Effectiveness of a large language model for clinical information retrieval regarding shoulder arthroplasty.

Purpose: To determine the scope and accuracy of medical information provided by ChatGPT-4 in response to clinical queries concerning total shoulder arthroplasty (TSA), and to compare these results to those of the Google search engine.

Methods: A patient-replicated query for 'total shoulder replacement' was performed using both Google Web Search (the most frequently used search engine worldwide) and ChatGPT-4. The top 10 frequently asked questions (FAQs), answers, and associated sources were extracted.

Early Catastrophic Failure of Cervical Disc Arthroplasty: A Case Report.

Case: A 47-year-old healthy man underwent cervical disc arthroplasty (CDA) for a C6 radiculopathy. Two-week radiographs showed a well-positioned implant. At the 6-week postoperative visit, the inferior portion of the implant had displaced ventrally, with C6 anterior vertebral body collapse.

COVID-19: Current and future challenges in spine care and education - a worldwide study.

Background: The COVID-19 pandemic has impacted spine care around the globe. Much uncertainty remains regarding the immediate and long-term future of spine care and education in this COVID-19 era.

Study Design: Cross-sectional, international study of spine surgeons.

Discogenic Back Pain: Literature Review of Definition, Diagnosis, and Treatment.

Discogenic back pain is multifactorial; hence, physicians often struggle to identify the underlying source of the pain. As a result, discogenic back pain is often hard to treat-even more so when clinical treatment strategies are of questionable efficacy. Based on a broad literature review, our aim was to define discogenic back pain into a series of more specific and interacting pathologies, and to highlight the need to develop novel approaches and treatment strategies for this challenging and unmet clinical need.

Flexural Rigidity, Taper Angle, and Contact Length Affect Fretting of the Femoral Stem Trunnion in Total Hip Arthroplasty.

Background: Modularity at the head-neck junction in total hip arthroplasty allows for intraoperative adjustments but may be a source of metallic debris. We determined how flexural rigidity, taper angle, contact length, and lever arm affect fretting and corrosion at this junction.

Methods: A total of 77 metal-on-polyethylene total hip arthroplasties retrieved over a 10-year period at a single institution were obtained.

Variations in surgeons' recovery expectations for patients undergoing total joint arthroplasty: a survey of the AAHKS membership.

Recovery expectations (RE) after total hip and knee arthroplasty (THA-TKA) influence outcomes. We surveyed AAHKS members to determine variation in surgeon RE. Four vignettes depicting patients with high and low expectations after THA and TKA were distributed with a validated RE survey.
