Successful Triple Flap Procedure for Thumb Reconstruction in Severe Hand Crush Injury.

Abstract

BACKGROUND The thumb is crucial for the aesthetic and functional aspects of the upper extremity. A crushed thumb injury can be particularly challenging, especially for individuals with high demands. Currently, there is no consensus on the best approach for treating a crushed thumb. The scapular flap, vascularized by the subscapular artery system, shows great potential as a free flap option. This report aims to highlight the use of a triple flap procedure to preserve the function of the crushed thumb. CASE REPORT A 47-year-old man had a severe injury to his left hand, resulting in significant soft tissue damage in the thenar region, an amputated thumb, and multiple fractures in the phalanx and metacarpal bones. The case was managed using a combination of scapular, parascapular, and osteo-cutaneous parascapular flaps. The first surgery focused on debridement and preserving viable structures, while the second surgery, performed 3 days later, involved the creation of a triple flap, utilizing the circumflex scapular artery and thoracodorsal artery as skin paddles. The flap remained viable, and 6 months postoperatively, the patient regained significant strength and functionality in his left hand. CONCLUSIONS This case demonstrates that severe hand injuries with thumb amputation require a strategic approach based on wound condition and reconstruction feasibility. Triple flaps can be an effective option for such injuries. This report highlights the challenges of treating severe hand crush injuries and emphasizes the importance of personalized surgical approaches for optimal outcomes.
