ABSTRACT
Posterior cruciate ligament (PCL) avulsion fractures are rare among the pediatric population. Reported PCL injury incidence varies from 1 to 40% depending on the study population. PCL lesions can be isolated or associated with other ligamentous lesions, which makes their management challenging. Knee ligament reconstruction is essential to restore knee stability and, thus, prevent future menisci and cartilage degeneration. However, surgical management of these injuries can lead to subsequent iatrogenic growth disturbances. Case presentation: The authors describe the case of a 13-year-old child involved in a sports accident causing a PCL avulsion fracture associated with an epiphyseal fracture of the proximal fibula resulting from an incomplete peel-off injury of the lateral collateral ligament. The patient was scheduled for open reduction and internal fixation on the same day of the presentation. A long-leg cast was then applied for 6 weeks. By 3 months postoperatively, the patient regained full range of motion, and return to sport was possible 6 months after the surgery. Conclusion: In children and adolescents, PCL avulsion fractures are often associated with other occult lesions. Although good functional and clinical outcomes using operative management for these lesions are reported, specific treatment recommendations are lacking in skeletally immature patients.
ABSTRACT
AIM: To determine the demographic, clinical, biological and bacteriological profile of acute community acquired hematogenous osteomyelitis (AHO) in children. METHODS: Prospective study including children admitted for AHO. We noted the demographic parameters of patients and the clinical, biological and radiological characteristics of the infection. Blood cultures and local specimen in operated children were systematically performed. RESULTS: 70 patients were included. The mean age was 7.7 years. The mean time between onset of symptoms and admission was 3.2 days. Distal tibia was the most frequent localization (18.66%). Fever higher than 38° on admission was found in 92.8% of patients. Creactive protein (CRP) was superior to 20 mg / L in 95.8% and ESR superior to 20 mm in the first hour in 92% of cases. A deep venous thrombosis was found in 7 patients and a pleuropulmonary Staphylococcus infection in 4 patients. A micro organism was isolated in 64.7% of cases. Staphylococcus aureus methicillin susceptible (SAMS) was the predominant germ. Staphylococcus aureus methicillin resistant (SAMR) accounted for 15.7% of staphylococcus aureus infections. The importance of CRP on admission and time to resolution of fever after the start of treatment were significantly higher in SAMR infections. The existence of deep venous thrombosis and a pleuropulmonary Staphylococcus infection and the need for surgical drainage were significantly more frequent in SAMR infections. CONCLUSION: The existence of a severe form of AHO should lead to a high suspicion of SAMR infection and prompt the prescription of an appropriate antibiotiotherapy.
