Guide Templates For Percutaneous Inserter System, And Related Instrumentation, Assemblies, And Methods

A surgical system for bone fixation comprises:

• a bone plate for affixation to underlying bone, the bone plate comprising:
• a first plate end and a second plate end opposite each other along a longitudinal plate axis;
• an outer plate surface and an opposed bone-facing plate surface extending substantially parallel to each other between the first and second plate ends;
• a plurality of fixation holes extending from the outer plate surface to the bone-facing plate surface, the plurality of fixation holes arranged in longitudinal series that begins adjacent the first plate end and terminates adjacent the second plate end;
• and
• a twisted plate portion along which the outer and bone-facing plate surfaces have respective twisted geometries about the longitudinal plate axis;
• and
• a template for placement on an outer surface of soft tissue overlaying the bone plate, the template comprising:
• first and second template ends opposite each other along a longitudinal direction;
• a plurality of apertures located between the first and second template ends, wherein the plurality of apertures are configured to orient insertion trajectories of bone screws through the soft tissue and through associated fixation holes in the bone plate,
• wherein at least a subset of the plurality of apertures are sized and positioned such that, when the template overlays the bone plate, at least one of the insertion trajectories intersects:
• an aperture of the subset of apertures, and
• an associated fixation hole extending through the twisted plate portion.
