Two-stage flexor tendon reconstruction in zone 2 of the hand in children.

Abstract

Two-stage flexor tendon reconstruction (Hunter) is indicated in children with extensive adhesions in zone 2 of the hand, with some reservations concerning the patient's age and cooperation. Nine children (mean age 6.9 years) were treated with the modified Paneva-Holevich technique, which has advantages over the classic Hunter reconstructions. It involves an intrasynovial graft (FDS of the injured finger) that is anatomically stable and morphologically more appropriate compared with free grafts. The size of the silicone rod is precisely assessed in the first stage, the proximal tenorrhaphy has healed by the time the second stage is performed, and donor site morbidity is minimized. After a mean follow-up of 40.1 months, the mean total active motion was 196 degrees, and eight patients achieved a good or excellent result according to the Buck-Gramcko and the revised Strickland scale. Staged flexor tendon reconstruction is technically feasible even in very young children. Results in children are comparable to those achieved in adults.
