摘要：
An extender is removed from a spinal implant without using a separate device, and the loss of materials to be discarded is reduced. A head part of a spinal implant includes a base part, which is provided as a portion on a screw part side, and a pair of tab parts, which extend from the base part to an opposite side to the screw part side. The pair of tab parts have a tab part-side engagement part to be engaged by an extender-side engagement part that is formed on the extender. A weak part is formed between the base part and the pair of tab parts, the weak part being configured to be broken by an external force from the extender engaged with the pair of tab parts and separate the pair of tab parts from the base part.
