ORTHOPEDIC FASTENER, RETAINER, AND GUIDE

摘要

Implants, instruments, and methods for connecting and/or stabilizing first and second bone portions relative to one another are presented including fasteners and retainers connectable in axial force transmitting relationship and instruments for their installation. In one example a guide is configured to clamp two bone portions together while a fastener is inserted through at least one of the bone portions to engage a retainer.

主权项

1. A system operable to fix first and second bone portions relative to one another, the system comprising:
a retainer having a receiver defining a receiver longitudinal axis; a screw threadably engageable with the receiver, the screw having a shaft portion defining a longitudinal axis, the shaft having a distal shaft width dimension perpendicular to the screw longitudinal axis in a width direction, a proximal shaft width dimension perpendicular to the screw longitudinal axis in the width direction, the proximal shaft width dimension being greater than the distal shaft width dimension; and a guide having a handle, a bone contacting member mounted to the handle, a retainer supporting member mounted to the handle opposite the bone contacting member, the retainer supporting member having a portion operable to releasably support the retainer opposite the bone contacting member, the bone contacting member and retainer supporting member being mounted for translation relative to one another and being resiliently biased toward one another, the guide being operable to clamp an object between the retainer and bone contacting member while the screw is engaged with the retainer.
