Fracturas de la tuberosidad anterior de la tibia en adolescentes con esqueleto inmaduro

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.
