RESUMO
Extensive forearm bone loss, whatever its etiology, presents a difficult reconstruction problem. This is mainly the case in the presence of lesions of the interosseous membrane associated with the radio-ulnar joint. When preservation of forearm rotation is not possible, cubitalization of the radius and reconstruction of the forearm by creation of a "one bone forearm" seems to be an excellent salvage technique both functionally and cosmetically. Our experience concerns six clinical cases; two of these cases are original and give the authors the opportunity to describe a new reconstructive technique of the distal humerus and elbow by vascularized transfer of the radius onto the radial artery (with a cutaneo-osseous transfer in one case). The etiology of the bone defect included severe trauma in three cases, and a Volkman's syndrome complicated by osteomyelitis in one case. Two cases represent an original technique of reconstruction of the distal humerus by a vascularised transfer of the radius onto the radial artery. Forearm reconstruction is performed by cubitalization of the radius. The etiology was traumatic in one case and neoplastic in another, and a cutaneo-osseous transfer was performed in the latter case. In this difficult problem of bone reconstruction, a favorable functional and cosmetic result was obtained in our series.
