Figure 4

Lumbar disc MRI and lumbosacral nerve root DTI scan at 90 days post-surgery. (a) is the patient’s MRI sagittal position 90 days post-surgery, the posterior longitudinal ligament is reattached, and the “grape skin” phenomenon has basically disappeared. (b) is the patient’s MRI axial position 90 days post-surgery, showing the spinal canal is well dilated. (c) is the nerve root reconstructed by DTI 90 days post-surgery, and the compressed nerve root microstructure is fully restored, comparable to the uninjured side.
