Twenty patients who had a supracondylar osteotomy of the humerus to correct post-traumatic cubitus varus were reviewed. The mean age of subjects was 9 yaers and 6 months and the mean follow-up period was 5 years and 6 months.The mean carrying angle was -20.5 degrees preoperatively, and -0.2 degrees at follow-up. The correction obtained at surgery was lost in seven; four were lost from the time of operation to that of bony fusion, three were during the skeletal growth.It is thought that the reasons for loss of correction until bony fusion are due to technical factors at surgery, while the loss of correction during skeletal growth may be due to the existence of physeal injuries.The operation should be performed before adolescence, and it is necessary to carefully observe the change in the carryig angle before surgery.
