Multitrack and multianchor point screw technique combined with the Wiltse approach for lesion debridement for lumbar tuberculosis

Figure 1 A typical case with bone fusion. A 47-year-old male patient presented with low back pain and left leg numbness and weakness. A and B: The pathological diagnosis was L2/3 lumbar tuberculosis, preoperative lumbar spinal X-ray showed L2/3 intervertebral space collapse; C: Lumbar spinal CT showed L2/3 intervertebral space stenosis and vertebral body destruction, and sequestrum could be seen invading the front of the intervertebral space and protruding backwards into the spinal canal; D: Fat-suppressed magnetic resonance imaging of the lumbar vertebrae showed destruction of the L2/3 intervertebral disc, narrowing of the intervertebral space, pus formation in the intervertebral space protruding towards the front and back of the intervertebral space, and compression of the dural sac; E: C-arm fluoroscopy during the operation confirmed good positioning of the pedicle screws and cortical bone trajectory screws; F and G: X-ray of the lumbar spine 1 year after the operation showed L2/3 intervertebral space fusion, normal positioning of the internal fixation device, and the absence of broken screws and rods; and H: CT scan of the lumbar spine 1 year after the operation showed that the L2/3 vertebral bodies had fused and that tuberculosis lesions had not developed. CT: Computed tomography.
