I cannot think of a proper noun to describe the physical state of someone who survived an encounter with a bear.
He is walking with a severe limp, and has wounds in his back, and his calf.
Therefore, could his condition be named an infirmity or rather weakness, decrepitude, feebleness? I know that these are mainly used to refer to long time illing people or elders who only stay in bed.
I appreciate any suggestions!
