    Application and efficacy of artificial intelligence in patient education on spinal cord injuries

    by Jonas Krueckel, Melanie Ardelt, David Schiffelholz, Josina Straub, Sebastian Siller, Vanessa Hubertus, Sonja Häckel, Denis Bratelj, Christof Wutte, Helena Arias, et al.

    Introduction/background: Spinal cord injuries (SCI) present complex challenges for patients, who increasingly turn to online resources for supplementary information. Large language models (LLMs) like ChatGPT and Google Gemini have emerged as potential tools for patient education. However, concerns about the accuracy, clarity, and comprehensiveness of their responses remain, particularly in specialized fields such as SCI. This study aimed to evaluate the performance of ChatGPT 4, ChatGPT 3.5, and Google Gemini in addressing common patient questions about SCI. Material and methods: A systematic process was used to identify 10 key patient questions related to SCI from online sources, PubMed, and Google Trends. These questions were submitted to ChatGPT 4, ChatGPT 3.5, and Google Gemini using a standardized prompt and a 150-word response cap to elicit expert-like responses. Eight blinded spine surgeons evaluated the chatbot-generated answers for quality, clarity, empathy, and comprehensiveness using a validated rating system. Responses were categorized as “excellent,” “satisfactory with minimal clarification,” “satisfactory with moderate clarification,” or “unsatisfactory.” Results: Across all three models, the majority of responses were rated as either excellent or requiring only minimal clarification. ChatGPT 4 achieved the highest proportion of high-quality responses, with up to almost 90% rated as “excellent” or “minimal clarification required.” ChatGPT 3.5 and Google Gemini performed similarly, with slightly lower percentages of high-quality responses. No statistically significant differences were observed between the models in overall performance. Conclusion: In a standardized single turn, 150-word setting, publicly available LLMs produced largely satisfactory answers to common SCI questions with comparable performance across models. LLMs can be recommended as adjuncts for general patient education, while their outputs should be reviewed within clinical care. Further studies should test multi turn interactions, include patient and multidisciplinary evaluators, compare chatbot responses with clinician authored answers and evaluate the performance of domain specific medical LLMs. Level of evidence: II.

    AO Spine Clinical Practice Recommendations for Adjunctive Medical Therapies in Acute Traumatic Spinal Cord Injury: Contemporary Concepts

    by Chris J Neal, Ricardo Rodrigues-Pinto, Lukas Grassner, Vanessa Hubertus, Farzin Farahbakhsh, Jetan H Badhiwala, David B Anderson, Nader Hejrati, Paul Arnold, Michael G Fehlings, et al.

    Study Design: Review of the literature with critical appraisal and clinical recommendations. Objective: To highlight contemporary concepts involving adjunctive medical and non-surgical therapies in the management of acute traumatic spinal cord injury (tSCI) that may be integrated into clinical practice. Methods: Three recent articles relating to the management of acute tSCI were selected and critically appraised. Clinical practice recommendations were developed and evaluated using the GRADE criteria. Results: Article 1: A Clinical Practice Guideline for the Management of Patients With Acute Spinal Cord Injury: Recommendations on Hemodynamic Management. Conditional recommendation to augment mean arterial blood pressure to at least 75-80 mmHg but not higher than 90-95 mmHg for a duration of 3-7 days to optimize spinal cord perfusion in acute tSCI. Article 2: Spinal Cord Perfusion Pressure Predicts Neurologic Recovery in Acute Spinal Cord Injury. No recommendation can be made at this time in the utilization of SCPP-guided hemodynamic management as an adjunctive strategy in the acute care of tSCI. Article 3: Safety and Efficacy of Riluzole in Acute Spinal Cord Injury Study (RISCIS). No recommendation can currently be made on the routine use of riluzole to patients with acute cervical tSCI. Conclusions: The management of tSCI extends beyond the operating room. The development of emerging medical and non-surgical treatments to augment timely and adequate decompression requires critical consideration as new data becomes available. While some topics do not have the scientific backing to be able to make a recommendation at this time, they point towards areas of future study.

    AO Spine Clinical Practice Recommendations for the Surgical Management of Acute Traumatic Spinal Cord Injury: Contemporary Concepts

    by Vanessa Hubertus, Jetan H. Badhiwala, Nader Hejrati, Aria Nouri, Paula V. Ter Wengel, Farzin Farahbakhsh, Christoph Hofstetter, Chris J. Neal, Mario Ganau, Nitin Agarwal, et al.

    Study Design: Review of the literature with critical appraisal and clinical recommendations. Objective: To highlight contemporary concepts relating to surgical care for acute traumatic spinal cord injury (SCI) based on recent evidence that may be integrated into clinical practice. Methods: Three recent articles relating to the surgical management of acute traumatic SCI were selected and critically appraised. Clinical practice recommendations were developed and graded as strong or conditional. Results: Article 1: Early vs late surgical decompression for central cord syndrome. Strong recommendation to consider early surgery (<24 hours) as an option in patients with ASIA Impairment Scale (AIS) grade C central cord syndrome. Article 2: Extent of decompression in motor complete SCI. Conditional recommendation to consider laminectomy, with or without anterior surgery, to achieve circumferential decompression of the spinal cord. Article 3: Use of intra-operative ultrasound. Conditional recommendation to use ultrasound intra-operatively to confirm the adequacy of surgical decompression. Conclusions: Timely and adequate decompression of the spinal cord are critical priorities in the management of acute traumatic SCI. The importance of timeliness extends to central cord syndrome. Careful consideration and use of operative techniques (e.g., addition of laminectomy) and adjuncts (e.g., intra-operative ultrasound) help achieve safe and adequate decompression of the spinal cord.

  • Identification of a Therapeutic Window for Neurovascular Unit Repair after Experimental Spinal Cord Injury

    by Vanessa Hubertus, Lea Meyer, Lilly Waldmann, Laurens Roolfs, Nima Taheri, Katharina Kersting, Emily von Bronewski, Melina Nieminen-Kelhä, Irina Kremenetskaia, Christian Uhl, et al.

    Traumatic spinal cord injury (SCI) is a devastating condition for which effective neuroregenerative and neuroreparative strategies are lacking. The post-traumatic disruption of the blood–spinal cord barrier (BSCB) as part of the neurovascular unit (NVU) is one major factor in the complex pathophysiology of SCI, which is associated with edema, inflammation, and cell death in the penumbra regions of the spinal cord adjacent to the lesion epicenter. Thus, the preservation of an intact NVU and vascular integrity to facilitate the regenerative capacity following SCI is a desirable therapeutic target. This study aims to identify a therapeutic window of opportunity for NVU repair after SCI by characterizing the timeframe of its post-traumatic disintegration and reintegration with implications for functional spinal cord recovery. Following thoracic clip-compression SCI or sham injury, adult C57BL/6J mice were followed up from one to 28 days. At one, three, seven, 14, and 28 days after SCI/sham, seven-Tesla magnetic resonance imaging (MRI), neurobehavioral analysis (Basso mouse scale, Tally subscore, CatWalk® gait analysis), and following sacrifice immunohistochemistry were performed, assessing vessel permeability via Evans blue (EVB) extravasation, (functional) vessel density, and NVU integrity. Thy1-yellow fluorescent protein+ mice were additionally implanted with a customized spinal window chamber and received longitudinal in vivo two-photon excitation imaging (2PM) with the injection of rhodamine-B-isothiocyanate-dextran for the combined imaging of axons and vasculature up to 14 days after SCI/sham injury. Post-traumatic edema formation as assessed by MRI volumetry peaked at one to three days after injury, while EVB permeability quantification revealed a thoroughly injured BSCB up to 14 days after SCI. Partial regeneration of functional vasculature via endogenous revascularization was detected after one to four weeks, however, with only 50–54% of existing vessels regaining functional perfusion. Longitudinal in vivo 2PM visualized the progressive degeneration of initially preserved spinal cord axons in the peri-traumatic zone after SCI while displaying a rarefication of functionally perfused vessels up to two weeks after injury. Neurobehavioral recovery started after one week but remained impaired over the whole observation period of four weeks after SCI. With this study, a therapeutic window to address the impaired NVU starting from the first days to two weeks after SCI is identified. A number of lines of evidence including in vivo 2PM, assessment of NVU integrity, and neurobehavioral assessments point to the critical nature of targeting the NVU to enhance axonal preservation and regeneration after SCI. Continuous multifactorial therapy applications targeting the integrity of the NVU over the identified therapeutic window of opportunity appears promising to ameliorate functional vessel perseverance and the spinal cord’s regenerative capacity.
