Figure 1 Three types of the included patients. A: Preservation of thumb body involving palmar skin defects of fingernails; B: Preservation of thumb body involving different lengths of fingernails; C: Preservation of thumb body narrow lateral deviation of fingernails.

Figure 2 Surgical procedure of transfer flap. A: The excision of finger and flap was designed and transferred locally; B: The excision of nail flap was designed and transferred locally; C: The excision of composite tissue flap was designed and transferred locally.

Figure 3 Operation process. A: Longitudinal ridge after nail fusion; B: The nail flap was pushed far away to maintain the length of the finger.

Figure 4 The design of the first web space. A: The narrow of the first web space and the thin and small finger were preserved before operation; B: The finger body was reconstructed by flap transfer and the first web space was enlarged.
