Atrophic nonunion of the clavicle: treatment by compression plate, lag-screw fixation and bone graft.
We describe a new surgical treatment of atrophic nonunion of the clavicle. The nonunion is excised by cuts at 45 degrees to the long axis and repair uses 3.5 mm pelvic reconstruction or dynamic compression plates, with a lag screw to provide interfragmentary compression. The site is grafted with cancellous bone. We have been successful in all seven patients, with early return to normal function...
متن کاملManagement of clavicle nonunion and malunion.
BACKGROUND Clavicle fractures are common injuries of the shoulder girdle and occasionally result in nonunion or symptomatic malunion. When present, these chronic injuries can result in considerable shoulder dysfunction. A number of surgical techniques have been described for the management of these injuries. Current literature suggests that supplemental bone grafting may not be necessary in all...
متن کاملSingle or double plating for nonunion of the clavicle.
Between January 1982 and January 1999, 684 patients presented with a fracture of the clavicle to the accident and emergency departments of the Tamside and Bury District General Hospitals. Twenty patients (3%) subsequently developed symptomatic nonunion of the clavicle. The original injury resulted from a road traffic accident in 13 patients, from a fall on an outstretched hand in five patients,...
متن کاملExistence of mesenchymal stem cells in sites of atrophic nonunion
OBJECTIVES Nonunion is one of the most troublesome complications to treat in orthopaedics. Former authors believed that atrophic nonunion occurred as a result of lack of mesenchymal stem cells (MSCs). We evaluated the number and viability of MSCs in site of atrophic nonunion compared with those in iliac crest. METHODS We enrolled five patients with neglected atrophic nonunions of long bones c...
متن کاملVascularity in a new model of atrophic nonunion.
Our aim was to develop a clinically relevant model of atrophic nonunion in the rat to test the hypothesis that the vessel density of atrophic nonunion reaches that of normal healing bone, but at a later time-point. Atrophic nonunion is usually attributed to impaired blood supply and is poorly understood. We determined the number of blood vessels at the site of an osteotomy using immunolocalisat...
