Long bone reconstruction with vascularized bone grafts.

The vascularized fibula may be used for long bone reconstruction reliably and successfully. Since its description by Taylor, the fibula flap has evolved to solve a myriad of long bone reconstructive dilemmas. The flap is used routinely for non-unions, postoncologic resections, and congenital defects. It provides faster and more reliable union than nonvascularized grafts. When constructed in a double-barrel configuration, it offers the ability to bear weight. The vascularized fibula can be used to maintain growth by virtue of transferring the physis. The vascularized fibula is thus both the workhorse and thoroughbred in long bone construction.

Free fibula transfer in the treatment of difficult distal tibia fractures.

Management of the high-grade open distal tibia fracture remains problematic. The authors reviewed the charts of 14 cases of distal tibia and tibial plafond fractures reconstructed with a free fibula transfer. Six cases involved a plafond defect, and the fibula was used to arthrodese the tibio-talar joint. Seven cases included a skin paddle. Three of the four patients with osteomyelitis cleared their infection. Twelve patients went on to osseous union, and two were ultimately treated with amputation. Patients who went on to union had an average of 1.1 subsequent procedures, began full weightbearing in an average of 5.8 months, and were weightbearing without any assistive devices by an average of 8.5 months. There was no significant correlation between the time to full weightbearing and either the presence of infection or the length of the original defect. In this series, 86 percent success was obtained when a free fibula transfer was used either to bridge a tibial non-union or to promote arthrodesis of the tibio-talar joint.

Experience with the extensor digitorum brevis muscle flap for foot and ankle reconstruction.

Soft tissue defects of the foot and ankle region are difficult to treat, given the lack of local flaps. Some methods available are unreliable, multistaged, have significant donor-site morbidity, or are technically complex, requiring significant training and postoperative equipment or monitoring not available at all institutions. We report the largest experience using the extensor digitorum brevis muscle flap for foot and ankle reconstruction. The charts of 20 patients were retrospectively reviewed. Eighty-five percent of the wounds were successfully treated with this flap, with minimal donor-site morbidity. The extensor digitorum brevis muscle flap has minimal morbidity, is easy to elevate, does not require microsurgical skills, and can be performed at most institutions. The extensor digitorum brevis muscle flap is a practical option for wounds located at the foot and ankle region and should be considered in patients potentially requiring a free flap.
