When a non-union does occur, it is usually easily treated with cancellous bone graft from the iliac crest. Resistant and multiply operated atrophic non-unions more frequently occur at the diaphyseal level of long bones. A corticoperiosteal free flap based on the articular branch of the descending genicular artery has previously been described to treat such difficult non-union cases in various sites, but not at the distal radius. At the distal radius metaphysis, the close relationship with the extensor tendons raises concern regarding the ability to fit this free flap to the non-union site without significant interference with tendon function. By careful technique of crumbling the cortex of the flap without tearing the periosteal continuity, the flap can be contoured and snugly fit to this particular site while preserving tendon function. A unique case is presented of a multiply operated resistant atrophic non-union of the distal radius metaphysis in a heavy smoker that was rapidly healed using the genicular corticoperiosteal free flap. | | Language | eng | | Pub Type(s) | Journal Article
