Minimally Invasive Robotic Approach to Treating Cement Leakage Into the Psoas: A Case Report.

A 78-year-old woman developed groin and thigh pain, numbness, and hip flexion weakness. Imaging revealed cement leakage from an L4 screw into the psoas, compressing a lumbar plexus branch. Using a spinal robotic system (ExcelsiusGPS, Globus Medical, Inc., Audubon, PA), a minimally invasive approach enabled precise incision planning, safe psoas dissection, and en bloc cement removal. Symptoms resolved immediately. Symptomatic intrapsoas cement leakage causing radiculopathy is rare, and robotic guidance contributed to a safe, accurate procedure.
