Abstract
This study aimed to compare screw placement accuracy and clinical aspects between Augmented Reality Surgical Navigation (ARSN) and free-hand (FH) technique. Twenty patients underwent spine surgery with screw placement using ARSN and were matched retrospectively to a cohort of 20 FH technique cases for comparison. All ARSN and FH cases were performed by the same surgeon. Matching was based on clinical diagnosis and similar proportions of screws placed in the thoracic and lumbosacral vertebrae in both groups. Accuracy of screw placement was assessed on postoperative scans according to the Gertzbein scale and grades 0 and 1 were considered accurate. Procedure time, blood loss and length of hospital stay, were collected as secondary endpoints. A total of 262 and 288 screws were assessed in the ARSN and FH groups, respectively. The share of clinically accurate screws was significantly higher in the ARSN vs FH group (93.9% vs 89.6%, p < 0.05). The proportion of screws placed without a cortical breach was twice as high in the ARSN group compared to the FH group (63.4% vs 30.6%, p < 0.0001). No statistical difference was observed for the secondary endpoints between both groups. This matched-control study demonstrated that ARSN provided higher screw placement accuracy compared to free-hand.

The reviewers found only moderate level evidence showing that computed tomography (CT) guidance has lower breach rates than FH, while screw-related complication rates were conflicting at 0% in CT navigation compared with 0%–1.7% in FH groups[5]
A total of 262 and 288 screws were radiologically assessed in the augmented reality surgical navigation (ARSN) and FH groups, respectively
Summary
This study aimed to compare screw placement accuracy and clinical aspects between Augmented Reality Surgical Navigation (ARSN) and free-hand (FH) technique. No statistical difference was observed for the secondary endpoints between both groups This matched-control study demonstrated that ARSN provided higher screw placement accuracy compared to free-hand. Compared to conventional free-hand (FH) surgical technique, computer-assisted navigation using intraoperative 3D imaging has been shown to improve screw placement accuracy and reduce complications due to screw misplacements[1]. Several studies have compared intraoperative image guidance to free-hand (FH) technique, the evidence in favor of navigation is still limited. In a more recent retrospective study comparing O-arm navigation to FH, Wang et al demonstrated higher pedicle screw accuracy and lower total. ARSN has not yet been directly compared to the conventional FH technique in a clinical setting
