Lauge Hansen SER Supination External Rotation (Eversion) Ankle Fracture

[@epicsdrummer2010]

I agree. Closed kinetic chain supination injuries are associated with an unbalanced inversion moment of force acting across the STJ. Due to the 2 coupled 2 DoF there will be a corresponding unbalanced moment of vertical axial lateral rotation of the proximal tibia. If the angle at the knee joint is small and the condoyles interlocked so accessory rotation is minimal the force will manifest itself in the ankle complex.

I'm glad you enjoyed them.

@hotingneusvoel No problem. I'm glad you found it useful

[@marythatcher3601]

This was the worst pain I have ever felt I was fully willing to to have the paramedics just cut my foot off lol So greatful for their humor and caring. Thank you for the video

[@leannemccarthy8528]

Agreed, i screamed so loud it was heard t2 floors below me....

[@mustangcbr1]

Thank you so much for creating these videos!

[@ejmeshack2218]

What a useful vid, there isn't a simplest way to explain this

[@mynuz1]

she meant to say "external rotation" at 0:18 ... right??

[@DrGlassDPM]

The original cadaver studies, for which the published classification is based on, describe a fixed leg (nailed to the table) and the foot was forcefully rotated externally. Not all fracture patterns follow this action

[@wouterengel1345]

Dr Glass, this is exactly what has been puzzling me: does the "external rotational force on the talus" mean that the leg (lower leg) is rotated internally, i.e. endo rotation? From your remark I would guess so. In an actual trauma situation I would expect the foot to be in a fixed position, with the lower leg rotating internally. Is that right?

@@wouterengel1345 hi do u found ur answer

[@indiscernibleStranger]

@@wouterengel1345 Yes, You are right. It's just Easier to describe both Movements using the foot "external rotation force on the supinated foot"...... In most traumatic situations as you would Imagine the Tibia is the one Internally rotating on the supinated foot, either by HIP JOINT Internally Rotating or KNEE Tibifemoral Joint Internally Rotating. It's logical but You can see how complicated it got.

@BridgeLoungeFL I'lll have to improve that for future projects.

Dr Glass, awesome videos! Clarification!

narrator's voice is annoying and distracting. Otherwise, graphics, mechanism of injury, well done
