Currently, the rate of injuries caused by occupational accident to cause crushing and soft tissue defects in the hand tend to increase and become significantly more complicated. For this reason, the risk of fingers injuries, especially injures causing finger defects, is very high. Besides, the defects after removing the contracture scar, replantation finger surgery, is not done well, will leave sequelae affecting the function and aesthetics of the hand. Subject and method: The uncontrolled clinical interventional study on a total 34 patients with soft tissue defects of the fingers which underwent plastics surgery to cover them with a dorsal metacarpal artery flap in The Upper Limbs and micro-surgery Department, 108 Central Military Hospital during from January 2018 to March 2024.

The distant result, we monitored 33 flaps, the minimum follow-up time was over 3 months. Results: the flap and the place of receiving the flap were all good in 29/33 patients accounted 87.9%, the result fit 4 patients. Mobility of the finger very good 5/34 patients accounted for 15.1%, good 27/34 patient accounted for 81.8%, not good 1/34 patient accounted for 3%. The size and color of flap is suitable for the receiving area is 32 patients, not suitable is 1 patients.
