“…Previous research has focused on histological examination of growth plate remnants or fibrous tissue in lesions [ 2 , 3 , 6 , 7 ] and revealed the presence of widened physes with sclerotic margins or fibrous tissue without physeal remnants. The differences in histological findings may reflect different disease stages.…”

“…Furthermore, no consensus exists on the pathology of the physis. Pavlov et al reported two areas of reactive new bone formation separated by a dense cellular band of collagenous connective tissue without persistent growth plate elements in the lesion [ 6 ], while Suzuki et al showed a widened growth plate with smooth sclerotic borders and round inferior margins [ 7 ]. These findings led us to perform MRI and histopathological examination to determine whether or not the lesion is occupied by growth plate remnants or fibrous tissue [ 2 , 3 , 6 , 7 ].…”

Background. Elbow overuse injuries are common in adolescent baseball players, but symptomatic persistent olecranon physis is rare, and its pathogenesis remains unclear. Purpose. To examine the histopathological and imaging findings of advanced persistent olecranon physis. Methods. The olecranon physes of 2 baseball pitchers, aged 14 and 15 years, were examined by preoperative magnetic resonance imaging (MRI), and surgical specimens were examined histologically. Results. T2-weighted MRI revealed alterations in the intrachondral signal intensity possibly related to collagen degeneration and increased free water content. Histological findings of specimens stained with hematoxylin-eosin showed complete disorganization of the cartilage structure, hypocellularity, chondrocyte cluster formation, and moderately reduced staining. All these findings are hallmarks of osteoarthritis and are suggestive of cartilage degeneration. Conclusion. Growth plate degeneration was evident in advanced cases of symptomatic persistent olecranon physis. These findings contribute to understanding the pathogenesis of this disease.

“…Several case series and case reports of painful persistent olecranon physes have been described, mostly in overhead athletes such as baseball players, 4,9,13,25,26,30 weight lifters, 38 and tennis players. 32 In our review of the literature, the prevalence of bilateral persistent olecranon physis was not well documented; however, almost all studies that included a contralateral elbow radiograph had complete fusion of the olecranon, as in our patient.…”

“…Delayed union or nonunion of the olecranon apophysis has been described in adolescent throwers and may require surgical fusion. [39][40][41] SUMMARY Elbow injuries have become increasingly common in the pediatric and adolescent athlete. Chronic overuse injuries are more common than acute traumatic fractures and dislocations.…”

Elbow pain and injury in young athletes include both acute traumatic and chronic overuse injuries. The anatomy of the developing pediatric elbow and the rapid growth of youth sports have led to an increase in chronic repetitive stress elbow injuries in the pediatric population. These injuries occur mostly in overhead athletes, throwers, and gymnasts. Force dissipation during throwing or axial loading results in lateral compression elbow injuries such as Panner's disease and osteochondritis dissecans of the capitellum or radial head. Medial distraction forces are responsible for medial injuries such as UCL failure, medial epicondyle apophysitis, and avulsion. Valgus extension overload causes posteromedial elbow impingement, olecranon apophysitis, and olecranon stress fractures. Conservative treatment modalities such as activity modification and physical therapy are successful in most cases, but early recognition is important as delays in diagnosis may prolong symptoms and necessitate operative intervention.
