Abstract：Objective To introduce a method of zoneⅠextensor tendon reconstruction on its insertion.Methods Twenty cases of extensor tendon insertion avulsion or rupture patients were included in this study.Among them 12 were males and 8 were females with an average of 32(22-46) years.Seven cases were on the left hand and 13 cases were on the right hand,with 9 on the index finger,8 on the ring finger and 3 on the little finger.Twelve were injured from crush,5 were from cuts and 3 were from falling objects.They were operated 2h-35d(8.7d on average) after injury.They were treated by reconstructing the insertion surgically by Kirschner wire fixed the distal interphalangeal joint,and then transferred part of flexor digitorum profundus piercing to dorsal of the insertion of extensor tendon through bone tunnel of distal phalanx,finally braided suture with distal stump of extensor tendon.Results All the patients were followed up for 6 months to 1 year.No tendon rupture happened again.According to TAM scoring classification,result was excellent in 13 cases,good in 6 cases,and fair in 1 case.Conclusion The method of extensor tendon reconstruction using the section of flexor digitorum profundus piercing to dorsal of the insertion of extensor tendon through bone tunnel can achieve satisfactory outcomes.
