  • Patent number: 11219472
    Abstract: A fixation system includes an elongated rod, a fastener, a yoke, and an insert. The fastener includes a head with a truncated top portion. The yoke receives the rod and includes a yoke opening and a yoke cavity. The yoke cavity supports the head allowing for angular movement of the fastener. The insert is inserted into the yoke above the fastener and includes an insert base and a plurality of prongs. The insert base defines a base cavity that provides clearance for the head. The prongs extend away from the insert base and contact the head of the fastener below the truncated top portion. At least one set of the prongs has a length such that when the fastener is moved to a position of maximum angular movement within the yoke, at least one of the prongs is out of contact with the head of the fastener.

  • Patent number: 10973553
    Abstract: A modular pedicle screw assembly has a multi-part cam lock structure for fixing a threaded shank to a head subassembly. A modular pedicle screw assembly provides capture and release of a spherical end of a threaded shank by a head through rotation of closures radially disposed in an internal chamber of the head. Geometry of the closures cooperate with geometry of the internal chamber, providing a selective cam action between the closures and the internal chamber to increase and decrease size of an opening formed by the closures. Closure rotation produces an open state where the spherical end of the threaded shank can pass through the closures, releasing the spherical end of the threaded shank from the head, and a closed state where the spherical end of the threaded shank cannot pass through the closures thereby capturing the spherical end of the threaded shank in the head.

  • Patent number: 10143497
    Abstract: An orthopedic connection assembly is described that comprises a housing member for receiving an implant that is operably connected to a receiving member for receiving an anchor member. The connection assembly is configured to have a locking mechanism that secures and fixes the relative orientation between the implant and the anchor member. The connection assembly can comprise a plate member receivable within the housing member. When a securing member such as a set screw is introduced downwardly into the housing member to secure the implant, the securing member applies a lateral force to the plate member, which presses against an interference member within the receiving member. The interference member presses against the anchor member, such that the anchor member is fixed in a position relative to the implant.

  • Patent number: 10085772
    Abstract: A system for flexibly stabilizing a vertebral motion segment by connecting a first vertebra and a second vertebra is disclosed. The system includes an elongate connection element with end portions interconnected by a flexible coupling member. The system includes first and second attachment portions for connecting the connection element to the vertebrae. A first resilient member is positioned between the first end portion and the first attachment portion, and a second resilient member is positioned between the first attachment portion and the second attachment portion. The system is designed such that the second resilient member is compressed when the first and second attachment portions move towards each other, and the first resilient member is compressed when the first and second attachment portions extend away from each other.

  • Patent number: 9936979
    Abstract: A bone anchor (100) for attaching a rod (108) to a bone has an anchor member (106) for attachment to the bone and an anchor head (104) having a U-shaped opening for receiving the rod. The bone anchor also includes a locking cap (102) that has a main body (900) and a set screw (1000). Advantageously, in one embodiment the locking cap preferably is designed such that a single tool can be used to lock the locking cap in place on the anchor body preferably with a 90° turn and preferably then drive the set screw to clamp the rod. The locking cap also preferably non-threadingly engages the anchor body. The anchor body preferably has an inclined surface on its top surface which elastically deflects extending tabs on the main body to secure the locking cap to the anchor body. A method of implantation and assembly of the bone anchor are also described.

  • Patent number: 9827013
    Abstract: The present invention relates generally to a surgical device for the correction of deformities of the spinal column and finds particular, although not exclusive, utility in devices which are surgically implantable. Presently known implantable surgical devices are unable to provide for the progressive correction of spinal deformities assisted by active movements of the human body without fusion of the involved part of the spinal column. The present surgical device comprises a spinal column straightening means for permitting the relative rotation of two substantially adjacent vertebrae about a common axis substantially only in opposite rotational directions.

  • Patent number: 9820778
    Abstract: A post that is configured to be coupled to a head of a bone fixation element that is attached to a bone part can include a post body that is elongate along a first direction and defines a proximal end and a distal end that is spaced from the proximal end along the first direction. The post body can include an internal surface that defines a socket at the distal end. The socket can be configured to receive the head of the bone fixation element. The post can further include a locking member that is disposed within the socket such that when the socket receives the head of the bone fixation element the locking member couples the post body to the bone fixation element. The post body is polyaxially pivotable relative to the head when the post body is coupled to the bone fixation element.
