62. Impaction grafting of the pedicle: a biomechanical analysis

Current options for revising screw failure includes larger diameter revisions and/or injecting cement into the vertebral body for secondary screw fixation. An alternative revision method is impaction grafting (pedicoplasty) of the failed pedicle screw track. This technique utilizes impaction of allograft bone into the pedicle and vertebral body through a series of funnels in an attempt to reconstitute a new pedicle.
