@lexfridman @elonmusk @neuralink @elonmusk your insights on the hand are very astute. There are many other subtle insights that have been accumulated by hand surgeons over generations that probably would help with engineering Optimus' hand function. Ask me and it will save you years of work.

@historyinmemes but the Churro Inflation Index is 49%

In lower left corner: "The correct spelling of the word 'monkey' wins the Spelling Bee"

In the other 3 panels, "A animal that is a monkey wins the Spelling Bee"

[MGHHandSurgery @NealChen18]

We asked stable diffusion to draw "Monkey wins spelling bee"

What happened in the lower left hand corner?

An early view of elbow fx dislocations

1. Dislocation + radial head fx
2. MCL/ radial head
3. Coronoid/ radial head
4. Proximal ulna/ radial head

The importance of the balance between the Triangular Ligament and the Transverse Retinacular Ligament, as we learned from Richard Smith, MD. (A, B)

When unbalanced, this may lead to a swan-neck or a boutonniere deformity. (C, D)
