I hope yours will not be a permanent disability to shoot two-handed.
, if you mean shooting one handed, it is a skill all shooters should practice regularly. In a tactical situation your support hand may become disabled, or otherwise occupied and one handed shooting is something useful to know.
, if you mean shooting one handed with your usual support hand, ditto the above comment.
To achieve any sort of shooting skill, one or two handed, grip, sight alignment, trigger control and practice, practice, practice
