[Flexor and extensor tendon injuries in children (primary and secondary repair)].

Primary or secondary flexor tendon repair after laceration in children do not have any technical specificity in comparison with adults. However, tendon ruptures may occur more frequently in case of light postoperative immobilization, especially in young children as little cooperation can be expected in the postoperative period. A closed above elbow cast should therefore be applied for onemonth. Early mobilization program has no significant effect on the final result in young children. However, these observations must be relativized in teenagers who should be rehabilitated such as adults. For extensor tendon injuries, dynamic splintage was found to be unnecessary in children. In cases with total transection in zones I, II or III, it is necessary, especially in children younger than 5 years, to transfix the IP joint in extension with a smooth Kirschner wire during postoperative immobilization period.
