Abstract:

Objective

To explore the application of digital artery transposition in replantation of fingers with vascular defects and its influence on nerve function and joint function recovery.

Methods

Two hundred patients who underwent replantation of severed fingers at Hengshui People's Hospital from July 2017 to July 2020 were selected and randomly divided into an arterial transposition group and a venous transplantation group according to the random number table method, with 100 cases in each group. The artery transposition group received finger artery transposition, while the vein graft group underwent autologous vein graft bridging. The clinical efficacy, operation time, survival rate of severed fingers, incidence of vascular crisis, functional recovery after replantation of severed fingers, and patient satisfaction were compared between the two groups.

Results

The clinically marked improvement rate (91.00% vs 81.00%) and patient satisfaction (96.00% vs 87.00%) in the arterial transposition group were significantly higher than those in the venous transplantation group (P<0.05). Compared with the venous transplantation group, the operation time in the arterial transposition group [ (45.38±9.47) min vs (58.67±10.25) min ] was shorter, and the survival rate of fingers (95.00% vs 87.00%) was higher (P<0.05). There was no significant difference in the incidence of vascular crisis between the two groups (19.00% vs 24.00%) (P>0.05). The arterial transposition group had shorter two-point discrimination and better sensory function recovery than the venous transplantation group (P<0.05). The activity scores of the metacarpophalangeal joint (MP), proximal interphalangeal joint (PIP), and distal interphalangeal joint (DIP), as well as the activities of daily living in the arterial transposition group were significantly better than those in the venous transplantation group (P<0.05); however, there was no significant difference in the recovery of fingers between the two groups (P>0.05). The blood circulation status and appearance recovery in the arterial transposition group were significantly better than those of the venous transplantation group (P<0.05).

Conclusion

The efficacy and safety of digital artery transposition in replantation of fingers with vascular defects are good, and it can effectively improve the survival rate of fingers and the recovery of neurological function, joint function, and appearance.

Key words: Digital artery transposition, Finger replantation, Vascular defect, Neurological function, Joint function
