Abstract

The talus is a important bone because it supports and distributes the body forces above it. Avulslon Fractures of the tibial tubercle prior to epiphyseal closure are uncommon. Fractures that are seen most frequently in adolescents. Watson-Jones classified these injuries into three types. The authors treated three cases of the tuberosity fractures. Two adolescent boys were treated with open reduction and screw fixation and K-wire fixation. One adult man was treated with open reduction and circumferential wire fixation. The Osgood-schlatter disease was diagnosed in two patients. There were small flecks of calcification 3 to 4cm proximal to the tubercle in the two adolescent cases. Functional motion was started within six weaks after operation. No early complications occurred, and no later defermities. such as genu recurvatum as reported by Blount, were detected. All patients returned to normal activity in one year after an operation.
