There is a school of thought that damage that severe results in years, if not a lifetime of pain walking. A major mobility issue that will last forever if the foot is even useful at all.Gonna take more than a Band-Aid to fix that.
After a time, some individuals want the pain and mobility issues gone.
Solution (for some) is amputation.
The current state of prosthetic technology is such that people whose foot could not be reconstructed to the point of full functionality are now able to walk, run, rock climb, and do everything they couldn’t do with the permanently damaged did functional foot.
