3.5 mm Intrapelvic Acetabular System

Michael D Stover, David Stephen, Jorge D Barla, Robin E Peter, Ramesh K Sen

Observed trends in fracture patterns and a shift from non-operative to surgical treatment in pelvic fractures defined a need for new intrapelvic acetabular stabilization devices. Fracture types frequently include associated both column fractures, anterior column posterior hemitransverse, and anterior column variants. While screw fixation alone may not be sufficient in some of these patterns because of bone quality, a plate applied to the quadrilateral surface may be required.

The possibility to deploy such new devices while using less invasive surgical approaches is of significant benefit to more fragile patients. The solution provides a biomechanically sound implant set that can be adjusted intraoperatively to match the patient's anatomy. Further, a new complete set of instruments including plate trials and plateholders, retractors, reduction forceps, benders, and tools for screw insertion provide superior ease of use compared with other available solutions.
