[Results of resection of the head of the ulna].

A follow up of 57 wrists with resection of caput ulnae shows different value to different groups of patients. The painful arthrosis of distal radioulnar joint gives indication in posttraumatic cases. Release of pain and improvement of range of motion will be achieved; loss of strength is the most impairing problem for younger patients. 13 patients out of 21 with posttraumatic deformities were satisfied with the post-operative outcome; 13 patients showed significant loss of strength, too. In case of rheumatoid arthritis with caput-ulnae-syndrome the resection is without alternative, needs to be combined with the arthrodesis of radiolunar-joint, if necessary. 20 of 34 rheumatics were satisfied with the outcome after resection of caput ulnae; in 6 cases an ulnar drift was evident, which implied simultaneous or later partial arthrodesis of the wrist. For all patients release of pain decided on their satisfaction with surgery.
