Supermicrosurgical Experience pertaining to Replantation of Tamai Zone 1 Fingertip Amputations

Abstract

AbstractWith the advent of supermicrosurgery, the replantation of very distal finger amputations has become possible. The choice between replantation or flap surgeries in the treatment of Tamai Zone I finger amputations continues to be a matter of debate. This study aims to evaluate replantation results in Tamai Zone 1 finger amputations. The demographic characteristics and clinical results of 39 patients undergoing replantation for a Tamai Zone 1 finger amputation between 2018 and 2021 were retrospectively analyzed. The Cold Intolerance Severity Score (CISS), two-point discrimination test (2-PD) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) were calculated and recorded after a minimum follow-up period of 6 months. The great majority of patients were males (92.3%, n=36) who had suffered the injuries during work accidents (89.7%, n=35). The socioeconomic status of the patients showed a homogeneous distribution. Replant survival was achieved in 69.2% (n=27) of all fingers. The duration of the surgical procedure in patients who underwent vein repair was significantly longer (p<0.001). However, there was no significant relationship between vein repair and survival rate (p=0.348). This study shows that replantation is a surgical intervention that should be given priority in patients with Tamai Zone 1 amputations. In most cases of unsuccessful replantation, secondary recovery results are also acceptable. Future studies with larger case series are needed.
