PURPOSE: To provide an internal fixation member for infant thighbone ostectomy/cervical fracture treatment by which an operation process is simplified and rotation in an operation can be sufficiently prevented by reliably sticking a blade into an optimal position. CONSTITUTION: An internal fixation member 1 is an infant hip plate forming a blade 2 in an upper part and a shaft plate 3 in a lower part, and in the blade 2, protrusive parts 4 are protrusively arranged on upper and lower surfaces so that a cross section becomes a cross shape. A guide pin inserting guide hole 5 is protrusively arranged in a cross center part, and a blade tip part 2a is formed in a sharp chisel shape. The blade 2 is stuck in the condyle cervical part direction from a diaphysis part upper part of a thighbone along a guide pin set in an optimal position, and the sharp blade tip part 2a can perform an action equal to a chisel.
