important to distinguish between the skeletally
mature and immature population. It has been
shown that because of the growing skeletally
immature patient with open physes, traumatic
shoulder events resulting in a shoulder dislocation
are relatively rare. One of the first studies by
Rowe investigating 500 shoulder dislocations
found that 20% of these dislocations occurred to
patients at the age between 10 and 20 but only
about 2% to patients younger than 10 years [15].
Therefore, these pediatric traumas more often
result in humeral physeal or metaphyseal frac-
tures. In addition the younger patient population
is showing a higher recurrence rate after first-t ime
traumatic shoulder dislocation with a rate up to
100% in patients younger than 10 [15] and
60–94% between 10 and 20 years of age [5, 7,
15]. Children between 14 and 18 years of age are
24 times more likely to experience recurrent
instability compared to infants aged 13 years and
less, with a 14 times more likelihood of recurrent
instability with a closed physis compared with
those with an open physis [12]. There are several
factors reported which may explain the high
recurrence rate in this collective: (1) structural
age-related factors such as a higher composition
of collagen type III fibers in the glenohumeral
