Abstract: A polyaxial bone anchoring device includes a receiving part having a longitudinal axis, a channel for receiving a rod, and an accommodation space for pivotably holding a head of a bone anchoring element, and a pressure member configured to be positioned in the receiving part and to exert pressure onto the head to lock the head in the receiving part. The pressure member includes a pressure exerting surface and a deformable portion having a free end, wherein the deformable portion is configured to assume at least a first configuration and a second configuration. The polyaxial bone anchoring device further includes a locking member configured to be inserted into the channel and to exert a force onto the deformable portion. When the head and the pressure member and the locking member are in the receiving part, the free end of the deformable portion is supported in the receiving part, and the locking member is movable in the channel along the longitudinal direction in such a manner that the locking member first contacts the deformable portion and exerts a force onto the deformable portion to bring the deformable portion from the first configuration into the second configuration thereby locking the head. Thereafter the locking member comes into contact with the rod and locks the rod.

Abstract: The present disclosure is directed to a method of surgical repair utilizing a continuous compression staple for an orthopedic injury site having a long bone fracture defining a fracture boundary between a first bone fragment and a second bone fragment. The method can include the steps of aligning the fragments, applying a temporary compressive force to the aligned fragments, inserting a compression staple in a tensioned state into the first and second bone fragments such that it traverses the fracture boundary, releasing tension in the compression staple such that the staple exerts a continuous compressive force to the first and second bone fragments, and securing a neutralization implant to the long bone. The disclosure further includes kits and systems for performing the disclosed surgical methods.

Abstract: A radially compressive implant, which includes a central vertical axis, is configured to transition between a natural shape and an insertion shape. A transition of the implant from the natural shape to the insertion shape facilitates the implant storing energy deliverable radially relative to the central vertical axis. A transition of the implant from the insertion shape toward the natural shape facilitates the implant delivering the energy stored therein radially relative to the central vertical axis. An implant delivery device in an implant engagement position is configured to engage the implant and constrain the implant in the insertion shape. The implant delivery device in an implant release position is configured to release the implant.

Abstract: An interspinous process device includes a first plate, a second plate, and a transverse member between the first plate and the second plate, wherein the second plate is adjustably coupled to the transverse member. A post is coupled to the transverse member and a spring mechanism is disposed between the post and the first plate. The spring mechanism is configured to provide a preloaded compression force to the first and second plates. Methods of implanting the interspinous process device using an inserter tool are also disclosed.
