External Fixation Pelvic Frame Hoffmann II MRI External Fixation System offers rapid application in times of hemodynamic compromise with the ability to access the abdomen and pelvic viscera for secondary procedures. External Fixation is most appropriate for open-book pelvic fractures in which the posterior structures are at least partially intact, or lateral compression injuries with internal rotation of the hemipelvis. Hoffmann II MRI Features ‘Snap-Fit’ connections Single point of tightening Small, lightweight clamps Color–coded components Non-ferromagnetic materials Benefits Rapid frame construction. Fast and easy frame construction. Visualization and access to the fracture site. Quick and easy identification. No frame displacement using MRI. Apex Pins Features Independent, multiplanar pin placement Self-drilling tip 316L Stainless Steel Double helical flute Cylindrical thread design Benefits Stable frame construction. No pre-drilling necessary. MRI Conditional. Excellent pin/bone interface. Great purchase and pull-out resistance 1, 2, 3 . Pubis symphysis dislocation. ExFix stabilization.

Hoffmann II MRI - Pin Placement Techniques The insertion of two K-wires, one on the medial side and one on the lateral side of the iliac wing, provides an accurate targeting method. They identify both borders of the crest and plane of the ilium toward the acetabular roof, helping to ensure safe and correct placement of the Apex pins between the two tables of the ilium. Avoid penetration of the medial cortex in order to limit pelvic viscera risk. Illiac Crest Pin Placement. Illiac Crest and Inferior Illiac spine combined Pin Placement. Due to the supraacetabular bone mass being significantly thicker, a frame construct mounted on a single Apex pin offers improved rigidity. Care has to be taken not to injure the lateral femoral cutaneous nerve during pin insertion. The orientation of the Apex pin can be perpendicular to the body axis or directed somewhat cephalad, depending on the location of the starting point in relation to the greater sciatic notch.
