LEVY, Eduardo J.; GARABANO, Germán; ROBADOR, Nicolás  and  SEL, Hernán del. Fractures of the anterior tibial tuberosity in adolescentes with immature skeleton. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2012, vol.77, n.1, pp. 39-44. ISSN 1852-7434.

Background: Fractures of the anterior tibial tuberosity (ATT) account for approximately 3% of all proximal tibial fractures, and occur more frequently in males aged 12 to 17 in the context of sporting activities. Methods: Between 1995 and 2008, 23 ATT fractures were treated in 20 patients. The series was comprised of 18 men and 2 women with an average age of 13.4. Fractures were classified according to the Ogden classification. There were 11 type 1 (5A and 6B); 6 type 2 (3A and 3B) and 5 type 3 (2 subtype A, 3 subtype B). Type 1 and 2A fractures were managed with immobilization, while the remaining required open reduction, internal fixation and immobilization. Results: Bone healing was seen in all patients. 95% returned to their previous sports activity. Hardware caused pain in one patient and one developed a recurvatum. Conclusions: ATT fractures are uncommon. A better understanding of the proximal tibial ossification pattern may lead to a correct diagnosis. It is also important to differentiate it from the Osgood-Schlatter disease, avoiding possible sequelae such as a traumatic patella alta. Considering the Ogden classification we obtained good results with conservative treatment for 1AB and 2A fractures, and open reduction and internal fixation for the 2B and 3AB.
