensioning cable operatively connected to the at least one transverse bolt (226, 228); and a tensioning device configured to apply a tension to the tensioning cable, and the at least one tensioning cable clearance slot is operable to allow the tensioning cable to bow radially outward from the longitudinal inner bore to avoid interfering with an insertion of the at least one transverse bolt into the at least one compression slot.
