Bridge Replantation of Segmental Defect of Amputated Digits by Transplantation of Segmental Toe

Objective: To study the replantation method of segmental defect of amputated digits to make the replanted digits more close to the normal digits in length, appearance and function. Methods:Transplantation of segmental toe was applied to accomplish the bridge replantation of amputated digits with segmental loss of proximal interphalangeal joint and circumferential soft tissue and distal normality. Result: Seventeen replanted digits in 15 patients were all survived completely, they were followed up for 7-28 months, with an average of 9 months. Replanted digits had good appearance and sensation static 2 point descrimi-nation (2-PD) of 5 - 15mm. Active motion degrees of interphalangeal joint after exercise in 11 replanted digits obtained from 50 - 70 °in flexion and 0° in extension. Six replanted digits obtained same active motion degrees after tenolysis. Conclusion:Transplantation of segmental toe associated with replantation of amputated digits is an effective procedure in treatment of amputated digits with segmental loss of proximal interphalangeal joint and circumferetial soft tissue defect.
