摘　　要：Objective： To study the anatomic basis of the bipedicled V-Y gastrocnemins myocutaneons flap for repairing the composite Achilles tendon defect. Methods ： The pedicle anatomy of the bi-pedicled V-Y gastrocnemins myocutaneons flap was examined on 30 cadaver specimens. The sliding distances of the flap were measured at different knee flexion degrees. The bi-pedicled V-Y gastrocnemins myocutaneons flap was applied in 12 cases of Achilles tendon defect with simultaneous skin and soft tissue defect. Results： The surai arteries could be classified into four types. After cutting off the gastrocnemins origin with a ＂ Z-shaped＂ incision, the sliding distance of the flap reached （3. 7 ± 0. 5） cm when the knee flexed 0° ,（4.9 ± 0.7） cm when the knee flexed 30°, （ 6. 7 ±0.7 ） cm when the knee flexed 60°and （9.2 ±0.9） cm when the knee flexed 90°. All the defects healed. The patients recovered ambulation with satisfactory knee and ankle function. The follow-up was 4 months -12 years. Conclusions： Different sural artery types should be noticed during the harvest of the bi-pedicled V-Y gastrocnemins myocutaneons flap. With 90° knee flexion, this flap is suitable for one-stage repair of composite Achilles tendon defect within 9.2 cm ± 0.9 cm.
