Fig. 2From: Augmented pedicle trajectory applied on the osteoporotic spine with lumbar degenerative disease: mid-term outcomeRadiological images of a representative case with polymethylmethacrylate-augmented pedicle screw treatment. a–f A 67-year-old female with lumbar spinal stenosis in L4/5 and L5/S1 segments. a Preoperative MRI image showed obvious spinal stenosis in L4/5 and L5/S1 segments (white arrow). b Preoperative CT scanning showed no osteophyte in posterior of vertebrae. c–d Postoperative X-ray showed the normal position of pedicle screws and the cement in the vertebrae. e Lateral X-ray at 36 months after fusion surgery showed normal position of pedicle screws. f Lumber CT scanning at 36 months after fusion surgery showed series cancellous bone through L4/5 and L5/S1 intervertebral space (white arrow)Back to article page
