[The flag venous flap in the dorsal finger].

Objective: To improve the design and application of the flag flap.

Method: Based on the anatomical characteristics of the dorsal digital veins and the venous arch, the flag flap pedicled with the veins in the dorsum of the finger was used to repair the skin defects of the ventral finger and hand in six cases.

Results: All flaps survived with primary healing. Three months' follow-up showed that the function and appearance of the finger were satisfactory.

Conclusion: The design of the flap broadens its application in repairing the defects on the ventral finger and hand.
