*For date, the first two numbers indicate the month and the last two numbers indicate the year. Pre-operative function was determined from videos taken the day before the earliest surgery.
** Two-tailed p-value from paired Student's t-test
† These patients will have a reduction in apparent supination angle after forearm osteotomy. The mean and p-value represent only those 5 patients with completed reconstructions.
