Stump and phantom pain after amputation are common, but the responsible mechanisms are still
not clarified. It has been suggested that phantom limb pain can be reduced by regional
anaesthesia and in several recent studies, pain was reduced following intrathecal and
intraforaminal blocks. In this study, the investigators want to investigate if spontaneous
and evoked pain in amputees will be relieved by regional nerve blocks involving the damaged
nerves.
