Role of Hashtags in Educating and Promoting the Field of Hand Surgery on Social Media

This study identifies the hand surgery content being posted on Instagram, how hashtags are being used, and those posting to determine what is reaching the public.

Top hand surgery-related hashtags on Instagram from June 2020 to August 2020 were identified by searching "hand surgery" and sorting by relevance. Hashtags were quantified by number and qualitatively assessed. Posts without a clear relationship were excluded. Hashtags relevant to hand surgery were analyzed by educational merit, medical specialty, patient or nonpatient, and demographics.

The top 25 hashtags contained 325,400 posts. The 3 hashtags with the highest number of posts were #carpaltunnel (64,700), #handsurgery (50,500), and #handtherapy (48,300). Most posts were educational (53.2%). Nonsurgical fields (66.5%) posted the most, followed by orthopedic (25.9%), and plastic hand surgeons (7.7%). Nonpatients (68.8%) posted more than patients. The top 3 languages of the posts were English (67.7%), Russian (9.4%), and Spanish (7.1%). However, when looking at the hashtags with more than half of the posts being made by hand surgeons, we observed that most (62.9%) of the posts were noneducational in content.

Instagram posts on hand surgery topics are largely posted by nonexperts and are educational in content. There is a major opportunity for hand surgeons to educate and market effectively using hand surgery-related hashtags. Given the number of hand surgeries performed annually, one would hope to see more representation by hand surgeons on social media. More active participation and provision of educational content by specialists is warranted.

There is an opportunity for hand surgeons to educate those searching upper extremity conditions and seeking out expertise in a domain where information is largely driven by nonsurgeons and the quality of information is not vetted. This study identifies the need for more hand surgeon involvement to expand knowledge and communication efforts within the specialty and with the public through the evolving world of social media.
