What is the usual recovery time for ulnar nerve transposition?

Varies: If all goes well, which is to be expected with today's skilled hand surgeons, most recoveries proceed over about 4 weeks, as if the nerve coverings alone were afflicted, it is likely that repair proceeds in a timely fashion. But if the central axon was damaged, it is a longer process, and indeed, recovery proceeds at the rate of fingernail growth, about 0.1 mm daily.

Variable: It depends on how long you had problem of scarring and symptoms. But you need achieve recovery. If not you need to look for another cause for your ulnar nerve issue.

3-6 months: Depending on how much nerve involvement, 3-6 months.
