Temperature sensing elements (TSE) were placed adjacent to sensible structures in the wrist in order to monitor temperature changes. TSE 1 was used as a reference to detect the temperature of the irrigation fluid at room temperature of 20°C. Seven TSEs were implanted under direct visualization to: radial recess (rr), scapho-lunate ligament (sl), dorsal site and subchondral to the center of the lunate fossa (fl), intra-articularly at the distal radioulnar joint (druj), extra-articular tendon sheath of the 4/5 compartment (4/5), ulnar nerve in alignment to the extra-articular ulno-carpal joint (un), intra-articular at the center of the midcarpal joint (mc).
