Bone fastener and methods of use

摘要

A bone fastener includes a proximal member having an inner surface that defines an implant cavity and an outer surface including a first threaded portion configured for penetrating fixation with tissue and a second portion. The proximal member defines a longitudinal axis. An intermediate member includes an inner surface extending between a proximal portion connected with the second portion and a distal portion. A distal member includes an outer surface extending between a proximal portion disposed with the distal portion of the intermediate member and a distal portion configured for penetrating fixation with tissue. The distal member is configured for axial translation relative to the intermediate member. Methods of use are disclosed.

1. A bone fastener comprising:
a proximal member including an inner surface that defines an implant cavity and an outer surface including a first threaded portion configured for penetrating fixation with tissue and a second portion, the proximal member defining a longitudinal axis; an intermediate member including an inner surface extending between a proximal portion connected with the second portion and a distal portion, the proximal portion of the intermediate member including a plate having a first surface configured to engage tissue and a second surface, the plate defining an opening configured for disposal of the proximal member; and a distal member including an outer surface extending between a proximal portion disposed with the distal portion of the intermediate member and a distal portion configured for penetrating fixation with tissue, the distal member being configured for axial translation relative to the intermediate member.
