ObjectiveTo investigate the clinical efficacy of proximal radioulnar joint fixation with Kirschner wire for treating adult Monteggia fracture. MethodsSixty-two cases of adult with Monteggia fracture were selected as the objects, and were divided into study group (n=31) and control group (n=31) using random number table. The control group received conventional surgical treatment, and the study group received proximal radioulnar joint fixation using Kirschner wire. The clinical efficacy, operative duration, intraoperative blood loss, duration for fracture healing and complications, and so on, were observed in both groups. ResultsThe operative duration was longer, but the duration for fracture healing was shorter in the study group compared to the control group（P＜0.05）.There was no significant difference in the intraoperative blood loss between the two group（P＞0.05）. The scores of pain, function, range of flexion and extension, muscle force, flexion/extension and rotation, and the total score in both groups were significantly higher after operation compared to the scores before operation (P＜0.05), and the increase amplitude of the study group was higher than that of the control group（P＜0.05）. The clinical prognosis and imaging prognosis of the study group were superior to those of the control group（P＜0.05）.The incident rates of poor caput radii malreduction or redislocation, angulation deformity of fracture, delayed union or nonunion of fracture, and dysfunction were significantly lower in the study group compared to the control group (P＜0.05). ConclusionProximal radioulnar joint fixation with Kirschnercan wire obtains a remarkable clinical efficacy for adult Monteggia fracture. But individual plan should be adopted clinically on the basis of fracture condition.
