Transinterosseous transfer of a peroneal island flap for reconstruction of prepatellar skin defect: report of two patients.

Abstract

We describe the use of a peroneal vascular transinterosseous island flap for the resurfacing of a prepatellar skin defect in 2 patients. Being a fasciocutaneous flap, the peroneal flap is thin, and the location of perforators is easily and safely detected with a Doppler flowmeter. When used as a vascular island flap, either a distal pedicle or a proximal pedicle can be used. The peroneal flap can be used as either a free flap or a vascularized fibular and fasciocutaneous flap. It may, therefore, be applied to compound skin, subcutaneous tissue, and bone defects in the lower extremities. A peroneal vascular transinterosseous island flap can reach a prepatellar skin defect, whereas the peroneal island flap with conventional proximal pedicle cannot.
