Can generative artificial intelligence pass the orthopaedic board examination?

Background: Resident training programs in the US use the Orthopaedic In-Training Examination (OITE) developed by the American Academy of Orthopaedic Surgeons (AAOS) to assess the current knowledge of their residents and to identify the residents at risk of failing the Amerian Board of Orthopaedic Surgery (ABOS) examination. Optimal strategies for OITE preparation are constantly being explored. There may be a role for Large Language Models (LLMs) in orthopaedic resident education. ChatGPT, an LLM launched in late 2022 has demonstrated the ability to produce accurate, detailed answers, potentially enabling it to aid in medical education and clinical decision-making. The purpose of this study is to evaluate the performance of ChatGPT on Orthopaedic In-Training Examinations using Self-Assessment Exams from the AAOS database and approved literature as a proxy for the Orthopaedic Board Examination. Methods: 301 SAE questions from the AAOS database and associated AAOS literature were input into ChatGPT's interface in a question and multiple-choice format and the answers were then analyzed to determine which answer choice was selected. A new chat was used for every question. All answers were recorded, categorized, and compared to the answer given by the OITE and SAE exams, noting whether the answer was right or wrong. Results: Of the 301 questions asked, ChatGPT was able to correctly answer 183 (60.8%) of them. The subjects with the highest percentage of correct questions were basic science (81%), oncology (72.7%, shoulder and elbow (71.9%), and sports (71.4%). The questions were further subdivided into 3 groups: those about management, diagnosis, or knowledge recall. There were 86 management questions and 47 were correct (54.7%), 45 diagnosis questions with 32 correct (71.7%), and 168 knowledge recall questions with 102 correct (60.7%). Conclusions: ChatGPT has the potential to provide orthopedic educators and trainees with accurate clinical conclusions for the majority of board-style questions, although its reasoning should be carefully analyzed for accuracy and clinical validity. As such, its usefulness in a clinical educational context is currently limited but rapidly evolving. Clinical relevance: ChatGPT can access a multitude of medical data and may help provide accurate answers to clinical questions.

Scoliosis Surgery: A Social Media Analysis of Content, Tone, and Perspective.

INTRODUCTION: The purpose of this study was to analyze posts shared on social media sites, Twitter and Instagram, referencing scoliosis surgery for tone, content, and perspective of the posts. METHODS: Public Twitter and Instagram posts from November 2020 to April 2021 were isolated using the hashtag #ScoliosisSurgery or the words "scoliosis surgery." A total of 5,022 Instagram and 1,414 Twitter posts were collected, of which 500 of each were randomly selected to be analyzed by the authors for the variables previously listed. RESULTS: Of the Instagram posts, 91.8% were associated with an image, and 47.8% were postoperative. 96.9% of the posts had either a positive or neutral tone. 38% delivered a progress update, and 29.9% disseminated education or sought to provide awareness. 48.6% of the posts were from the perspective of the patient. Of the Twitter posts, 60.1% contained only words, and 37.8% were postoperative. 75% of the posts had either a negative or neutral tone. 38.4% described a personal story, and 19.3% provided a progress update. 42.3% of the posts were from the perspective of the patient. CONCLUSION: Patients reported a positive tone on Instagram, displaying their progress updates and demonstrating contentment with scoliosis surgery, and a negative tone on Twitter, showing discontentment toward inadequate access to surgery. Although both platforms were used to distribute information and provide awareness, only a small percentage of posts were from physicians and hospitals, indicating opportunities for surgeons to use social media to connect with patients.

The Effect of Subsidence on Segmental and Global Lordosis at Long-term Follow-up After Anterior Cervical Discectomy and Fusion.

OBJECTIVE: Subsidence following anterior cervical discectomy and fusion (ACDF) may lead to disruptions of cervical alignment and lordosis. The purpose of this study was to evaluate the effect of subsidence on segmental, regional, and global lordosis. METHODS: This was a retrospective cohort study performed between 2016-2021 at a single institution. All measurements were performed using lateral cervical radiographs at the immediate postoperative period and at final follow-up greater than 6 months after surgery. Associations between subsidence and segmental lordosis, total fused lordosis, C2-7 lordosis, and cervical sagittal vertical alignment change were determined using Pearson correlation and multivariate logistic regression analyses. RESULTS: One hundred thirty-one patients and 244 levels were included in the study. There were 41 one-level fusions, 67 two-level fusions, and 23 three-level fusions. The median follow-up time was 366 days (interquartile range, 239-566 days). Segmental subsidence was significantly negatively associated with segmental lordosis change in the Pearson (r = -0.154, p = 0.016) and multivariate analyses (beta = -3.78; 95% confidence interval, -7.15 to -0.42; p = 0.028) but no associations between segmental or total fused subsidence and any other measures of cervical alignment were observed. CONCLUSION: We found that subsidence is associated with segmental lordosis loss 6 months following ACDF. Surgeons should minimize subsidence to prevent long-term clinical symptoms associated with poor cervical alignment.

Impact of plastic surgery medical training on medical students' knowledge, attitudes, preferences, and perceived benefits: Comparative study.

INTRODUCTION: Misconceptions surrounding the discipline of plastic surgery are widespread among not only the public, but medical students and professionals, as well. The purpose of this study was to explore how the inclusion of plastic surgery rotation into the medical curriculum affects medical students' knowledge, attitudes and preferences regarding plastic surgery specialization and referral.   Design and Methods: A descriptive-correlational design was utilized to collect data from 200 medical students in the final two years of education from two separate six-year medical programs in Jordan. Data was collected using self-reported questionnaires regarding knowledge of surgical procedures allocation, attitude towards plastic surgery, preference of specialization, and benefits of plastic surgery to physicians and patients. RESULTS: Analysis showed that medical students of plastic surgery integrate rotation (program A) had a higher average score of correct procedure-allocation (M = 12.57, SD = 3.14), compared to non-integrated plastic survey rotation program (program B) (M = 8.29, SD = 3.05) 8.29. About 83% of students in program A had their knowledge on plastic surgery from direct exposure to a plastic surgeon, compared to 43% of program B, and 24% of students in program A reported that their perception of plastic surgery influenced by media compared to 62% of those in program B. CONCLUSIONS: medical students who have been exposed to plastic surgery education are more confident about procedures of plastic surgery specialty and had more reliable sources of knowledge about plastic surgery than those who were not exposed to plastic surgery rotation.

Total hip arthroplasty for Protrusio Acetabuli in a young adult Osteogenesis Imperfecta features and Marfanoid features: A case report.

Osteogenesis Imperfecta is an inherited disease characterized by easily-broken bones, which manifests as multiple fractures with minimal trauma, joint laxity, sclerosis, blue sclera, and several other manifestations. Protrusio acetabuli is defined as the displacement of the femoral head so that it lies medial to the ischioilial line. In a skeletally mature patient with both Marfan syndrome and PA, an eventual hip arthroplasty is the only method available for correction of the deformity. However, in patients with Osteogenesis Imperfecta and PA, THA remains a controversial treatment. A 14-year-old male patient diagnosed with Osteogenesis Imperfecta Type 1A presented to the orthopedic surgery clinic complaining of groin pain of 1-year duration radiating to the thigh and knee. The patient was found to have radiologic signs of protrusion acetabuli. The patient was started with bisphosphonate and after medical failure, underwent a Total Hip Arthroplasty (THA). In post-operative follow-ups, the patient had relief of pain and was able to walk more comfortably and without a lump. The previously operated hip was examined and showed no signs of infection, dislocation, or fracture. Radiographic studies show no evidence of prosthesis failure or loosening with valgus position of the femoral stem and neutral acetabular angle. Ten years after the primary arthroplasty, the previously operated hip had maintained its stability and had no related complications. Despite the controversy surrounding the treatment of younger patients with hip failure, using total hip arthroplasty, this patient exhibited excellent results, with vast improvement in their symptoms and stability.
