Does the Autologous Matrix-Induced Chondrogenesis (AMIC®) technique result in positive outcomes for the repair of cartilage lesions in the knee in adolescent patients? Preliminary results at 2,6 years average follow-up.

Chondral and osteochondral lesions of the knee in skeletally immature patients, can result in serious long-term sequelae, such as early knee arthrosis. While there is an abundance of studies concerning chondral repair techniques, there have been relatively few studies that have examined outcomes following cartilage repair in skeletally immature patients. Therefore, we planned to answer the following question: does the AMIC® technique result in positive outcomes for the repair of cartilage lesions in the knee in adolescent patients ? Our hypothesis was that the AMIC® technique improves outcomes for skeletally immature patients with an ICRS stage III or IV osteochondral lesion two year after the surgery.

Pediatric fracture reduction in the emergency department.

Limb fractures are a large part of pediatric trauma activity. Conservative treatment is possible because of children's bone remodeling potential. In case of displaced fractures, when a closed reduction can be done in the emergency room (ER), this avoids general anesthesia, hospitalization and the associated costs.

Surgical Treatment of Subfibular Ossicle in Children: A Retrospective Study of 36 Patients with Functional Instability.

Backgrounds: To evaluate the surgical management of a symptomatic subfibular ossicle after severe ankle sprain with functional instability and pain sequelae in children.

Methods: We analyzed 36 patients complaining of functional instability without laxity, 1 year after an ankle inversion trauma associated with the observation of a subfibular ossicle. We systematically suggested the open excision of the residual ossicles, followed by 6 weeks of immobilization and proprioceptive physiotherapy.

Granulocyte-colony stimulating factor enhances bone fracture healing.

Background: Circulating mesenchymal stem cells contribute to bone repair. Their incorporation in fracture callus is correlated to their bioavailability. In addition, Granulocyte-colony stimulating factor induces the release of vascular and mesenchymal progenitors.

Aluminum and iron can be deposited in the calcified matrix of bone exostoses.

Exostosis (or osteochondroma) is the most common benign bone tumor encountered in children and adults. Exostoses may occur as solitary or multiple tumors (in the autosomal syndromes of hereditary multiple exostoses). Exostoses are composed of cortical and medullary bone covered by an overlying hyaline cartilage cap.
