Considerations on 100 cases of free microsurgical flaps in the reconstruction of the soft tissues of the lower limb.

The authors evaluate the results for 100 cases of severe loss of substance of the lower limb treated by microvascular free flaps at the Division of Plastic Surgery, Bellaria Hospital in Bologna, between 1994 and 2001. The cases involved recent traumatic loss of substance in 48 cases, post-traumatic defects such as osteomyelitis, ulcers, unstable scarring, sequelae of burns in 40, and neoplasms in 12. Muscular flaps were used in 89 cases, skin flaps in 9, a flap of the omentum in 1; the latissumus dorsi flap was that most frequently used (50 cases). A total of 87 cases had favorable results, while in 13 cases there was failure of the flap. Based on the results obtained, and experience, current indications and causes of failure are discussed.

Reverse fasciosubcutaneous flap versus distally pedicled sural island flap: two elective methods for distal-third leg reconstruction.

In case of soft-tissue injury to the distal third of the leg, a safe and effective repair technique should be adopted. The use of complex procedures such as free flaps and cross-leg flaps is not always advisable. The authors present two methods that have proved to be both reliable and effective in obtaining long-lasting satisfactory results: the reverse fasciosubcutaneous sural flap and the reverse fasciocutaneous island sural flap. Since 1992 the authors have operated on 25 patients affected by traumatic tissue loss of the distal third of the leg and the calcaneal region. They used the fasciosubcutaneous flap in 14 patients and the sural flap in 11. Both of these flaps are technically simple, safe, and effective, and cause minimal injury to the donor site. The sural flaps are more useful for moderate-size wounds, especially in the calcaneal region, whereas the fasciosubcutaneous flap is better for repairing larger lesions of the leg and the ankle.
