This approach allows direct visualization of the posterior column and the retroacetabular surface. The dorsocranial articular acetabulum is also accessible either through the fracture gap or after a capsulotomy.
The trochanter osteotomy (digastric slide) can be used to extend the exposure of the Kocher-Langenbeck approach superiorly and anteriorly. This can be done in either the prone or lateral position.
Modified Stoppa approach
This approach to the anterior intrapelvic region allows visualization of:
This approach provides exposure of the inner aspect of the innominate bone from the SI joint to the pubic symphysis.
Extended iliofemoral approach
The extended iliofemoral approach exposes the entire lateral innominate bone, by posterior reflection of the abductors, and reflection of short external rotators.
