Combined Subdermal Pocket Procedure and Abdominal Flap for Distal Finger Amputations in a Toddler

A girl (aged 1 year and 9 months) sustained traumatic amputation to her middle and ring fingers (zone 1C) by a cup-sealing machine. Full-thickness dorsal skin burn over amputated fingertips was also noted. Emergent finger replantation was performed. Following bone fixation, bilateral digital arteries and nerves were repaired. After complete debridement of the necrotic dorsal skin, the extensor tendon and joint were exposed. Moreover, all dorsal veins were destroyed. The pulps (middle and ring fingers) were de-epithelialized and inserted into the subdermal pocket over her left abdomen. The 2 raised skin flaps were transferred to reconstruct the dorsal skin defects. Division of the replanted finger from abdomen was performed at the 14th postoperative day. The fingers survived completely. Good functional and aesthetic outcomes were achieved.
