We recently had a chance to put into practice some “damage control orthopedics” principles with a complex injury that presented to our trauma center , requiring me to return to my trauma roots and training 🫡
In this example, a young female patient was involved in a high-speed motorcyle accident, sustaining numerous injuries but a complex pelvic fracture and severe perineal trauma / open wounds. EMS appropriately applied a pelvic binder in the field to minimize blood loss, and the injury pelvic x-ray is with the binder on, which can minimize the severity and displacement of the injury. The CT scan better shows the complete instability of the left SI joint / hemipelvis with multiplanar displacement.
At the time of surgery, with the binder removed to allow the gynecology / general surgery team to assess the perineal wounds, the extent of the displacement becomes more evident with a grossly open p***c symphysis and along with the posterior pelvic ring injuries. After initial treatment of the perineal wounds, the decision was made to perform open reduction of the left SI joint as closed reduction attempts were not successful. After stabilizing the right SI joint with a percutaneous iliosacral screw, a lateral window of the ilioinguinal approach was utilized to access the left SI joint. Given the multiplanar instability, multiple reduction aids were utilized, including a Farabeuf clamp along the iliac crest, an angled jaw clamp across the sacral ala, as well as an SI joint plate used as a provisional clamp with screws. An iliosacral screw on the left was then inserted and definitive screws were placed in the SI plate to augment fixation.
After posterior pelvic fixation, there was improved but still significant anterior ring displacement. Given the perineal trauma and open wounds, the decision was made to supplement the fixation with an AIIS-pin external fixator. Patient will require staged procedures to address open wounds - question for colleagues - is this fixation adequate as definitive treatment? Is formal anterior internal fixation mandatory? Convert to in-fix? Lots to consider but patient still has a long road ahead… stay tuned…
