[Techniques of continuous nerve block at the level of the wrist].
Functional treatment without pain is a condition for good results after operations at gliding structures (tendons) or periarticular structures. Good analgesia of the arm and hand is obtained with continuous axillary nerve blocks. Often there is concomitant paralysis and active motion is not possible. We therefore use continuous nerve blocks at the wrist. The technique of these blocks is described in the paper. We use a prefabricated catheter set to introduce the polyethylene catheter and to place it near the nerve as in single shot wrist block. This technique for continuous analgesia of the hand can be used for functional treatment after tenolyses, arthrolyses and stable osteosyntheses of fingers. Median, radial and ulnar nerves can be blocked all at the same time or alone.
