Application of lateral lag screw and titanium miniplate in fixing intracapsular sagittal condylar fractures

Objective To evaluate the efficacy of lateral lag screw and mini plate in fixing intracapsular sagittal condylar fractures.Methods 13 cases(16 joints) were reset through the anterior tragus incision approach.Among the 16 joints,five joints were fixed by using two groups of mini plates;eight joints were fixed by using one group mini plate and one lateral lag screw;three joints were fixed by using two lateral lag screws.Curative effects were observed by spiral CT.Results The favorable results were obtained in all cases within six months.All patients were satisfied with the clinical results without any obvious function disturbances.Three cases were of slightly limitation of mouth opening and they were improved by opening exercise,and two cases were of poor malocclusions they were corrected by resilience intermaxillary traction.Conclusion According to the advantages of lateral lag screw and mini plate,the application of lateral lag screw and titanium miniplatecould be an effective treatment in fixing different types of intracapsular sagittal condylar fractures.
