Clinical application of the technology of supercharging and making flap in Yamano area I type II replantation of broken finger

Abstract

Objective To investigate the clinical efficacy of the use of the technology of supercharging and making flap on Yamano area I type II replantation of broken finger. Methods From January, 2016 to June, 2018, 15 cases (16 fingers) of type II replantation of severed fingers in Yamano area I were treated. During the operation, 2 arteries in the severed fingers were anastomosed and supercharged outside the arteries. Bone fragments in the severed fingers were removed to make them flaps. The blood supply and long-term healing of replanted finger were observed after routine treatment including antiinfection, anticoagulation and antispasm in outpatient follow-up. Results Sixteen fingers of replantation of severed fingers survived smoothly. Followed-up for 6-12 months showed that there were no deformities in the surviving finger, good nail growth, full abdomen and recovery of pain and temperature. The static 2-PD was 7-9 mm. According to the Evaluation Criteria of Replantation Function of Severed Finger of Chinese Medical Association Hand Surgery Society, 13 fingers were excellent and 3 fingers were good. Conclusion In the replantation of Yamano area I type II amputated finger, high survival rate and good healing effect can be achieved by using the technology of supercharging and making flap.
