Abstract
An expansible bone plug assembly comprises a first member closed by a substantially planar surface at one end thereof, the member having a cylindrical outer surface. A central bore extends through the planar surface, and a plurality of longitudinally directed radially extendable fingers form part of the first member. A second member is closed by a hemispherical surface at one end thereof, and has a cylindrical outer surface. A plurality of longitudinally directed radially extendable fingers form part of the second member. The second member fingers are interdigitated with the first member fingers, and bear against the first member and the first member fingers bear against the second member. An axially extensible and retractable compression member extends through the bore and is engaged with the second member for causing the first and second members to be drawn together when the compression member is retracted, so that the fingers of the first and second members are thereby caused to extend radially outwardly.
