1. A threaded implant (“implant”) adapted for pelvic stabilization, comprising:
a monolithic elongate body having a distal end, a proximal end, and a length from the proximal end to the distal end,
the monolithic elongate body including,
a plurality of threaded regions including, in a proximal to distal direction, a proximal multi-lead thread region adjacent the proximal end, a proximal single lead thread region, a central multi-lead thread region, a distal single lead thread region, and a distal multi-lead thread region adjacent the distal end, the plurality of threaded regions including a plurality of threads that are disposed about a shank,
wherein each of the proximal single lead thread region, the central multi-lead thread region, and the distal single lead thread region includes a plurality of thread interruptions, and
wherein at least a portion of each of the proximal multi-lead thread region and the distal multi-lead thread region includes at least one thread that completes at least one revolution about the shank without a thread interruption,
the shank defining an inner lumen and including,
one or more raised support ribs extending along at least a portion of each of the plurality of threaded regions,
one or more recesses extending along at least a portion of each of the plurality of threaded regions, each of the one or more recesses circumferentially adjacent to one of the one or more raised support ribs,
wherein the plurality of thread interruptions in each of the proximal single lead thread region, the central multi-lead thread region, and the distal single lead thread region are disposed at the one or more recesses,
wherein the shank, within at least one of the proximal single lead thread region, or the distal single lead thread region does not comprise an opening that creates radial communication between the inner lumen and an ambient space radially outside of the inner lumen,
a lattice disposed about the one or more support ribs and the one or more recesses in at least a portion of each of the plurality of threaded regions,
wherein a portion of the lattice is disposed in at least one thread interruption in each of the proximal single lead thread region, the central multi-lead thread region, and the distal single lead thread region.
