Robot-assisted PVP or PKP and postoperative image verification with improved minimally invasive tracer fixation. The Patient was diagnosed with lumbar osteoporotic fracture(L1 and L4): a-b. preoperative anteroposterior and lateral radiographs. c-e. preoperative sagittal and axial CT. f-g. Preoperative sagittal MRI showed abnormal signal of bone marrow edema(L1 and L4). h. The method of improved minimally invasive tracer fixation. i. Robot-assisted guide wire placement. j-k. The position verification of guide wire. l. Bone cement injection under fluoroscopy. m-n. Postoperative image verification. o. Postoperative wound: Minimally invasive wound was marked with arrow(→)
