An intramedullary implant for use between first and second bone parts, the implant comprising:
- a first threaded end for anchoring to the first bone part;
- and
- a second end extending from the first end for anchoring to the second bone part, the second end having:
- a first anchor arm having a first tooth and a spaced apart second tooth, the first and second teeth extending from the first anchor arm in a first direction, and
- a second anchor arm having a third tooth extending from the second anchor arm in a second direction, the first and second directions being different.

- a first threaded end for anchoring to the first bone part;
- and
- a second end including:
- a first anchor arm having a first tooth and a spaced apart second tooth, the first and second teeth extending from the first anchor arm in a first direction,
- a second anchor arm having a third tooth and a spaced apart fourth tooth, the third and fourth teeth extending from the second anchor arm in a second direction, the first and second directions being different, and
- an opening formed between the first and second anchor arms and adapted to enable elastic deformation of the first and second anchor arms, and
