Either the metal pinch bolts or the plastic retainer screw came loose. It looks like a replacement to me. What’s the axle spline look like?

There's little good news here. I doubt that is rescuable.
Replacement bottom bracket & crankset would be the order of the day. -
The inner third doesn't have splines from the factory. I'd expect the remaining splines to still engage once tightened.
How much of the axle comes through when fitted?

Don't really know how but I seem to have completely screwed my left crank arm. It looks like the inside splines have all rounded off and I can't get it to fit on properly. Is this just a case of having to replace the whole crank arm (4700)?
