The present invention relates to a pin guide for operating on avascular necrosis of the femoral head which can completely remove a necrotic portion of an extended region by radially forming side pin guide holes around the center of a central pin guide hole at a front side of a guide body such that the side pin guide holes form a predetermined angle with the central pin guide hole and forming the side pin guide holes such that the latter communicate with the central pin guide hole at the rear side of the guide body. According to the present invention the pin guide for operating on avascular necrosis of the femoral head is characterized by comprising: a guide body a central pin guide hole passing through the center of the guide body and side pin guide holes which are radially formed around the center of the central pin guide hole at the front side of the guide body to thereby form an angle with the central pin guide hole and which are punched so as to communicate with the central pin guide hole at the rear side of the guide body.
