I cut my hand good myself. They did a Bier Block. It's an air powered double tourniquet and lidocain. Worked real well. Only good for about 30 minuets of surgery. I cut some tendons. They fix them with these Chinese finger cuff thingy. Hand works perfect. I did a lot of circulation therapy with a goose bump ball. DR.was amazed at the healing. Hope your man experiences a quick and full recovery too.
