Objective To explore the clinical outcomes of three types of multiple flaps from the foot for re-construction of two skin and soft tissue defects in hands. Methods From February, 2003 to September, 2015, 23 cases of hands with two skin and soft tissue defects were treated with 3 types of multiple flaps from the foot. Among of them, 10 cases of adjacent fingers were treated with double foliated pulp flaps from the big toe and the second toe based on a single vascular pedicle of the first dorsal metatarsal vessels; 2 cases of composite tissue defect including finger and hand were treated with double foliated pulp flaps from dorsalis pedis flap and the big toe based on a single vascular pedicle of the dorsalis pedis artery;11 cases of two composite tissue defect in hand were treated with dorsalis pedis flaps based on a single vascular pedicle of the dorsalis pedis artery. The donor site was covered with full-thick-ness skin. All patients were followed-up regularly which included three aspects:appearance, hand function and senso-ry recovery. Results Twenty-three cases of double foliated pulp flaps were survived. Postoperative follow-up time ranged from 3 to 36 months, with an average of 15 months. The postoperative follow-up revealed satisfactory shapes of the multiple flaps and recovery of functions. The sensation was recovered to S 2-S4. The grafting skin in donor site sur-vived completely excluding partial necrosis in 3 cases. The wound were treated by wound dressing, local scar hyper-plasia in donor sites. There was no apparent impairment on the foot function. Conclusion Three types of multiple flaps from the foot based on a single vascular pedicle for reconstruction of two skin and soft tissue defects in hand could achieve good clinical outcomes. The type of flaps can be adapted according to the injury.

Objective: To report the method and clinical effect of reconstruction of proximal thumb plane with iliac bone, combined with the same pedicled toenail and dorsum pedis flaps. Methods: From June 2010 to May 2017, 7 patients with various degrees of proximal thumb defect were treated in the Hand Surgery Department of Ruihua Affiliated Hospital of Soochow University. Among them, there were 3 males and 4 females, aged from 18 to 50 years, with an average age of 29 years. There were 5 cases of proximal thumb defect and 2 cases of distal thumb defect. The thumb reconstruction contained 3 steps: iliac bone graft was used to repair bone defect, toenail skin flap to repair dorsal thumb wound, and dorsum pedis flap to cover volar wound. Full thickness skin graft was used to repair donor site. Results: All the reconstructed fingers survived. The area of toenail skin flap was 3.0 cm×2.5 cm to 5.0 cm×3.0 cm in size. The area of dorsum pedis skin flap was 3.0 cm×3.0 cm to 6.0 cm×3.5 cm in size. The length of iliac bone graft was 2.5-5.0 cm. The follow-up time was 5-28 months, with an average of 10 months. All reconstructed finger pulp was full. The nails grew well. The appearance of fingers was satisfied, and the skin sensation of finger belly was restored to S2 to S3+ . Dorsum finger′s protective sensation of all cases were recovered, and the functions of finger joint were close to normal. The donor area on foot healed well. The scar was not obvious. The walking function was completely normal. Conclusions It is a good method to reconstruct proximal thumb with iliac bone combined with the same pedicled toenail and dorsum pedis flaps without sacrificing toes.
