The emergency repair of distal thumb injuries involves method selection based on differing criteria. Free neurovascular bundle techniques present slightly higher technical requirements and offer distinct advantages. Among these, the free flap donor site located in the cross toe (as seen in 3392.3 cases) provides excellent concealment but necessitates the dissection and anastomosis of blood vessels and nerves, which imposes the highest technical demands. However, this method is optimal for repairing degloving injuries to the distal segment of the thumb, particularly when there's a need to preserve the integrity of the phalangeal joint and extensor and flexor tendons. Covering with a large nail skin flap not only restores the normal appearance and function of the thumb but also offers very realistic results, making it especially suitable for younger patients or those with high cosmetic requirements.
