[Ring injuries].

At the Clinic for Plastic and Reconstructive Surgery of the Kantonsspital Aarau eight cases of ring avulsion injuries in one woman and seven men have been treated during the period 1979-1981. Depending on the soft tissue damage, the ring injuries can be divided into four categories. Representative cases of each group and the special problems and difficulties in the reconstruction of each case are described. Microsurgical revascularisation has been particularly useful in cases of incomplete ring avulsion amputations.
