Introduction:
The authors report 7 cases of acute tibial tubercle avulsion fractures. The fracture occurred in 6 out of the 7, after an abrupt tension of the patellar tendon in male sporting adolescents (age 13-17 years). Two patients presented symptoms of homolateral Osgood-Schlatter's disease before the lesion.
Method:
According to Ogden's classification, the tibial tubercle avulsion fracture was not displaced in 3 cases (stage IA) and was treated conservatively by immobilization for 6 weeks. In 4 cases, the fracture was displaced and necessitated an internal fixation with plaster for about 6 weeks. A torn patellar tendon was noted in one adolescent having a stage IIIB avulsion fracture.
Result:
The mean follow-up was of 4.5 years (1.5-7.5 years). The results were satisfactory: complete functional recovery, resumption of sport at the previous level and absence of recurvatum.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
