Although some authors reported that in some cases of subcondylar fracture of the mandible, spontaneous repositioning were shown by closed therapy and the others advocated intermaxillary elastic traction by the ipsilateral bite-block and continuous lateral percutaneous compression with the aim of active realignment of fragments. However, we could not know the detailed course of this kind of treatment.<BR>The authors experienced five cases of the condylar neck fracture with displacement but lineation, and treated by the above remedy. The observation and evaluation was made by use of the radiological examination such as Grant-Lantings projection, P-A projection and Orthopantomography.<BR>As a result, some correction of shortened ramal length was shown, but correction of inclination of the condylar fragment was not achieved by these methods. From this experience, the authors concluded that there were limits in these treatments of repositioning of the fragment, and eventually the open operation should be indicated in these cases of the fracture.<BR>In this report, some discussions were made concerning the mechanism, complication of the above treatment in the cases of condylar neck fracture displacement without dislocation.
