Objective To access the clinical utility of miniature free Flap to repair multi-digit soft tissue defect. Methods From June 2015 to June 2017, 9 cases of soft tissue defect in 26 digits were treated with multiple miniature free flap reconstructions, including 2 digits defect in 3 cases using bilateral fibular flap of the toe, 3 digits defect in 4 cases using bilateral fibular flap of the toe plus uniliateral medial pedal flap and 4 digits in 2 cases using bilateral fibular flap of the toe plus biliateral medial pedal flap. The doner site were directly closed in all cases. Results All flaps survived postoperatively without vascular crisis. Donor and recipient sites healed by first intention. With a mean follow-up of 18 months (ranged 3～24 months), all free flaps appeared to be in good texture, elasticity and aesthetics. According to CMAHS upper extremity scoring system, postoperative hand function were rated excellent in 21 cases, good in 4 cases and poor in 1 case. Static 2 point discrimination was 7.5 mm (ranged 6 mm～9 mm). Conclusion We can achieve a satisfactory long -term aesthetic and functional outcome of multiple digital soft tissue reconstruction using miniature free flap.
