The purpose of this study is to investigate the natural course of recurrent anterior dislocation of the shoulder without an operative treatment.<BR>The materials for this study were 145 patients with recurrent anterior dislocation of the shoulder who were once reduced a dislocation of the shoulder at our hospital. Questionnaires about the history of an operation, the history of the dislocations, an apprehension of dislocation, sports activities, and other items were sent to them by mail. The answerers without an operative treatment were divided into three groups. Group A (active) consisted of the patients with redislocation for 2 years before the time of this study. Group C (cured) consisted of the patients without redislocation and an apprehension of dislocation and subluxation over 5 years. Group Q (quiescent) consisted of the rest.<BR>Eighty-one patients answered the questionnaires, including 60 patients without an operative treatment. There were 42 males and 18 females. The age at the time of the initial dislocation averaged 21.6years (10 to 59). The time of dislocation averaged 4.9 times (2 to 15). There were 21 patients in group A,7 in group C and 32 in group Q. We could detect significant factors relevant to the natural healing. The factors were a low frequency of dislocations for a year, a high age at the time of follow-up and a long period between the time of an initial dislocation and the time of follow-up.<BR>Seven (12%) of 60 patients who had recurrent anterior dislocation of the shoulder and no operative treatment had no redislocation and an apprehension of dislocation and subluxation over 5 years.
