Move the Hohmann retractor medially carefully onto the sacral ala.

Place an additional Hohmann anterior to the SI joint for additional exposure. Take care when placing this anterior retractor as it may injure the superior gluteal artery and nerve as they exit the greater sciatic notch.

With medial retraction of the abdominal wall and contents, exposure is extended anteriorly towards the ASIS. Retract the ASIS along with the sartorius and the external oblique medially to further expose the inner table of the pelvis and pubic root.

The lateral window is also closed in layers reconstructing the fascial layer preserved in the approach. Introduction The Anterior Superior Iliac Spine ASIS osteotomy can be performed through the lateral window of an anterior pelvic approach such as: Anterior intrapelvic approach plus lateral window Ilioinguinal approach This can be used for ORIF of periprosthetic acetabular fractures or revision arthroplasty.

Scar tissue due to previous exposure might obscure typical landmarks. Skin incision An incision is made along the iliac crest. The incision can be extended intraoperatively depending on the necessary exposure. Superficial surgical dissection Divide the subcutaneous tissues in line with the skin incision in order to expose the fascia overlying the external oblique muscle. The external oblique muscle is subperiosteally elevated from the iliac crest.

With a small elevator, the iliac muscles are elevated using the same subperiosteal layer. Deep dissection When elevating the iliacus muscle, bleeding from nutrient vessels can occur and should be stopped with bone wax.
