Luke Medland who can now wear his wedding ring on the right finger after he was given a specially adapted bionic arm. See MASONS story MNHAND; A romantic husband who was born without a left hand has had his bionic limb customised – so he is always wearing his wedding ring. Luke Medland, 31, was fitted with a carbon fibre Terminator-style mechanical hand – which is controlled by two electrodes on either side of his stump – seven months ago. The new bebionic3 myoelectric(double corr) hand moves like a real human limb by responding muscle twitches in Luke’s lower arm. Incredibly, the robotic arm is so sensitive it means the Luke can stand up on the tube – with the bionic hand gripping the bar and his other holding his bag – for the first time in his life.
