Patients and methods
We reviewed the clinical records of all patients who had been treated for primary anterior dislocations of the shoulder not associated with fractures of the humerus or scapula at the Emergency Department of our hospital between 1988 and 1992. There were 780 such patients. Of these, 33 (4.2%) were aged 12 years 3 months to 17 years 8 months at the time of the primary dislocation. Radiographs of each of these 33 dislocated shoulders showed a radiolucent line of varying thickness corresponding to
Results
The primary dislocation was traumatic in 21 patients (75%) and atraumatic in 7 patients (25%; Table). Recurrent dislocations occurred in 24 patients (86%), of whom 18 had had traumatic and 6 atraumatic primary dislocations. The number of recurrences ranged from 1 to 30, the average being 6. With respect to the redislocators, 16 patients (67%) had 3 or more recurrences. The mean time lapse between the initial dislocation and the first recurrence was 14 months in those patients who had 1 to 3
Discussion
Of the adolescents in our series, 86% had recurrences of the dislocation and 67% of the redislocators reported 3 or more redislocations. These findings are consistent with the observation that the proportion of patients who redislocate and the number of recurrences are inversely related to age at the time of the primary dislocation.2, 3, 4, 5, 10, 15, 17
Two groups of adolescents with traumatic primary dislocations could be identified in our study: those aged 14 to 17 years at the time of the

2021, JSES InternationalCitation Excerpt :In literature, there is a tremendous amount of information about the causes predisposing to the shoulder and/or elbow trauma in the skeletally immature population. It is ascertained that reasons are mainly attributable to recreational activities and school traumas in patients of early and second childhood, whereas for adolescents, sports injuries and traffic accidents (falls from bicycles or motor vehicles) are the most frequent traumatic mechanisms.1,3–14,17 The lockdown period, characterized by the closure of schools, public parks, and sports clubs and by the prohibition of events that could aggregate people outside the family unit (scouting, religion, music, and various art courses), has substantially eliminated most of the activities at risk for shoulder and elbow injuries.
