Document Type and Number:

WIPO Patent Application WO/2014/196531

Kind Code:

A1

Abstract:

In the present invention, when an extender is removed from a spinal implant, the extender is removed without using a separate apparatus, and the loss of a material to be discarded is reduced. A head part (22) of a spinal implant (2) has the following: a base part (24) provided as a portion of a screw part (21) side; and a pair of tab parts (25) that extend from the base part (24) to the side opposite the screw part (21). The pair of tab parts (25) have formed thereon tab part-side joining parts (31) to which extender-side joining parts join, the extender-side joining parts being formed at extenders which are attached to the pair of tab parts (25) and are for guiding a fixing rod to a slit (23). Between the base part (24) and the pair of tab sections (25), a weak section (26) is formed that breaks due to an external force from the extenders which are joined to the pair of tab parts (25), and that causes the pair of tab parts (25) to separate from the base part (24).
