yes i am sure you can find an orthopedic (hand) surgeon willing to do take a crack at it (no pun intended) but you could be asking for more trouble than it is worth. in order to get a better cosmetic result it will require a re-break and perhaps a pinning of the metacarpal in order to straighten out the bent digit. the orthopedist will tell you the pros and cons and hopefully your insurance company will be agreeable to paying for it.
can a third metacrapal fracture be fixed 5 years later? . i broke the neck of my third metacarpal (middle finger) about 6 years ago. the results are that my middle finger knuckle is less pronounced on my right hand because the bone healed at a slightly downwards angle. the hand has recently started to bother me a bit (arthritis and fixation on the cosmetics of the hand). is it possible to have surgery/ re-break the bone and straighten it out so that further complications do not arise later on in life. i am 24 now and broke this when i was 18.
