Abstract: An expandable cage for intercorporal fusion of lumbar vertebrae comprises a main body with two expandable parallel arms. Each arm has a supporting surface pointing outside and configured to contact an adjacent vertebral body, a groove pointing inside and extending along a transverse direction, and a channel pointing inside and extending along a longitudinal direction. An expansion element is instrument actuated and presses the arms apart expanding the cage. The expansion element is between the arms and comprises a cylindrical base body, two opposing radially aligned ribs on the base body, and a rectangular plate. Both the base body and ribs have curved, pair-wise opposed bearing surfaces. Depending on the cage's expansion state, either the base body bearing surfaces or the rib bearing surfaces contact channels provided in the arms, while the plate engages in the grooves of the arms.

Abstract: An implant for stabilizing bones or vertebrae is provided, the implant comprising an implant body (1, 100, 100?) which can be fixed by at least one screw (2) to the bone or a vertebra, wherein the implant body comprises at least one hole (9a, 9b, 9c, 9a?, 9b?, 900a, 900b?) which has a threaded portion (91) with an internal thread for cooperating with the screw thread, characterized in that a guiding member (11,11?,11?,111) is provided in the hole which guides the screw when the screw is screwed through the threaded portion (91).

Abstract: A fixation device for bones includes a member which has at least one bore for receiving a bone screw, wherein the at least one bore comprises a first internal thread portion. The bone screw has a first shaft section provided with a first external thread portion arranged to cooperate with the internal thread portion of the at least one bore, and a head section having a diameter larger than that of the shaft section to provide a catch arranged to engage with a stop formed in the bore. The bone screw further has a second shaft section which includes a clearance groove extending between the catch of the head section and the external thread of the first shaft section. The clearance groove allows disengagement of the two thread portions, such that the bone screw is prevented from being unscrewed off the bore when it is loosened within the adjacent bone.

Abstract: A polyaxial connector for spinal fixation systems has a lateral connector element having a first receptacle for a polyaxial connection to a spherical head of a pedicle screw and a second receptacle for a polyaxial connection to a spherical head of tulip that is configured to receive a connection rod clamped in the tulip by a locking element. A clamping piece is mounted in longitudinally-movable manner in the connector element between the receptacles. If the locking element is tightened, a pressure ram received in the tulip exerts a clamping force on the pedicle screw head, thereby fixing the connector element to the pedicle screw.

Abstract: An implant for stabilizing bones or vertebrae includes an implant body with at least a first hole and a second hole that can be fixed by a first screw and a second screw. Each of the screws includes a screw thread. Each of the holes has a threaded portion with an internal thread for cooperating with the screw thread, wherein the threaded portion of at least the first hole is formed of a flexible material. A guiding member that is a separate part is insertable into the implant body such that it is arranged at least partially within the first hole. The guiding member is configured to guide the first screw when the first screw is screwed through the threaded portion of the first hole. The second screw is spaced apart from the guiding member when the second screw is screwed through the threaded portion of the second hole.
