Search

Objective: Literature reviews are essential to the scientific process and allow clinician researchers to advance general knowledge. The purpose of this study was to evaluate if the artificial intelligence (AI) programs ChatGPT and Perplexity.AI can perform an orthopedic surgery literature review. Materials and Methods: Five different search topics of varying specificity within orthopedic surgery were chosen for each search arm to investigate. A consolidated list of unique articles for each search topic was recorded for the experimental AI search arms and compared with the results of the control arm of two independent reviewers. Articles in the experimental arms were examined by the two independent reviewers for relevancy and validity. Results: ChatGPT was able to identify a total of 61 unique articles. Four articles were not relevant to the search topic and 51 articles were deemed to be fraudulent, resulting in 6 valid articles. Perplexity.AI was able to identify a total of 43 unique articles. Nineteen were not relevant to the search topic but all articles were able to be verified, resulting in 24 valid articles. The control arm was able to identify 132 articles. Success rates for ChatGPT and Perplexity. AI were 4.6% (6 of 132) and 18.2% (24 of 132), respectively. Conclusion: The current iteration of ChatGPT cannot perform a reliable literature review, and Perplexity.AI is only able to perform a limited review of the medical literature. Any utilization of these open AI programs should be done with caution and human quality assurance to promote responsible use and avoid the risk of using fabricated search results.

Background: Little is known about extensor tendon failure following drill injury at the time of volar plate fixation. Our goals were to analyze extensor tendon injury following simulated drill penetration, and change in tendon displacement during cyclic loading following simulated drill penetration injury. Methods: Extensor pollicis longus (EPL) and extensor carpi radialis brevis (ECRB) tendons were harvested from 9 fresh frozen cadaveric arms. Eighteen EPL and 18 ECRB samples were created from harvested tendons. Drill penetration injury was performed in either a continuous or an oscillating mode. Injured tendons were subjected to 1200 cycles at 1- to 15-kg cyclic load at a frequency of 1 Hz, and analyzed for failure at drill sites and change in displacement throughout the testing cycle. Results: Ten EPL samples and 16 ECRB samples completed testing without failure. Tendon type (ECRB, EPL), mode of injury (continuous, oscillating), and location (proximal, distal) did not affect tendon displacement during loading. A single EPL tendon failed following continuous drill penetration injury. Extensor carpi radialis brevis samples had a mean change in displacement of 2.8 (standard deviation [SD]: 1.5 mm) and 5.9 mm (SD: 4.7 mm) for oscillating and continuous modes, respectively. Six EPL samples had a mean change in displacement of 4.7 (SD: 2.7 mm) and 4.3 mm (SD: 1.8 mm) for oscillating and continuous modes, respectively. Conclusions: Complete extensor tendon failure due to drill penetration was rare. Drill mode did not affect the degree of elongation. Increasing cyclic loading of extensor tendons after drill injury caused modest extensor tendon elongation. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to compare patient-reported outcomes measures, complication rates, and return to hospital in a cohort of patients undergoing anatomic total shoulder arthroplasty (aTSA) or reverse total shoulder arthroplasty (rTSA) with at least one functional somatic syndrome (FSS) to a control cohort., Methods: A retrospective review identifying patients who underwent rTSA or aTSA from 2015 to 2022 was performed. Patients with one or more FSS diagnosis (irritable bowel syndrome, chronic headache, chronic low back pain, or fibromyalgia) were compared against a control cohort. Demographic data, comorbidities, operative data, and patient recorded outcomes including Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE), Pain Interference (PI), and Depression (D) were collected. A 1:1 propensity matching to control for age, gender, and body mass index was performed., Results: A total of 54 patients in the FSS cohort and 125 control patients without FSS were included. The FSS cohort had significantly higher rates of depression ( p  < 0.001), anxiety ( p  < 0.001), and postoperative complications (35.2% vs. 14.4%, p  = 0.002). No significant differences in change in PROMIS-UE, -PI, and -D scores or proportion meeting minimal clinically important difference were seen at one year among the propensity-matched cohort., Discussion: Patients with FSS undergoing shoulder arthroplasty had higher rates of complications; however, PROMIS scores were similar between cohorts., Level of Evidence: Level III., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)
