In general, orthopedic instrument adapters and methods of using orthopedic instrument adapters are provided. In an exemplary embodiment, an adapter is configured to releasably attach to an end effector configured to impact bone. The end effector can be a broach, chisel, or other surgical implement. The adapter includes a spring-loaded hook that is configured to releasably seat in a cut-out formed in the end effector. The adapter is also configured to releasably attach to a surgical impacting tool, such as an orthopedic impactor, configured to drive impacting of the end effector relative to bone.

A device to be used by an operator which may grasp objects in a sterile or non-sterile field, and may facilitate the precise placement and passage of a needle or pin into tissues while using X-ray guidance. The device provides a secure hold while keeping the hands remote from the radiation field, and by permitting non-obstructed viewing of the held instrument and tissues. A radiolucent hammer may be used to help drive a needle into firm tissues without obscuring visualization.

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectoinal areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

A tool assembly includes a universal, intervertebral bone fusion spacer for insertion into a disc space between a first vertebral body and a second vertebral body and fusion of the first vertebral body to the second vertebral body via biological bone fusion and screw fusion, and a tool for manipulating and inserting the universal, intervertebral bone fusion spacer into the disc space between the first vertebral body and the second vertebral body to provide fusion of the first vertebral body to the second vertebral body via biological bone fusion and screw fusion.

A locking tack for attaching a bone fixation device to a bone includes (a) an elongated body including a distal portion formed of a weldable material and sized to be received within a bore through a portion of a target bone and a proximal portion which, when the distal portion is in a desired position within a target bone, extends out of the bone; (b) a channel extending longitudinally through the elongated body from a proximal end thereof to a channel distal end within the distal portion of the elongated body; and (c) an engaging feature at a distal end of the channel configured to engage an extraction mechanism so that forces applied to the extraction mechanism are transmitted to the distal end of the elongated body.
