[1/6] Calcaneus avulsion with a throwback for me personally. Technically Sanders 2, but more apt classification is Beavis (minus Butthead...) This is beavis 2 “beak” fracture, emergency. CT sums up my feelings on the matter. If you miss this, resultant wound carries 29% amp rate.
[2/6] Bone was osteoporotic and I have seen these fall apart when you try to manipulate them percutaneously, tines just go through it. So I made a small lateral incision (green) and gently got the fragment back in place with freer, and then held with clamps.
[3/6] One screw went in fine (from perc superior-posterior incision), but despite being gentle posterior aspect fragmented and was not able to be held. The pieces were pushing outward on skin and I removed them (“cored them out” without releasing soft tissue) to ease pressure.
[4/6] Because I didn’t think 1 screw was enough, I used a lateral hook miniplate to counteract tension forces (red) and get more fixation in fragment. This was casted in slight plantarflexion.

[5/6] Interestingly enough, I didn’t come up with the idea on my own. I saw my mentor do something similar for one of these years ago that had failed initial fixation— and the case made it into The Binder. It’s still there, and I now updated the entry with my own new annotations.
[6/6] If you’re wondering why the construct looks so familiar, turn it sideways... and now it makes more sense. 🙃 Same idea, same screw configuration... biomechanical principles work everywhere! For more on these fractures, read here: https://pubmed.ncbi.nlm.nih.gov/18670282/ 
Addendum: my PA and I texted about this thread, and I’d like to say she deserves much of the credit. It really was a beautiful splint. 😉
