Abstract
The case of a 43-year-old male patient is described, who suffered several injuries due to a traffic accident, including a distraction injury to the thoracic spine. A specific feature of this case was the existing spondylodesis with material fracture and secondary loss of reduction. Due to this, the guidewires of the pedicle screws were placed in a navigation pattern in the absence of adjustable pedicles and an abnormal screw corridor. This guarantees an optimal positioning with associated patient safety.

Chandirasegaran S, Chan CYW, Chiu CK, Chung WH, Hasan MS, Kwan MK. Analysis of duration of different stages of surgery in posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) patients: comparison between severe versus non-severe AIS. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024; 33:1683-1690. [PMID: 38294535 DOI: 10.1007/s00586-023-08124-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 12/05/2023] [Accepted: 12/26/2023] [Indexed: 02/01/2024]
Abstract
PURPOSE Prolonged surgical duration in severe adolescent idiopathic scoliosis (AIS) patients is associated with increased blood loss and perioperative complications. The aim of this study was to compare the duration of each stage of posterior spinal fusion (PSF) in severe AIS (Cobb angle ≥ 90°) with non-severe AIS patients. This analysis will identify the most time-consuming stage of PSF and help surgeons formulate strategies to shorten operative time. METHODS Retrospective study whereby 90 AIS patients (Lenke type 2, 3, 4, and 6) who underwent PSF from 2019 to 2023 were recruited. Twenty-five severe AIS patients were categorized in Gp1 and 65 non-severe AIS patients in Gp2. Propensity score matching (PSM) with one-to-one with nearest neighbor matching (match tolerance 0.05) was performed. Outcomes measured via operation duration of each stage of surgery, blood loss, number of screws, fusion levels and screw density. RESULTS Twenty-five patients from each group were matched. Total operative time was significantly higher in Gp1 (168.2 ± 30.8 vs. 133.3 ± 24.0 min, p < 0.001). The lengthiest stage was screw insertion which took 58.5 ± 13.4 min in Gp1 and 44.7 ± 13.7 min in Gp2 (p = 0.001). Screw insertion contributed 39.5% of the overall increased surgical duration in Gp1. Intraoperative blood loss (1022.2 ± 412.5 vs. 714.2 ± 206.7 mL, p = 0.002), number of screws (17.1 ± 1.5 vs. 15.5 ± 1.1, p < 0.001) and fusion level (13.1 ± 0.9 vs. 12.5 ± 1.0, p = 0.026) were significantly higher in Gp1. CONCLUSION Screw insertion was the most time-consuming stage of PSF and was significantly longer in severe AIS. Adjunct technologies such as CT-guided navigation and robotic-assisted navigation should be considered to reduce screw insertion time in severe AIS.

Wang X, Li HX, Zhu QS, Zhu YH. Effectiveness and safety of robot-assisted versus fluoroscopy-assisted pedicle screw implantation in scoliosis surgery: a systematic review and meta-analysis. Neurosurg Rev 2024; 47:108. [PMID: 38456994 DOI: 10.1007/s10143-024-02340-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/10/2024] [Accepted: 03/03/2024] [Indexed: 03/09/2024]
Abstract
This study aimed to assess the effectiveness and safety of robot-assisted versus fluoroscopy-assisted pedicle screw implantation in scoliosis surgery. The study was registered in the PROSPERO (CRD42023471837). Two independent researchers searched PubMed, Web of Science, Cochrane Library, and China National Knowledge Infrastructure. The outcomes included operation time, pedicle screw implantation time, blood loss, number of fluoroscopic, accuracy of pedicle screw position, hospital stays, postoperative hospital stays, Visual Analog Scale (VAS), Japanese Orthopaedic Association (JOA) score, Scoliosis Research Society-22(SRS-22), cobb angle, cobb angle correction rate, sagittal vertical axis (SVA), and complications. Eight papers involving 473 patients met all the criteria. There was no significant difference between the two groups regarding the reduction in operation time. The effect of reducing the pedicle screw implantation time in the RA group was significant (WMD = -1.28; 95% CI: -1.76 to -0.80; P < 0.00001). The effect of reducing the blood loss in the RA group was significant (WMD=-105.57; 95% CI: -206.84 to -4.31; P = 0.04). The effect of reducing the number of fluoroscopic in the RA group was significant (WMD=-5.93; 95% CI: -8.24 to -3.62; P < ). The pedicle screw position of Grade A was significantly more in the RA group according to both the Gertzbein-Robbins scale and the Rampersaud scale. Compared with the FA group, the difference in the hospital stays in the RA group was not statistically significant, but the effect of reducing the postoperative hospital stays in the RA group was significant (WMD = -2.88; 95% CI: -4.13 to -1.63; P < 0.00001). The difference in the VAS, JOA, SRS-22, Cobb angle and Cobb angle correction rate, SVA, and complications between the two groups was not statistically significant. The robot-assisted technique achieved statistically significant results in terms of pedicle screw placement time, blood loss, number of fluoroscopies, accuracy of pedicle screw position, and postoperative hospital stay.

Adolescent Idiopathic Scoliotic Deformity Correction Surgery Assisted by Smart Glasses Can Enhance Correction Outcomes and Accuracy and Also Improve Surgeon Fatigue. World Neurosurg 2023; 178:e96-e103. [PMID: 37423337 DOI: 10.1016/j.wneu.2023.06.144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/29/2023] [Accepted: 06/30/2023] [Indexed: 07/11/2023]
Abstract
OBJECTIVE Augmented reality (AR) is becoming more common and slowly being integrated into the surgical field. With the continuous progression of navigation and visualization techniques, AR has great potential to improve surgical quality and safety. Nevertheless, the effects of AR on surgical outcomes and surgeons' well-being remains poorly studied. The present prospective controlled study aims to assess the effect of surgery assisted with AR smart glasses on adolescent idiopathic scoliosis (AIS) deformity correction outcomes and surgeon fatigue. METHODS AIS patients scheduled for surgical deformity correction were prospectively recruited and assigned to standard or AR-supported surgery, using lightweight AR smart glasses. The demographic and clinical features were recorded. The pre- and postoperative spinal features, operative time, and blood loss were recorded and compared. Finally, the participating surgeons were asked to complete a questionnaire (e.g., visual analog scale for fatigue) to compare the effects of AR on their well-being. RESULTS Our results have shown enhanced spinal deformity corrections with Cobb angle (-35.7° vs. -46.9°), thoracic kyphosis (8.1° vs. 11.6°), and vertebral rotation (-9.3° vs. -13.8°) changes favoring AR-supported surgery. Moreover, AR resulted in significantly lower violation rates per patient (7.5% vs. 6.6%; P = 0.023). Finally, the visual analog scale for fatigue scores consistently showed a significant reduction in fatigue (5.7 ± 1.7 vs. 3.3 ± 1.2; P < 0.001) and other fatigue classifiers for the surgeons after AR-supported surgery. CONCLUSIONS Our controlled study has highlighted the enhanced spinal correction rates in AR-supported surgery and also improved surgeons' well-being and fatigue. These results endorse the adaptation of AR techniques to support AIS surgical correction.
