I was taught the popliteal artery is a major concern in knee dislocations and as such. Does it rupture frequently?
Yes, it is a concern. No, it doesn't happen very often. It's just a really big deal when it does happen.
And the tibial fractures I’m referring to are the ones with a gross deformity. Hairline fractures, stress fractures aren’t what I was referring to when I said “as in the shin actually snapping.” Have you seen anyone bear weight on a compound tibial fracture?
I've seen more than one person who walked in with a tibial fracture that would require surgery to repair. Tibial plateau fractures, for example.
I can think of at least one who walked in with a transverse fracture of the distal tibia. He was wearing boots that provided at least some degree of splinting, but still walking.
