The records of 19 cases of tardy ulnar halsy have been reviewed more than a year after operation from 1980 to 1985. The average follow-up was 3 years. Those cases with previous precipitating trauma had earlier onset and more frequency of osteoarthrosis of the elbow joint, than those without it. A subcutaneous transposition (S. C. T.) was performed in 11 cases and a submuscular transposition (S. M. T.) in 8 cases. In all cases, preoperative symptoms or findings, more or less, relieved. The both operative methods gave equal results as to the relief of objective findings. However, SMT was preferable to SCT in decreased recurrence rate. Four operative findings, i. e. severe extraneural fibrosis, pseudoneuroma, flat or slender change, and color change of nerve were considered as most frequent and important findings. The presence of severe extraneural fibrosis and flat or slender change of nerve were factors associated with a poor result. The number of the findings also seemed to have relation to eventual result.
