The use of subatmospheric pressure dressing for the coverage of radial forearm free flap donor-site exposed tendon complications.

Abstract

Since its description in China in 1978, the radial forearm free flap has become a workhorse for the reconstructive surgeon. However, the flap has known disadvantages in complications of the wrist donor site. Skin graft breakdown with exposure of the flexor tendons of the wrist is the most common. The authors describe in a patient series a new treatment for this complication. They used subatmospheric pressure dressing to stimulate granulation tissue coverage of the tendon and to facilitate epithelialization. As many as one third of all patients undergoing radial forearm free flaps develop exposed tendon complications and may benefit from Vacuum Assisted Closure (VAC) therapy.
