Abstract: A hand surgery operating table connectable to a conventional main operating table and consisting of a forearm support that is rotatable in a horizontal plane as well as pivotable about a horizontal axis, further comprising a base plate carrying a hand support; and up to seven flexible and tensionable arms secured at one end to the base plate and carrying finger-fixing thimbles at the other end. The tension of the arms can be adjusted to any desired extent so that they can either maintain their tensioned fixed position or they can be readily displaced therefrom without having to manipulate their tensioning mechanism.
