Objective: When hands suffer burns, the tendons and digital bones are rarely injured because of the quick withdrawal reflex away from the heat source. Hence, a consensus of opinion regarding the treatment of severe hand burns with osseous blood flow deficiency has not been reached among clinicians. Methods: The patient was a 28-year-old woman whose fingers were accidentally soaked in heated cooking oil (160°C-170°C) for approximately 1 minute. The result was fourth-degree (extending to the tendon) digital burns of the distal end of the proximal interphalangeal joint with blood flow deficiency to the skin, tendon, and bone. Results: We performed immediate reconstructive surgery using an abdominal bipediceled flap. Two weeks later, after the flap was separated, all fingers showed complete range of motion, restoration of the metacarpophalangeal joint, and a high range (0°-75°) of proximal interphalangeal joint mobility with an acceptable digital length. Conclusions: Our experience shows that immediate surgery is highly preferable for deep burns of the hand to avoid delayed intractable complications and to achieve better and faster results.
