Treatment of painful nonunion of the distal phalanx in the finger with bone graft and dorsal reverse adipofascial flap based on an exteriorized pedicle


Müller, Nadja A; Calcagni, Maurizio; Giesen, Thomas (2015). Treatment of painful nonunion of the distal phalanx in the finger with bone graft and dorsal reverse adipofascial flap based on an exteriorized pedicle. Techniques in Hand & Upper Extremity Surgery, 19(3):115-119.

Abstract

Reconstruction of the distal phalanx bone in cases with painful nonunion is a rare and challenging problem. To restore anatomy and to provide a good cover for the bone graft, an intact nailbed is often required due to the proximity of these 2 structures. We present 3 cases of distal phalanx reconstruction performed with a free corticocancellous bone graft from the distal radius and nailbed reconstruction with a homodigital dorsal reverse adipofascial flap based on an exteriorized pedicle that avoids the dissection of the germinal matrix of the nail. All bone grafts consolidated and all flaps survived. All nail plates grew back with no deformity. In this rare but challenging problem, our combined technique appears to be a valid option that enhances the possibility of good bone healing and maximizes the cosmetic result.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
