Twenty eight patients were treated in this series. These ages ranged from fourteen to sixty six.
Fractures are classified according to the Jinnaka system, and abductive type is still more classified three types with the fractures level of fibula. Through the fractures level of fibula, we know the injuries of the tibio-fibular syndesmosis.
All the medial malleolus fractures were fixed by screw, but the lateral malleolus were not fixed except of special cases.
Twenty two of the twenty eight patients had good result, and the other six cases had symptoms. These symptoms were caused of unfit of joint surfaces and instability of the ankle joint.
