Patent number: 12042185Abstract: A pivotal bone anchor assembly includes a receiver having a central bore with a seating surface adjacent a bottom opening and a downward-facing surface above the seating surface, and a shank having a head portion positionable within the axial bore. The assembly also includes a compression insert positionable within the central bore above the head portion and having an upper portion with a notch formed therein to define a resiliently compressible structure extending over the notch. When the head portion of the shank and the compression insert are positioned together in the central bore of the receiver, the engagement between the resiliently compressible structure and the downward-facing surface is configured to provide an axially directed resilient biasing force for a pre-lock friction fit of the pivotal bone anchor assembly prior to securing the longitudinal connecting member in the open channel with the closure.Type: GrantFiled: July 26, 2023Date of Patent: July 23, 2024Inventor: Roger P.
