Abstract

An illustrative technique display and discussions.Review of traditional and new "anatomic" techniques for placement of iliac-spinal fixation.Placement of iliac fixation traditionally has been performed using offset connectors, devascularizing the iliac muscles, in addition to the posterior iliac spine. The technique reviewed provides for the screw heads to be placed in a more anatomic position, allowing rods to be laid parallel without the detachment of the erector spinous muscles.Utilization of anatomic models and discussion of present surgical technique for iliac bolt fixation (traditional) compared and contrasted to newer technique using the anatomic landmarks and structures of the iliac crest.The anatomic models illustrate and support the utilization of an anatomic technique for fixation due to the lessening of muscle trauma, alignment of the rod systems, and preservation of the cortical surfaces.The anatomic placement of iliac bolts provides for improved alignment of constructs while addressing spinal deformities. It may also increase screw pullout and construct strength.
