Patent number: 11819247Abstract: The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.Type: GrantFiled: December 17, 2020Date of Patent: November 21, 2023Assignee: DePuy Synthes Products, Inc.Inventors: Thomas Keyer, Joseph Capozzoli, Eric McDivitt

Publication number: 20230338066Abstract: A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.Type: ApplicationFiled: April 21, 2022Publication date: October 26, 2023Inventors: Rohit Shinde, Thomas Keyer, David Cowens, Joshua McManus, Raymond Schmitt, Michael Bushelow, Stanley J.

Publication number: 20230089550Abstract: A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.Type: ApplicationFiled: November 30, 2022Publication date: March 23, 2023Inventors: Josef GABELBERGER, David COWENS, Joshua MCMANUS, Thomas KEYER, Catherine SANTIS, Roberto KHATCHADOURIAN, Peter VAN CITTERS, David W.
