The umbilicus and pelvic incidence to inform surgical incisions for anterior lumbar interbody fusions: A radiographic analysis
The umbilicus' level relative to the lumbar spine significantly varies based on PI magnitude. Patients with lower PIs (low sacral slope) have their umbilicus more commonly located over the distal lumbar spine (L4-5 disc/L5 vertebral body), while high PI patients (high sacral slope) have more superiorly located vertebral levels when referencing the umbilicus. Additional clinical investigations will be beneficial to confirm utility of these findings in guiding location of ALIF incisions.
