Abstract
Objective To discuss the surgical indications and methods of replantation of avulsed finger pulp.Methods From 2008 to 2010,43 cases of 45 finger pulp tissue pieces were replanted.The digital artery and volar digital vein were both anastomosed in 23 fingers.In 12 fingers only volar veins were anastomosed for arterialization to perfuse the replants.Converting anastomosed digital artery for venous drainage was done in 6 fingers.The rest 4 fingers did not have anastomosis of the volar veins.Instead venous drainage was achieved by placing a rubber drain in the wound which was dripped with normal saline.Results Replants of 36 fingers survived,accounting for an 80％ survival rate.Of these 36 survivals,25 fingers were follow-up while 11 fingers were lost to follow-up.The follow-up time ranged from 6 months to 3 years.Survival fingers all had good appearances and good functional recovery.Pain,temperature and touch sensation were restored to the replants 3 to 9 months postoperatively (average,6 months).Two-point discrimination of the pulps reached 3 to 7 mm.Conclusion The function and appearance of the replanted finger pulp are good if the replanted avulsed finger pulp tissue survives.Every effort should be made to replant the avulsed piece when the tissue is intact and there is blood vessel for anastomosis. Key words: Finger injuries; Replantation; Finger pulp avulsion
