Pelvic & Acetabular Fracture Treatment - Stryker

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.
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
incretion. 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.
