Treatment of lumbar tuberculosis with minimally invasive anterior lesion clearance combined with posterior fixation

Figure 1  Technical roadmap.

Figure 2 Key stages of combined approach lumbar tuberculosis surgery. A: Oblique surgical positioning; B: Lesion localization under C-arm fluoroscopy; C: Superficial position of the anterior small incision; D: Lesion debridement following exposure of tuberculosis; E: Harvesting an appropriately sized iliac graft; F: Intervertebral fusion following iliac graft implantation.

Figure 3 Imaging progression of lumbar tuberculosis treatment. A: Preoperative computed tomography images showing vertebral bone destruction at T11, L3, and L4; intervertebral space destruction at L3/4; and paravertebral soft tissue swelling; B: Preoperative magnetic resonance imaging showing vertebral bone destruction at L3 and L4 and intervertebral space destruction at L3/4, with associated paravertebral abscess formation; C: Postoperative lumbar X-ray demonstrating intact spinal internal fixation without fracture or displacement, no bone graft migration, and satisfactory intervertebral fusion.
