Introduction: Diagnosis is the key to improving spinal surgical outcomes. Full endoscopic spinal surgery (FESS) can create new indications when the diagnosis of radiculopathy is improved. We assessed the finite element method (FEM) to visualize and digitize lesions not detected by conventional diagnostic imaging.Methods: The lumbar patient was a 67-year-old woman with a history of rheumatoid arthritis, and with osteoporosis and pulmonary fibrosis. She had left L3 radiculopathy due to an L3 vertebral fracture. The cervical patient was a 61-year-old woman with left C6 radiculopathy due to C5-6 disc herniation. We performed full endoscopic foraminotomy on the patient’s request. Based on CT DICOM data of 0.5-mm slices preoperatively and postoperatively, 3D imaging data were reproduced by Mechanical Finder??, and kinetic simulation of FEM was performed.Results: Postoperatively, their radiculopathy disappeared, improving their activities of daily living, and enabling them to walk and work. The total contact area and maximum contact pressure of the nerve tissue decreased to 30%-80% and 33%-67%, respectively, postoperatively.Conclusions: FEM can be a new method for perioperative evaluation and simulation to visualize and digitize the conditions of the lesion causing radiculopathy. FEM that can overcome both time and economic constraints in routine clinical practice is needed.
