Beware of the unpublished abstract! What is the publication rate of abstracts presented at Musculoskeletal Tumor Society meetings, and how does this compare with other orthopaedic and medical meetings? Three hundred thirty-six podium presentations from six annual meetings were identified and their publication was searched at a minimum of 3 years after the event. An effort was made to determine what percent of these abstracts eventually were published in a peer-reviewed journal. It was determined that 137 abstracts were published for a publication rate of 41%. The average time between presentation at the meeting and publication was 21.8 plus or minus 13.5 months. The published articles appeared in 48 peer-reviewed journals. The rate of publication and time until publication was similar to other orthopaedic meetings and to other medical disciplines. Changes to the cohort, title, or authors occurred in approximately (1/3) of the published articles compared with the abstracts. These results suggest that for various reasons the majority of presented material at Musculoskeletal Tumor Society meetings may not survive peer review and may not be scientifically valid.
Objectives
The medial elbow is stabilized during valgus loading by the ulnar collateral ligament, the flexor pronator mass (FPM), and the radial head. Impairment of the FPM can occur as a result of repeated wrist flexion activity. The purpose of this study was to determine the effect of repeated elbow flexion exercise on medial elbow stability.
Methods
Thirty volunteers were included in this study. Ultrasound images of the medial joint space of the nondominant elbow of the participants were collected during a valgus stress test. The images were collected before and immediately after a wrist flexion exercise protocol.
Results
The wrist flexion strength measure decreased (7.5%) after the exercise protocol (t = 3.840; P = .001). The medial elbow width increased between unstressed (mean ± SD, 2.8 ± 0.1 mm) and stressed (3.6 ± 0.1 mm) conditions (P < .001). The stress‐by‐fatigue interaction was significant (P = .048). The medial elbow width increased after fatigue (0.9 ± 0.09 mm) while remaining unchanged in the unstressed condition.
Conclusions
This study found an effect of repeated wrist flexion exercise on decreasing the stability of the medial elbow. Future research needs to explore the mechanisms leading to the decrease in medial elbow stability and to identify the effect of FPM fatigue on the development of medial elbow pain associated with activities.
This study provides evidence that changes in the width of the medial elbow during clinical evaluation of the unimpaired elbow can be detected by ultrasound. Changing the elbow flexion angle did not affect the change in width of the medial elbow during valgus loading.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
