title: Flexor tendon repair in zone 2C.
abstract: A randomized prospective clinical study was carried out in 33 patients (37 fingers) with lacerations of both FDS and FDP tendons in the area covered by the A2 pulley, that is, zone 2C in Tang's subdivision of no man's land. Both lacerated tendons were repaired in 19 fingers and repair of only FDP with regional excision of FDS were performed in 18 fingers. Follow-up of average 12 months revealed that there was no significant difference in the end results evaluated according to the TAM system. The average TAM was 204 degrees in the fingers with suture of FDP only and 187 degrees in those with suture of both tendons. The fingers with suture of both tendons showed a higher rate of re-operation due to adhesions or rupture of repair. This study suggests that it is better to repair only FDP with regional excision of FDS when both tendons are injured in zone 2C.
