Possible operations to improve movement /dexterity etc

Jcreek75

Hi ,apologies first of all if this is it wrong **** category or already has been discussed.

When I was 16 I had a tendon transplant which gave me me more pincher movement between my thumb and index finger. I was told by the surgeon at the time at the time (2001) that any further operations were 50/50 on improvement or could make me less dexterous

My question is with the advancements in science, are they are any further operations I could look into and what are people's experiences around the subject

Thanks in advance

Jay
