In this retrospective study, 79 digits of 55 patients received 102 secondary procedures following replantation. We divided the procedures into two groups, occurring before or after 2 months following replantation. The procedures in the early group were mainly for soft tissue coverage (92%), and those in that late group were mainly for tendon (67%) to improve function. Factors associated with higher incidence of early secondary procedures included multiple-finger injury, avulsion or degloving injury and level of injury proximal to zone III in finger replantation (p < 0.05). However, younger patients and those with proximal level replantation in fingers had more late secondary procedures (p < 0.05). Flexor tenolysis procedure significantly improved the digital function after replantation (p < 0.05).
