Failure of my medical team to get me cutting oranges and limes in pieces

 Oranges need to be cut because peeling oranges one-handed is extremely difficult. Limes need to be cut for gin and tonics.

With zero ability to hold either of these steady in my left hand, I'm forced to try to stab them and them work my way thru, turn around and complete the full cut in the sliced opening. With limes having a much harder skin it takes quite a few tries and picking the limes off the floor as they skitter out from under the point.
