TINAVI robot-assisted one-stage anteroposterior surgery in lateral position for severe thoracolumbar fracture dislocation: A case report

Figure 1 A 16-year-old female with thoracolumbar fracture dislocation of L1 (AO Type C, Load-sharing classification, leukemic stem cell = 8), ASIA B of spinal cord injury. A and B: The pre-operative anteroposterior and lateral radiographs showed thoracolumbar kyphosis with a 26° Cobb’s angle; C: Pre-operative computed tomography scan reconstructions showed L1 fracture dislocation; D: Pre-operative sagittal T2-weighted magnetic resonance image revealed the spinal cord injury.

Figure 3 TINAVI robot-assisted one-stage anteroposterior surgery in lateral position. A: Design the best virtual screw trajectory on 3D image; B: The electric drill is implanted with the guiding pin along the direction of the guiding cannula; C: C-arm fluoroscopy to determine the position of the guiding pin; D: The postoperative anteroposterior and lateral radiographs showed thoracolumbar kyphosis with a 5°Cobb’s angle; E: Postoperative wound.

Figure 4 The anteroposterior and lateral radiographs of 5-mo follow-up showed no loss of corrected Cobb’s angle. A: The pre-operative lateral radiographs showed thoracolumbar kyphosis with a 26° Cobb’s angle; B: The anteroposterior radiographs of 5-mo follow-up; C: The lateral radiographs of 5-mo follow-up showed thoracolumbar kyphosis with a 5.6° Cobb’s angle.
