Recurrence after primary traumatic anterior dislocation of the shoulder is common. The rate of recurrence is generally thought to be about 20%, and to be related to factors of age, force and situation of injury, length of immobilization complications of primary dislocations, and instability of the shoulder joint. However, a case of recurrence is still a matter of speculation and few reports to be concerned with the rate of recurrence of primary dislocation have yet been in Japan.
About 170 cases were assesed at our University and neighboring hospitals, and the relation between primary dislocation and recurrence were investigated. We studied and examined 104 cases of traumatic dislocation, age, force and situation of injury, length of immobilization, complication of dislocation, and of 66 cases of recurrence, we studied the situation of primary injury and interval of recurrence.
