Objective:To explore the possible causes and the treatment of the unefficient internal fixation of Galeazzi fracture.Methods:Twenty-three cases of the unefficient internal fixations of Galeazzi fracture were treated with internal fixations of LC-DCP,autologus spongy bone transplantations.Results:Patients were followed up for 6 to 24 months.All cases had bony union,of which and 20 cases(87%) were obtained satisfactory functional rehabilitations.Conclusion:The major causes that may lead to the unefficient internal fixation of Galeazzi fracture are improper internal fixation,security of internal fixation,and improper early movement.Proper internal fixation,autologus spongy bone transplantation are efftective in the treatment of the unefficient internal fixation of fractures and in the functional rehahililalion of the forearms.
