Osteocutaneous radial forearm free flap: long-term radiographic evaluation of donor site morbidity after prophylactic plating of radius.

摘要

The osteocutaneous radial forearm free flap (ORFFF) is an ideal source of vascularized bone and soft tissue for repair of defects in reconstructions of the head and neck. However, studies have revealed significant donor site morbidity, decreasing the popularity of this procedure. We have previously reported our technique of prophylactic internal fixation of the radius at the time of graft harvest, developed to decrease donor radius fractures. This is a retrospective radiographic review of our long-term radius donor site morbidity. Forearm radiographs more than 3 years after ORFFF with prophylactic plating were evaluated and compared with prior postoperative films. No donor radius fractures were identified. All radiographs exhibited remodeling and/or reconstitution of donor radii. There was no evidence of implant failure, loosening, or surrounding osteopenia. This study lends further credibility to the ORFFF, when prophylactically plated, as a safe and reliable source of vascularized bone and soft tissue for reconstructive procedures.
