Intramuscular transposition is the least popular decompression method. It yields the lowest rate of excellent results and is associated with the most recurrences with severe ulnar nerve compression.

The main advantage of an intramuscular transposition is that it buries the nerve deeply while providing a tunnel through which the nerve can pass. It also allows the nerve to be entirely surrounded by vascularized muscle tissue. The primary disadvantage is that it is a complicated procedure, involving substantial soft-tissue dissection. The risk of perineural scarring is increased, and the procedure may expose the nerve to repeated muscular contractions.
