Contouring and applying a pelvic brim plate
Most commonly a pelvic brim plate will be used for the final construct. It will be contoured and applied to the anterior column at this point, though the fixation of the posterior column is performed after subsequent reduction.
The plate must be long enough to provide adequate fixation of both posterior and anterior injuries. This typically requires extension to the pubic body.
The use of a malleable template aids plate contouring.
Because the primary purpose of this plate is to buttress the anterior column, posterior contouring is most critical. For this reason, plate fixation normally starts posteriorly and proceeds anteriorly. Final adjustment of the plate profile can be achieved in situ, due to plate malleability.
Tools for in situ plate contouring include the ball spike for pushing, ...
