Abstract

Introduction: With the dramatic increase in the competitive sports of children and young people, overuse injuries have become more important in the pediatric population. Among these, the most frequent injuries in young athletes are stress fractures. The absence of evident traumatic history and the subtle radiographic changes can cause a diagnostic difficulty and delay the treatment. Fracture of the patella sleeve is a rare fracture only occurs in children. The diagnosis is difficult, both clinically and radiologically. High patella and hemarthrosis are important signs to diagnose this fracture. Presentation of 2 clinical cases of injuries in children and young people in sports: stress fractures and fracture of the patella sleeve. Methods: Retrospective descriptive method with reports of clinical cases based on patients' electronic clinical processes. Results: We present a case of a child, a 13-year-old soccer practitioner who had mentioned well localized pain in the anterior aspect of the right leg with 5 days of evolution and analgesic gait and no history of trauma. The radiographs and CT showed a juxtaposed cortical lesion with apparent contact with the cortical bone without associated periosteal reaction. NMR confirmed stress fracture of the proximal tibial shaft. It was treated conservatively with immobilization with plaster and discharge. We present the case of an 11-year-old boy who suffered a fracture of the patella sleeve. In the imaging study, a fragment of bone with a displacement from the lower pole of the patella was visible. An open fracture reduction was performed. During the surgery confirmed avulsion fracture of a small osteochondral fragment, configuration of a sleeve-like fracture. The amount of cartilage was small, so it was decided to reinsert the 2 anchorages for patellar tendon. After fracture healing and rehabilitation, both returned to sports activity without sequelae or functional limitations. Discussion/Conclusion: A knowledge of the fracture of the patella sleeve, together with its clinical and radiological features, is important to avoid misdiagnosis and treatment delay. Care should be taken not to disturb the proximal tibial process. Although relatively uncommon in the pediatric age, the incidence of fractures described stress have been increasing in this age group. A high degree of suspicion is required to make the diagnosis and avoid too invasive treatment. REFERENCES: Ray JM, Hendrix J.
