Replantation to treat complex thumb severance / 中华创伤骨科杂志

ABSTRACT

Objective To discuss the methods and effects of replantation to treat complex thumb severance. Methods 56 cases of complex thumb severance combined with soft tissue defects were treated with simple vessel transplantation, veno flap transplantation, dorsal index digital island flap transplantation, digital artery transfer, transfer of radial index digital artery pedicled island flap, or veno arteriolization. The soft defects were repaired by the transfer of extensor index finger tendon and superficial ring finger flexor tendon. Results 50 cases survived and 6 cases failed, with the survival rate being 89%. 42 cases were followed up for 5 to 25 months. The function of the treated thumbs was assessed as excellent in 10, good in 25 and bad in 7. The excellent and good rate was 83%. Conclusion Complex thumb severance can be treated by unconventional replantation so as to achieve good effects.
