[CLINICAL EXPERIENCE OF RETROGRADE REPLANTATION FOR AMPUTATED TOE].

OBJECTIVE
To summarize the clinical experience of the retrograde replantation for amputated toe.


METHODS
Between January 2010 and August 2015, 11 cases of amputated toes (15 toes) were treated by the retrograde replantation. All patients were male, with a mean age of 31 years (range, 18-45 years). The causes included cutting injury in 6 cases (9 toes) and crush injury in 5 cases (6 toes). One case had amputated great toe and distal segment of the second toe combined with the third toe nail bed contusion; 1 case had amputated proximal great toe and middle segment of the second and third toes; 1 case had amputated proximal segment of great toe and middle segment of the second toe; 7 cases had amputated distal segment of the great toe; and 1 case had amputated middle segment of the fifth toe. The time from injury to hospital was 1-3 hours (mean, 2 hours).


RESULTS
Thirteen toes survived completely after operation. Toe necrosis occurred in 1 toe; partial dorsal skins necrosis and nail bed necrosis occurred in 1 toe, and was cure after repaired with dorsalis pedis island flap. The rate of success for replantation of amputated toes was 93.33% (14/15). X-ray examination showed fracture healing of all survival toes at 8-12 weeks after operation (mean, 10 weeks); internal fixation was removed. Eleven cases were followed up 3-12 months (mean, 7.5 months). The survival toes had good appearance and toenail. The two point discrimination was 9-12 mm (mean, 10 mm) at last follow-up. The patients could walk and run normally.


CONCLUSIONS
It is an ideal surgical method to use retrograde replantation to treat amputated toe, with the advantages of simple operation and high survival rate.
