A 49-year-old man presented with low back pain after multiple lumbar spine surgeries. Computed tomography (CT) scan, sagittal cut, showed L2 pars defect. Patient had relief of his back pain for few days after CT-guided local injection of the pars defect. This confirmed that the patient pain generator was the L2 pars defect. The patient was then managed with extension of the instrument fusion to L2.
