However, poor correction of kyphotic angulation, the risk of cement leakage, and significant exposure to radiation (for the surgeon, the operating room staff, and the patient) remain significant issues. The authors conducted a study to assess the value of robot-assisted IVA (RA-IVA) for thoracolumbar vertebral body fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The authors performed a retrospective, single-center study of patients who had undergone RA-IVA or conventional fluoroscopy-guided IVA (F-IVA) for thoracolumbar vertebral body fractures. Installation and operating times, guidance accuracy, residual local kyphosis, degree of restoration of vertebral body height, incidence of cement leakage, rate of morbidity, length of hospital stay, and radiation-related data were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Data obtained in 30 patients who underwent RA-IVA were compared with those obtained in 30 patients who underwent F-IVA during the same period (the surgical indications were identical, but the surgeons were different). The mean \u00b1 SD installation time in the RA-IVA group (24 \u00b1 7.5 minutes) was significantly shorter (p = 0.005) than that in the F-IVA group (26 \u00b1 8 minutes). The mean operating time for the RA-IVA group (52 \u00b1 11 minutes) was significantly longer (p = 0.026) than that for the F-IVA group (30 \u00b1 11 minutes). All RA-IVAs and F-IVAs were Ravi\u2019s scale grade A (no pedicle breach). The mean degree of residual local kyphosis (4.7\u00b0 \u00b1 3.15\u00b0) and the percentage of vertebral body height restoration (63.6% \u00b1 21.4%) were significantly better after RA-IVA than after F-IVA (8.4\u00b0 \u00b1 5.4\u00b0 and 30% \u00b1 34%, respectively). The incidence of cement leakage was significantly lower in the RA-IVA group (p &lt; 0.05). The mean length of hospital stay after surgery was 3.2 days for both groups. No surgery-related complications occurred in either group. With RA-IVA, the mean radiation exposure was 438 \u00b1 147 mGy \u00d7 cm for the patient and 30 \u00b1 17 mGy for the surgeon.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>RA-IVA provided better vertebral body fracture correction than the conventional F-IVA.
