Abstract
A collapsable reamer assembly and method of reaming a cavity into a bone are described. The reamer assembly comprises a base having a housing and an underside presented toward a surface of the bone in use. A collapsable reamer is rotatably mounted in the housing for rotation about a reaming axis directed away from the underside of the base. The collapsable reamer comprises at least one reaming component, supported for movement along the reaming axis from a collapsed state of the reamer to an extended state of the reamer to ream at least partially along the axis into the bone.

A reamer assembly for reaming a cavity substantially along an axis into a bone, the reamer comprising:
- a base having a housing and an underside presented toward a surface of the bone in use;
- and
- a collapsable reamer rotatably mounted in the housing for rotation about a reaming axis directed away from the underside of the base, the collapsable reamer comprising at least one reaming component, supported for movement along the reaming axis from a collapsed state of the reamer to an extended state of the reamer to ream at least partially along the axis into the bone.
A method of reaming a cavity substantially along an axis into a bone using a reamer assembly having a base with a housing and a collapsable reamer rotatably mounted in the housing for rotation about a reaming axis directed away from the base, the collapsable reamer being extensible along the reaming axis from a collapsed state of the reamer to an extended state of the reamer, the method comprising:
- locating the reamer assembly on a surface of the bone with the reaming axis in registration with the axis;
- imparting rotational drive to the collapsable reamer;
- and
- reaming a cavity into the bone by extending the collapsable reamer from the collapsed state toward the extended state along the reaming axis.
