[Narrow tunnel and compression syndromes of the hand].

In osteofibrous channels of the hand a disproportion of capacity and contents may cause either a restriction of the gliding of the tendon or a lesion of nerves by pressure. During a 5 year period 362 narrow pass and compression syndromes were operated. Trigger fingers were most frequent with 224 cases, followed by 85 de Quervain's diseases, 49 carpal tunnel syndromes and 4 ulnar nerve compression syndromes. These diseases can be operated in a bloodless field and under regional anaesthesia, mostly under outpatient conditions. The manifold reasons of compression syndromes call for differentiated operative procedures.
