The major mechanism of approximately 50% of included orthopedic dislocations was traffic accidents, followed by accident falls and the most common recurrent dislocation was of the hip, followed by the elbow.
Another observation of significance is that in those decades in which labral detachments are most frequent and most severe (after the fourth decade) recurrent dislocations are rarely encountered.
On the other hand, judging by our own experience, dislocations of dual-mobility cups reflect a high degree of joint instability and recurrent dislocations will most often ensue.
In the present study, the hip was the second most common site of dislocation but the most common site of recurrent dislocation with a recurrence incidence of 12.7%.
Recurrent dislocations and instabilities are the most common sequelae of primary anterior shoulder dislocation and are seen especially in young and active persons [3, 4].
Although most surgically stabilized shoulders remain stable over time, recurrent dislocations are important complications to take into account.
In addition, compared to patients with secondary infections requiring removals who generally had a very limited ability to flex their hips when compared to the other major subgroups, the most mobile groups were those with primary or recurrent dislocations.
They occur most frequently and exhibit the greatest severity in decades in which recurrent dislocations are seldom encountered.
Acute instability refers to a primary, traumatic episode in which the patella dislocates laterally, while chronic instability denotes recurrent dislocations.
There were no postoperative infections or recurrent dislocations.
