Reconstruction of Total Hand Degloving Injury with Combined Free and Pedicled Flaps and Ilizarov Minifixator.

Total hand degloving injuries present a significant challenge in treatment, with no consensus yet on the optimal choice of flap for coverage. Functional reconstruction necessitates careful consideration of syndactyly release, particularly after flap coverage. A 64-year-old woman sustained a total hand degloving injury and underwent extensive reconstructive surgery. Initially, a free superficial circumflex iliac perforator flap was applied to the thumb, whereas pedicled groin and superficial inferior epigastric artery flaps were used for the remaining fingers. However, partial necrosis at the edges of the pedicled flaps necessitated the adduction of the fingers, followed by suturing the skin flaps closed. This led to the formation of adduction contractures, requiring careful release and skin flap extension for effective syndactyly release. Subsequently, the innovative use of an Ilizarov minifixator was used for the dual purpose of interdigital widening and elongation of the flap. At the 27-month follow-up, the patient demonstrated significant functional recovery of the hand and fingers, showing the effectiveness of this multifaceted surgical approach. Despite some residual flexion contractures, the patient regained the ability to write and perform pinching motions with the thumb and middle finger, expressing satisfaction with the surgical outcome. In conclusion, for a functional reconstruction of the thumb and fingers, the thumb and other fingers should be covered separately. When the fingers are in adduction and there is insufficient skin stock for syndactyly release, using an external fixator to expand the interdigital spaces before the syndactyly release proved to be effective.
