I'll try to keep this short.
- The able-bodied man suffers a permanent weak grip and/or hand weakness because of a hand injury.
- He receives said injury from the fight against unarmed person.
- The fight takes place in an abandoned kitchen - the valuable items were looted so I doubt there will be any knives, folks or steel kitchen utensils laying around.
- He prefers to avoid a hospital if possible. He's wanted by police.
- He has sufficient medical knowledge although he is no doctor nor nurse. He also has good first kit - it's the marine's first kit.
It has to be something he can treat on himself. The complications are fine if it results in weakness. I realize self-treatment is difficult in this situation with his only good hand. He'll have to manage.
I can't find how a hand injury can cause the permanent weak hand/grip. All I could find is the illnesses and diseases, not physical injury. Is it broken bones healed incorrectly? Tendons? Muscles or nerves? All four?
If it is likely to be a human bite, then how hard bite will be? Maim? Chew/Gnaw, etc?
I'm willing to make him go to a hospital if the injury have to be severe, but I want to avoid this scenario. I don't need the treatments or infection knowledge; I'm sure I can handle these.

From my searches: dog bites, human bites, bitten hand injury, causes of hand grip/weakness, permanent hand grip/weakness, hand injury weakness, went through the little details tags (down to 2007, gave up because I can't find anything even close) and few others I can't quite remember. My apologies if I missed something easy.
The sources I find, they often describe the treatments but nothing on if a sufferer will have any aftereffect. They tend to be complete recovery or damage was too severe. I can't seem to find middle.
