Use of the Keystone Perforator Island Flap in the treatment of chronic lower extremity wounds complicated by osteomyelitis.

INTRODUCTION

Reconstruction of chronic lower extremity wounds can be especially challenging when these wounds are complicated by osteomyelitis. They require the joint expertise of plastic and orthopaedic surgeons.

METHODS

We report our experience using the Keystone Perforator Island Flap following wound and bone debridement as a valuable surgical tool for coverage of complex wounds with bone infection.

RESULTS

Twelve patients underwent similar procedures with overall good outcomes, although two patients experienced a complication, specifically partial flap necrosis and wound dehiscence subsequent to recurrent osteomyelitis. We also reviewed the underlying physiological mechanisms of employing the Keystone flap in order to demonstrate its advantages and efficacy.

CONCLUSION

Our results confirm that the Keystone flap can be a safe, reliable and effective method for coverage of soft tissue defects and the preservation of bone integrity in the management of patients with chronic osteomyelitis.
