Accuracy of intra-articular glenohumeral joint Injection without any guidance through modified nevaiser approach

[Objective]To evaluate the accuracy of glenohumeral joint intra-articular injection without any guidance through modified Nevaiser approach.[Method]Ninety patients were randomly devided into three groups.Each group received injections of constrast medium without any guidance through one of the three approach:anterior,posterior and modified Nevaiser portal.The accuracy of each approach was by the location of constrast medium and the patients' postoperative condition of different approach was compared defermined,and the accuracy of glenohumeral injection through modified Nevaiser approach were evaluated.[Result]Accuracy rates of three approach were as follows:anterior 50%(n=20),posterior 76%(n=25),and modified Nevaiser approach 91.1%(n=45).Of all patients,5(25%)were patients from anterior approach group complained of servere pain(24 h)with VAS ranging from 5-9 points.There was no occurrence of severe complications such as infection or shoulder malfunction.[Conclusion]The technique of glenohumeral joint injection without any guidance through modified Nevaiser approach is highly accurate.No complication was noted.This thechnique be widely used in glenohumeral joint injection.
