Via Modern Mechanix, an ad from 1938:
Does this make you think of something other than a medical ad? Maybe it’s the whole thing about the “human hand” being placed on the groin as a truss.
Actually, the best “support” for a “rupture” (a.k.a. an inguinal hernia) these days is some polypropylene mesh sewn into place properly as either a sheet and/or plug to hold the “rupture” in. Back in 1938, the best “support” was some conjoined tendon sewn to the appropriate ligament, the most common of which when I was a resident, back in the days right before mesh became popular, was the Bassini repair, although the Cooper’s ligament repair and Shouldice repair were also taught.
These days, with tension-free repairs done using mesh, hernia repairs are generally not that big a deal. We should be grateful that they are no longer done the way that they were attempted hundreds of years ago:
Now that looks painful.
Clearly, though, surgeons understood even centuries ago the importance of the Trendelenburg position.
